1 1023 IS A RICHER-BUT-WARMER WORLD BETTER THAN POORER-BUT-COOLER WORLDS? Indur M. Goklany 1 Assistant Director, Science & Technology Policy, Office of Policy Analysis, U.S. Department of the Interior, Washington, DC Ph: ; Fax: ABSTRACT Greater economic growth could lead to greater greenhouse gas emissions, while simultaneously enhancing various aspects of human well-being and the capacity to adapt to climate change. This begs the question as to whether and, if so, for how long would a richer-but-warmer world be better for well-being than poorer-butcooler worlds. To shed light on this issue, this paper draws upon results of the Fast Track assessment (FTA) reported in a special issue of Global Environmental Change: Part A 14 (1): 1 99 (2004), which employed the IPCC s emissions scenarios to project future climate change and its global impacts on various determinants of human and environmental well-being. Results suggest that notwithstanding climate change, through much of this century, human well-being is likely to be highest in the richest-but-warmest (A1FI) world and lower in poorerbut-cooler worlds. With respect to environmental well-being, matters may be best under the A1FI world for some critical environmental indicators through , but not necessarily for others. An alternative analysis using the Stern Review s worst-case results for potential welfare losses due to climate change indicates that welfare, adjusted for market and non-market impacts of climate change and the risk of catastrophe, should be highest under the A1FI scenario, at least through INTRODUCTION 2 One of the conundrums facing the world, which should be addressed in the course of developing climate change policies, is whether, and, if so, for how long, would a richer-but-warmer world be better for human and environmental well-being than a poorer-but-cooler world. This conundrum arises because, unless climate change is modest (IPCC, 2001a; Hitz and Smith, 2004), greater economic growth could, by increasing greenhouse gas (GHG) emissions, lead to greater damages from climate 1 Views expressed in this paper are the author s, and not necessarily those of any unit of the U.S. government. 2 This paper is a modified version of a paper with the same name presented at the 25th North American Conference of the USAEE/IAEE, Denver, CO, September 18 21, 2005.

On the other hand, by increasing wealth, technological development and human capital, economic growth would broadly increase human well-being (Goklany, 2002a), and society s capacity to reduce climate change damages via adaptation or mitigation (Goklany, 1995, 2007a; Yohe, 2001; Smit et al., 2001). Specifically, many determinants of human well-being hunger, malnutrition, mortality rates, life expectancy, the level of education, and spending on health care and on research and development improve along with the level of economic development, as measured by GDP per capita, a surrogate for both per capita income and wealth (or affluence ) (see Figure 1; Goklany, 2002a). Improvements in these determinants are associated with increased human capital and should aid technological diffusion. Increasing wealth would also improve some, though not necessarily all, indicators of environmental well-being, e.g., wealthier nations have higher cereal yield (an important determinant of cropland, which is inversely related to habitat conversion), greater access to safe water and sanitation, and lower birth rates (see Figure 2; Goklany, 2002a, 2007a). 3 Notably, access to safe water and access to

Cross country data also indicate that at any given level of economic development, the previously-noted indicators of human and environmental well-being (e.g., malnutrition, mortality rates, life expectancy, access to safe water, crop yields, and so forth) improve with time, which itself is a surrogate for advances in, and diffusion of, technology (Goklany, 2002a, 2007a). Figure 3 illustrates this time-dependent (or secular) improvement for two of the most important indicators of human well-being, namely, life expectancy and infant mortality. Thus one should expect, ceteris paribus, that society s adaptive capacity should also increase with the passage of time which, barring inadvertent maladaptation, should reduce the future impacts of climate change (Goklany, 2007a). 3 One indicator that, so far at least, has not shown an improvement with wealth is CO 2 emissions. Also, some environmental indicators, e.g., air pollutants such as sulfur dioxide and particulate matter, generally worsen initially as incomes increase before declining at higher income levels (see Goklany, 2002a, and references therein).

Sources: Goklany (2002a, 2007a), based on World Bank (2001) Which Emissions Pathways Are To Be Preferred? Nowadays most assessments of the impacts of climate change use, as a starting point, emissions scenarios developed by the Intergovernmental Panel on Climate Change (IPCC, 2000). Table 1 summarizes the dominant characteristics of the storylines associated with these scenarios (IPCC, 2000) and corresponding estimates in 2085 of atmospheric CO 2 concentrations and climate change used by the Fast Track assessment (FTA) of the global impacts of climate change sponsored by the U.K. Department of Environment, Forests and Rural Affairs (DEFRA). In Table 1, climate change is represented by increases in globally averaged temperature (Arnell, 2004; Arnell et al., 2004). The columns in this, and subsequent, tables are arranged from left to right in the order of decreasing CO 2 concentrations (and global temperature changes), that is, A1FI, A2, B2 and B1. 4 Note that although the IPCC scenarios were intentionally devised as no policy scenarios which presumed no pro-active measures to mitigate or adapt to climate change, many analysts, pointing to the differences in emissions between the various scenarios, claim that we can choose our emissions futures (Schneider 2007). In a similar vein, Hayhoe et al., (2004) writing in the Proceedings of the National Academy of Sciences note 4 The FI in A1FI indicates that this scenario is fossil fuel intensive.

Likewise, Gerald Meehl (2007), in recent testimony to the Committee on Science and Technology, United States House of Representatives, notes that As we approach the middle part of the 21 st century and beyond, it makes a difference regarding what emissions scenario we choose to follow now before elaborating on the differences in projected impacts under the various IPCC scenarios. The implication of these statements is that the A1FI scenario, being the warmest, is something humanity should avoid, if possible. In fact, it could be argued that much of the worldwide activity designed to reduce greenhouse gas emissions is about how human society might be steered towards preferred socio-economic development paths (e.g., building on the logic of the IPCC SRES B1 scenario) (IPCC 2001c: 3; emphasis added). Other analysts may, however, argue that it is not for the global community to choose from A1F1, A2, B2, and B1 scenarios, that we do not know which of these scenarios will unfold although it maybe argued that some of these scenarios are more likely than others. Theoretically, the differences between the scenarios reflect uncertainties about the future development paths for human society and the economy, rather than conscious choices about which path is preferable or which policies to implement. These analysts would point out that the scope for pro-active human intervention lies within each of the scenarios not by choosing between them. But the reality seems to be that the notion that
6 1028 Energy & Environment Vol. 18, No. 7+8, 2007 well-being would be worse in a richer-but-warmer world is, in fact, prompting governments and other institutions to steer the world toward the lower emission scenarios as evidenced, for example, by the recent pronouncements at the G8 Summit (2007) and statements made by President Bush and Secretary General Ban Ki-moon (Knowlton, 2007; United Nations News Centre, 2007). 5 Accordingly, this paper will investigate whether human and environmental well-being will necessarily be worst under the richest-but-warmest of the four worlds characterized by the IPCC s scenarios, while recognizing that given the current state of knowledge, definitive answers are unlikely at this time. The answer will also shed light on the propriety of steering the world toward the lower emissions scenarios if that would also mean lower economic development. However, the analysis undertaken here doesn t tell us whether, how much or what mitigation and adaptation activities should be undertaken to maximize welfare. Such an analysis is outside the scope of this paper The Approach Used in this Paper This paper draws mainly upon peer-reviewed results of the DEFRA-sponsored Fast Track assessment (FTA) of the global impacts of climate change reported in a special issue of Global Environmental Change Part A (volume 14, issue 1, pp. 1 99, 2004). It then uses, as a check, results from the recent Stern Review of the economics of climate change (Stern Review 2006). With respect to hazards affecting human well-being, the FTA analyzed hunger (Parry et al., 2004), water stress (Arnell, 2004), coastal flooding (Nicholls 2004), and malaria (van Lieshout et al., 2004). With respect to environmental well-being, the FTA projected net biome productivity (a measure of the strength of the terrestrial biosphere as a carbon sink), and the global extent of coastal wetlands and croplands (Levy et al., 2004). For the most part, global climate change impacts were estimated through 2085 or is probably at the outer limit of the foreseeable future since socioeconomic scenarios are not deemed credible beyond that (Arnell et al., 2002). Like the FTA, this paper does not consider low-probability but potentially highconsequence outcomes such as a shut down of the thermohaline circulation or the melting of the Greenland and Antarctica Ice Sheets. They are deemed unlikely to occur during this century (see, e.g., DEFRA, 2004; IPCC, 2007). Table 1 suggests that, on one hand, the impacts of climate change should decrease as one goes from scenario A1FI on the left to B1 on the right (in accordance with the pattern of declining climate change, ceteris paribus). On the other hand, since economic development and the rate of technological change are both critical determinants of adaptive capacity (Goklany, 1995, 2007a; Smit et al., 2001; Yohe 2001), these impacts ought to be attenuated through a combination of autonomous and pro-active adaptations. Considering future levels of economic and technological development (see Table 1), this attenuation should be greatest for the A1FI scenario, 5 This highlights a fundamental problem with static scenarios purporting to follow specific paths over decades (or longer) regardless of whatever problems and hurdles may be encountered in the future. They assume fatalist human beings. Although this might facilitate paper analyses, they do not reflect real world behavior, as recent events abundantly reveal.
7 Is a Richer-but-Warmer World Better Than Poorer-but-Cooler Worlds? 1029 followed by the B1, B2 and A2 scenarios, in that order. Thus, it is not obvious that although the A1FI scenario has the highest climate change, it would necessarily have the highest damages from climate change (because A1FI should also have the highest adaptive capacity). It has been sometimes argued that the extent to which economic growth increases society s (or another entity s) capacity to reduce climate change damages via adaptation or mitigation, this capacity would depend considerably on the distribution of the determinants of human well being (such as economic growth) between and within countries. For example, if economic growth is concentrated on countries that are already wealthy, as sometimes has been claimed to be the case in recent decades, then today s poorer countries ability to reduce future climate impacts (due to higher adaptive capacity because of economic growth) could be seriously overestimated. While there is some merit to this argument, it should be noted that in the recent past, economic growth in some of the most populous developing countries (e.g., China and India) has outstripped that in developed countries. As a result, income inequalities have, for the world population as a whole, shrunk around the world (Sala-i-Martin, 2007; Bhalla, 2002), as have inequalities between developing and developed countries since the 1950s in terms of determinants of human well-being. 6 More importantly, according to the IPCC scenarios, between 1990 and 2100 income growth in developing countries relative to developed countries will be greater by a factor of 3.6 to 9.4 (IPCC, 2000: 301). Secondly, an examination of Figures 1 and 2 indicates that the dependence of virtually all determinants of human well-being on income is highly non-linear (generally logarithmic) with their improvements occurring much more rapidly at the lowest levels of income (Goklany, 2007a). Thus even a small improvement in income for poor societies (or the poor within a country) could enhance their adaptive capacity more than a larger increase for richer societies (or the rich). Thirdly, over the long haul (say, 50 to 100 years), secular improvements in technology could dominate over increases in income with respect to enhancing adaptive capacity, particularly at low income levels (see Figure 3). The long term impact of technological change is one reason for the remarkable declines 99 percent or greater during the 20th century in mortality and morbidity rates in the United States for various waterrelated diseases, e.g., typhoid, paratyphoid, dysentery, malaria and various gastrointestinal diseases) (Goklany, 2007b: 153; USBC, 1975: 77). Therefore, keeping these considerations in mind, the question must be asked: over the foreseeable future, would the benefits of a richer and more technologically advanced world be cancelled out by the costs of a warmer world? The FTA s results, which this paper uses to help answer this question, are like all other estimates of the impacts of climate change plagued with uncertainties resulting from, among other things, the fact that such estimates are based on a series of linked models with the uncertain output of each model serving as the input for the next model. The first link in the chain of models are emission models which use socioeconomic assumptions extending 100 or more years into the future to generate emission scenarios (see Table 1). 6 For a more nuanced discussion, see Goklany (2007b: Chapter 3).
8 1030 Energy & Environment Vol. 18, No. 7+8, 2007 This information is then converted into radiative forcing which is fed into coupled atmosphere-ocean general circulation models (AOGCMs) to estimate spatial and temporal changes in climatic variables which are, then, used as inputs to simplified and often inadequate biophysical models that project location-specific biophysical changes (e.g., crop or timber yields). Notably, the uncertainty of estimates of climatic changes increases as the scale at which they have to be specified becomes finer. This is particularly true for precipitation, which is a key determinant of the natural resources (e.g., water and vegetation) that human beings and all other living species depend on either directly or indirectly. Unfortunately, the analyses should be done at relatively fine scales because the distribution and status of these natural resources are spatially heterogeneous (as are the socioeconomic factors that would determine spontaneous responses to the impacts of climate change). Next, depending on the human or natural system under consideration, the outputs of these biophysical models may have to be fed into additional models to calculate the social, economic, and environmental impacts on those systems. A major shortcoming of impacts assessments is that the models used at this step do not fully incorporate changes in adaptive capacity due to higher levels of economic development and technological change (see Table 1; more on this below). In other words, the methodology used to estimate impacts under any scenario is not entirely consistent with the underlying assumptions of the particular scenario. Despite the resulting cascade of uncertainties associated with the concatenation of models used to make such impacts assessments and the many legitimate criticisms of the IPCC scenarios (Henderson and Castle, 2003, Carter et al., 2006) underlying the FTA analyses, for the purposes of this chapter I will take the results of the FTA at face value because they: (a) have been peer-reviewed, (b) are state-of-the-art, (c) have figured prominently in the international debate over global warming. The FTA s results for the impacts of climate change on food, agriculture, water resources, and coastal flooding were a prominent part of a symposium, Avoiding Dangerous Climate Change, sponsored in 2005 by the UK Government as a prelude to the 2005 G-8 Gleneagles Summit (DEFRA, 2005). They were also used heavily in the impacts assessment portion of the recent Stern Review of the Economics of Climate Change, and have been referred to quite frequently within the latest (2007) IPCC report on impacts, adaptation and vulnerability. Notably, climate change is only one factor impinging on future human and environmental well-being. Consequently, to answer the question posed in the title of this paper, it is insufficient to examine just the incremental problems caused by climate change (denoted by P) for each of the above-noted climate-sensitive hazards and threats to well-being. To these incremental problems we should add the problems that would exist in the absence of climate change (denoted by P 0 ). Hence, the total problem [P T ] with climate change equals P 0 + P (Goklany, 2000, 2003). Accordingly, in this paper, for each category of climate-sensitive hazard or threat, I will rank the four scenarios according to the magnitude of P r as provided in the FTA analyses before attempting to develop an aggregate ranking for each scenario in order to answer the question whether a richer-but-warmer world is better than poorer-butcooler worlds. Note, however, that this is not the same as asking whether mitigation
9 Is a Richer-but-Warmer World Better Than Poorer-but-Cooler Worlds? 1031 may advance well-being or what is the optimal mix of adaptation and/or mitigation actions for dealing with climate change. Answering these questions requires a different kind of analysis than is undertaken here Nomenclature In the following, in consonance with the FTA, the magnitude of the problem (P) due to each climate-sensitive hazard affecting human well-being, namely, malaria, hunger, water stress and coastal flooding, will be measured by the global population at risk (PAR) or suffering from the specific climate-sensitive hazard. For these hazards, P and PAR will, henceforth, be used interchangeably, as will P and PAR. With respect to environmental well-being, P will be measured by three indicators: (a) global cropland area (an indicator of habitat loss, the most important threat to global terrestrial biodiversity, see, e.g., Green et al., 2005; Goklany, 1998 and references therein), (b) losses in coastal wetlands, and (c) the negative of net biome productivity (a measure of the terrestrial carbon sink capacity). 2. POPULATION AT RISK FOR VARIOUS CLIMATE-SENSITIVE HAZARDS, WITH AND WITHOUT CLIMATE CHANGE This section examines the FTA s estimates of populations at risk with and without climate change (i.e., P 0 and PAR) associated with four climate-sensitive hazards to human well-being, namely, hunger, water shortage, coastal flooding and malaria, in 2085 under each of the four scenarios summarized in Table 1. In our examination of P 0 and PAR under the various scenarios, it should be kept in mind that, firstly, 2085 is, as noted, at the outer limits of the foreseeable future. Secondly, the FTA analyses assumed no new policies and measures to reduce damages from climate change, but it included some, but not all, spontaneous adaptations that could be reasonably assumed to occur (IPCC, 2001a). Accordingly, the FTA analyses have a tendency to simultaneously overestimate negative impacts (see below) while underestimating positive outcomes. 7 This tendency is more pronounced the higher the future adaptive capacity (that is, the higher the level of economic growth and technological change). In other words, the overestimates of net negative impacts are largest for A1FI and least for the A1 scenario. Thirdly, the A1FI and B1 scenarios have the same populations in 2085 (see Table 1). This, however, is an exogenously-imposed assumption within the scenario story lines. In fact, in the real world, lower total fertility rates are generally associated with higher levels of economic development (see, e.g., IPCC, 2000: ; Goklany 2007a). Arguably, therefore, the A1FI world should have a lower population in 2085 than the B1 world, which suggests that emissions and the amount of climate change indicated in Table 1 under the A1FI scenario is further overestimated, relative to the B1 scenario. Moreover, since a higher population would result in a higher population 7 This is self-evidently true for impacts directly impinging on human well-being. It s also valid for environmental impacts to the extent these impacts are also affected directly or indirectly by a population s wealth or technological prowess, e.g., habitat loss or species protection.

Source: Parry et al., (2004). at risk (PAR) for various climate-sensitive hazards, it is conceivable that estimates of both P 0 and PAR for A1FI will have been overestimated relative to the B1 scenario. Hunger. Tables 2 and 3 show the FTA s estimates of PAR for hunger in 2085 both with and without climate change for the various scenarios. Table 2 gives PAR in absolute numbers, while Table 3 provides it as a proportion of the specific scenario s global population. These estimates, taken from Parry et al., (2004), show that whether or not climate changes beyond 1990 levels, no matter which scenario we choose, through 2085 the future world will be better off with respect to hunger than it was in 1990 both in terms of absolute numbers and as a proportion of total population. Second, in 2085, some of the warmer scenarios might actually result in lower levels of hunger, than some cooler scenarios. Third, hunger in 2085 will be lowest in the B1 scenario, followed by A1FI, B2 and A2 (in that order). Thus, the warmest scenario (A1FI) does not lead to the lowest level of well-being. Note, however, that this is not just the consequence of wealth-related adaptive capacity, but also higher CO 2 levels (and, at least in some areas, greater soil moisture). Finally, for some scenarios (A2 and, possibly, B2), climate change might, in fact, reduce the PAR for hunger at least through Notably, Parry et al., s analysis allows for some secular (time-dependent) increases in agricultural productivity, increases in crop yield with economic growth due to greater application of fertilizer and irrigation in richer countries, decreases in hunger due to economic growth, and for some adaptive responses at the farm level to deal with climate change. However, as that study itself acknowledged, these adaptive responses are based on currently available technologies, not on technologies that would be available in the

The potential for future technologies to cope with climate change is large, especially if one considers bioengineered crops (Goklany, 2003, 2007b). 8 Thus the projections of PAR in Tables 2 and 3 are probably overestimates, especially for the A1FI world, which has the highest level of wealth, because yields generally increase with greater wealth (see Figure 2; Goklany, 1998, 2007b). Moreover, as noted previously, the population of the A1FI world might be an overestimate relative to the B1 world. Had these factors been considered, the A1FI scenario might conceivably have resulted in the lowest levels of hunger. Tables 2 and 3 assume that the direct CO 2 effects on crop yields would be realized. If, however, these direct effects are not realized, then Parry et al., s analysis indicates that the climate change would exacerbate the total population at risk under all scenarios, including the A2 and B2 scenarios while PAR would still be less than P 0 for all but the A1FI scenario. But such outcomes are unlikely. First, the probability that direct CO 2 effects on crop growth are zero or negative is quite low, if not non-existent (IPCC, 2001b: ). Second, as already noted, the FTA most likely overestimates 8 It is also unclear how well Parry et al., s analysis accounts for potential increases in overall productivity of the food and agricultural sector that might occur as technologies that are underutilized today become more affordable and are, therefore, likely to be used more broadly with rising incomes. These include technologies that would, for instance, reduce post-harvest and end-use losses that have been estimated at 47 percent worldwide (Goklany 1998, and references therein).
12 1034 Energy & Environment Vol. 18, No. 7+8, 2007 the declines in agricultural yields and as well as the populations at risk with or without climate change because it does not fully account for technological options that would be available to richer and more technologically advanced societies of the future. These tables also confirm that in comparing the consequences of various scenarios, it is not sufficient to examine only the impacts of climate change. One should also look at the total level of hunger. Otherwise, based merely on an examination of PAR, one could conclude, erroneously, that, with respect to hunger, A2 is the best of the four scenarios. But, in fact, based on total PAR, A2 would be the worst. This also illustrates that efforts focused on minimizing the consequences of climate change to the exclusion of other societal objectives might actually reduce overall human welfare. Water Stress. The FTA s estimates of PARs for water stress in 2085 with and without climate change are shown for each scenario in terms of absolute numbers in Table 4, and in terms of the proportion of global population in Table 5 (Arnell, 2004). 9 [A population is deemed to be under water stress if its available water supplies fall below 1,000 m 3 per capita per year.] Both tables indicate that for each scenario, climate change by itself might, in fact, reduce the total PAR for water shortage. Note that PARs in Tables 4 and 5 account for the fact that because of climate change some populations will move out of the water stressed category, while other populations will move into that category. However, Arnell (2004) and a derivative paper (Arnell 2006) in a book titled, Avoiding Dangerous Climate Change, tend to emphasize the increase in the population under water stress due to climate change over the decrease in that population. Specifically, after acknowledging that If the absolute numbers of people living in waterstressed watersheds was taken as the indicator of water resources stress, then climate change would appear to reduce global water resources pressures because more watersheds move out of the stressed class than move into it he argues that would give a misleading indication of the effect of climate change: Firstly, the increases in runoff generally occur during high flow seasons, and may not alleviate dry season problems if this extra water is not stored: the extra water may lead to increased flooding, rather than reduced water resources stresses. Secondly, the watersheds that apparently benefit from a reduction in water resources stress are in limited, but populous, parts of the world, and largely confined to east and southern Asia: areas that see an increase in stress are more widely distributed. (Arnell 2004: 50). While Arnell s second argument is not persuasive if one is interested in estimates of the total global population at risk (as is this study), his first argument only highlights the fact that in contrast to Parry et al., s study on hunger, his water stress estimates exclude any spontaneous or proactive adaptations that might be undertaken, albeit at some cost, to alleviate future water shortages. Specifically, 9 Arnell (2004) also uses the 10-year return period minimum annual runoff as a measure of water availability. Even under this variation, climate change relieves water stress (compared to the no climate change condition). However, his paper does not provide estimates using this measure of the population in 2085 living in countries where water availability would fall below 1,000 m 3 /capita/year assuming climate change. Hence, those results are not shown in Tables 4 or 5.

The low (high) end numbers are based on an assumption of low (high) subsidence. P 0 = PAR in the absence of SLR; PAR = change in PAR due to SLR; Total PAR = P 0 + PAR. Source: Nicholls (2004).

Source: Nicholls (2004). these estimates do not consider either current or future adaptive capacity. as a function of economic progress or secular (i.e., time dependent) technological development. One should expect that at least a portion of the available options for alleviating water stress (and forestalling human and economic losses to floods) would be undertaken even in a business-as-usual world, particularly since such measures are known, have been implemented for centuries, and will only become more affordable as future populations become wealthier per the SRES scenarios (see Table 1), and with secular (i.e., time dependent) advances in technological prowess (Goklany 2007a). Consequently, Arnell s analysis not only overestimates the populations living in water stressed areas, his rationale for highlighting the increased population at risk of water stress (at the expense of the population with reduced risk) is unpersuasive, at best. Tables 4 and 5 also show that in the absence of climate change, A1FI and B1 have the smallest PAR in 2085, while A2 generally has the highest. This is true in terms of both absolute numbers and the fraction of total population for the relevant scenario. The reason why in the absence of climate change, the A1FI and B1 scenarios have identical PARs is due to the population assumptions built into the story lines, which seem unrealistic in light of experience. Third, with climate change, the A1FI world continues to have the lowest PAR but that for B1 falls to second place (both in terms of absolute numbers, and a fraction of the global population).
14 1036 Energy & Environment Vol. 18, No. 7+8, 2007 Fourth, for each scenario, P 0 exceeds PAR in 2085, that is, with respect to water shortage, non-climate change related factors are more important than climate change, at least through the foreseeable future. As noted, Arnell (2004) did not consider any adaptation, although several supply side and demand side adaptations are currently available that would reduce PAR for water shortage whether or not climate changes (see, e.g., Goklany, 1998, 2000, 2007b). Moreover, one should expect that the wealthier societies of 2085 will be better able to afford and, therefore, would be more likely to employ such adaptation technologies than are today s relatively poorer societies, particularly if, in the meantime, water shortages are heightened, as indicated in Tables 4 and 5. Therefore, had Arnell s (2004) analysis considered adaptations, the PAR estimates would have been reduced for each scenario. These reductions would have been greatest for the A1FI (richest) scenario and lowest for the A2 (poorest) scenario and, although the ranking among the scenarios would not change, the differences in PAR between the various scenarios would have been magnified. Coastal flooding. Table 6, which is based on Nicholls (2004), provides the Fast Track Assessment s estimates of the PAR for coastal flooding with and without any sea level rise between 1990 and In this Table, PAR is measured by the average number of people who would experience coastal flooding by storm surge in 2085 with and without climate change, assuming that the coastal population grows twice as fast as the general population (or, if populations are projected to drop, it drops at half the pace of the general population), and evolving protection with a 30-year lag time. The low and high end of the ranges for PAR for each entry in Table 6 assume low and high subsidence due to non-climate change related human causes, respectively. Table 7 provides the same information as in Table 6, but as a proportion of the global population in 2085 for each scenario. Nicholls (2004) makes a creditable effort to incorporate improvements in adaptive capacity due to increasing wealth. Nonetheless some of its assumptions are questionable. For instance, Nicholls allows societies to implement measures to reduce the risk of coastal flooding in response to 1990 surge conditions, but they ignore subsequent sea level rise (Nicholls, 2004, p. 74). But one would expect that whenever any measures are implemented, they would consider the latest available data and information on the surge situation at the time the measures are initiated. That is, if the measure is initiated in, say, 2050, the measure s design would at least consider sea level and sea level trends as of 2050, rather than merely the 1990 level. Nicholls also allows for a constant lag time between initiating protection and sea level rise. But one should expect that if sea level continues to rise, the lag between upgrading protection standards and higher GDP per capita will be reduced over time. Moreover, it is conceivable that the richer a society the faster this reduction. In fact, if the trend in sea level rise proves to be robust, it is possible that protective measures may be taken in advance, i.e., the lag times may even become negative. In addition, Nicholls (2004) does not allow for any deceleration in the preferential migration of the population to coastal areas, as might be likely if coastal flooding becomes more frequent and costly. But if the preferential migration continues
15 Is a Richer-but-Warmer World Better Than Poorer-but-Cooler Worlds? 1037 unabated, it would not be implausible to expect a country s expenditures on coastal protection to increase as its coastal population also increases relative to its total population. A plausible adjustment would be to increase such expenditures on a per- GDP basis as the fraction of the population in coastal areas rises. Such an outcome would not be inconsistent with democratic governance. Nicholls (2004, Table 7) also suggests that subsidence is more likely under the A1FI and A2 worlds than the B1 and B2 worlds. Although this assumption conforms with the SRES s narratives regarding the priority given to environmental issues, it contradicts real world experience which indicates that once richer countries are convinced of a problem, whether it is environment or health related, they generally respond quicker to remedy the problem, spend more, and have greater environmental protection than poorer ones, especially at the high levels of development that, as indicated in Table 1, are projected to exist virtually everywhere later this century under all the IPCC s scenarios (see also Goklany, 2002a). Hence, one should expect that the richest (A1FI) world would spend more and be better protected from subsidence, than would the B1 or B2 worlds. If greater concern for the environment, in fact, translates into a higher fraction of GDP spent on the environment then, despite spending a smaller fraction under A1FI, total spending on and the amount of coastal protection could be higher under that scenario than, say, the B1/B2 scenarios, given the wide gaps in GDP per capita between these scenarios. Putting aside these shortcomings, Tables 6 and 7 show that in the absence of climate change, the PAR for coastal flooding in 2085 under the A1FI and B1 worlds would be lower than what it was in 1990, but it would be higher under the A2 world; and it may or may not be higher under the B2 world. With climate change, the PARs would increase under each scenario with A2 having the highest total PAR by far, followed, in decreasing order, by B2, and perhaps A1FI and B1. Notably, the difference in PAR between A1FI and B1 scenarios is not very large, considering the several assumptions, noted above, that tend to downplay the adaptive effects of wealth. Malaria. Van Lieshout et al., (2004) reported on the FTA s analysis for malaria. However, they only provide numerical estimates for changes in global PAR due to climate change (i.e., PAR) under the various scenarios, but not for PARs in the absence of climate change, or for total PARs with climate change. 10 But, as noted, the scenario with the highest PAR does not always have the highest total PAR, a much more relevant measure of human well-being. Moreover, although van Lieshout et al., (2004) attempt to include adaptive capacity as it was in 1990, they do not adjust for changes in adaptive capacity over time, i.e., with advances in economic and technological development, as ought to occur between 1990 and Thus, their analysis sheds no light on the issue of whether well-being (as measured by the population at risk for malaria) would be greater in a richer-but-warmer world as compared to a poorer-but-cooler world. 10 This author contacted various co-authors of the van Lieshout et al., paper to obtain their results for PAR with and without climate change, but to no avail.
16 1038 Energy & Environment Vol. 18, No. 7+8, 2007 However, the results of an earlier (pre-sres) assessment of the global impact of climate change on the PAR for malaria (Martens et al., 1999) that were also sponsored by DEFRA and whose authors included the co-authors of van Lieshout et al., (2004) allows us to get an idea of the relative contribution of climate change to the total population at risk for malaria in That earlier analysis used a business-as-usual scenario that was developed for the 1995 IPCC impact assessment, and did not include any additional greenhouse gas controls. The UK Meteorological Office s HadCM2 model projected that under that scenario, the globally averaged temperature would increase by 3.2 ºC between 1990 and 2085 (Parry et al., 2001), which approximates the temperature increase using HadCM3 under the A2 scenario (see Table 1). That study s results for malaria also reported in Arnell et al., (2002) indicate that the global population at risk of malaria transmission in the absence of climate change (P 0 ) would double from 4,410 million in 1990 to 8,820 million in 2085, while PAR in 2085 would be between 256 million and 323 million. In other words, climate change would contribute only a small portion (about 3.2 percent) of the total PAR for malaria in 2085 (Goklany, 2003). Note that these PARs for malaria transmission are substantially larger than the numbers of people who would actually contract or die from that disease in any given year. By comparison with the P 0 of 4,410 million in 1990, the number of people who actually contracted malaria each year in the 1990s was an order of magnitude lower ( million), while the number who died (about 1 million) was smaller by more than three orders of magnitude (WHO, 1999). One reason for these differences is that the actual prevalence of malaria does not coincide either with its historical or potential range based on the presence of the malaria transmitting vectors and/or the malaria parasite. This, in fact, reaffirms the importance of incorporating adaptive capacity and changes in adaptive capacity due to economic growth and technological change into impact assessments. The current range of malaria is dictated less by climate than by human adaptability, and despite any global warming that might have taken place over the past century (or more), malaria has been virtually eradicated in richer countries although it was once prevalent there (e.g., the U.S. and Italy) (Goklany, 2000, 2007b). This is because, in general, a wealthier society has better nutrition, better general health, and greater access to public health measures and technologies targeted at controlling diseases in general and malaria in particular. In other words, today s wealthier and more technologically advanced societies have greater adaptive capacity, and that is manifested in the current geographic distribution of malaria prevalence around the globe (Goklany 2007a). In fact, analysis by Tol and Dowlatabadi (2001) suggests that malaria is functionally eliminated in a society whose annual per capita income reaches $3,100. But Table 1 indicates that under the poorest (A2) scenario, the average GDP per capita for developing countries is projected to be $11,000. Hence, few, if any, countries ought to be below the $3,100 threshold in Moreover, given the rapid expansion in our knowledge of diseases and development of the institutions devoted to health and medical research, one can be relatively confident that the $3,100 threshold will almost

ECOLOGICAL CHANGES IN , WITH AND WITHOUT CLIMATE CHANGE Table 8, based on Levy et al., (2004) and Nicholls (2004), provides information on the variation in three specific ecological indicators across the different scenarios. One indicator is the net biome productivity (a measure of the terrestrial biosphere s net carbon sink capacity). The second indicator is the area of cropland (a crude measure of the amount of habitat converted to human use). Notably, land conversion to agricultural uses is perhaps the single largest threat to global terrestrial biodiversity (Goklany, 1998). The third indicator is the global loss of coastal wetlands relative to 1990 levels. The biosphere s sink capacities under the A1FI and A2 scenarios are approximately the same, at least through Largely because they result in higher CO 2 concentrations, their sink strengths are greater compared to the B1 and B2 scenarios and, at least through 2100, the positive effect of carbon fertilization under the A1FI scenario

Partly for the same reason and also because of its low population, the amount of cropland is lowest for the A1FI world, followed by the B1 and B2 worlds. (Cropland estimates were not provided for the A2 scenario.) Thus, through 2085, the A1FI scenario would have the least habitat loss and, therefore, pose the smallest risk to terrestrial biodiversity from this particular threat, while the B2 scenario would have the highest habitat loss. With regard to the loss of coastal wetlands, the estimated loss due to sea level rise (SLR) for each scenario is quite substantial but the contribution of climate change to total losses in 2085 are smaller than losses due to subsidence from other man made causes, confirming the results of earlier studies (Nicholls 1999). According to Table 8, wetland losses are much higher for the A1FI and A2 scenarios than for the B1 and B2 scenarios. This is due mainly to the assumption that the first two scenarios would have higher non-climate change related subsidence (Nicholls 2004, p. 76) but, as noted, this assumption is suspect. 4. DISCUSSION: IS A1FI THE WORST SCENARIO FOR HUMAN AND ENVIRONMENTAL WELL-BEING? Results Based on the Fast Track Assessment For each indicator for which data were provided in the foregoing, Table 9 ranks the four scenarios according to the level of human or environmental well-being per that indicator for both the climate change and the non-climate change cases. In this ranking scheme, 1 indicates the best level of well-being while 4 indicates the worst. If two scenarios show the same level of well-being then they share the same ranking. For example, in the absence of climate change, scenarios A1FI and B1 are both ranked at the top with respect to water stress in 2085 (because they both have
19 Is a Richer-but-Warmer World Better Than Poorer-but-Cooler Worlds? 1041 the same low population in 2085). Accordingly, they split the number one and two rankings, and their joint ranking is indicated as 1.5. Table 9 assumes that the relative ranking of the scenarios with respect to GDP per capita (a surrogate for per capita wealth or income) will be maintained despite any climate change. This is likely because the differences in GDP per capita from one scenario to the next for either developing or developed countries are quite large (see Table 1) by comparison to the equivalent reduction in consumption due to climate change through (IPCC, 2001). If there is any change in ranking, examination of Table 9 indicates that the most likely change with respect to GDP/capita would be A1FI and B1 trading places. But considering that the differences in average GDP per capita in 2100 between the A1FI and B1 scenarios range from 47 to 65 percent (for developed and developing countries, respectively; see Table 1), it is unlikely that any drop in equivalent consumption by 2100 due to climate change will close the differences in GDP per capita between the A1FI and B1 scenarios. 11 Perhaps serendipitously, the rankings are the same whether one uses absolute numbers or the proportion of global population as the measure of the impact of climate change. The top part of Table 9 provides rankings for various indicators of human wellbeing (HWB) in 2085, namely, wealth (for which GDP per capita is a surrogate), hunger, water stress, and coastal flooding. If one considers that: (a) GDP per capita or perhaps more accurately, the logarithm of GDP per capita (Goklany, 2002a, 2007a; Figures 1 3) should probably be given greater weight because it is a surrogate for numerous, and more appropriate, HWB indicators (e.g., life expectancy, mortality rates, access to safe water and sanitation, and level of educational attainment), and (b) impacts analyses have a general tendency (discussed previously) to underestimate changes in adaptive capacity as a function of both economic development and technological progress (or time), then Table 9 suggests that HWB in 2085 would, in the aggregate, be highest for the A1FI scenario and lowest for A2. Reinforcing this conclusion is the possibility that compared to the B1 scenario, populations at risk for the A1FI scenario might be overestimated (as might the amount of climate change). Applying the same logic and considerations, it would seem that HWB should be somewhat better under B1 than B2. These aggregate rankings would stay the same whether or not climate changes, or whether they are based on PAR in terms of absolute numbers or the proportion of global population. The last three rows of Table 9 rank scenarios based on the three environmental indicators addressed in Section 3 (and Table 8). Based on the strength of the terrestrial carbon sink and cropland area, environmental quality would be superior under the A1FI scenario than under either the B1 or B2 scenarios through 2100, but these rankings would 11 For instance, the Stern Review estimated that unmitigated climate change will reduce welfare by an amount equivalent to a reduction in consumption per capita of 5 20 percent now and forever if one accounts for market and non-market impacts and the risk of catastrophe (Stern Review, 2006, Executive Summary, p. x). Although several researchers have disputed the Review s impacts estimates as overblown (Byatt et al., 2006; Carter et al., 2006; Dasgupta, 2006; Nordhaus, 2006; Tol and Yohe, 2006) and the Review s authors themselves emphasize strongly that the numbers should not be taken too literally (Stern Review, FAQ, 2007, p. 2), if one accepts its estimates, then at most consumption would be reduced in 2100 by 20%, which is less than the 47 65% differential between the A1FI and B1 scenarios.

[Sources: Warren (2006b), Arnell et al., (2004), World Bank (2006); Stern Review (2006). apparently be reversed for coastal wetlands, at least through 2085 apparently, because, as noted, that could be an artifact of the assumption that subsidence should/would be lower under the B1 and B2 scenarios than the A1FI scenario. Results Based on the Stern Review s Analysis. An alternative approach to determining whether the A1FI scenario is necessarily the worst of the four worlds depicted by the IPCC scenarios is to use the results of the Stern Review. The Stern Review estimated that unmitigated climate change will reduce welfare by an amount equivalent to a reduction in consumption per capita of 5 20 percent now and forever if one accounts for market and non-market impacts and the risk of catastrophe (Stern Review, 2006, Executive Summary, p. x). It also suggests that by the year 2200 the 95th percentile of the equivalent per capita GDP losses could rise to 35.2 percent (Stern Review, pp. 156 and 158). Several researchers have disputed the Review s impacts estimates as overblown (Byatt et al., 2006; Carter et al, 2006; Dasgupta, 2006; Nordhaus, 2006; Tol and Yohe, 2006) and the Review s authors themselves emphasize strongly that the numbers should not be taken too literally (Stern Review, FAQ, 2007, p. 2). I will, nevertheless, put aside these concerns and, in this section, be guided by the Review s results in order to estimate whether unmitigated climate change will lower future well-being to below today s (1990)

The REE turnaround has arrived and this time it's here to stay
Shares of Molycorp (NYSE: MCP) and Lynas Corp (ASX: LYC) surged yesterday and today when compared to the lackluster performances seen during most of last June. Lynas reached over AUD$0.45/share in Sydney trading while Molycorp crossed the USD$7 barrier at USD$7.08 share yesterday. Given that there were no significant announcements from either one of the two only existing rare earths producers in the 'West', the main explanation is to be found in the Chinese government's action to cut domestic rare earths production, especially by targeting illegal miners, in conjunction with a perception of higher demand, especially in key markets such as Japan. China, which has repeatedly tried to gain more power over the prices of coveted raw materials, especially rare earths, had actually tested the limits of diplomacy by adopting confrontational international trade policies. It has clearly loosened the rigid policies in the past months and Chinese exports of rare earths have risen thanks to the lower prices.
The encouraging, if rollercoaster like, performance of the Japanese economy has also encouraged demand for the coveted minerals. In addition, European companies have started to buy rare earths again as their reserves have slowly been running out. It is certainly possible to use the term 'turnaround' more confidently now. And the time is right as prices for rare earths worldwide are still low, in 2013 they were 80% lower than the same time in 2012, but this buyer's bonanza may soon turn in favor of the seller. The REE market was burdened by the Chinese export blockade and by the international legal proceedings adopted to challenge them, resulting in an overall climate of tension and mistrust.
Get our daily investorintel update
Prices for rare earths from Chinese production did fall in recent weeks by some 10%, but worldwide demand has increased since the start of 2013 by 7% to 107,000 tons. If this sounds familiar, it is because ProEdgeWire suggested as much in an article published exactly two weeks ago, when hints of Molycorp's current rally, and the relevant explanations, first appeared. Lynas's share performance, moreover, suggests that Molycorp's market rise is not a speculative fluke and that demand for rare earths can be expected to increase in the near future, because the prices of the products are low and end users are reaching the bottom of their inventories. Many end users according to Lynas's CEO, Eric Noyrez, last purchased their stocks of REE's in 2010. Lynas has already completed the first phase of its Lynas Advanced Materials Plant (LAMP) in Malaysia. The second phase, which will be characterized by a stability of production, has already begun but Noyrez suggested that Lynas has no plans to increase production yet, even if it has the capacity. An increase would only occur after rare earths prices themselves increase.
As for a general REE price indication; in 2011, prices bubbled and grew too high. In the past months, REE prices have fallen too low and perhaps the market has now started to move toward a more reasonable plateau, which will prompt producers to optimize capacity at current levels for the next few months at least. Perhaps, in this still uncertain economy, especially in the OECD zone, this is what best accounts for a 'turnaround', whose most optimistic indication is that the REE market has seen the bottom and survived to tell about it.
That bottom may actually have been reached in January, even if the market did not see it, because the steady upward trend in Chinese exports of REE's started in February and Chinese customs data suggests that REE exports increased such that in the first four months of 2013, the country exported nearly 6,112 tons of these commodities – that's almost half of the total REE exports recorded in 2012. It turns out that fears of strained trade relations between Japan and China over the diplomatic dispute around sovereignty of the Senkaku/Diayou Islands failed to disrupt what both countries have shown to be of far greater importance to them now: economic growth. Japanese investment in China did drop in relation to Japanese investment in South East Asia, but not by much and there were no bilateral sanctions or direct boycotts.
The situation is ripe for speculators and bargain hunters to rush back to the REE's, driving prices up. The crucial element here is that this is the second time around. The REE market speculators and the experts have gathered considerable experience and the rise, should it materialize, will be more substantial and less prone to bubbles and bursts. Surely, prices will fluctuate up and down, but the upswings will be more frequent and the downturns less dramatic. The second coming of the REE market rise will be a steadier affair and a long term phenomenon. While China still has the production capacity, giving it monopoly power, the United States with Molycorp and Australia with Lynas and a host of juniors in North America and Australia steadily leading their projects through the phases needed to reach production; Beijing understands that it can no longer use the policies of the past.

Pretty Pooped!
The booth look great all loaded up with inventory, and my earrings hanging on their picture cards were a big hit.
I do think that people were hit with some sticker shock when they looked at my necklaces. This was definitely not the place for those pieces!
Mostly, what I moved were earrings and silk scarves: I sold 3 times what I expected for such a short, small event, and had a great time doing it. Sweet! (But, really, I didn't really know what to expect at all going into it.) Yesterday's crowd was a steady stream of buyers, while today's was a huge crowd of lookers - a completely different vibe. (I'm so grateful for yesterday's results!)
Saturday, my floor helper was friend, Debbie. She's funny and has a lot of retail experience, working in a local art gallery. Today's Gal Pal was pocketbook designer, Christie. Both spent a lot of time chatting up the customers, wearing the merchandise, and hawking it around the rest of the show.
I've got the show bug again so I'll be looking for future venues for sure. BUT, I'll also be hitting the gym - I was so out of shape, even for half-days. I really shouldn't have been this tired. Time to whip my ever-widening butt into shape!
