evidence: Each of the following selected projections are from the IPCC special report. In most instances, climate-related risks for natural and human systems were found to be higher, often significantly so, under the hotter temperature threshold. The degree of these risks depends on many factors, such as the rate, duration and magnitude of warming; geographic location; levels of development and vulnerability; and on how humans respond through adaptation and mitigation options. Some regions, such as small island states, will experience multiple climate-related risks that compound upon each other. [...] People in river basins, especially in the Middle and Near East, will be particularly vulnerable. [...] Impacts will vary by region due to many factors such as the ability of populations to adjust to changes in their environment, vulnerability of populations, their human-made surroundings and access to air conditioning.
