evidence: The specific claim here–that the IPCC scientific reviews find no increase in extremes–is incorrect, as is the broader implication that there is no observational evidence for increasing meteorological extremes. The IPCC Special Report on Managing the Risk of Extreme Events (SREX) directly contradicts the former claim, while a rapidly growing body of scientific research points toward a clear increase in certain types of extreme weather events–especially heat waves, droughts, and heavy downpours (e.g., Diffenbaugh et al. 2017)*. While it is certainly true that some of these extreme events would have occurred naturally (and that not all event types are increasing in all regions), human-caused global warming is exerting an increasingly substantial influence on the risk of global temperature and precipitation extremes. [...] This statement is not true. The IPCC does not say that "there has been no increase in extreme weather events". In the IPCC’s Fifth Assessment Report, in the Physical Science volume, the very first table of the summary document gives a comprehensive, careful and nuanced assessment of different types of extreme weather events and whether there has been an increase in them. The IPCC’s conclusion is that for some types of extreme weather event, such as hot days, heatwaves and heavy precipitation, there have been increases (with varying levels of confidence and likelihood attached to these conclusions, ranging from "very likely" to "medium confidence. For other types of extreme weather events, such as drought and tropical cyclones, there is low confidence in a global-scale trend but nevertheless increases in some more localized regions are likely to have occurred.
