Warming United States Heat Waves2007 371(Medina-Ramon and Schwartz, 2007) findings suggest that increases in heat-related mortality due to global warming are unlikely to be compensated for by decreases in cold-related mortality and that population acclimatisation to heat is still incomplete.
Anthropogenic United States Heat Waves2012 60Top (Duffy and Tebaldi, 2012) of observations and climate model results shows that previously rare (5th percentile) summertime average temperatures are presently occurring with greatly increased frequency in some regions of the 48 contiguous United States...this result is more consistent with the consequences of increasing greenhouse gas concentrations than with the effects of natural climate variability
Anthropogenic India Heat Waves2019 3(Vittal et al., 2019) heat waves over India have been increasing in frequency and severity during recent decades, and are responsible for thousands of deaths...The conditions in the Atlantic that drove these heat waves were exacerbated by greenhouse gas emissions rather than natural forcing.
