The
number of extreme heat waves has increased several-fold due to global warming [45]--[46], [135] and will increase further if temperatures continue to rise.
According to the latest science, in most cases (
outside of extreme heat waves) the connections between today's extreme weather events and human - driven climate change range from weak (hurricanes) to nil (tornadoes)-- and the dominant driver of losses in such events is fast - paced development or settlement in places with fundamental climatic or coastal vulnerability.
While the 2003 heat wave was unusual in today's climate, 23 Europe is highly likely to face even hotter summers more often in coming decades.24 Scientists estimate that human activities have already at least doubled the
risk of an extreme heat wave.25
Millions of people will suffer, die and be displaced as a
result of extreme heat waves, sea - level rise as much as 100 cm by 2100 with continuing large rates of rise, and by more severe storms, droughts and floods.
