IPCC 6th Assessment
For the first time IPCC acknowledged that
Extreme weather events are increasing, due to human activities and will continue to increase
IPCC AR6 WR1(science) SPM
Human-induced climate change is already affecting many weather and climate extremes in every region across the globe. Evidence of observed changes in extremes such as heatwaves, heavy precipitation, droughts, and tropical cyclones, and, in particular, their attribution to human influence, has strengthened since AR5
It is certain that hot extremes (including heatwaves) have become more frequent and more intense across most land regions since the 1950s,
Marine heatwaves have approximately doubled in frequency since the 1980s and human influence has contributed to most of them since at least 2006
The frequency and intensity of heavy precipitation events have increased since the 1950s over most land area and human-induced climate change is likely the main driver.
Human-induced climate change has contributed to increases in agricultural and ecological drought
It is likely that the global proportion of major (Category 3–5) tropical cyclone occurrence has increased over the last four
decades, and it is very likely that the latitude where tropical cyclones in the western North Pacific reach their peak intensity
has shifted northward
Human influence has increased the chance of compound extreme events since the 1950s.
This includes increases in the frequency of concurrent heatwaves and droughts on the global scale,
fire weather in some regions of all inhabited continents,
and compound flooding in some locations
