Compared to the IPCC AR5, in the AR6, evidence of observed changes in weather and climate extremes and their attribution to human influence have been strengthened. Human-induced climate change has been affecting many weather and climate extremes worldwide. With further global warming, the frequency and intensity of hot extremes, heavy precipitation, agricultural and ecological droughts in some regions, and the proportion of intense typhoon (hurricane) are projected to increase. Projected percentage changes are larger for the frequency of rarer events. These findings again raise the necessity and urgency to address climate change as well as weather and climate extremes.

Key words: Weather and climate extremes, Attribution, Projection, IPCC AR6
