Så här skriver IPCC om skyfall och översvämningar:
The frequency and intensity of heavy precipitation events have increased over a majority of land regions 21 with good observational coverage since 1950 (high confidence, Box TS.6, Table TS.2). Human influence is 22 likely the main driver of this change (Table TS.2). It is extremely likely that on most continents heavy 23 precipitation will become more frequent and more intense with additional global warming (Table TS.2, 24 Figure TS.12 b). The projected increase in heavy precipitation extremes translates to an increase in the 25 frequency and magnitude of pluvial floods (high confidence)

Du citerar alltså summeringen för politikerna som ofta inte speglar vad de riktiga rapporterna innehåller och självklart måste det finnas med prognoser baserade på osäkra klimatmodeller.
Så här säger IPCC:
“heavier rainfall does not always lead to greater flooding.”
“Confidence about peak flow trends over past decades on the global scale is low, but there are regions experiencing increases, including parts of Asia, southern South America, the northeast USA, northwestern Europe, and the Amazon, and regions experiencing decreases, including parts of the Mediterranean, Australia, Africa, and the southwestern USA.”
“there is low confidence in the human influence on the changes in high river flows on the global scale”
Kina har alltid haft många översvämningar. De har även sedan mitten av 1900-talet dödat "alla" sina insekter och fåglar.
