This month has seen widespread flooding on almost every continent, from the U.S. to China, from India to Italy, in extraordinary events that climate scientists say have been made more extreme by human-induced climate change. The World Meteorological Association says global mean surface temperatures are already 1.2 degrees Celsius higher than the pre-industrial average.
But research by the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences (CAS) and the UK Meteorological (Met) Office, published today in the journal Science Advances, indicates that most communities will experience even more extreme wet conditions with each degree of temperature rise.
So it’s not that countries will necessarily have much more rain on average; it’s that we’ll see rain events becoming heavier and less predictable.
The research also implies that rather than floods necessarily becoming more frequent, heavier rainfall could make them more destructive.

Send another scum-bag oligarch to space (sort of) or build more nukes or fund more research - it's all the same to our Lord & Slaver the MPP.

The storm was described as an “extreme phenomenon” due to the sheer volume of water that descended in less than 24 hours. In fact, it’s been identified as the most intense storm the nation has seen since data collection began in 1930.
The future aftermath of this storm could lead to a significant geographical shift in the region. Experts have begun to hint at the potential formation of permanent lakes in certain areas affected by the deluge.
The torrents from the storm were so powerful that they wreaked havoc on infrastructure, roads, bridges, homes, and businesses. Vassilis Kikilias, the Climate Crisis and Civil Protection Minister, conveyed the gravity of the situation in a press briefing on September 6. Satellite imagery offers a stark view of the catastrophe, revealing enormous areas of Greece’s agricultural lands submerged.
Extreme atmospheric rivers (EARs) are responsible for most of the severe precipitation and disastrous flooding along the coastal regions in midlatitudes. However, the current non-eddy-resolving climate models severely underestimate (~50%) EARs... using an unprecedented set of eddy-resolving high-resolution simulations from the Community Earth System Model simulations the EARs are projected to increase almost linearly with temperature warming. Under the Representative Concentration Pathway 8.5 warming scenario, there will be a global doubling or more of the occurrence
"I've never seen scenes like this before. Even during previous typhoons, it was never this severe. It's quite terrifying," said Hong Kong assistant nurse Connie Cheung, 65.
