From the BBC:
The Met Office predicts that by 2070, winters in the UK will be up to 30% wetter than they were in 1990 and that rainfall will be up to 25% more intense.
Summers will actually get drier overall – with more heatwaves and droughts – but when rain does come it will be heavier, 20% more intense than it was in 1990.
Wetter winters always likely as I mentioned recently, but it looks like summers might actually get drier. You’d hope with wetter winters that our reservoirs would be full enough to prevent water shortages during hotter, drier summers. That might require our government(s) to properly invest in our ageing infrastructure though.
I also personally wouldn’t mind wetter winters in exchange for warmer, sunnier and drier summers. That’s basically a Mediterranean climate.
