In total 7.4 cubic kilolitres of water fell, that is the equivalent of filling Lochness, the largest lake in the UK.

Since October 2020, the Met Office have done another attribution study. This looks at how likely this rainfall event would be in the natural environment with no human would happen once in 300 years!

But, due to manmade climate change, we now know that the chances of this event happening today, in our current climate, is once in every 100 years. That's two and a half times more likely.

What's worse is if we continue at the current rate of emissions, by the end of the century it's likey to thappen one in every 30 years, 10 times more likely!

We know that a warmer atmosphere holds more moisture and we are set to get more extreme weather as the planet warms. The extremes of very wet and very dry has huge impacts on us in the UK by damaging infrastructure and services impacting our health and our homes.
