It's not yet possible to quantify exactly how much of a role climate change has played in the heavy rainfall affecting much of England and Wales.
That requires a full scientific analysis of natural and human causes, which can take weeks or months.
But such episodes of intense rainfall have been getting more common as the UK’s climate changes.
According to the Met Office, the UK appears to be getting more “very wet days” – the term used to describe days with at least 10mm (0.4in) of rain.
And scientists at the World Weather Attribution group found that the amount of rainfall on the stormiest days last winter was about 20% higher due to human-caused climate change.
Warmer air can hold more moisture – about 7% for every 1C of temperature rise. This extra moisture can lead to heavier rainfall.
