Weather that was once considered extreme is becoming the "new normal", according to the latest Met Office report on the UK's climate. It shows the hottest day of the year in the south of England is now typically 4.5C warmer than it was in 1961-1990.
The scientists say that the country's climate is "on the move" as northern areas of Britain now see warmer temperatures that used to only affect southern England.
We can all perceive this year how things have changed.
It can only be hoped that the further extremes of climate change can be averted.
