Warmest ever week of sea temperatures recorded

Irish waters off the west coast saw unprecedented marine temperatures in June of up to 5C higher than normal.

The warmest-ever week for sea surface temperatures has become the latest unenviable record to fall as a result of the climate crisis.

According to the EU's Copernicus Climate Change Service (C3S), the average daily global sea surface temperature reached 20.96C, breaking the previous record set in 2016.
