It also found the likelihood of experiencing a similar seven-day amount of rainfall is three times more likely now because of climate change.
The rapid weather attribution study was carried out by climate scientists at the ICARUS Climate Research Centre in Maynooth University, and at Met Éireann.
It says the amount of rain that Storm Chandra brought was not particularly remarkable, with very little change in…
