DEAR SIR: In relation to climate change, there is much made by the EPA and others about weather extremes in Ireland. Extremes are also cited in the CCAC Annual Review 2019, just issued.

Hurricane Ophelia, for example, is often described as extreme in the media, “Met Éireann issued a status red warning 48 hours in advance of the storm’s arrival: an unprecedented move at the time.” The colour-coded warnings system was first introduced in Met Éireann in April 2012, so it was unprecedented only in the previous five years.
