Latest temperature data from Met Eireann shows that March is becoming colder in Ireland when temperature records from the past four years are compared with the long term average. This will mean longer winters as we have had in 2020 and later growing seasons.
In 2016, the EU warned that :
A warming of the climate is expected to result in an earlier start of the growing season in spring and a longer duration in autumn. The date of the last frost in spring is projected to advance by about 5–10 days by 2030 and by 10–15 days by 2050 throughout most of Europe
Which shows how hard it is to predict the future climate. We, here in Ireland, actually experienced the opposite, prolonged winters and delays to the start of the growing season.
