Gulf Stream Weakening Will Mean More Severe Weather for Ireland, Study Predicts

Ireland is represented in an international team of researchers who have identified a possible link between human-caused climate change and a weakening of the Gulf Stream.

And as The Irish Times reports, a continued weakening of the Atlantic Ocean current system could mean more extreme weather for Ireland — and an end to our typically mild climate.

The researchers’ study, published in journal Nature Geoscience, used a variety of sources to plot the history of the flow of the Gulf Stream: the Atlantic Ocean current that pulls warm water from the equator north while pushing colder water south and, via its extension as the North Atlantic Drift, gives Ireland and the UK our mild, wet weather.

Maynooth University’s Dr Levke Caesar, lead author on the study, said the team combined three different types of data — including deep-sea sediment samples dating back many centuries — to reveal “a robust picture of the overturning circulation” in the Atlantic.

It’s this picture that’s a worrying one for climate scientists, as it shows a distinct weakening of the Gulf Stream’s flow since the mid 20th century, and a trend that suggests it could reach a tipping point by the end of this century.
