It all depends on the current of the Atlantic Ocean. Study published this Wednesday quantifies, for the first time, how temperatures would be in different scenarios: cold extremes may reach -34ºC.
Temperatures in Europe can go down significantly and Brussels can reach the 21 ° C negativeIf the Atlantic Ocean current regulating the European climate collapse or weakens, warns a study released on Wednesday.
Concerned is the current that regulates the European climate, known by the acronym AMOC (Atlantic Southern OverTurning Circulation) and that scientists say they are slowing due to global warming.
According to the study, from the Real Meteorological Institute of the Netherlands and the University of Utrecht, Geophysical Research Letters, Brussels can live 19 days a year with maximum temperatures below zero.
More storms and more “bipolar” climate
Scientists and researchers who if the amoc reaches a spot It can lead to a colder Europe in a warmer world. The new study quantifies, for the first time, how European temperatures would be in different scenarios of the Atlantic current and climate change.
In the framework presented, the Portuguese capital does not appear among the most affected cities.
However, according to René Van Westen, author of the study, average temperatures in winter in some European cities may go down 15ºC and the Cold extremes may reach -34ºC In Copenhagen, -29ºC in Berlin and -18ºC in Paris.
In the United Kingdom and Ireland, the cold extremes could reach -19 ° C in London, almost -30 ° C in Edinburgh and -22 ° C in Dublin, with the Arctic ice layer covering parts of the British islands.
With a weaker amoc and a temperature increase of two degrees above the pre-industrial time there will be a cooling of Europe because a weaker chain leads to the expansion of the North Atlantic marine ice block. AND there will also be an increase in winter storms and higher daily temperature fluctuationsexplains in the study.
“Each fraction of grade global warming brings us closer to the collapse of the Amoc. Our new study shows that this would lead Europe to the other extreme-a future of intense cold,” says René Van Westen quoted in the document. And adds:
“Our study is another strong warning to EU political decision makers that, to avoid a climate catastrophe, they must follow the council of European Scientists Scientists for climate change and reduce emissions by 90-95% by 2040. We have to urgently reduce greenhouse gas emissions“.
AMOC carries warm waters north along the Atlantic surface and carries cold and deep waters, providing heat and nutrients to the colder regions and transferring carbon to the bottom of the sea.
This helps regulate European temperatures and mild temperatures are partly due to this current. The slowdown would disturb heat transport to the north, leading to cooling from Europe.
In 2023, a thermal map released by NASA showed, in the middle of a colorful planet of red and orange, a Bluish stain In the ocean region near Canada and Granelândia, revealing milder temperatures.

The “cold bubble” began to be observed about a decade ago and the most consensual theory to date is due to the slowdown in a global oceanic circulation system exploited by the new study, AMOC.
The study was released at a time when in Nice, France, the third world ocean conference, which brings together political decision makers from around the world and aims to mobilize for the importance of the oceans and the degradation to which they are subject.
