How does gulf stream work
This slowing will have a cooling effect but the temperature will still increase in the region overall. It suggests that the British Isles, especially western regions, will see a significantly smaller temperature increase than other areas of land mass.

In fact, England is about the same distance from the equator as cold regions of Canada, yet England enjoys a much warmer climate. The Gulf Stream is caused by a large system of circular currents and powerful winds, called an oceanic gyre.
There are five oceanic gyres on Earth. This world map shows the five oceanic gyres and how they impact ocean circulation. Credit: NOAA. The ocean is constantly in motion, moving water from place to place via currents.
Scientists are increasingly concerned about tipping points — large, fast and irreversible changes to the climate. Boers and his colleagues reported in May that a significant part of the Greenland ice sheet is on the brink , threatening a big rise in global sea level.
Others have shown recently that the Amazon rainforest is now emitting more CO2 than it absorbs, and that the Siberian heatwave led to worrying releases of methane. A major report from the Intergovernmental Panel on Climate Change, due on Monday, is expected to set out the worsening state of the climate crisis.
Ice-core and other data from the last , years show the AMOC has two states: a fast, strong one, as seen over recent millennia, and a slow, weak one. The data shows rising temperatures can make the AMOC switch abruptly between states over one to five decades.
Pushing a chair alters its position, but does not affect its stability if all four legs remain on the floor.
