Study finds early warning signals of abrupt climate change

A new study by researchers at the University of Exeter has found early warning signals of a reorganisation of the Atlantic oceans' circulation which could have a profound impact on the global climate system.

Could climate change shut down the Gulf Stream?

The 2004 disaster movie "The Day After Tomorrow" depicted the cataclysmic effects—superstorms, tornadoes and deep freezes— resulting from the impacts of climate change. In the movie, global warming had accelerated the ...

Study documents slowing of Atlantic currents

While scientists have observed oceans heating up for decades and theorized that their rising temperatures weaken global currents, a new study led by a University of Maryland researcher documents for the first time a significant ...

Ocean current system seems to be approaching a tipping point

The Atlantic Meridional Overturning Circulation (AMOC) may have been losing stability in the course of the last century, a new study by Niklas Boers, published in Nature Climate Change, suggests. The finding is worrying as ...

Fingerprint of ancient abrupt climate change found in Arctic

A research team led by Woods Hole Oceanographic Institution (WHOI) found the fingerprint of a massive flood of fresh water in the western Arctic, thought to be the cause of an ancient cold snap that began around 13,000 years ...

Ocean circulation implicated in past abrupt climate changes

There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ...
