How Close Are We to Climate Tipping Points?
Will overshooting 1.5°C of warming push us over climate tipping points, triggering irreversible and abrupt changes?

How Will Climate Change Impact the Gulf Stream?
Evidence suggests that this major ocean current, which influences the weather in parts of Europe and the U.S., is already changing.

Carbon Lurking in Deep Ocean Threw Ancient Climate Switch, Say Researchers
A million years ago, a longtime pattern of alternating glaciations and warm periods dramatically changed, when ice ages suddenly became longer and more intense. Scientists have long suspected that this was connected to the slowdown of a key Atlantic Ocean current system that today once again is slowing. A new study of sediments from the…

Changes in Ocean ‘Conveyor Belt’ Foretold Abrupt Climate Changes by Four Centuries
Led by Lamont-Doherty researchers, a new study is the first to measure the time lags between changing ocean currents and major climate shifts.

Sluggish Ocean Currents Caused European Heat Wave Some 12,000 Years Ago
New study suggests we may be underestimating the chances of extreme heat and droughts in Europe under climate change.

Could Climate Change Shut Down the Gulf Stream?
In the 2004 disaster movie “The Day After Tomorrow,”, global warming accelerated the melting of polar ice, disrupting circulation in the North Atlantic Ocean and triggering violent changes in the weather. Could climate change shut down the Gulf Stream?

Researchers Model Differences in East Coast Sea Level Rise
For years, scientists have been warning of a so-called “hot spot” of accelerated sea-level rise along the northeastern U.S. coast. But accurately modeling this acceleration as well as variations in sea-level rise from one region to another has proven challenging. Now new research offers the first comprehensive model for understanding differences in sea level rise…

In Greenland, Exactly Where Meltwater Enters the Ocean Matters
In southern Greenland in summer, rivers have been streaming off the ice sheet, pouring cold fresh water into the fjords. A new study tracks where that meltwater goes—with surprising results.
