Despite recent media reports, there’s no imminent threat, says Columbia geologist Einat Lev.
Ancient humans migrated out of Africa to escape a drying climate, says a new study—a finding that contradicts previous suggestions that ancient people were able to leave because a then-wet climate allowed them to cross the generally arid Horn of Africa and Middle East.
A team of scientists has found new evidence to bolster the idea that the Permian Extinction, which occurred 252 million years ago, was caused by massive volcanic eruptions in what is now Siberia.
A thousand years ago, powerful Viking chieftans flourished in Norway’s Lofoten Islands, above the Arctic Circle. In an environment frequently hovering on the edge of survivability, small shifts in climate or sea level could mean life or death. People had to constantly adapt, making their living from the land and the sea as best they could.
The rise of the Vikings was not a sudden event, but part of a long continuum of human development in the harsh conditions of northern Scandinavia. How did the Vikings make a living over the long term, and what might have influenced their brief florescence? Today, their experiences may provide a kind of object lesson on how changing climate can affect civilizations.
The better climate models become, the harder it is to use them. One team of researchers is working to fix that.
A new look inside the ice sheet validates predictions that it probably won’t melt as quickly as its neighbor—good news, since East Antarctica contains enough water to raise sea levels by 200 feet.
With its mission complete, the Rosetta-Ice Project will give scientists an unprecedented look at the Ross Ice Shelf and how it’s changing with the climate.
In this video, Lamont-Doherty Earth Observatory researchers Robin Bell, Radley Horton, and Adam Sobel explain their research and how it can help improve adaptation practices and make our homes, livelihoods, and the systems we rely on more resilient to extreme weather and sea level rise.
A new study analyzing storm intensity and impacts in the New York metro area aims to inform how communities can better prepare for winter storms and enhance resiliency as the effects of climate change exacerbate hazards.
