Abrupt ice age climate changes behaved like cascading dominoes

Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades. When certain parts of the ...

The climate changed rapidly alongside sea ice decline in the north

Researchers from the Niels Bohr Institute, University of Copenhagen have, in collaboration with Norwegian researchers in the ERC Synergy project, ICE2ICE, have shown that abrupt climate change occurred as a result of widespread ...

Earth's anthropogenic carbon dioxide increase is unprecedented

A new measurement technology developed at the University of Bern provides unique insights into the climate of the past. Previous CO2 concentrations in the atmosphere could be reconstructed more accurately than ever before, ...

Examining how early humans responded to climate change

Kevin Uno is a paleoclimatologist and Lamont Assistant Research Professor at Lamont-Doherty Earth Observatory who studies the role climate change plays in human population dynamics and migration.

Abrupt shifts in Arctic climate projected

Researchers from McGill University project that as the permafrost continues to degrade, the climate in various regions of the Arctic could potentially change abruptly, in the relatively near future. Their research, which ...

Sea ice plays pacemaker role in abrupt climate change

A new study looking at variations in past sea ice cover in the Norwegian Sea found the shrinkage and growth of ice was instrumental in several abrupt climate changes between 32,000 and 40,000 years ago.
