Results from a new climate reconstruction of how Antarctica's ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment ...

For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University of Missouri researcher ...

The way the ocean transported heat, nutrients and carbon dioxide at the peak of the last ice age, about 20,000 years ago, is significantly different than what has previously been suggested, according to two new studies. The ...
