Month: August 2012

2 August, 2012 – Antarctica was very warm indeed some 52 million years ago …

It is just a bit more than two years since I made my last post here, and since we had the sampling party to take the material from our fantastic expedition back home.

Today, the first major scientific results of our endeavour were published in the journal Nature. The team led by Jorg Pross, which included myself and my graduate student Claire Huck, found amazing evidence from spores and pollen in the very old cores we recovered. These cores reached back to the early Eocene, a time which is often described as part of the ‘Greenhouse world’. Atmospheric carbon dioxide concentrations were a lot higher back then, probably similar to what we would get when burning all our fossil fuels.
