The making of Antarctica

One of the big mysteries in the scientific world is how the ice sheets of Antarctica formed so rapidly about 34 million years ago, at the boundary between the Eocene and Oligocene epochs.

There are 2 competing theories:

The first explanation is based on global climate change: Scientists have shown that atmospheric carbon dioxide levels declined steadily since the beginning of the Cenozoic Era, 66 million years ago. Once CO2 dropped below a critical threshold, cooler global temperatures allowed the ice sheets of Antarctica to form.

"It doesn't mean there's no life on Mars, but what it does mean is it's going to be harder to find," said Jacqueline Goordial, the ��ֱ�� researcher who led the study, in an interview with Rachelle Solomon on CBC's Breakaway.

Failure to find active microbes in coldest Antarctic soils has implications for search for life on Mars

Natural Resource Sciences professor Lyle Whyte and postdoctoral fellow Jackie Goordial talk about their research which suggests that it is unlikely that it is unlikely that there is any microbial life to be found on Mars.
