BBC News - Siberian permafrost thaw warning sparked by cave data
http://www.bbc.co.uk/news/science-environment-21549643

Evidence from Siberian caves suggests that a global temperature rise of
1.5C could see permafrost thaw over a large area of Siberia.

A study shows that more than a trillion tonnes of the greenhouse gases CO2
and methane could be released into the atmosphere as a result.

An international team has published details in the journal
Science<http://www.sciencemag.org/content/early/2013/02/20/science.1228729>

The evidence comes from analysis of stalactites and stalagmites in caves
along the "permafrost frontier".
