Published on Nov 8, 2012: Suggestions that modest increases in sea ice around Antarctica offset significant losses in Arctic sea ice are based on a bogus “apples and oranges” comparison. Through interviews with a range of respected experts, Peter Sinclair’s newest Yale Forum video explains why such suggestions do not stand up to scientific scrutiny. Related…

The U.S. Geological Survey Gas Hydrates Project Release URL | Access date: January 3rd 2014. Climate studies in the USGS Gas Hydrates Project have become increasingly important since 2007 and focus on the impact of Late Pleistocene to contemporary climate change on the stability of methane hydrate deposits. The goal is to determine how much, if any,…

Australia has just sweltered through its hottest year on record, according to the Bureau of Meteorology. Average temperatures were 1.20 degrees Celsius above the long-term average of 21.8C, breaking the previous record set in 2005 by 0.17C. Professor Karoly: “In the model experiments, it is not possible to reach such a temperature record due to natural climate…

First published on YouTube Sep 9, 2012: Because of global warming, permafrost — the frozen ground that covers the top of the world — has been thawing rapidly over the last three decades. But there is cause for concern beyond the far north, because the carbon released from thawing permafrost could raise global temperatures even…
