A world with this much CO²: lessons from 4 million years ago

With Dr Chris Brierley, UCL Geography In Spring last year, carbon dioxide concentrations passed 400 parts per million in the atmosphere — a level not seen since the Pliocene era (3-5 million years ago), and perhaps not even then. We know that the Pliocene was a warm world without glacial cycles, and that the climate…

NASA, NOAA Find 2014 Warmest Year in Modern Record

The Discovery of Abiotic Methane – A New Methane Hydrate Source (News Roundup)

A reservoir of abiotic methane has been discovered in the Arctic Ocean. This means that there is more of the greenhouse gas trapped under the seabed than previously thought.

Once you have a release of fracking fluid into the environment, you end up with a radioactive legacy

Recent studies link radioactive compounds to fracking. This was first made public back in 2010, with the conclusion ‘Fracking’ Mobilizes Uranium in Marcellus Shale. Now a new study aimed to better understand cumulative effects of natural occurrences and new anthropogenic pathways, through fracking-drilling. Indoor radon levels in Pennsylvania have been slowly rising since 2004, around the…
