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.

Abrupt Climate Change explained by Jim White, 12 Minutes excerpt (@AGU 2014)

Climate is changing as humans put more and more greenhouse gases into the atmosphere. With CO2 levels today around 400ppm, we are clearly committed to far more climate change, both in the near term, and well beyond our children’s future. A key question is how that change will occur. Abrupt climate changes are those that…

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…

Naomi Oreskes – The Key Strategy Of The Merchants Of Doubt: Attacking The Consensus

Naomi Oreskes is an American historian of science and Affiliated Professor of Earth and Planetary Sciences at Harvard University. In 2010 she co-authored Merchants of Doubt which describes how the tobacco industry wrote the handbook on using doubt to delay legislative action against the harms of tobacco. The same book also chronicles how the same…

Siberian Arctic permafrost decay and methane escape

Widespread seafloor gas release from the seabed offshore the West Yamal Peninsula, suggests that permafrost has degraded more significantly than previously thought.  Gas is released in an area of at least 7500 km2 in water depths >20 m.((Offshore permafrost decay and massive seabed methane escape in water depths >20 m at the South Kara Sea shelf | http://onlinelibrary.wiley.com/doi/10.1002/grl.50735/abstract | Alexey Portnov,…

NASA | 2014 Warmest Year On Record

The year 2014 now ranks as the warmest on record since 1880, according to an analysis by NASA scientists. Nine of the 10 warmest years since modern records began have now occurred since 2000, according to a global temperature analysis by scientists at NASA’s Goddard Institute for Space Studies in New York. 2014’s record-breaking warmth…

Rivers of meltwater on Greenland’s ice sheet contribute to rising sea levels

Using satellite and field work after an extreme melt event in Greenland, a UCLA-led study finds that melt-prone areas on its ice sheet develop a remarkably efficient drainage system of stunning blue streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean. However, the team’s measurements at the ice’s edge show that…
