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 year 2014 ranks as Earth’s warmest since 1880, according to two separate analyses by NASA and National Oceanic and Atmospheric Administration (NOAA) scientists. The 10 warmest years in the instrumental record, with the exception of 1998, have now occurred since 2000. This trend continues a long-term warming of the planet, according to an analysis…

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.

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…

Exceptionally mild temperatures in large parts of Europe and stormy UK weather with 100mph winds

2015 takes off with temperatures for parts of Europe hovering around 17C. And The Guardian warned of 100mph gale-force winds and snow to batter the UK. Temperatures in Germany spring like with meteorologists forecasting 17C in Germany Salzburg or in Wien Austria, for tomorrow the 10th of January 2015. Ironically, the ski resort Allgäu tries to…

BOOM: Oil Price Collapse and why it is Important

I recently mentioned, get out of fossil energy while you still can, when the price for crude was at $64.82. Though, today it has approached $55.84, with many oil guys loosing a fortune, oil billionaire Hamm lost half his fortune in three months. And the New York Times noted, free fall in oil price underscores shift…

Royal Society: An introduction to climate change in 60 seconds

Published on Dec 10, 2014: Climate science explained in 60 seconds by the Royal Society and the US National Academy of Sciences. During the last 200 years, human activities such as the burning of fossil fuels have increased concentrations of CO2 in the atmosphere by 40%. If unchecked, continuing emissions will warm up the planet…
