Böttcher, Pierre LeMetayer, Apratim G. Dastidar and L. Felipe Opazo doi:10.1130/G34183.1 Abstract The Late Triassic mass extinction event is the most severe global warming-related crisis to have affected important extant…

NASA: Projected U.S. Temperature Changes by 2100

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…

Why Global Warming Should Keep You Awake at Night: Dr. Jennifer Francis Gives Chilling Testimony to Congress

Via Robertscribbler: In a July 18 testimony to Congress, Dr. Jennifer Francis, an atmospheric scientist from Rutgers and key innovator to understanding how climate change has brought about dangerous alterations to the Northern Hemisphere Jet Stream, provides five compelling reasons why we should all be quite concerned about human caused global warming. They include: 1.…

Antarctic Methane Emissions

METOP-2 imagery reveals that there is a significant area of high methane concentration over Antarctica. A study paper from 2012 reported that as glaciers melt, gas could belch into atmosphere. Potential Methane Reservoirs Beneath AntarcticaAug. 29, 2012 — The Antarctic Ice Sheet could be an overlooked but important source of methane, a potent greenhouse gas,…

Stable Antarctic Permafrost Melting Faster than Expected

University of Texas: July 24, 2013 AUSTIN, Texas — For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a…

The rise of digital currency like Bitcoin, and carbon footprints

Here i take a look at the rapidly growing Bitcoin currency and technological developments in light of emissions targets. Above video shows a Bitcoin rig June 2011, many computer’s with GPU’s (high power graphic cards), hence high energy consumption. Recent developments David Gilson from Coin Desk writes on June 6th, 2013: We have just observed…

Most Comprehensive Paleoclimate Reconstruction Confirms Hockey Stick

By Stefan Rahmstorf via Scilogs The past 2000 years of climate change have now been reconstructed in more detail than ever before by the PAGES 2k project. The results reveal interesting regional differences between the different continents, but also important common trends. The global average of the new reconstruction looks like a twin of the…
