• Geologic Methane Seeps From Thawing Cryosphere

    • Date: 22/05/12

    Geologic methane is seeping through the edges of thawing permafrost and receding glaciers in Alaska and Greenland, according to a study recently published in the journal Nature Geoscience. University of Alaska Fairbanks researcher Katey Walter Anthony led the study, which, for the first time, documents the widespread occurrence of these terrestrial sources of geologic methane […]

  • Seagrasses Can Store as Much Carbon as Forests

    • Date: 22/05/12

    Researchers find that the global carbon pool in seagrass beds is as much as 19.9 billion metric tons. Seagrasses are a vital part of the solution to climate change and, per unit area, seagrass meadows can store up to twice as much carbon as the world’s temperate and tropical forests. So report researchers publishing a paper […]

  • Are Sinks of CO2 Not Able to Keep Up with Emissions?

    • Date: 21/05/12

      The CO2 emitted by our society into the atmosphere is shared between the oceans, terrestrial biosphere, and atmosphere. Over the last several years an impression has been generated in the scientific literature that the capacity of the oceans and terrestrial biosphere to take up continuing emissions of CO2 shows signs of weakening. We make […]

  • Is The Stratosphere Responsible For Global Warming?

    • Date: 15/05/12

    Variations in ozone in the lower stratosphere could be the main reason for the global warming seen in the past few decades, according to a new paper in press at the Journal of Atmospheric and Solar-Terrestrial Physics. It is claimed that the new model is capable of explaining 82% of the total Earth temperature variability. […]

  • New Paper Confirms Little Ice Age Was A Global Phenomenon

    • Date: 09/05/12

    A paper published today in Geophysical Research Letters confirms that “the Little Ice Age was a global event, probably caused by a change in solar [activity] and volcanic forcing [activity].” The paper finds that Greenland and Antarctica cooled synchronously, although to different magnitudes, suggesting to the authors that climate feedbacks operate differently in the Northern and […]

  • Grand Solar Minimum Caused Global Cooling

    • Date: 08/05/12

    An abrupt cooling in Europe together with an increase in humidity and particularly in windiness coincided with a sustained reduction in solar activity 2800 years ago. Scientists from the German Research Centre for Geosciences GFZ in collaboration with Swedish and Dutch colleagues provide evidence for a direct solar-climate linkage on centennial timescales. Using the most […]

  • Global Warming Heats Up Tornado Debate

    • Date: 07/05/12

    Speculation is rife that a recent glut of killer tornadoes is a sign of rising temperatures. What’s the evidence? LAST year was a particularly deadly year for tornadoes in the US, with the second highest death toll in 137 years. Already this year, major outbreaks have killed 63 people. All eyes are now on May, when […]

  • False Alarm: Greenland’s Glaciers May Contribute “Significantly Less” To Sea-Level Rise Than Thought

    • Date: 04/05/12

    Greenland’s glaciers are not speeding up as much as previously thought, researchers have estimated. As a result, the ice rivers may be contributing “significantly less” to sea-level rise than had been thought. Previous studies had estimated that the nation’s glaciers would double their flow by 2010 and continue to maintain that speed, they explained. But […]
