Weakening Sun would hardly slow global warming
Published Mar 10, 2010 - 10:27:23 AM
A new Grand Minimum of solar activity would decrease the rise of global mean temperature caused by human greenhouse gas emissions only marginally. A new modelling study by researchers of the Potsdam Institute for Climate Impact Research, published online today in the journal Geophysical Research Letters, finds a temperature offset of at most 0.3 degrees Celsius until the end of the century. This is less than ten percent of the temperature rise projected under "business as usual" scenarios of the Intergovernmental Panel on Climate Change (IPCC).

On Rooftops Worldwide, a Solar Water Heating Revolution
Published Mar 9, 2010 - 7:32:28 AM
The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm both water and space.

Russian and Swedish researchers report in Science on significant methane emissions in the Arctic from thawing seabed north of Siberia
Published Mar 8, 2010 - 8:07:56 AM
The powerful greenhouse gas methane is being released into the atmosphere from an area of the East Siberian Sea equivalent to more than four times the area of Sweden. Permafrost in the seabed has been previously assumed to act as an effective cap for the enormous amount of methane in the area, which, if released, could lead to an abrupt global climate warming.

Climate change and human influence
Published Mar 5, 2010 - 9:47:54 AM
A Met Office review of the latest climate research confirms our planet is changing rapidly and man-made greenhouse gas emissions are very likely to be the cause. Long-term changes in our climate system have been observed across the globe, from shifts in rainfall patterns to a decline in Arctic sea-ice. The changes follow the pattern of expected climate change and bear the ‘fingerprint' of human influence, providing the clearest evidence yet that human activity is impacting our climate.
