Global Warming or Climate Change

Study of Siberian permafrost caves shows global warming of just 1.5C 'would pump out a TRILLION tonnes of methane and CO2 U.N. studies show global temperatures have already risen by 0.7C  Huge increase in levels of CO2 could accelerate global warming  Infrastructure built on top of permafrost across the world would collapse Governments currently committed to no more than 2C climate change By  DAMIEN GAYLE PUBLISHED:  12:26 GMT, 22 February 2013  |  UPDATED:  14:59 GMT, 22 February 2013 A temperature rise of just 1.5C is likely to release vast amounts of greenhouse gas into the atmosphere from melting permafrost, new evidence suggests. In Siberia alone, the mighty thaw would liberate more than 1,000 gigatonnes of carbon dioxide and methane, experts warn. The extra levels of greenhouse gas are potentially enough to accelerate global warming. Natural ecosystems and human infrastructure would also be seriously disrupted.

LOS ANGELES – In 1961, President John F. Kennedy asserted that the United States “should commit itself to achieving the goal…of landing a man on the moon and returning him safely to earth,” by the end of the decade. The National Aeronautics and Space Administration accepted the challenge. From 1969 to 1972, NASA’s Apollo program achieved six manned landings on the moon – missions that expanded human knowledge, stimulated economic growth, bolstered America’s geopolitical standing at a critical time, and inspired people worldwide.
