Greenhouse Gases Hit Record High The concentration of greenhouse gases in the atmosphere hit a record high in 2011, the United Nations' World Meteorological Organization (WMO) reported Tuesday (Nov. 20).
Chief among these heat-trapping gases is carbon dioxide (CO2), the biggest culprit behind global warming. Carbon dioxide levels reached about 390.9 parts per million last year, which is 140 percent of the pre-industrial level of 280 parts per million and nearly 2 parts per million higher than the 2010 carbon dioxide level, according to the WMO report. Full report:

Shhh!  No scientific data like this or time lapsed photos of melted glaciers please.  Our filthy fossil fuel folks need to keep their monopoly on energy that has been making them filthy rich, and ever richer and richer.
  We have clean alternatives:  solar, wind, geothermal and hydrogen which can now be produced cheaply with free sunlight and no use of electricity in a process called artificial photosynthesis .  GM, Hyundai, Toyota, Mercedes-Benz, Fiat and Volkswagen all have hydrogen autos ready to go and Europe is installing refueling stations.  Not us.  One of Obama's energy czars killed hydrogen research as soon as he could in 2008.  He knows who has the dough if not common sense.
