March 2014 Atmospheric Greenhouse Gases

GHGs March 2014

Atmospheric CO2 continues its exponential increase, and  is now virtually at 400 parts per million.

Methane’s renewed post 2007 increase is now a new increased trend, which according  the latest science is due to methane emissions from warming wetlands (tropical and subarctic) and some fugitive emissions from the expanding natural gas industry. Methane is now at 1850 parts per billion which is more than a two and a half times increase since industrialization. The highest methane level is much higher still, recorded as 2015 parts per billion in Northern Alberta- at the southern edge of the vast Canadian northern wetlands.

Nitrous oxide continues to increase at the fastest rate of the three main GHGs.

Greenhouse gases 31 August 2013

All greenhouse gases are increasing as fast as ever.

They are far above their 800,000 year maximum.

Post 2006 atmospheric methane renewed increase is sustained, due to feedback type methane emissions from warming wetland peat- Far North and tropical. Note the Arctic temperature has been increasing rapidly. This is almost certainly an established methane feedback situation, an extreme new planetary danger.
