Concentrations of all GHGs continue to rise rapidly. The post 2007 renewed methane increase is a new and worse climate state, due to planetary feedback warming wetland peat methane emissions and some natural gas industry emissions.
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.
New presentation showing all three main greenhouse gases on one graph.
Carbon dioxide’s post 1990 acceleration is sustained.
Methane post 2007 renewed increase due to planetary feedback emissions sustained.
Nitrous oxide still by far the fastest rising greenhouse gas, the most powerful of the 3 GHGs.
