WMO: Greenhouse Gas Concentrations Reach Record High

Atmospheric greenhouse gas concentrations reached a new record high in 2013, with carbon dioxide (CO2) levels rising more than in any year since 1984, according to the World Meteorological Association’s latest annual Greenhouse Gas Bulletin.

Arctic Monitoring Stations Report CO2 Levels of 400 parts per million

The Arctic region continues to serve as the global climate “canary in a coal” mine. Now, as with average temperature rise, the region is leading into a new troubling milestone as monitoring stations near a remote outpost near Barrow, Alaska are among several such stations to report that average concentrations of CO2 have reached an average of 400 parts per…

CO2 Increasing “Super Exponentially” – A Call for “Evidence-Based Decision Making”

A research paper called Evidence for super-exponentially accelerating atmospheric carbon dioxide growth (pdf) recently published  in the Cornell University Library shows – in great mathematical detail – that atmospheric carbon is increasing “super exponentially” and that human civilization currently consumes planetary resources at the rate of 1.5 earths every year. “This means,” says the report in its introduction, “it now takes the Earth…

UK Scientists Compare Official G8 Proposals To Combat Climate Change With Real Carbon Cycle Data

A few UK scientists have done a smart thing; they’ve combined the proposals of G8 policymakers for combating climate change with actual data on the status of play in the carbon cycle. The resulting study (pdf) is interesting not only because of this highly useful approach but also because it focuses on atmospheric carbon dioxide and its impact on the…
