Global Warming fears rise as Arctic Melt yields huge Atmosphere Methane Rise

advertisement

Atmospheric concentrations of methane (CH4) , a greenhouse gas more than 20 times more potent than carbon dioxide, have risen for the first time in eight years, prompting further serious global warming fears

Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

Key quote from article about linkage of Anatarctic warming linkage to man-made greenhouse gas pollution, QUOTE: "Research published in Nature Geoscience last week found the first evidence that the rise in Antarctic temperatures in recent decades was caused by human-induced emissions of greenhouse gas. The research, led by British scientist Nathan Gillett, compared temperature rises at the Arctic and Antarctic since 1900 with four computer simulations. Only models that factored in man-made emissions were able to reproduce the changes observed in the real world. This is a step on from last year's UN Intergovernmental Panel on Climate Change report, which identified evidence of man-made climate change on every continent except Antarctica."

We need an emergency response to these methane greenhouse gases, an unintended result that is far worse than the original c o gases, which telescopes our demise, if we do not get control of the corporate class forces that are sitting on their hands.

You are correct Eric - indeed a whole bunch of Australian Climate Action Groups (including the Melbourne-based Yarra Valley Climate Action Group to which I belong) this year formed the Climate Emergency Network that demands emergency action NOW to REDUCE atmospheric CO2 as recommended by top US climate scientist Dr James Hansen (Head, NASA's Goddard Institute for Space Studies) (see "Climate Emergency Network": Climate Emergency Network ). Unfortunately corporate greed coupled with mainstream media and politician cowardice, dishonesty and irresponsibility is preventing requisite urgent action and even denying the appalling reality.

This is indeed very worrying, since all that permafrost in Northern Canada will be a great source of methane when it thaws, too. We need some way to harvest all that methane for fuel.

      Methane release into the atmosphere may be the culprit behind the period of extreme global warming called the Paleocene-Eocene thermal maximum (PETM) approximately 55.5 Million years ago.
