Sea ice crashes
Sea ice crashes - AMEG was right
AMEG was right to warn the world that without action the sea ice would collapse. The world now is in a dire state and only immediate drastic action can cool the Arctic and hold off catastrophe.
The image below is an edit from a larger image, illustrating the dramatic fall of the sea ice over the past few weeks and showing Arctic sea ice extent (total area of at least 15% ice concentration) for the last 7 years, and compared to the average 1972-2011, as calculated by the Polar View team at the University of Bremen, Germany.

From AMEG news release:
AMEG has recently warned of increased climate extremes and a global food crisis that will deepen as the Arctic warms. This year’s severe drought in the US is not an isolated event; much of the world has been afflicted by extreme weather in one form or another, with floods and droughts impacting agriculture. Such extremes have been on the increase. Recent research by scientists, such as Dr Jennifer Francis of Rutgers University, shows convincing evidence that this increase is related to dramatic warming of the Arctic and changing polar jet stream behaviour.
Droughts and floods have been gradually increasing in intensity for a great many years, as the IPCC AR4 report (2007) predicted would occur with global warming. However the Arctic is warming faster than the rest of the planet. This has weakened the jet stream, increasing the frequency and duration of warm/dry spells and cool/wet spells, and thereby making matters much worse. This year we have seen widespread crop failures and a rise in food prices*. Unless emergency measures are immediately taken to cool the Arctic and restore the sea ice, one can expect an ever worsening food crisis in years to come, with the prospect of famine on a biblical scale.
There are other serious repercussions of sea ice disappearance and Arctic warming, such as a disintegration of the Greenland Ice Sheet to cause massive sea level rise. But AMEG has chosen to focus on methane escalation and the food crisis because they can be seen to be already under way, with apocalyptic results if Arctic warming continues unabated.
AMEG’s conclusion is that we have a planetary emergency as a result of the downward spiral of sea ice. Only by grasping the nettle and applying geoengineering with great determination, as in a war effort, do we have a chance of remedying the situation before it is too late. International collaboration to fight this common “enemy” of Arctic meltdown must bring all nations together, simply in the cause of survival.

Saving the Arctic Ice
Nathan Currier describes responses to the emergency in the Arctic in the post Saving the Arctic Ice: Greenpeace, Greenwashing and Geoengineering (#1), concluding that geoengineering will have to be part of the action.
