Earth Overshoot Day 2010

According to the UK based think-tank The New Economics Foundation and the California based Global Footprint Network, we blew our global resource budget for this year on August 21st(http://www.neweconomics.org/press-releases/world-enters-ecological-debt-on-saturday-21-august-2010 ).

This is month earlier than last year
(I blogged about it here http://environmentchaos.blogspot.com/2009/09/earth-overshoot-day-2009.html) reflecting the beginning of the recovery from the recent economic crisis and also the increased economic power of upcoming nations which are adopting the northern consumer based lifestyle.

So we are now living on ecological credit....

Just waiting for the crash.

A small foretaste?

We are having some dark days at the moment. The devestating floods in Pakistan,the Russian forest fires, and now the breakaway of a 260 sq km iceberg from the Petermann Glacier on Greenland (http://www.guardian.co.uk/environment/2010/aug/07/biggest-ice-island-greenland).

The breakaway of the huge iceberg is unusual and apparently the largest such event since 1962. It seems uncertain whether the event was directly caused by climate change or not.

But with report last year
(http://www.guardian.co.uk/environment/2009/mar/11/greenland-channels-ice-loss) that the greenland ice sheet was riddled with channels which might speed up the degradation of the ice sheet, it seems ominous.
It raises concerns about sea level rise and also the possibility of a Younger Dryas like cold snap (http://en.wikipedia.org/wiki/Younger_Dryas).

I suppose the really scary thing is that these are all real possibilities and may well be a foretaste of what is to come. As the hypocrisy, disagreement and finger pointing happens at Bonn, it is worth all of us remembering this.
