World is facing a natural resources crisis worse than financial crunch
Juliette Jowit, The Guardian
The world is heading for an "ecological credit crunch" far worse than the current financial crisis because humans are over-using the natural resources of the planet, an international study warns today.

The Living Planet report calculates that humans are using 30% more resources than the Earth can replenish each year, which is leading to deforestation, degraded soils, polluted air and water, and dramatic declines in numbers of fish and other species. As a result, we are running up an ecological debt of $4tr (£2.5tr) to $4.5tr every year - double the estimated losses made by the world's financial institutions as a result of the credit crisis - say the report's authors, led by the conservation group WWF, formerly the World Wildlife Fund. The figure is based on a UN report which calculated the economic value of services provided by ecosystems destroyed annually, such as diminished rainfall for crops or reduced flood protection.

The problem is also getting worse as populations and consumption keep growing faster than technology finds new ways of expanding what can be produced from the natural world. This had led the report to predict that by 2030, if nothing changes, mankind would need two planets to sustain its lifestyle. "The recent downturn in the global economy is a stark reminder of the consequences of living beyond our means," says James Leape, WWF International's director general. "But the possibility of financial recession pales in comparison to the looming ecological credit crunch."...

Thoreau Is Rediscovered as a Climatologist
Cornelia Dean, New York Times
Henry David Thoreau endorsed civil disobedience, opposed slavery and lived for two years in a hut in the woods here, an experience he described in “Walden.” Now he turns out to have another line in his résumé: climate researcher.

He did not realize it, of course. Thoreau died in 1862, when the industrial revolution was just beginning to pump climate-changing greenhouse gases into the atmosphere. In 1851, when he started recording when and where plants flowered in Concord, he was making notes for a book on the seasons.

Now, though, researchers at Boston University and Harvard are using those notes to discern patterns of plant abundance and decline in Concord — and by extension, New England — and to link those patterns to changing climate.
