Because the economic questions involved have received relatively little attention, I have been writing a nontechnical book for people who would like to see how market-based approaches could be used to formulate policy on climate change. When I showed an early draft to colleagues, their response was that I had left out the arguments of skeptics about climate change, and I accordingly addressed this at length.

SUMMIT STATION, Greenland -- At first glance, this research station on the highest point of Greenland's vast ice sheet doesn't look like much. A scattering of trailers perch on stilts high above the snow, with a neat grid of small yellow tents off to one side. There's a tall metal tower, a few outhouses.

Humans may have been causing climate change for much longer than we’ve been burning fossil fuels . In fact, the agrarian revolution may have started human-induced climate changes long before the industrial revolution began to sully the skies. How? Through the clearing of forests , which still remains the second-largest source of greenhouse gas emissions from human activity.
DUST is all that's needed to plunge the world into an ice age. When blown into the sea, the iron it contains can fertilise plankton growth on a scale large enough to cause global temperatures to drop. The finding adds support to the idea of staving off climate change by simulating the effects of dust - perhaps by sprinkling the oceans with iron filings. Iron-rich dust falling on the ocean has long been known to spark blooms of plankton, and researchers suspect the process could have intensified the ice ages that have occurred over the past few million years.

EXTREME WEATHER: The world will face more risk of natural disasters as a result of ongoing climate change. Image: Flickr/FEMA 17238 Climate change is bringing more droughts, heat waves and powerful rainstorms, shifts that will require governments to change how they cope with natural disasters to protect human lives and the world economy, a new U.N. report says. The 592-page analysis by the Intergovernmental Panel on Climate Change, released yesterday, also makes clear the uneven toll extracted by extreme weather , because its effects can be magnified by a lack of resources to plan for disasters and cope with their aftermath.
For the benefit of anyone who has spent the past decade or so on a different planet, the most frequently asked questions about climate change on this one are as follows. Is it getting warmer? Yes, surface temperatures have risen by 0.8°C from pre-industrial levels.

It's a great time to be depressed about the fate of the planet. The last United Nations confab on climate change, a November meeting in Durban, South Africa, suggested we're unlikely to see any new deal on greenhouse gasses having an impact before 2020. And it was over less than a day before Canada withdrew from what is the only current legally binding treaty on climate change -- the Kyoto Protocol, which expires at the end of this year. The United States never signed up for Kyoto in the first place, of course -- and Barack Obama's administration has hardly been leading the charge for a replacement.
