If we don't look maybe it will go away.





Climate warming gases rising faster than expected

Carbon emissions have been growing at 3.5% per year since 2000, up sharply from the 0.9% per year in the 1990s, Christopher Field of the Carnegie Institution for Science told the annual meeting of the American Association for the Advancement of Science.

"It is now outside the entire envelope of possibilities" considered in the 2007 report of the International Panel on Climate Change, he said. The IPCC and former vice president Al Gore received the Nobel Prize for drawing attention to the dangers of climate change.


Mass migrations and war: Dire climate scenario

If we don't deal with climate change decisively, "what we're talking about then is extended world war," the eminent economist said.

His audience Saturday, small and elite, had been stranded here by bad weather and were talking climate. They couldn't do much about the one, but the other was squarely in their hands. And so, Lord Nicholas Stern was telling them, was the potential for mass migrations setting off mass conflict.

"Somehow we have to explain to people just how worrying that is," the British economic thinker said.


Climate change: 'Feedback' triggers could amplify peril

CO2 and methane account for the lion's share of the gases that have driven global temperatures inexorably higher over the last century.

Nitrous oxide, or N2O, is far less plentiful in volume, but 300 times more potent as a greenhouse gas than CO2. It accounts for about six percent of total global warming, mainly due to a shift toward chemical-intensive agriculture.

In experiments near the Russian city of Vorkuta, Pertti Martikainen of the University of Kuopio in Finland and colleagues found that N2O leaked as a result of cryoturbation, a process that occurs when frozen soil is thawed and then refreezes.

So much good news lately, I just can't stand it.

Where's Terrance McKenna when you need him?

My word verification for this post was "terds", and I swear that's true.
I have to ponder the implications.
