It's Still Cold

Environment Canada says it's -18 degrees C, -29 w/windchill. Better, but not much. But here's some good news on a still-frigid Tuesday: global warming is irreversible.

From discovery.com:

"The study's authors said there was "no going back" after the report showed that changes in surface temperature, rainfall and sea level are "largely irreversible for more than 1,000 years after CO2 emissions are completely stopped."

So should we quit all this green-gab and just pack it in? Not so fast, says the study's lead author, Susan Solomon of the National Oceanic and Atmospheric Association in the Telegraph:

"Climate change is slow, but it is unstoppable - all the more reason to act quickly, so the long-term situation does not get even worse."

Hooray?
