Winter is still nine weeks away.

Most preschoolers understand that you need sunshine to warm things up. When the sun sets, it gets cold. If the sun set for 4-6 months, it would get really cold. But not John Holdren.

This seems like a fairly obvious question, but a few readers are having a tough time with it. Ice forms when the air and water are cold. In the case of salt water ice, the water has to be cold down to a depth of several tens of metres before ice starts to form on the surface.
Marc Morano reminded me of an E-mail exchange which Susan Solomon had four years ago with Rachel Garthwaite of the Royal Society, as reported by Bishop Hill.
The accuracy of climate models is simply astonishing!
Assuming that greenhouse gas emissions rise rapidly in the future, the frequency of Arctic hurricanes could fall from an average of 36 per winter to about 17 by 2100, the model suggests. If emissions rise more slowly the number of hurricanes could fall to 23 per winter.

If I were betting, I’d put my money on 36 …..
Arctic sea ice retreat, increases in heavy rainfall and flooding, permafrost melt, loss of glaciers and snowpack with attendant changes in water supply, increased intensity of hurricanes, etc.
OMG
climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop.

Democrats are three times more likely to be victims of global warming than Republicans, and twice as likely as Independents.

If current trends continue, the Republican party will be fully emancipated by the year 2020. Democrats seem to be stuck in a bit of a rut.

Tasmania’s Climate Change Minister believes climate change predictions for the state could bring new economic opportunities.

“I think there are opportunities in context of national scenarios and international scenarios so we’ve got to look at these opportunities in terms of how processes and industry might be developing on the mainland,”

The EPA photo above correctly identifies man made emissions of Earth’s most important greenhouse gas. The only problem is that they don’t know which gas it is.
A couple of weeks ago, CO2 worriers were ready to pack it in and escape to a “habitable planet” only twenty light years away.
These seemed like a brilliant way to raise the IQ of Earth, but sadly it turns out their Mecca probably doesn’t exist.
