Vote for snow

Look, this won’t affect me; I’ll be dead. But if you’re 20-something you really ought to have noticed by now that our snow season is stuffed. By the time you’re my age there won’t be one. No debate, data doesn’t lie:

The main contenders for this election both promise the same grossly inadequate short term emission reductions. Only one offers a mechanism with a chance of working at any sort of adequate level, though there’s miles to go from what they’re proposing. The climate system doesn’t care much about emission rates anyway; it deals in aggregates. And it’s capacity to deal with CO2 is seriously finite. Eventually, that rate needs to be zero or negative. (Around a third of this year’s CO2 increase will still be in the atmosphere in 10,000 years. That is right, 10,000 years*.)

Australians are per capita the worlds worst polluters, and we’re also some of the wealthiest people on the planet. If we can’t lead on this, then who?
