Energy Smart

Al Gore likes to quote Winston Churchill that we “are entering a time of consequences” as a rallying call to action.  Well, Gore probably agrees, we are not entering … we are in.  And, well, global weather patterns are providing a reminder as are lead scientists.

Jim Hansen has a new article out which concludes:

The global community must aim to restrict any further global warming to less than 1 °C above the temperature in 2000. This implies a CO2 limit of about 450 parts per million or less. Such scenarios require almost immediate changes to get energy and greenhouse gas emissions onto a fundamentally different path.

We don’t have time. Action must begin. And begin seriously if we are to avoid crossing this threshhold.
