The Economics of 350Volume 1: Issue 5: Oct 22, 2010
Stopping global warming and protecting the Earth’s climate is a daunting challenge. To avert a crisis, we must develop petroleum-free transportation, dramatically change how we create and use energy, and much more. These changes carry a cost, and especially in difficult times there is strong resistance to spending very much at all to protect the planet. Many think moving too aggressively could lead to economic disaster. Some economists advocate only slow, gradual responses to climate change, lest the costs of mitigation become too large.
The physical science of the atmosphere is not determined by cautious economists, however. The more CO2, the hotter the world will get, the faster sea level will rise, and the more erratic our weather patterns will become. Doubling the amount of CO2 that was in the air before the Industrial Revolution—from 280 parts per million (ppm) in 1750 up to 560 ppm, a milestone we will reach in a matter of decades under business as usual—could raise the average global temperature by 3 °C (5.4 °F); newer studies actually project increases of up to 6 °C (11 °F).
To protect our planet, we propose setting a target of 350 ppm and taking prompt, decisive action to enable us to attain that goal.
