Dan Kammen emphasized various options we face in confronting risks associated with climate change which were looked at in a recent MIT study. In a talk at the West Coast Green Conference he pointed out that after policy changes positively affecting the solar industry were made in 2007, the industry quadrupled in 2008 . So balancing policy, economy, human behavior, and the fact that the world is heating up due in no small part to carbon dioxide emissions, we're able to see that yes, we still have a shot at not cooking the planet if we act now.
“We still have a 50-50 chance of not frying ourselves: MIT study says”
