News broke earlier today that the EPA was getting ready to make its long awaited announcement—that carbon dioxide is a threat to human health. Well, the moment has come, and now it's official: the EPA has found that CO2 and six other greenhouse gases contribute to air pollution that may endanger public health and welfare. This is huge news—it will completely revolutionize the way the US views carbon emissions, and it opens the door for the government to take action against greenhouse gases. And it's perhaps the biggest victory in the fight against climate change in US politics yet.
