Co-benefits from improved air quality can offset some if not all of the near-term costs of carbon-reduction policies. If the US commits to buying a carbon policy, citizens will also get reduced air pollution and improved health for free. More »
A series of studies demonstrates why people use trends in local weather and temperature, rather than statistically relevant global climate patterns, to construct their beliefs about climate change. More »
A recent study demonstrates that black carbon may be the second most significant driver of anthropogenic climate change. More »
Cap-and-tax might be the best way to mitigate emissions after all. More »
