NOVEMBER 29, 2010

Led by the tiny Pacific island of the Federated States of Micronesia, a growing group of low-lying islands and other vulnerable countries are calling for fast action on the approximately 50% of global warming that is caused by pollutants other than carbon dioxide (CO 2 ). The next round of UN climate negotiations begins in Cancun today.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Controlling soot from fossil fuels and solid biofuels may be a faster method of reducing Arctic ice loss and global warming than other options, including controlling CH 4 or CO 2 , although all controls are needed, according to a new study by Dr. Mark Z. He also found that soot emissions kill more than 1.5 Mark Jacobson.

European Parliament calls for fast action to cut non-CO2 climate forcers

SEPTEMBER 15, 2011

The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Even cutting CO 2 emissions to zero today will not produce cooling for a thousand years.
