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

Green Car Congress

Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming. Jacobson found that the combination of the two types of soot is the second-leading cause of global warming after carbon dioxide. Black carbon converts sunlight to heat and radiates it back to the air around it.

New international Climate and Clean Air Coalition to focus on reduction of short-lived climate pollutants

Green Car Congress

The coalition will focus efforts on reducing black carbon, hydrofluorocarbons (HFCs), and methane. Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near-term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F), Earlier post.).

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

In particular, the study led by Drew Shindell found that methane emissions have a larger warming impact due to those interactions than accounted for in current carbon-trading schemes or in the Kyoto Protocol. And hydroxyls drive long chains of reactions involving other common gases, including ozone. Shindell et al.

North American Countries Target “Super” Greenhouse Gases Through Strengthened Ozone Treaty

Green Car Congress

The US, Canada, and Mexico have submitted a proposal to strengthen climate protection under the Montreal Protocol— the international treaty that phases out the production of a number of substances responsible for ozone depletion. Uncontrolled growth of HFCs will offset the benefits of reducing carbon dioxide. Source: IGSD.

ARB releases proposed cap-and-trade regulation for comment; transportation fuels impacted in 2015

Green Car Congress

The cap is enforced by requiring each source that operates under the cap to turn in one allowance or offset credit for every metric ton of carbon dioxide equivalent (MTCO 2 e) that it emits. The cap-and-trade program gives sources flexibility to make the most cost-effective choices about when and how to reduce emissions.
