International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C °F) by 2050, as well as improving human health and agriculture.

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

Green Car Congress

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.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. Ramanathan and Victor highlight the importance of aggressively reducing CO 2 emissions, but note that the road ahead will be long, difficult, and expensive, and that “in the meantime, a fast-action plan is needed.”

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

Green Car Congress

The founding coalition partners are Bangladesh, Canada, Ghana, Mexico, Sweden, and the United States, together with the UN Environment Programme (UNEP). This may be the only way to reduce climate impacts in the near term, and is a critical complement to the primary battle to reduce emissions of CO 2. Earlier post.). Earlier post.).
