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 All 14 would curb the release of either black carbon or methane.

Fast action on black carbon, ozone and methane could help limit global temperature rise to 2 degrees C

Green Car Congress

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)—and The climate change benefit is estimated for a given year (2050) and human health and crop benefits are.

UN report projects that increasing use of HFCs likely to have a significant climate impact by 2050; equivalent to current total annual emissions from transport

Green Car Congress

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). Climate and the Ozone Layer. Source: UNEP. Click to enlarge.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Eventually, they’ll add equipment to spray tiny aerosol particles of calcium carbonate, the compound found in limestone, blackboard chalk, and Tums antacids.

UN Review of Recent Climate Research Concludes That Impacts Of Climate Change Coming Faster Than Anticipated

Green Car Congress

Ocean acidification caused by the absorption of carbon dioxide in seawater is already increasing along the California coast decades earlier than existing models predict. The growth in carbon dioxide emissions from energy and industry has exceeded even the most fossil-fuel intensive scenario developed by the IPCC at the end of the 1990s.

Climate Expert: Don't Call It Geoengineering

Cars That Think

Spectrum : When you talk about climate interventions, are you including carbon removal and sequestration in that category? We do some work on carbon removal, but that's pretty big space with a lot of investment. Wanser: We do include that in the broad category. Which is good. What do we have to offer these billion people?

ICCT report finds global implementation of advanced emissions and fuel-quality regs could cut early deaths from vehicle emissions by 75% in 2030

Green Car Congress

A study by a team at the the International Council on Clean Transportation (ICCT) finds that if that lag persists and present trends in vehicle activity continue, early deaths from vehicle-related PM 2.5 GtCO 2 e (applying GWP-100 metric) cumulatively from 2015 to 2030, 95% of which would come from reductions in black carbon.
