Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

The result implies that globally, cloud changes caused by particles from all forms of industrial pollution block 1 Watt of solar energy per square meter of Earth’s surface, masking almost a third of the present-day warming from greenhouse gases.

Potent GHG SF6 rapidly accumulating in atmosphere, driven by demand for SF6-insulated switchgear in developing countries

Green Car Congress

Of all the greenhouse gases regulated under the Kyoto Protocol, SF 6 is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon. Peter Simmonds at the University of Bristol, UK, and his colleagues calculated annual emissions of SF 6 between 1978 and 2018. Simmonds et al. —Simmonds et al.

California ARB mods to ZEV regulations for IVMs would result in ~1.9% drop in total ZEV/TZEV units 2018-2025; no impact on air quality requirements

Green Car Congress

The initial sales requirement was 2% of car sales in 1998 (representing about 20,000 vehicles at the time), increasing to 5% in 2001 and 10% in 2003. The 2012 amendments to the ZEV reg adopted as part of the ACC package reduced the California sales upper bound for IVMs from 60,000 units to 20,000 per year beginning with the 2018 model year.

Studying Climate Change with an Ice Radar Drone

Cars That Think

These great masses store enough water to raise global sea level by 65 meters should they melt entirely. Although neither ice sheet is expected to melt completely anytime soon, their incredible scale makes even small changes consequential for the future of our planet.
