Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

2009), reproduced from Ramanathan and Feng (2008) Click to enlarge. Cutting HFCs, black carbon, tropospheric ozone, and methane can buy us about 40 years before we approach the dangerous threshold of 2°C warming. HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. Earlier post.)

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

Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. National benefits of the CH 4 plus BC measures versus the reference scenario.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

In general, biofuels made from organic waste are environmentally more benign than those from energy crops. A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. However very few studies include water use impacts.

Here’s How We Could Brighten Clouds to Cool the Earth

Cars That Think

As we confront the enormous challenge of climate change, we should take inspiration from even the most unlikely sources. Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming.
