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.)

While the existence of higher CO 2 levels overs cities—CO 2 domes—has been known for more than a decade, their effects on local air pollution has up to now not been explored. Although the health impacts of such changes are uncertain, he notes, they are of concern. Jacobson (2010) Enhancement of Local Air Pollution by Urban CO 2 Domes.

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.

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways. Excess runoff can also contribute to flooding.

As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. Shindell et al.
