Cutting HFCs, black carbon, tropospheric ozone, and methane can buy us about 40 years before we approach the dangerous threshold of 2°C warming. —co-author HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. Black Carbon. From Molina et al. Earlier post.) Earlier post.).

Global average values for the year 2000. The researchers used a suite of climate chemistry models to consider the climate effects of all long- and short-lived gases, aerosols and cloud effects, not just carbon dioxide, resulting from transport worldwide. Car travel emits more carbon dioxide than air travel per passenger mile.

SLCPs include black carbon (soot), methane and hydrofluorocarbons (HFCs)—the fastest-growing source of GHG emissions in California and globally—which are used as refrigerants, aerosol propellants and insulation. Black carbon. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change.

In addition to CO 2 , other compounds such as ozone (O 3 ) precursors (nitrogen oxides (NO x =NO+NO 2 ), carbon monoxide (CO), and volatile organic compounds (VOCs)) and aerosols such as black carbon (BC) and organic carbon (OC) are emitted by ships. Of that, international shipping accounts for 83% (870 TgCO 2 yr ?1

In particular, the study led by Drew Shindell found that methane emissions have a larger warming impact due to those interactions than accounted for in current carbon-trading schemes or in the Kyoto Protocol. And hydroxyls drive long chains of reactions involving other common gases, including ozone. —Drew Shindell.

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.

Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. Fourteen production aircraft were manufactured, but one was scrapped in 1994 and another crashed in 2000.).

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion.

CH 3 I production from cellulosic feedstocks using a microbial co-culture. As end products, methyl halides (CH 3 X, X = Cl, Br or I) are used in a variety of applications. They can also be used as intermediates for the chemical synthesis of more complex carbon compounds such as fuel hydrocarbons. Adapted from Bayer et al.
