Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor. Sand et al.

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.

Net positive RF (warming) contributions arise from CO 2 , water vapor, NO x , and soot emissions, and from contrail cirrus (consisting of linear contrails and the cirrus cloudiness arising from them). Negative RF (cooling) contributions arise from sulfate aerosol production. Net warming from contrail cirrus is a sum over the day/night cycle.

Researchers in France have found that ozone depletion above Antarctica has significantly reduced the Southern Ocean’s ability to absorb atmospheric CO 2 and has also accelerated acidification of southern polar waters, despite lesser CO 2 uptake. The results revealed that, between 1987 and 2004, around 2.3 Lenton, A., Tagliabue, and J.

However, this approach neglects non-CO 2 combustion emissions and effects, namely, soot and sulfate aerosols, water vapor, and NO x. In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming.

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.

The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) Methane is more than 20 times as effective as CO 2 at trapping heat in the atmosphere—i.e., a global warming potential of 21. of total CH 4 emissions (103.0 Tg CO 2 eq.) Tg CO 2 Eq.,
