Net warming from NO x emissions is a sum over warming (short-term ozone increase) and cooling (decreases in methane and stratospheric water vapor, and a long-term decrease in ozone) terms. Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions.

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.

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. billion tons of carbon was not taken up by the oceans.

The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Because these climate forcers are short-lived, reducing them produces a fast climate response.

Led by the tiny Pacific island of the Federated States of Micronesia, a growing group of low-lying islands and other vulnerable countries are calling for fast action on the approximately 50% of global warming that is caused by pollutants other than carbon dioxide (CO 2 ). million lives lost each year due to black carbon soot.

R134a replaced CFC-12 as the MAC refrigerant in the early 1990s due to the negative impact of CFCs on the Earth’s ozone layer. HFC-152a, HFO-1234yf, and carbon dioxide are alternatives that may substantially reduce climate impacts and meet safety standards.A transition to a new refrigerant is not easy.
