UCL-led study finds climate impact caused by growing space industry needs urgent mitigation

Green Car Congress

The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. The space industry is one of the world’s fastest growing sectors.

CSIRO study finds ozone uptake in oceans much lower than previously thought

Green Car Congress

CSIRO scientists have developed a new way to account for ozone in computer simulations of the climate. This latest modeling shows that the oceans take much less ozone out of the atmosphere than previously thought. Ozone (O 3 ) is formed by reactions of chemicals such as nitrogen oxides and volatile organic compounds—i.e.,

UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

Global benefits from full implementation of the identified measures in 2030 compared to the reference scenario. Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. The identified measures complement, but do not replace, anticipated carbon dioxide reduction measures.

Researchers Find That Stratospheric Ozone Depletion Reduces Southern Ocean Carbon Uptake

Green Car Congress

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.

Study Finds Ozone, Nitrogen Change the Way Rising CO2 Affects Earths Water

Green Car Congress

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.

US, China, and G-20 agree to work to global phase down of HFCs

Green Car Congress

While they do not deplete the ozone layer, many are highly potent greenhouse gases whose use is growing rapidly as replacements for ozone-depleting substances being phased out under the Montreal Protocol. Left unabated, HFC emissions could grow to nearly 20% of carbon dioxide emissions by 2050, a serious climate mitigation concern.

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

This study will measure concentrations of non-tailpipe (NTP) particulate matter across Toronto, Canada to determine how much non-tailpipe pollution people might breathe in everyday life and how to better measure these exposures in the future. Establish a bio-bank of samples to support future HEI-sponsored research in this area.
