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.,

Argonne researcher using hydrous ethanol as a dual fuel to lighten the carbon footprint of locomotives

Green Car Congress

Hydrous ethanol (also sometimes known as azeotropic ethanol) typically ranges from 186 proof (93% ethanol, 7% water) to 192 proof (96% ethanol, 4% water). Earlier post.). It’s a good, fast way to adapt technology into an existing engine by manufacturing a retrofit kit that can be installed on current engines or on newer engines.

Using Ozone-Generated Bubbles to Remove Oil Sheen and Contaminants from Water

Green Car Congress

A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Water from mining of oil sands and oil shale. Heavy metals in soil.

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.

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

Green Car Congress

Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said. Click to enlarge. °C (within a likely range of 0.2-0.7

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: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

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). Seen together, the climate impact of these two factors is bigger than that of the sector’s carbon emissions.
