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.

Study finds global rivers and streams emitting 3x IPCC estimates of the GHG N2O

Green Car Congress

That’s three times the amount estimated by the Intergovernmental Panel on Climate Change (IPCC). Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. The findings, the authors hope, will lead to more effective mitigation strategies.

CSIRO publishes Southern Hemisphere GHG data online

Green Car Congress

For the first time, observed Southern Hemisphere greenhouse gas (GHG) data can be easily accessed by the public on a new CSIRO website. The atmospheric level of carbon dioxide, which is the most important long-lived greenhouse gas influenced by human activities, is at its highest level in more than a million years. per cent each year.

EPA releases national assessment of strategies to reduce air pollution at ports

Green Car Congress

Implementing these approaches, the report finds, would reduce greenhouse gas and other harmful emissions from diesel-powered ships, trucks and other port equipment. Many ports and related freight corridors and facilities are located in nonattainment or maintenance areas for EPA’s ozone and PM 2.5 Click to enlarge.
