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.

EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

Green Car Congress

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

NO x is a precursor for both ground level ozone and secondary PM 2.5 which are regulated under the National Ambient Air Quality Standards (NAAQS) because of their adverse effects on human health and the environment.

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

Green Car Congress

This is especially the case for those draining nitrogen-enriched urbanized and agricultural watersheds, highlighting the importance of managing nitrogen before it reaches open water. Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction.

National Research Council report finds it unlikely the US will meet cellulosic biofuel mandates absent major innovation or a change in policies

Green Car Congress

Given the numerous barriers outlined.the committee judges that the consumption mandate for cellulosic biofuels is not likely to be met by 2022 without substantial improvement in technologies in the next few years and a stable economic and policy environment to encourage accelerated demonstration and deployment of cellulosic biofuels.

Climate Expert: Don't Call It Geoengineering

Cars That Think

We see it as similar to the ozone hole problem, where we really needed a tight, science-based focus on the limits to human inputs to the system--and howthose inputs affected the ozone layer's ability to keep people safe. What do we have to offer these billion people?

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

The SCOPE (Scientific Committee on Problems of the Environment) International Biofuels Project, has published the full proceedings of its Rapid Assessment workshop on the environmental effects of biofuel technologies, 22-25 September 2008. However very few studies include water use impacts. Ravindranath et al. Simpson et al.
