Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

Projected changes in summer mean usable capacity of power plants in the US and Europe for the SRES A2 emissions scenario for the 2040s (2031–2060) relative to the control period (1971–2000). A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., Source: van Vliet et al. Click to enlarge.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

The report’s best estimate of direct climate influence by black carbon is about a factor of two higher than most previous work. This includes the estimates in the 2007 Intergovernmental Panel on Climate Change (IPCC) Assessment, which were based on the best available evidence and analysis at that time.

Researchers present new explanation for the long-range transport of PAH pollutants

Green Car Congress

When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).

EPA Issues Proposed Endangerment Finding for Greenhouse Gases; Proposed Cause or Contribute Finding Identifies Motor Vehicles as Contributing Source

Green Car Congress

The proposed cause or contribute finding concludes that that the combined emissions of CO 2 , CH 4 , N 2 O, and HFCs from new motor vehicles and motor vehicle engines contribute to the atmospheric concentrations of these key greenhouse gases and hence to the threat of climate change.

EPA issues greenhouse gas proposals

Green Cars News

It has been deemed by the EPA that the emissions from new motor vehicles and their engines contribute to these concentrations and threaten climate change. The analysis also looked at the impact of climate change on human health and suggests that it may lead to higher levels of ground-level ozone, a harmful pollutant.
