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.

MIT report finds China’s actions on climate change crucial; argues for global economy-wide greenhouse gas tax

Green Car Congress

A new report from the MIT Joint Program on the Science and Policy of Global Change shows the importance of all major nations taking part in global efforts to reduce emissions—and in particular, finds China’s role to be crucial. From 2000 to 2010, China’s energy use grew 130%, up from a growth of 50% the previous decade.

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

Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Emission rates of BC in the year 2000 by region, indicating major source categories in each region. Black carbon aerosol plays a unique and important role in Earth’s climate system. Source: Bond et al.

Study associates long-term exposure to air pollution with increasing emphysema

Green Car Congress

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. This work in the MESA Air study was led at the University of Washington.

Study finds global carbon emissions reached 10 billion tonnes in 2010

Green Car Congress

Published in the journal Nature Climate Change , the new analysis shows fossil fuel emissions increased by 5.9% each year between 2000 and 2010—three times the rate of increase during the 1990s. Nature Climate Change doi: 10.1038/nclimate1332. On average, fossil fuel emissions have risen by 3.1%

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). The 75 ppb level over eight hours is the threshold that is considered unhealthy by the Environmental Protection Agency.

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University.
