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. Ground-level ozone is mostly produced when ultraviolet light reacts with pollutants from fossil fuels.

the distribution of black carbon in the atmosphere and determine its role in the climate system. Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact.

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.

Study Finds Damage, Pollution from Western Wildfires Could Surge With Moderate Global Warming

Green Car Congress

By 2055, wildfires in the western United States could scorch about 50% more land than they do now, causing a sharp decline in the region’s air quality, according to a new study by atmospheric researchers at Harvard. The increase is due mainly to the simulated rise in wildfire frequency in the future, warmer climate.

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 RCPs were chosen to represent a broad range of climate outcomes, based on a literature review. The RCP 8.5

An analysis by Deutsche Bank Climate Advisors, however, suggests that production of 1.1 Automobiles are major contributors to air pollution and greenhouse gas emissions. The top four producers of light vehicles—China, the United States, Japan, and Germany—together account for more than half of global output.
