Columbia team organizes available scientific evidence on the effects of air pollution on children’s health

Green Car Congress

Researchers at Columbia University, with colleagues at Boston University and Abt Associates, have identified concentration-response (C-R) functions for a number of adverse health outcomes in children associated with air pollutants largely from fossil fuel combustion.

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.

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 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.

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). Ozone pollution also damages crops and other plants. Scenario A2 and RCP 8.5. Ozone formation.

Study finds that worldwide SO2 emissions rose between 2000-2005 after decade of decline; China, shipping topped growth

Green Car Congress

Global sulfur dioxide (SO 2 ) emissions peaked in the early 1970s and decreased until 2000, with an increase in recent years due to increased emissions in China, international shipping, and developing countries in general, according to a new analysis appearing in the open access journal Atmospheric Chemistry and Physics.

Radiative forcing due to perpetual constant year 2000 emissions grouped by sector for 2020 (left) and 2100 (right) showing the contribution from each species. Cars, buses, and trucks release pollutants and greenhouse gases that promote warming, while emitting few aerosols that counteract it. From Unger et al., Click to enlarge.
