MIT researchers build model simulating atmospheric transport of PAHs; how chemicals get to the Arctic

Green Car Congress

Selin and Friedman use the global 3-D chemical transport model GEOS-Chem to track the day-to-day transport of PAHs—toxic byproducts of burning wood, coal, oil and other forms of energy that remain in the atmosphere for less time than other persistent organic pollutants regulated by global standards.

Measurements of CO2 and CO in China’s Air Indicate Sharply Improved Combustion Efficiency

Green Car Congress

The findings, published in the 21 September issue of Atmospheric Chemistry and Physics , are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climate change.

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

Green Car Congress

These gases come from human activities such as combustion of coal and oil as well as natural sources such as emissions from plants. Warmer temperatures and other changes in the atmosphere related to a changing climate, including higher atmospheric levels of methane, spur the chemical reactions that lead to ozone.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. Anthropogenic climate change confronts humanity with a challenge: How can we keep warm now as we try to prevent our world from overheating in the future?
