Urban heat island models may help states meet NOx air standards

Article Abstract:

Researchers at the Department of Energy have used new data from Lear jet flybys over three US cities to refine their computer models simulating the creation of "heat islands" in urban areas. Urban heat buildup increases the rate of photochemical smog formation from nitrogen oxides (NOx), which leads to the formation of ground-level ozone. Environmental Protection Agency (EPA) officials are now assessing the techniques suggested by the models as options for cities to comply with tighter national ambient air quality standards for emissions of NOx.

Climate change meeting skirts decisions on emissions trading

Article Abstract:

The proposal of the European Union to cap emission trading outraged the U.S. and several officials from other countries. The ensuing disagreement among countries may delay any negotiations in the implementation of the Kyoto Protocol.
