Wind Turbines might actually add to warming

A new paper suggests that wind turbines, installed broadly, might actually change the climate themselves just by disrupting the normal flow of the wind: In a paper published online Feb. 22 in Atmospheric Chemistry and Physics, [the MIT researchers] Wang and Prinn suggest that using wind turbines to meet 10 percent of global energy demand in 2100 could cause temperatures to rise by one degree Celsius in the regions on land where the wind farms are installed, including a smaller increase in areas beyond those regions.

Global Trade’s Dirty Secret: Outsourced Emissions

The Carnegie Institution of Science released a new study this week finding that one-third of the carbon dioxide emissions developed countries release into the atmosphere result from goods and services produced outside their borders. The report’s details are troubling: Carnegie’s researchers estimate that 2.5 tons of CO2 per person are consumed in the United States but are produced elsewhere, and that figure spikes to 4 tons per European. Another point that will cause considerable disagreement among global climate negotiators is Carnegie’s analysis that one-quarter of the emissions in China are actually the result of its exports to its trading partners such as the United States.
