Colorado River Basin including major dams. All reservoirs along the Colorado River might dry up by mid-century as the West warms, according to a new study led by researchers at the University of Colorado, Boulder. Roughly 30 million people now depend on the Colorado River for drinking and irrigation water. Source: AGU.

The authors analyzed measurements from several independent sources—satellites and several types of ground instruments—and found a definitive increase in stratospheric aerosol since 2000. The increase in aerosols since 2000 implies a cooling effect of about 0.1 watts per square meter—enough to offset some of the 0.28

The US Energy Information Administration (EIA) has released a new report, State-Level Energy-Related Carbon Dioxide Emissions, 2000-2010. Factors such as size, population density, available fuels, types of businesses, climate, all play a role in both total and per capita emissions, the EIA noted. Climate Change Emissions'

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. To examine the impacts of climate change on ozone pollution, NCAR scientist Gabriele Pfister and her colleagues looked at two scenarios.

This incongruity provides evidence of human influences on climate change, says Kaufman. Gifford Miller of the University of Colorado, Boulder, a member of the study team. The new study is the first to quantify at a decadal resolution a pervasive cooling across the Arctic from the early part of the first millennium C.E.

Right side: 2008 annual surface air temperature, shown as a departure from the 1971-2000 climatology. Using computer-generated models as well as observations, the team analyzed causes for climate variations in the recent decades. A paper on the study will be published 8 December in the journal Geophysical Research Letters.
