Pinatubo eruption tests arctic circulation's impact on climate
A recent NASA-funded study has linked the 1991 eruption of the Mount Pinatubo to a strengthening of a climate pattern called the Arctic Oscillation. For two years following the volcanic eruption, the Arctic Oscillation caused winter warming over land areas in the high and middle latitudes of the Northern Hemisphere, despite a cooling effect from volcanic particles that blocked sunlight.

The Arctic oscillation: A key to this winter's cold--and a warmer planet
Why has the Arctic warmed so dramatically in recent years? How does the Arctic's circulation keep frigid air over the poles and sometimes allow it to spill across the United States? And how might global change affect the behavior of this circulation? Clara Deser, from the National Center for Atmospheric Research, will address these and other questions in a presentation at the annual meeting of the American Association for the Advancement of Science.

AGU journals highlights - 11 February 2003
Icebergs may have caused a dip in the North Atlantic Oscillation. Combining warm and cool Pacific waters may forestall El Nino. Arctic ozone loss may be caused by a sunlight-induced chemical breakdown. Methane in the Martian atmosphere might indicate presence of subsurface life. Efforts to control particulate matter air pollution may have the unintended consequence of increasing surface ozone. Meteorites crashing into Jupiter's moon Europa have likely triggered changes in its chemistry. And much more.... (2003-02-11)

Control of methane emissions would reduce both global warming and air pollution, researchers find
Both air pollution and global warming could be reduced by controlling emissions of methane gas, according to a new study. The reason, researchers say, is that methane is directly linked to the production of ozone in the troposphere. Ozone is the primary constituent of smog and both methane and ozone are significant greenhouse gases. Mitigation should therefore be considered on a global scale and must take into account a rising global background level of ozone. (2002-10-09)
