The Ozone Layer's Unwelcome Return?

Science Daily News. (12 Junio 2008).

The recovery of the ozone layer is considered essential for the health of the planet's living creatures, but new research suggests it could also assist in the fight against global warming. In the 13 June issue of Sciese, climatologists report that ozone recovery could restore wind patterns in the Southern Hemisphere that have blown out of kilter due to ozone depletion and the buildup of greenhouse gases...

Climate change: Cool ozone

Nature (01 Feb 2008).

The influence of global warming on temperature trends at higher altitudes has been hotly debated. Stratospheric ozone depletion is another piece in the remaining tropical climate puzzle...

Antarctic ice threatened by ozone-hole recovery

Nature (29 April 2008).

Recovery of the ozone hole above Antarctica could warm the Antarctic and cause more ice to melt in coming decades, researchers say. As the ozone hole heals, wind patterns that shield the interior of the polar region from warm air may break down, causing warming in the Antarctica as well as warmer and drier conditions in Australia...

Climate Models Overheat Antarctica, New Study Finds.

ScienceDaily (May 8, 2008).

Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise...

Stratospheric Injections To Counter Global Warming Could Damage Ozone Layer

ScienceDaily (Apr. 25, 2008).

A much-discussed idea to offset global warming by injecting sulfate particles into the stratosphere would have a drastic impact on Earth's protective ozone layer, new research concludes. The study, led by Simone Tilmes of the National Center for Atmospheric Research (NCAR), warns that such an approach might delay the recovery of the Antarctic ozone hole by decades and cause significant ozone loss over the Arctic...

Excessive Reactive Nitrogen in Environment Alarms Environmental Scientists

ScienceDaily (May 18, 2008).

While human-caused global climate change has long been a concern for environmental scientists and is a well-known public policy issue, the problem of excessive reactive nitrogen in the environment is little-known beyond a growing circle of environmental scientists who study how the element cycles through the environment and negatively alters local and global ecosystems and potentially harms human health...
