Low Temperatures Enhance Ozone Degradation above the Arctic
Extraordinarily cold temperatures in the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far: The mechanisms leading to the first ozone hole above the North Pole were studied by scientists of the KIT Institute of Meteorology and Climate Research (IMK).

NOAA, NASA: Significant ozone hole remains over Antarctica
The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on September 12, stretching 10.05 million square miles, the ninth largest on record. Above the South Pole, the ozone hole reached its deepest point of the season on October 9 when total ozone readings dropped to 102 Dobson units, tied for the 10th lowest in the 26-year record.

Unprecedented Arctic ozone loss occurred last winter
A NASA-led study has documented an unprecedented depletion of the Earth's protective ozone layer above the Arctic last winter and spring that was caused by an unusually prolonged period of extremely low temperatures in the stratosphere. (2011-10-03)

Southern South American wildfires expected to increase, says CU-Boulder study
A new University of Colorado Boulder study indicates a major climate oscillation in the Southern Hemisphere that is expected to intensify in the coming decades will likely cause increased wildfire activity in the southern half of South America. (2011-08-23)

Columbia engineering study links ozone hole to climate change all the way to the equator
In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University's School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation of the Southern Hemisphere all the way to the equator.

Record depletion of Arctic ozone layer caused increased UV radiation in Scandinavia
Over the past few days ozone-depleted air masses extended from the north pole to southern Scandinavia leading to higher than normal levels of ultraviolet (UV) radiation during sunny days in southern Finland. (2011-04-06)

Human impacts on the marine ecosystems of Antarctica
A team of scientists in the United Kingdom and the United States has warned that the native fauna and unique ecology of the Southern Ocean, the vast body of water that surrounds the Antarctic continent, is under threat from human activity. (2011-04-01)

Carbon sink at South Pole has grown recently, historical collections reveal
By studying collections of a marine bryozoan that date back to a famous 1901 expedition to the South Pole, researchers have found that those organisms were growing steadily up until 1990, when their growth more than doubled. (2011-02-22)

Surprise Hidden in Titan's Smog: Cirrus-Like Clouds
Every day is a bad-air day on Saturn's largest moon, Titan. Blanketed by haze far worse than any smog belched out in Los Angeles, Beijing or even Sherlock Holmes's London, the moon looks like a dirty orange ball. (2011-02-04)

Using chaos to model geophysical phenomena
Geophysical phenomena such as the dynamics of the atmosphere and ocean circulation are typically modeled mathematically by tracking the motion of air or water particles. (2010-12-07)
