Ozone hole grows in 2008

The ozone hole over Antarctica in 2008 is larger in both size and ozone loss than last year, but not as large as in 2006, the European Space Agency said Tuesday
The hole is a thinning area in the ozone layer over Antarctica and the size of the hole varies every year depending on weather conditions.
This year, the size of the thinned area reached about 27 million square kilometers (10.4 million square miles), compared to 25 million square kilometers (9.65 million square miles) in 2007.
In 2006, the hole was a record 29 million square kilometers (11.2 million square miles), larger than North America, the ESA said.
