Darkest blue areas represent regions of maximum ozone depletion

2004


Increase of atmospheric carbon dioxide

2000-about

365 ppm

Carbon dioxide levels have risen by 30% in the last 200 years.

The IPCC projects that, if unchecked, atmospheric carbon dioxide concentrations

will range from 650 to 970 ppm by 2100.


Movement of transboundary pollutants

A large dust storm developed in East Asia on 6-7 April 2001, moving over Russia, Japan, the Pacific Ocean, Canada, and ultimately over the United States on 17 April 2001


Air pollution due to wild fires

Wild fires in Africa are a major source of air pollution

Tens of thousands of fires are detected every year


Retreating Gangotri glacier

Receding glacier tracked since 1780

In the last 25 years, Gangotri Glacier has retreated more

than 850m

(2 788 ft)
