Roof of the world melting away?

Stop climate change

The world's leaders meet at the end of 2009 in Copenhagen to determine the fate of the climate. They could set us on the path to a deep emissions cuts or they could lock the planet into catastrophic, irreversible climate change.

Impacts

No one knows how much warming is "safe". What we do know is that climate change is already harming people and ecosystems. Its reality can be seen in melting glaciers, disintegrating polar ice, thawing permafrost, dying coral reefs, rising sea levels, changing ecosystems and fatal heat waves. And it is not only scientists that are witnessing these changes. From Inuit in the far north to islanders near the equator - people are already struggling with the impacts of climate change.

Global Melting

As the Earth warms, its ice melts. This global melting is an early and obvious sign of climate change, but its implications go far beyond merely losing snow and ice. For starters, some people and ecosystems depend on the ice - glaciers for water supply in areas of seasonal rainfall, for example, and sea ice for habitat.

Glaciers

Glaciers are more than just magnificent landscapes of ice and snow. Around the world they act as frozen reservoirs providing water for billions of people, as well as animals and plants. Glaciers also influence local climates and ecosystems, and their melting is a dramatic warning of a warming world.

Habitat loss

"Most of the world's endangered species -- some 25 percent of mammals and 12 percent of birds -- may become extinct over the next few decades as warmer conditions alter the forests, wetlands, and rangelands they depend on, and human development blocks them from migrating elsewhere." -- UN Framework Convention on Climate Change.

Health, food and water

Heat waves attributable in part to climate change are forecast to kill hundreds of thousands in this century, however climate change will also have disastrous effects on water supplies, agriculture, and the spread of disease. Rich and poor alike will be affected, but countries that are already struggling to provide food and water for their people will suffer the most.
