survive frosty winters. So the biota will face many shocks before the climate stabilizes.Warming is also a major problem for marshes and the permafrost, which will release accumulated methane and carbon dioxide gas. Gas hydrates from the northern sea shelf will vaporize. All that will drastically increase atmospheric greenhouse gas concentrations, spurring the warming on in a vicious circle.
The environmental balance has already been upset. Many plants and animals will suffer. In particular, the polar bear's habitat is doomed to shrink, and millions of wild geese, eiders, brants and other birds will lose half of their nesting grounds in a matter of 20-40 years. A three to four degree warming may interrupt the food chain of the tundra ecosystem, lead to the extinction of many species.
