NASA says Canada in 'hot spot' of ecological change

A new NASA study predicts massive ecological changes for Canada's Prairies and boreal regions by the year 2100. Those areas are in "hot spots" highly vulnerable to massive environmental changes this century due to global warming, the study states.
(NASA climate scientist Duane) Walliser said that all across the globe, whole ecological zones such as deserts and tundra will be on the move because of "unprecedented" warming at a pace faster than at any time in 10,000 years.
The NASA study says 37 per cent of Earth's land surface will transform from one major ecosystem zone, or biome, into another, while 49 per cent of land surfaces will see at least some changes in plant species.
(NASA collaborator, Jon) Bergengren (a global ecologist and earth systems scientist) said some wildlife will not survive these transformations. Obviously, it is much easier for plants and animals to migrate or adapt to this level of climatic change over 10,000 years than it is over 100 years, he said.
