Which among the following ecosystems are likely to face the impact of global warming more than the others?
The ecosystems that are most likely to be affected by global warming are those in the higher latitudes i.e. the tundra forests. The Polar Regions will feel the impact of warming more than the others. Species that live in the higher alpine zones, would be forced to move higher up to find a suitable habitat, thus, reducing the area in which they can live. If the rate of climate change continues to accelerate, then the extinction of some mountain plants and animals is certain.
