Greening of the Arctic
GreeningClimate change is impacting terrestrial Arctic ecosystems, with evidence showing that Arctic vegetation has undergone significant shifts in recent decades. There is an increase in productivity over much of the Arctic, as well as an increase in the length of the growing season. The northward movement of the treeline is encroaching on the southern margin of the tundra and could result in significant losses of tundra habitat by 2100. Climate warming is also likely to change the composition of plant communities. While the number of plant species inhabiting the Arctic may actually increase over the long term, the diversity of plants unique to the Arctic will probably decrease in abundance.
