USA | Climate | Birch Forest
Birch forest in the Acadia National Park in Maine. Cool, moist climate has been the norm on the North Atlantic Coast, but that is changing with the ongoing global warming. With current level of heat trapping emissions, the temperature in the area is likely to rise by more than 5 degrees Fahrenheit by 2070 compared to 1990 levels. That means drier climate and disrupted eco systems.
With warmer climate, birch forests in the northern hemisphere are expanding. Forest expansion has been seen as good news, as the trees are important for sequestering of CO2. However; the new vegetation in what used to be treeless areas reduce the reflection of sunlight (albedo effect). Even though the new forest absorb CO2, the net result is still a warming of the climate. Head over to www.sciencenordic.com if you want to read more on the subject.
