Europe's forests, once largely destroyed to be used for timber and farmland, have finally began to make a notable comeback after decades of closely-monitored growth. However, these forests, replanted with trees desired for both their economic and societal benefits, have not offered the feedback that scientists desired. In fact, it has been shown that the reforesting processes in Europe have actually increased global warming by point one degrees Celsius. This is largely due to a sharp spike in the population of fast-growing, commercially valuable conifer trees at the expense of broad-leaved trees. These conifer trees are darker and reflect less sunlight than broad-leaved trees and lose less water to evaporation, a process which cools the surrounding air. Scientists have now began to study how micromanaged regrowing of forestland can effect climate in other parts of the world.
