Researchers in Finland have found a way to combat global warming: Reindeer!

Could Rudolf be the solution in the fight against disastrous global warming?

Researchers at the University of Turku, Finland, have found a way to protect humanity from dangerous global warming - Reindeer! 

According to Professor Lauri Oksanen of the University of Turku, grazing by reindeer keep arctic vegetation in check, thus reducing the solar heat absorption that leads to a self-reinforcing cycle of climate change.

Snow cover and mostly barren tundra reflect large portions of the sun's rays. When darker shrubs and trees spring up in arctic areas they absorb more energy, heating up their surroundings and the earth's atmosphere.
Researchers in Finland have now carried out a comparison between an area in Norway where reindeer are not allowed to graze in the summer, and a similar area in Finland where grazing reindeer have kept shrubs and tree from growing.
They have found that the heat radiated by the overgrown area in Norway is at a much higher level.
"The heat difference between what happens there and in the Finnish area during three spring months, March, April and May, would be enough to melt a cubic kilometre of ice. That is no small matter,” explains Professor Lauri Oksanen.
