Russian scientists: Earth can expect a new ice age

“Everything on Earth is cyclical — a warm period is followed by a cold one, and vice versa. We are currently in a warm period. However, unlike past periods, it is advancing too quickly. Over the last 100 years, we have seen a drastic migration of animals and plants to the North.” Thus every year, trees are rising by about 1.5 feet toward the peaks of the northern mountains, and they are encroaching on the tundra.  http://m.rbth.ru/articles/2013/01/15/russia_launches_year_of_the_environment_21891.html
