This week I read an article on global warming.  It was about how a forest is forming in the Arctic tundra. Scientists predicted this would happen but not this fast.  These forest trees started out as little shrubs.    Scientists anticipated that these shrubs would eventually form into trees in over a couple centuries.  They were very wrong.  It only took thirty to forty years for them to grow from small shrubs into two meter tall trees.  Now you may be thinking to yourself, “Why is this a bad thing? Trees are good for the environment.”  Well, the growth of these trees is warming the Arctic tundra which is not good because the Arctic tundra is covered in ice.  The trees warm the area and will make the ice melt faster in these areas which is not good for the Earth.  All this is happening in a one hundred thousand square kilometer area between Finland and Siberia.  Scientists knew that the sample area was a warmer part of the Arctic tundra than others.  Since it is a warmer part, it is easier for plants to grow.   When the shrubs start to grow the plants spread and start to grow in other places.   I hope scientists can overcome this problem and find a solution to help our environment and prevent global warming from spreading faster.
