Summary:

• **Forests are Moving North Because of Climate Change** - Scientists using NASA satellites have discovered that boreal forests (the large forests near the North Pole) are slowly moving northward as Earth gets warmer. This is happening because trees can now grow in areas that used to be too cold and frozen.

• **What This Means for Our Planet** - When forests move north into areas that were once frozen tundra (empty, icy land), it changes how much sunlight the ground reflects back into space, which can make Earth even warmer. This is one way that climate change creates a chain reaction that affects our whole planet.
