The Arctic is melting so quickly that it may disappear by 2070.
The first in-depth scientific study on how global warming is affecting the area found the ice there is half as thick as it was thirty years ago.
They say the main cause is pollution, which traps heat in earth's atmosphere, causing our temperatures to rise.
If the ice does melt, it could cause lots of extreme weather, as well as wiping out animals like polar bears which live on the glaciers.
