Let’s learn about the Arctic

The far North is a mix of vast tundra and icy waters

The Arctic — that region that makes up the far North of our planet — has now emerged from its long winter night. Snow has started to melt. And the sea ice that covers the Arctic Ocean will begin to melt and shrink, too.

The freeze-and-melt pattern of the Arctic has long been the norm, but climate change is now altering things. Much of that ice used to last even through the summer. But sea ice is melting more and more each year, and may one day soon disappear entirely. Erosion is threatening Arctic communities. And scientists worry about what may happen as long-frozen soil, called permafrost, continues to thaw.

But scientists are studying more than just climate change in the Arctic. They’re tracking polar bears and other iconic species. They’re studying what habitat freshwater fish prefer. And they’re taking a look at the surprising activity of what lives in the 24/7 darkness of the Arctic sea in the middle of winter.
