Melting Arctic sea ice doubles the chances of harsh winters in other parts of the world

When most people hear the term "global warming," they naturally think of air temperature. In reality, more than 90 percent of the warming caused by greenhouse gases happens in the oceans. Much of this warming takes place in the waters in and around the Arctic Ocean, leading to increasingly rapid melting of sea ice. A new study links this melting to cold, harsh winters that are becoming more common in parts of the world.
