So, what’s up with that? Is global warming slowing down? Or going backwards?
We wish that were true! But no. Many conditions affect weather. It so happens that during winter 2010, one of those conditions was a bit unusual.
The condition is the “Arctic Oscillation.”
Here’s what that means. Air moves from one place to another around the world because of air pressure. In some places, the air is thicker, or more dense, than in other places. We say the air pressure is higher. Air moves from areas of higher pressure to areas of lower pressure. That is wind!
