Freezing cold last week. Springlike this week. What’s a kid to do in this type of winter?!?! Weather is what happens in the atmosphere day to day. Climate is how the atmosphere behaves over long periods of time. The extreme cold brings out climate change skeptics, so it is important to emphasis that occasional cold snaps do not change the overall trajectory of our warming planet. Winters have been warming steadily over the past century, and even faster in recent decades.
