Antarctica's coldest winter on record doesn't disprove global warming

Dan Riskin on how climate change is measured A research centre in Antarctica just had the coldest winter on record. Dan Riskin explains why that doesn't mean climate change isn't real.

We've all heard it before.

The weather gets cold, and the jokes come out. "Whatever happened to global warming?"

Sometimes, though, it's not a joke. Sometimes, it's a sign that the person asking the question doesn't fully grasp the science behind the climate change. They may not realize that one data point – Antarctica's coldest winter on record, for example – isn't enough to invalidate a wider trend.
