Antarctica's coldest winter on record doesn't disprove global warming
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.
How do you respond to someone like that? CTV News Science and Technology Spcialist Dan Riskin gives it a try in this week's Riskin Report.
