Do we know the Earth is warming? We’ll examine the many different indicators that our planet is warming. We’ll look at the heat building up in our climate system and how that affects heat records and sea level rise. We’ll talk about the challenges of putting together a global temperature record. We’ll even look at what’s been causing some recent intense winters in the Northern Hemisphere.
