| What Are the "Known Knowns" of Climate Change Issue1 #472964 What do we truly know about the climate system and climate change? A great deal. We understand how the climate system works, we know we are introducing significant change into the climate system, and we can observe how the climate system is responding to those changes. We also know how the climate system has responded to conceptually similar changes during the history of the planet. That said, there are plenty of known unknowns, and a lot of concern over unknown unknowns. |
