3. PaleoClimate

Part three of my four part series on the IPCC is about paleoclimate: Chapter five. Otto Bliesner visited CU Boulder to personally deliver the message in the multi-part CIRES seminars, and this chapter says a lot by looking at the earth’s history, most notably through ice cores. Chapter five is where much of the evidence comes in to proving that the temperature has increased because it shows that Earth’s natural cycles have been disrupted. Weather it is tree rings, ice cores, permafrost, or other records, the evidence points to a gap between what should be happening (what we could reasonably expect from records and Earth’s experience), and what is.
