PHYS 0847 Lecture Notes - Lecture 10: Diesel Fuel, 100 Feet, Greenhouse Effect
Document Summary
The intergovernmental panel on climate change (ipcc) periodically reports a consensus opinion that (almost) all of the scientific community agrees with. The ipcc consensus is not the whole story, but it represents the best, most factual summary available of human knowledge about climate change and global warming.

(cid:863) Note: these notes use the 2014 ipcc report as a source for most of this information. As it happens, our textbook author, richard muller, is a famous climate change skeptic. He started his own project called berkeley earth to check many of the ipcc claims for himself.
