The fourth of 4 NAS reports is now out. Summaries of all 4 are readable on the NAS website. Could look here first: National-Academies.org | Newsroom or here: America's Climate Choices Youse can read them (all) online or get free summary pdfs, or buy the whole things. Those who come in via 3rd world computers can generally download NAS pdfs for free. Like me My compensation for no YouTube. Anyway, they may be of interest.
