Thomas Kurz discusses his upcoming book, Why There Is No Climate Crisis (Kindle in May, print in June), and argues modest warming is largely natural, claiming the IPCC obscures evidence of past climate variability. He explains paleoclimate proxies (oxygen isotopes, carbon-14, beryllium-10) and links climate shifts to Milankovitch cycles, solar cycles, galactic cosmic rays influencing clouds, and ocean oscillations (AMO/PDO). Using temperature reconstructions, glacier, treeline, sea-level, historical freeze, agriculture, insect, and civilization records, he says warm periods brought prosperity while cold periods drove drought, famine, disease, and upheaval. He concludes about half of post-1850 warming is natural, warming is generally beneficial, and future cooling is likely.
