William van Wijngaarden: “Evidence doesn’t support climate hysteria” | Tom Nelson Pod #403

William Van Wijngaarden explains the greenhouse effect as higher, colder radiating layers caused by more greenhouse gases, noting roles of CO2, water vapor, ozone, methane, and N2O, and emphasizing cloud uncertainties. He cites rising CO2 (320 ppm in 1960 to ~430), N2O and methane increases, but highlights non-monotonic temperature history including a 2000–2016 “hiatus,” and claims climate models overpredict warming by about threefold. He argues data do not show worsening trends in Arctic ice (recently flat), hurricanes, tornadoes, wildfires, or precipitation, and glacier retreat began after the Little Ice Age. He says ocean pH would drop from 8.18 to ~7.93 with doubled CO2, corals grow fastest in warm water, eliminating cattle would cool ~0.05°C, and fertilizer cuts risk food shortages. He calls for more observations (clouds, Argo oceans) and concludes warming is modest (~1°C ±1°C) and net-zero policies lack evidence.00:00 Meet The Guest03:19 Key Greenhouse Gases05:44 Temperature Record Mysteries07:20 Models Versus Reality08:39 Infrared Spectrum Explained10:53 Satellites Confirm Physics11:58 Clouds And Uncertainty15:10 Arctic Ice Reality Check16:28 Glaciers Wildfires Hurricanes20:12 Natural Variability Lesson21:52 Ocean Acidification Facts23:52 Corals And Warm Water24:48 Methane And Livestock Myth27:06 Fertilizer And Food Tradeoffs28:51 CO2 Greening Benefits30:56 Big Picture Conclusions33:04 New Research Water Vapor34:04 Observations Over Modeling36:05 Measuring Oceans And Ice39:21 Looking Ahead Calmly41:16 Final Thanks And WrapWilliam’s website: https://wvanwijngaarden.info.yorku.ca/=========Slides, summaries, references, and transcripts of my podcasts: https://tomn.substack.com/p/podcast-summariesMy Linktree: https://linktr.ee/tomanelson1
