Tom interviews Anika Sweetland, who argues Earth’s climate changes in predictable natural cycles and that today is relatively cool in a 65‑million‑year context. Using graphs and books by Gregory Wrightstone, she describes ice-age rhythms linked to Milankovitch cycles and 1,500‑year Dansgaard–Oeschger cycles, including the Medieval Warm Period and Little Ice Age, and claims solar activity and cosmic rays better correlate with temperature than CO2. She says the IPCC smooths data and governments use fear for control, while net-zero policies are wasteful and geoengineering in the UK is concerning. Sweetland recounts university climate studies as CO2-focused indoctrination, discusses backlash and support online, and previews a part two on the IPCC.00:00 Meet Anika Sweetland04:40 Ice Ages and Long Cooling07:18 Milankovitch Cycles Explained09:14 Dansgaard Oeschger Cycles11:04 Medieval Warmth and Little Ice Age14:01 Sun Cosmic Rays and Clouds18:21 CO2 Claims and Propaganda21:07 Her Climate Degree Experience23:22 Education Debate and Models27:47 Conference Disruption and Activism30:34 Social Media Pushback34:54 Part Two and Wrap Up35:22 Energy Policy and Geoengineering39:18 Final Thanks and Goodbyehttps://x.com/anika_climateThe 16th International Conference on Climate Change: https://climateconference.heartland.org/Anika on being bombarded with global warming propaganda: https://x.com/anika_climate/status/2037550091544785239=========Slides, summaries, references, and transcripts of my podcasts: https://tomn.substack.com/p/podcast-summariesMy Linktree: https://linktr.ee/tomanelson1

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
