Henrik Svensmark discusses how solar activity modulates cosmic rays, which ionize the atmosphere and can help form aerosols that grow into cloud condensation nuclei, potentially altering clouds and Earth’s energy balance. He describes lab experiments showing more aerosols with increased ionization, critiques models that predicted no cloud effect, and presents observations from Forbush decreases where drops in cosmic rays are followed days later by reduced aerosols, cloud changes, and radiative-budget responses. He argues solar-cycle forcing may be ~1–1.5 W/m² and could affect CO2 sensitivity. On longer timescales, he links supernova-driven cosmic-ray variations to glaciations, ocean temperature, organic carbon burial, oxygen production, and biodiversity, while noting funding and career pressures.

Randall Bock argues opioids have dual legal and illicit markets and that most prescribed users don’t become street addicts. He recounts refusing drug-seekers (“Dr. No”) and later using buprenorphine as a temporary bridge, advocating a 4–6 month taper to sobriety rather than lifelong “maintenance.” He claims methadone maintenance, originated at Rockefeller University and expanded nationally via Nixon-era policy and Medicaid incentives, aimed to curb New York City crime but instead seeded the first wave of the opioid crisis and spread heroin use. He challenges the “addiction as disease/insulin” analogy, cites Vietnam vet recovery and Rat Park, and promotes his book “Withdraw to Freedom.”

Thomas Kurz discusses chapters from his book Why There Is No Climate Crisis, citing positive reviews, then explains the greenhouse effect and argues CO2’s warming is limited and logarithmic. He claims doubling CO2 yields about 3 W/m² effective forcing, or ~0.9°C via Stefan–Boltzmann calculations, and says even burning all known fossil fuel reserves would add under ~1°C. He argues “climate crisis” claims rely on compounded positive feedbacks in IPCC models, but says observations show models overpredict warming, relative humidity aloft is declining, and a predicted tropical hotspot is missing. He attributes discrepancies to cloud/aerosol cooling, proposing an Earth “thermostat” and net slightly negative feedback.
