Methane – The Bigger Picture in Climate Change – YouTube

Dr. Richard Nolthenius – Chair of the Dept of Astronomy at Cabrillo College, California – gives a 17 minute talk on Nov 8, 2019 at the Erica Schilling Auditorium at Cabrillo College. This followed the showing of the new documentary “Blowout” by AK Productions on the dangers of fracking in the U.S. to ground water and greenhouse gas emissions. Dr. Nolthenius’ Presentation puts methane emissions into the larger context of future climate change. It includes the implications of how new determinations of Equilibrium Climate Sensitivity (ECS) will accelerate methane emissions from wetlands and thawing permafrost, triggering climate tipping points. It discusses subsea methane hydrates stability, the Compost Bomb Instability, and also how fracking will adversely affect the ability to permanently sequester CO2 underground.
