Dr. Larry Cathles, Cornell University NY-US presents: Solar Impact on Climate Change. The talk presents an energy balance assessment of climate from the Last Glacial Maximum (37,000 years ago) to well past the exhaustion of fossil fuels. Future warming may be easier to control than commonly feared, greenhouse emissions will control future warming, past changes tell the severity of future warming, and natural fluctuations will continue to be significant. Most importantly, uncertainty in the magnitude of future warming will prove impossible to reduce, and we will have to move forward in the face of this uncertainty. Ways to do this are suggested.

Forward projection of base case (black) curve that meets the Paris accord by accelerating non-fossil fuel development by 0.19% per year. And where the temperature rises to just 2C, and then drops to ~1.5C (relative to the pre-industrial average) as fossil fuel use ends because it is displaced by non-fossil sources or the fossil fuels are exhausted.

Biography: After doctoral research on the viscosity of the earth’s mantle at Princeton, Cathles spend 7 years at Kennecott Copper Corporations Ledgemont Laboratory researching the relation of ore deposits to plate tectonics, and in situ and heap leaching methods of mining copper. Joining the faculty of the Pennsylvania State University in 1978, he researched the formation of massive sulfide deposits newly-discovered at mid-ocean ridges from the perspective of similar deposits being mined in the failed rifts of Japan. At the Chevron Oil Field Research Company (1982-86) he developed genetic and exploration models for gold and sulfide deposits, and investigated CO­2 generation during steam flooding. Since 1986 he has been at Cornell University. His investigations there have included oil and gas generation and migration in the Gulf of Mexico, how capillary seals contain over-pressured fluids for hundreds of millions of years and allow basins to suddenly expel brines and form MVT-type sulfide deposits, how vein halos indicate porphyry copper deposits are the result of barely-contained hydrothermal explosions, and how chemical alteration can be used to infer patterns in fluid flow. Recently his research has involved the impact of natural gas emissions on climate change, separating natural and anthropogenic drivers of climate change, and glacial isostatic calculations of sea level change.
