Abstract:  Human-caused atmospheric change is on a pace similar to changes caused by large asteroid impacts. Its magnitude is approaching those caused by slow or rare large events in Earth history.  Humans are on track to impose a climate change influence in just 200 years comparable to what comes naturally about once per geologic epoch or period. Already, anthropogenic climate change has a magnitude typical of Ice Age climatic oscillations. The present global climate is warmer than ever in the history of civilization and going back 100,000 years. Somewhat controlled CO2 emissions would make early 22nd century conditions like those last experienced by protohuman Lucy. “Business as Usual” (exponentially growing) combustion would produce a “Hothouse” climate like in the Eocene, 40-50 Ma. 

In this presentation, I will provide evidence of climate changes on other planets and moons, drill into geological deep time here on Earth, delve into anthropogenic climate change and extreme weather, and then project what’s coming next. The situation we face is tough, but not hopeless.  

Biography:  Jeffrey Kargel is a geologist (BS, MS) and planetary scientist (PhD) and currently works on Earth’s glaciers and hydrogeological hazards and on the geology, geochemistry, and climates of Venus, Mars, Titan, and Pluto. He is the former Director of a 35-nation glacier remote sensing consortium, GLIMS (Global Land Ice Measurements from Space), worked at the University of Arizona and the US Geological Survey, and currently he is a Senior Scientist at the Planetary Science Institute.  For information please see:  https://scholar.google.com/citations?user=ge-YXJwAAAAJ&hl=en.
