PEEC: The event is free to the public

Chick Keller will wrap up Pajarito Environmental Education Center’s Climate Change series with a talk titled, “Global Warming: What We Know and What the Current Hot Topics Are,” at 7 p.m. Dec. 14. The talk is free and open to the public.
It is now well established that human emissions of so-called Greenhouse Gases are warming the planet.  Even top critics agree on the observed warming, that humans are the cause of rising CO2 in the atmosphere, and that this is causing warming.
They deny however, that processes feedback positively in response to CO2 warming, thereby adding to the warming. And so the discussion has now moved to just how much warming there will be.
Critics point to recent information that suggests a 60-year cycle in ocean warming and cooling contributed to rapid warming in the late 20th century and to lack of warming in the past eight years or so.
This talk will review what we know and what the current findings are about the effect of this multi-decadal ocean cycle as well as best estimates of solar effects.
Keller is a retired scientist from Los Alamos National Laboratory. He came to Los Alamos as a graduate student in 1967 and became a permanent staff member in 1969 upon receiving his doctorate in astronomy from Indiana University.
His professional research has been heavily involved in climate studies and he has taught a course in this at the University of New Mexico-Los Alamos. For many years he was director of the lab’s UC Institute of Geophysics and Planetary Physics.
