Project Director Ron Smith explains the nature of gravity waves, how they propagate high into the stratosphere and then collapse, creating Brewer-Dobson circulation cells that influence global weather. His international team of researchers spent most of the summer flying the night skies New Zealand to study the phenomenon.
Yale Professor Ken Gillingham welcomes participants in this YCEI sponsored workshop that brings together climate change scientists and economists whose modeling efforts hinge on the need to accommodate anticipated climate change in a warming world.
He sets the stage for the day’s conversations by reviewing the just released IPCC 5th Assessment Report, some of its findings, and the unique language that the IPCC uses to describe uncertainty in climate sensitivity, the key parameter that concerns economists and climate scientists.
