Karl the Fog – June 25

As poet Carl Sandburg observed: "The fog comes on little cat feet. It sits looking over harbor and city on silent haunches, and then moves on." What is the nature of The City's renowned Karl the Fog? Do those super-fine droplets consist of more than just water? Why does our beloved(?) Karl creep over the Bay Area so often, and will that creeping continue in light of climate change?

Our speaker, Alicia Torregrosa, knows Karl inside and out. As Program Officer at the U.S. Geological Survey, Alicia is a physical scientist who led the USGS Pacific Coastal Fog Project, yielding an international and interdisciplinary expansion of coastal fog research.
