California has many pressing issues, but one surely at or near the top of the list is the reliability of its water supply.
The ecosystem depends on it, of course, but so do the huge farming, industrial and residential communities in a state with seasonal rainfall and glaciers and snow packs, summertime water banks essentially, that are shrinking as the planet warms.
Richard Luthy, a civil engineering professor at Stanford University, will speak on "Facing Scarcity: The Water Crisis in California" during a Cafe Scientifique presentation at 6 p.m. Tuesday, Feb. 9, at the SRI International Building at Middlefield Road and Ringwood Ave. in Menlo Park.
Doors open at 5:15 p.m. and close when the room reaches capacity. Bring your own coffee cup.
Cafe Scientifique, sponsored by the pharmaceutical firm ROXRO PHARMA and SRI, is a monthly meeting where the public can explore and debate scientific and technological issues in a non-academic setting.
Mr. Luthy has chaired the National Research Council's Water Science and Technology Board and is former president of the Association of Environmental Engineering and Science Professors.
The event includes a drawing for a $30 gift certificate for Kepler's Books at 1010 El Camino Real in Menlo Park. Kepler's adds the names of drawing participants to its mailing list.
