Dr. Shaviv, a professor of physics at the Hebrew University of Jerusalem, will discuss the evidence demonstrating that the sun has a large effect on climate and the physical mechanism for this link.
He will show that by considering the solar forcing, a much more consistent picture emerges for the observed 20th century climate change, with part of it being solar and part being anthropogenic.
In this picture, however, Earth's climate sensitivity is modest and therefore the 21st century global warming is expected to be modest as well (about 1°C). Date: March 21, 2013 Time: 11:30am-1pm Where: Rayburn House Office Building, Room 2325, Washington, D.C.
