Climate change is described in some quarters as a "crisis" and in others as a "hoax", with a range of views in between. How can one square this with climate science, which should be more objective? This talk, led by Nadir Jeevanjee, will emphasize that there is a spectrum of climate science, ranging from well-established, "settled" science (such as global warming due to anthropogenic CO2) to highly uncertain frontier topics (such as various proposed "tipping points"). To properly interpret climate science, one must acknowledge the existence of this spectrum, and appropriately place climate and weather phenomena within it. 

Jeevanjee studies the physics of clouds, radiation, and climate, using a hierarchy of approaches ranging from pencil-and-paper theory to comprehensive computer simulations. He currently is a Research Physical Scientist at NOAA's Geophysical Fluid Dynamics Laboratory. This event will be co-sponsored by the Science, Technology, and Society network at Temple University.
