Climate Change: A Scientist's Perspective, Ralph Cicerone( More about event)
Earth's climate is changing, as can be seen from measurements of rising air and water temperatures, decreasing amounts of polar ice and rising sea levels worldwide over the past three decades or so. Human-caused increases in atmospheric greenhouse gas concentrations, chiefly carbon dioxide from fossil-fuel combustion, are the likely cause of contemporary climate change. Recent climate data will be presented along with evidence linking human energy usage to these changes. Ralph J. Cicerone is President of the National Academy of Sciences and Chair of the National Research Council. His research on atmospheric chemistry, the radiative forcing of climate change due to trace gases, and the sources of atmospheric methane, nitrous oxide and methyl halide gases was recognized by the Franklin Institute with the 1999 Bower Award and Prize for Achievement in Science. The American Geophysical Union, the worldÃÂ¢ÃÂÃÂs largest society of earth scientists, awarded Cicerone its 1979 James B. Macelwane Award for outstanding contributions to geophysics by a young scientist and its 2002 Roger Revelle Medal for research contributions to the understanding of EarthÃÂ¢ÃÂÃÂs atmospheric processes, biogeochemical cycles, and climate system. The World Cultural Council honored him with the 2004 Albert Einstein World Award in Science.
