CC & NSSS: Dr. Warren Washington: Climate Modeling, Societal Impacts and Environmental Justice

SAND # 2012-6890 P Climate Change & National Security Speaker Series Everyone knows that recent climate has changed almost everyone. The most recent Intergovernmental Panel on Climate Change Assessment Report (IPCC AR4) has convinced most climate scientists that humankind is changing the earth's climate and that significant global warming is taking place. Some scientist are skeptical of the IPCC view and think the observed changes result from natural climate variabiility or other causes. A brief review of recently observed 20th century climate change will be presented and compared with climate model simulations. These computer simulations are extended into the 21st century and beyond in preparation for the next IPCC assessment. A brief description of what is in climate models will be given with an emphasis on the physical and computational aspects. Computer simulations and animations of climate and future climate change will be shown from low and high carbon emission scenarios. (Maelyn Melville 01932) 858EL/L2000 On Demand
