Lima Climate Change Conference – December 2014
The 20th session of the Conference of the Parties and the 10th session of the Conference of the Parties serving as the Meeting of the Parties to the Kyoto Protocol took place from 1 to 12 December. COP 20/CMP 10
was hosted by the Government of Peru, in Lima, Peru.
On December 8, GFDL’s Director, V. “Ram” Ramaswamy
hosted a NOAA Side Event at the U.S. Center, titled “Understanding and Predictability of Regional Climate and Extremes”. Wayne Higgins (CPO) and Berrien Moore (Dean, College of Atmospheric and Geographic Sciences, University of Oklahoma) participated remotely, followed by a presentation by Ram. A question-and-answer period concluded the one-hour event. During the session, Ram featured animations showcasing GFDL?s high-resolution climate predictions and projections, using NASA?s Hyper-Wall.
Ram?s talk described NOAA?s pioneering research of the Earth System to diagnose global and regional changes in climates using state-of-the-art numerical models. Building on the latest scientific understanding of regional climate phenomena and extremes, he demonstrated the progress towards predictability, using model simulations. Ram?s talk included examples of variations in sea-surface temperature and biogeochemical changes, pollution episodes caused by intra- and inter-continental transport of aerosols, heat waves, seasonal precipitation and snowpack, drought, and frequency of hurricanes.
