Document Summary
To a brighter future: national council for science and the environment building. Brighter future with more jobs and security, and penguins and pikas. Provide an up to date summary of scientific climate change . Global warming=unavoidable consequence of our actions, based on well-understood physics. We are turning up the earth"s thermostatand the earth is warming. Climate vs weather weather is daily average while climate is long term average. No slowdown in energy accumulation in the earth system. Short trends of climate cooling are not significant but longer trends are. The world is variable because of volcanoes, el ninos . The world is warming mostly because of co2. Warming over the last century: unequivocal, from cautious ipcc (intergovernmental panel on climate. Change: direct thermometer measurement: air, ocean water, ground, balloons, satellites, mass loss from almost all glaciers, including those getting more snow, great majority of biology shifts in direction expected for global warming.
