Posted by This Land is Our Land On Friday (September 27, 2013), the Intergovernmental Panel on Climate Change (IPCC) released a landmark study showing unequivocal evidence that Earth’s climate system is warming. To accompany the data in the IPCC report, the U.S. National Aeronautics and Space Administration (NASA) has produced a new video that shows what changes in temperature and precipitation can be expected for the 21st century if CO2 concentrations in the atmosphere continue to rise from the current level of approximately 400 parts per million (ppm) to an anticipated 670 ppm by 2100. The video illustrates what a warmer world will look like and identifies what regions will likely experience the most warming. In general, warming is expected to be more pronounced over land than in the ocean and the largest increases in temperature are expected to occur across the Northern Hemisphere.
