As well as monitoring deforestation, a cause of global warming, satellites are used to observe its effects. In the Arctic, the U.S. National Snow and Ice Data Center uses orbiting instruments to track the declining sea ice. Instruments and satellites built by Astrium, Lockheed Martin Corp. and Japan’s NEC Corp. are all part of the effort. Satellites can also track glaciers, coastal erosion and ocean currents.
“Climate change monitoring goes beyond measuring carbon in the atmosphere,” said Nancy Colleton, president of the Institute for Global Environmental Strategies in Arlington, Virginia. “We must have global, long-term data and information to help us understand how a change in one part of the world may impact another.”
