  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

    Impacts of Climate ChangeRoe IndicatorsReferencesThe changing climate affects society and ecosystems in a variety of ways. For instance: 1. A warmer climate is expected to both increase the risk of heat-related illnesses and deaths and increase certain types of air pollution. 2. More severe heat waves, floods, and droughts are expected in a warmer climate. These may reduce crop yields. 3. Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. 4. Climate change can alter where species live and how they interact, which could fundamentally transform current ecosystems. These and other aspects of climate change are disrupting peoplelives and damaging some sectors of the U.S. economy.4This has led many state and local governments to prepare for these impacts through “adaptation” (i.e., planning for the changes that are expected to occur).
