Sulfr hexafluoride: The Truths and Myths of this Greenhouse Gas

Sulphur hexafluoride, commonly known as SF 6, has made a splash in the mainstream media of late. Several articles are pointing the finger at the growth in renewables—specifically wind turbines—as being responsible for the growth in SF 6 emissions, with some going as far as saying that the gas is the energy industry’s dirty little secret. In this spirit of transparency, we asked several experts from NTNU and SINTEF to separate the truths from the myths.Get price

THE NOAA ANNUAL GREENHOUSE GAS INDEX (AGGI)

IntroductionObservationsRadiative Forcing Calculations2018 ResultsReferencesIncreases in the abundance of atmospheric greenhouse gases since the industrial revolution are mainly the result of human activity and are largely responsible for the observed increases in global temperature [IPCC 2014]. However, climate projections have model uncertainties that overwhelm the uncertainties in greenhouse gas measurements. We present here an index that is directly proportional to the change in the direct warming influence since 1750 (also known as climate forcing) supplied from these gases. Because it is based on the observed amounts of long-lived greenhouse gases in the atmosphere, this index contains relatively little uncertainty. The Intergovernmental Panel on Climate Change (IPCC) defines climate forcing as “An externally imposed perturbation in the radiative energy budget of the Earth climate system, e.g. through changes in solar radiation, changes in the Earth albedo, or changes in atmospheric gases and aerosol particles.” Thus climate forcing is a “change” in t...Get price
