Geoengineering: Whiter skies?
[1] One proposed side effect of geoengineering with stratospheric sulfate aerosols is sky whitening during the day and afterglows near sunset, as is seen after large volcanic eruptions. Sulfate aerosols in the stratosphere would increase diffuse light received at the surface, but with a non-uniform spectral distribution. We use a radiative transfer model to calculate spectral irradiance for ide...
متن کاملCloudy Skies
Standard Gaussian-type statistics are not really adequate to describe atmospheric variability; this traditional approach implicitly dismisses fluctuations as "noise" of use only in computing a standard deviation which, together with the mean, presumably varies so little in space and time that one can meaningfully speak of "climatological" values. In geophysics, unfortunately, this approach ofte...
متن کاملGeoengineering as Collective Experimentation
Geoengineering is defined as the 'deliberate and large-scale intervention in the Earth's climatic system with the aim of reducing global warming'. The technological proposals for doing this are highly speculative. Research is at an early stage, but there is a strong consensus that technologies would, if realisable, have profound and surprising ramifications. Geoengineering would seem to be an a...
متن کاملStratospheric Aerosol Geoengineering
In response to global warming, one suggested geoengineering response involves creating a cloud of particles in the stratosphere to reflect some sunlight and cool Earth. While volcanic eruptions show that stratospheric aerosols cool the planet, the volcano analog also warns against geoengineering because of responses such as ozone depletion, regional hydrologic responses, whitening of the skies,...
متن کاملHow to govern geoengineering?
he Paris Agreement aims to limit the global temperature rise to 1.5° to 2°C above preindustrial temperature, but achieving this goal requires much higher levels of mitigation than currently planned. This challenge has focused greater attention on climate geoengineering approaches, which intentionally alter Earth’s climate system, as part of an overall response starting with radical mitigation. ...
