Sentences with phrase «sulphate aerosols in the stratosphere»

One wonders what we would do if injecting sulphate aerosols in the stratosphere were to cause a planet - wide cooling event far beyond the original intentions

Sulphate aerosols in the stratosphere (which were the main topic of this piece and these Climate Feedback posts) and mirrors / refractors in space (also in that piece, and in this paper by Roger Angel) both have the potential to provide as much by way of negative forcing as a doubling of CO2 provides by way of positive forcing.

One knob that we could control: The amount of sulphate aerosols in the stratosphere.

For instance, given the physics of sulphate aerosols in the stratosphere (short wave reflectors, long wave absorbers), it would be surprising if putting in the aerosols seen during the Pinatubo eruption did not reduce the planetary temperature while warming the stratosphere in the model.

The story revolves around a paper that Paul Crutzen (Nobel Prize winner for chemistry related to the CFC / ozone depletion link) has written about deliberately adding sulphate aerosols in the stratosphere to increase the albedo and cool the planet — analogous to the natural effects of volcanoes.

Not exact matches

In this case, large amounts of sulphate aerosols (small particles) are injected into the stratosphere by large explosive eruptions (the most recent one being Mt. Pinatubo in 1991In this case, large amounts of sulphate aerosols (small particles) are injected into the stratosphere by large explosive eruptions (the most recent one being Mt. Pinatubo in 1991in 1991).

Both sulphate aerosols and CO2 have their influence in the (lower) troposphere, while solar and volcanic have their highest influence in the stratosphere, this is essential in the discussion.

In this effort they have been joined by the Bipartisan Policy Center, a conservative Washington non-profit, whose report last month rebranded geoengineering «climate remediation» so as to make sulphate aerosol injections into the stratosphere sound healthful.

Although we focus on a hypothesized CR - cloud connection, we note that it is difficult to separate changes in the CR flux from accompanying variations in solar irradiance and the solar wind, for which numerous causal links to climate have also been proposed, including: the influence of UV spectral irradiance on stratospheric heating and dynamic stratosphere - troposphere links (Haigh 1996); UV irradiance and radiative damage to phytoplankton influencing the release of volatile precursor compounds which form sulphate aerosols over ocean environments (Kniveton et al. 2003); an amplification of total solar irradiance (TSI) variations by the addition of energy in cloud - free regions enhancing tropospheric circulation features (Meehl et al. 2008; Roy & Haigh 2010); numerous solar - related influences (including solar wind inputs) to the properties of the global electric circuit (GEC) and associated microphysical cloud changes (Tinsley 2008).

There is no obvious answer, unless you look to stratospheric aerosol cooling — in the stratosphere, you'd need about 10 % of the sulphates you'd require in the troposphere for the same cooling effect.
