Sentences with phrase «sulfates effect climate»

Not exact matches

Sulfate aerosols have a cooling effect on the climate, which has led some researchers to suggest that continued reductions will lead to greater global temperature increases in coming decades.

It is my understanding that the uncertainties regarding climate sensitivity to a nominal 2XCO2 forcing is primarily a function of the uncertainties in (1) future atmospheric aerosol concentrations; both sulfate - type (cooling) and black carbon - type (warming), (2) feedbacks associated with aerosol effects on the properties of clouds (e.g. will cloud droplets become more reflective?)

The second IPCC report, published in 1995, invoked the «sulfate - aerosol effect» and produced the memorable but essentially meaningless phrase that «the balance of evidence suggests a discernible human influence on global climate.»

That same reference finds that the statistical estimates for the temperature effect of volcanic sulfates and ENSO (and effects of ENSO on atmospheric CO2) are consistent with estimates derived from climate models and empirical analyses.

On one hand, the reduction in global SO2 emissions reduces the role of sulfate aerosols in determining future climate toward the end of the 21st century and therefore reduces one aspect of uncertainty about future climate change (because the precise forcing effect of sulfate aerosols is highly uncertain).

Bauer, S.E., M.I. Mishchenko, A.A. Lacis, S. Zhang, J.P. Perlwitz, and S.M. Metzger, 2007: Do sulfate and nitrate coatings on mineral dust have important effects on radiative properties and climate modeling?

This is what the IPCC models think the climate would be doing without anthropogenic effects (both warming CO2 and cooling sulfates, for example).

Climate engineering: To counter the effects of heat - trapping greenhouse gases, some experts have proposed artificially cooling the planet by injecting sulfates into the stratosphere, which would mimic the effects of a major volcanic eruption.
