Atmospheric Carbon Dioxide and Aerosols: Effects of Large Increases on Global Climate

Rasool, S. I., Schneider, S. H.·1971·Science

Abstract

Effects on the global temperature of large increases in carbon dioxide and aerosol densities in the atmosphere of Earth have been computed. It is found that, although the addition of carbon dioxide in the atmosphere does increase the surface temperature, the rate of temperature increase diminishes with increasing carbon dioxide in the atmosphere. For aerosols, however, the net effect of increase in density is to reduce the surface temperature of Earth. Because of the exponential dependence of the backscattering, the rate of temperature decrease is augmented with increasing aerosol content. An increase by only a factor of 4 in global aerosol background concentration may be sufficient to reduce the surface temperature by as much as 3.5 degrees K. If sustained over a period of several years, such a temperature decrease over the whole globe is believed to be sufficient to trigger an ice age.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Rasool and Schneider (1971) proposed that an increase by a factor of 4 in global aerosol concentrations could be enough to trigger an ice age.

    “An increase by a factor of 4 in global aerosol concentrations, 'which cannot be ruled out as a possibility,' could be enough to trigger an ice age (Rasool and Schneider 1971).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
