Global Warming? The Early Twentieth Century
As man is now changing the composition of the atmosphere at a rate which must be very exceptional on the geological time scale, it is natural to seek for the probable effects of such a change. From the best laboratory observations it appears that the principal result of increasing atmospheric carbon dioxide would be a gradual increase in the mean temperature of the colder regions of the earth. ...
متن کاملMulticollinearity Reconsidered
In this paper we intend to improve the explanatory power of regressions when the deletion method is used for the remedy of Multicolinearity. If one deletes the variable (s) that is (are) responsible for Multicolinearity, he loses some information that is not common between the deleted variable (s) and the other remaining variables in the regression. To improve this method, we run the deleted va...
متن کاملTransient reducing greenhouse warming on early Mars
The evidence for abundant liquid water on early Mars despite 3 the faint young Sun is a long-standing problem in planetary research. Here 4 we present new ab initio spectroscopic and line-by-line climate calculations 5 of the warming potential of reduced atmospheres on early Mars. We show 6 that the strength of both CO2-H2 and CO2-CH4 collision-induced absorp7 tion (CIA) has previously been sig...
متن کاملSulfur - Related Greenhouse Warming on Early Mars
Introduction: A building body of evidence from recent Mars exploration missions suggests that sulfur chemistry may have played a prominent role in the planet’s early evolution. Although the Martian atmosphere contains virtually no sulfur species at present, both soils and outcrop observed by landed missions have high sulfate abundances [1,2]. The OMEGA hyperspectral imager has now also identifi...

Despite a fainter Sun, the surface of the early Earth was mostly ice-free. Proposed solutions to this so-called ”faint young Sun problem” have usually involved higher amounts of greenhouse gases than present in the modern-day atmosphere. However, geological evidence seemed to indicate that the atmospheric CO2 concentrations during the Archaean and Proterozoic were far too low to keep the surfac...
