Understanding how clouds respond to anthropogenic-induced perturbations of our planet's atmosphere is of paramount importance in determining the impact of the ongoing rise in the air's CO2 content on global climate; for as Charlson et al. (2001) have noted, "man-made aerosols have a strong influence on cloud albedo, with a global mean forcing estimated to be of the same order (but opposite in sign) as that of greenhouse gases." Thus, this summary presents a brief review of a number of scientific papers that address this crucial issue.
There are a number of ways in which the activities of humanity are believed to influence earth's climate; and many of these phenomena tend to cool the globe, primarily by enhancing its albedo or reflectance of incoming solar radiation.
Results of several empirical studies led Charlson et al. to conclude that the anthropogenic impetus for cooling "may be even larger than anticipated."
It would appear the surface temperature record on which the world's climate alarmists so long relied, i.e., the infamous hockey stick" reconstruction, was either bogus or that the warming, if real, was due to something quite different from anthropogenic forcing.
In light of these many observations, therefore, it would appear that there is a plethora of natural and anthropogenic-induced negative feedbacks to purported global warming that are more than capable of maintaining the climate of the globe within a temperature range conducive to the continued well-being of all forms of life currently found upon the face of the earth ... and in the sea, and in the soil, and in the air.
