Document Summary
The theoretical rate at which the temperature of the air changes with altitude. The temperature change is due to the pressure drop and gas expansion only, and no heat is considered to be exchanged with the surrounding air through convection or mixing. The dry adiabatic lapse rate for air not saturated with water vapor. The presence of soot particles in snow could cause a decrease in the albedo of snow and affect snowmelt. All of earth"s surfaces absorb more solar radiation from an overhead sun. Water reflects <5% radiation from an overhead sun. Water reflects a high fraction of radiation from a low-lying sun. Earth surface average albedo = 10: albedo feedback. The anthropocene is an informal geologic chronological term that serves to mark the evidence and extent of human activities that have had a significant global impact on the earth"s ecosystems. The term was coined recently by ecologist eugene f. stoermer, but has been widely popularized by the nobel.
