WebAbstract We describe the historical evolution of the conceptualization, formulation, quantification, application, and utilization of “radiative forcing” (RF) of Earth’s climate. Basic theories of shortwave and longwave radiation were developed through the nineteenth and twentieth centuries and established the analytical framework for defining and quantifying … Human-caused, or anthropogenic climate drivers include emissions of heat-trapping gases (also known as greenhouse gases) and changes in land use that make land reflect more or less sunlight energy. Since 1750, human-caused climate drivers have been increasing, and their effect dominates all … Meer weergeven Earth is continually bathed in energy from the sun. A portion of the energy that arrives at Earth is reflected back into space, another portion is absorbed directly by the … Meer weergeven In accordance with the basic laws of thermodynamics, as Earth absorbs energy from the sun, it must eventually emit an equal amount of energy to space. The difference between incoming and outgoing radiation is … Meer weergeven Climate scientists have defined four possible scenarios for the future that they use as consistent inputs for calculating climate in the future.
