List of climate forcing agents
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. Each scenario is based on a … Meer weergeven Another way to refer to climate forcings is to call them climate drivers. Natural climate drivers include changes in the sun’s energy output, regular changes in Earth’s orbital cycle, and large volcanic eruptions that … Meer weergeven WebClimate change is defined as the warming of the climate system due to human activities. Emission of greenhouse gases (GHGs), which cause an increase in radiative forcing, is the main contributor, and the only climate forcing agent currently considered in life cycle impact assessment (LCIA) methodologies. The direct consequence is an increase in ...
