What is a climate forcing agent quizlet?
a climate forcing is a perturbation in the climate system that creates a change in energy. Positive Radiative Forcing. Most greenhouse gases like, CO2 is a positive forcing.
What are examples of climate forcing?
Volcanic eruptions, changes in the Sun’s radiative output, and the mostly anthropogenic changes in greenhouse gases, tropospheric aerosols, and land use are the main climate forcings for surface temperatures over the last 2,000 years.
Which is the best description of a climate forcing?
A climate forcing is an energy imbalance imposed on the climate system either externally or by human activities. Examples include changes in solar energy output, volcanic emissions, deliberate land modification, or anthropogenic emissions of greenhouse gases, aerosols, and their precursors.
Which process plays the most important role in the greenhouse effect quizlet?
Which process plays the most important role in the greenhouse effect? Energy radiated by the earth is absorbed by the atmosphere. atmospheric gases trap and return infrared radiation radiated by Earth. What is the effect of the absorption of infrared energy on matter?
What is radiative forcing describe some warming and cooling forcing agents quizlet?
Radiative Forcing: is the influence that a factor has on the energy balance of the atmosphere-ocean-land systemCooling Force Agents: clouds reflect radiation into space causing albedo, aerosols that cancel out some of the warming from greenhouse gases, and the cryosphere (ice) reflects sunlight.
How does climate forcing differ from climate response?
Climate scientists define climate forcing as an imbalance in radiation at the top of the Earth’s atmosphere. … We define climate response as the change in globally averaged surface temperature that results from climate forcing due to radiation imbalance at the top of the atmosphere.
What is internal climate forcing?
Internal forcing operates from within the climate system, for example the change in the global energy balance due to changes in the composition of the atmosphere. … Physical changes within the Sun may alter the intensity or character of the incoming solar energy.
Which of the following is an example of external forcing?
Examples of natural external forcing include solar variability and volcanic eruptions. Examples of anthropogenic forcing are from changing concentrations of greenhouse gases and aerosols, and land cover use produced by human activities.
