What is climate forcing quizlet?
climate forcings. things that change global temperatures directly. -greenhouse gases, volcanoes, air pollution, land cover changes, etc. climate feedbacks. things that respond to temperature changes, but also affect temperature.
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.
What is climate forcing and sensitivity?
A climate forcing can be defined as an imposed perturbation of Earth’s energy balance. … The consequences from such forcings are often then expressed as the change in average global temperature, and the conversion factor from forcing to temperature change is the sensitivity of Earth’s climate system.
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.
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.
What is radiative forcing quizlet?
Terms in this set (9) Radiative forcing. The difference between the incoming and outgoing energy. Aerosols. are tiny particles of solid or liquid that are suspended in the atmosphere and act to partially block the sun (Global dimming)
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 the difference between climate forcing and climate feedback?
Forcing denotes an external influence on a characteristic of the climate system. Example: Increased emission from the sun leads to an increase of the temperature. Feedback denotes the reaction of the (climate) system to the forcing which, in return, leads to a change in the forcings.
