Radiative forcing (or climate forcing[2]) is a concept used in climate science to quantify the change in energy balance in Earth's atmosphere. Various factors contribute to this change in energy balance, such as concentrations of greenhouse gases and aerosols, and changes in surface albedo and solar irradiance.
21 lis 2014 · 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 plausible future pathway regarding global emissions of greenhouse gases.
Climate forcing measures the imbalance in the Earth’s energy budget caused by a perturbation of the climate system, for example changes in atmospheric composition driven by human activities. Climate forcing, also known as Radiative Forcing, therefore determines the change in globally-averaged temperature change due to the natural or human ...
4 kwi 2017 · Despite an increase in solar output, the Earth’s climate has apparently remained relatively stable over geological time. Here, the authors compile atmospheric CO2data for the past 420 million ...
6 lut 2024 · If more radiation is entering Earth than leaving—as is happening today—then the atmosphere will warm up. This is called radiative forcing because the difference in energy can force changes in the Earth’s climate. Heat in, heat out. Sunlight is always shining on half of the Earth’s surface.
Short-lived climate forcers (SLCFs) are a set of chemically and physically reactive compounds with atmospheric lifetimes typically shorter than two decades but differing in terms of physiochemical properties and environmental effects.
This chapter assesses the present state of knowledge of Earth’s energy budget: that is, the main flows of energy into and out of the Earth system, and how these energy flows govern the climate response to a radiative forcing.
