WebbThings that change the balance between incoming and outgoing energy in the climate system are called forcings. Natural forcings include volcanic eruptions. Manmade forcings include air pollution and greenhouse gases. A climate forcing, such as greenhouse gas increases, may trigger feedbacks like the loss of sunlight-reflecting ice. WebbRadiative forcing is the difference between incoming solar radiation and outgoing terrestrial radiation. This power, and thus the difference, is measured in watts per meter squared. Radiative forcing is considered instantaneous if stratospheric temperature changes aren't accounted for. [1] Webb14 apr. 2024 · Significant leaps in understanding volcanic eruptions and their consequences often occur during and shortly after well-observed eruptions.
