WebJan 17, 2024 · The total effect of dust interactions on the global energy budget of Earth — the dust effective radiative effect — is −0.2 ± 0.5 W m − 2 (90% confidence interval), … Incoming ultraviolet, visible, and a limited portion of infrared energy (together sometimes called "shortwave radiation") from the Sun drive the Earth's climate system. Some of this incoming radiation is reflected off clouds, some is absorbed by the atmosphere, and some passes through to the Earth's surface. … See more The solar radiation that passes through Earth's atmosphere is either reflected off snow, ice, or other surfaces or is absorbed by the Earth's surface. See more Heat resulting from the absorption of incoming shortwave radiation is emitted as longwave radiation. Radiation from the warmed upper … See more For scientists to understand climate change, they must also determine what drives the changes within the Earth's radiation budget. The … See more Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which heats the lower … See more

Web2009). The current radiative forcing is largely caused by carbon dioxide (CO 2), methane (CH 4) and N 2O. The global warming potential of N 2O is large compared to that of CO 2. As a result, N 2O is the third most important contributor to the current radiative forcing (Forster et al., 2007). AtmosphericconcentrationsofN 2Ohavebeenincreasingas
WebClimate Forcings and Global Warming. Any changes to the Earth’s climate system that affect how much energy enters or leaves the system alters Earth’s radiative equilibrium and can force temperatures to rise or fall. These destabilizing influences are called climate forcings.
