An exact calculation using the MODTRAN model, over all wavelengths and including methane and ozone greenhouse gasses, as shown in the plot above, gives, for tropical latitudes, an outgoing flux = 298.645 W/m 2 for current CO 2 levels and = 295.286 W/m 2 after CO 2 doubling, i.e. a radiative forcing of 1.1%, under clear sky conditions, as well ...
English: This diagram shows how the greenhouse effect works. Incoming solar radiation to the Earth equals 341 watts per square meter (Trenberth et al., 2009). Some of the solar radiation is reflected back from the Earth by clouds, the atmosphere, and the Earth's surface (102 watts per square meter). Some of the solar radiation passes through ...
The greenhouse effect on Earth is defined as: "The infrared radiative effect of all infrared absorbing constituents in the atmosphere.Greenhouse gases (GHGs), clouds, and some aerosols absorb terrestrial radiation emitted by the Earth’s surface and elsewhere in the atmosphere."
A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet. [6] Additionally, the levels of carbon dioxide and other greenhouse gases (such as water vapor and methane) are high, and sea surface temperatures (SSTs) range from 28 °C (82.4 °F) in the tropics to 0 °C (32 °F) in the polar regions.

The smallest example is a miniature greenhouse known as a cold frame, typically used at home, whereas large commercial greenhouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a ...
The idealized greenhouse model is based on the fact that certain gases in the Earth's atmosphere, including carbon dioxide and water vapour, are transparent to the high-frequency solar radiation, but are much more opaque to the lower frequency infrared radiation leaving Earth's surface.
Animation is a filmmaking technique whereby still images are manipulated to create moving images.In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film.
A variety of greenhouse gas reduction projects can qualify for offsets and credits depending on the scheme. Some include forestry projects that avoid logging and plant saplings, [ 1 ] [ 2 ] renewable energy projects such as wind farms , biomass energy , biogas digesters , hydroelectric dams , as well as energy efficiency projects.
