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 ...
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."
The American Geophysical Union (AGU) adopted a statement on Climate Change and Greenhouse Gases in 1998. [13] A new statement, adopted by the society in 2003, revised in 2007, and revised and expanded in 2013, [14] affirms that rising levels of greenhouse gases have caused and will continue to cause the global surface temperature to be warmer:
The amount of greenhouse gas emissions from agriculture is significant: The agriculture, forestry and land use sectors contribute between 13% and 21% of global greenhouse gas emissions. [118] Emissions come from direct greenhouse gas emissions (for example from rice production and livestock farming). [ 119 ]
In construction as well, 48% of greenhouse gases is emitted. [1] Some calculations make it as much as 70% of all the energy used when all the factors are taken into account. This energy is mainly for heating and lighting and therefore the aim is to design houses that are well insulated and make the best use of natural light. [2]
The terms greenhouse, glasshouse, and hothouse are often used interchangeably to refer to buildings used for cultivating plants. The specific term used depends on the material and heating system used in the building. Nowadays, greenhouses are more commonly constructed with a variety of materials, such as wood and polyethylene plastic. [2]
Eunice Newton Foote (July 17, 1819 – September 30, 1888) was an American scientist, inventor, and women's rights campaigner.She was the first scientist to confirm that certain gases warm when exposed to sunlight, and that therefore rising carbon dioxide (CO 2) levels could increase atmospheric temperature and affect climate, a phenomenon now referred to as the greenhouse effect.
