    Effects on the global temperature of large increases in carbon dioxide and aerosol densities in the atmosphere of Earth have been computed. It is found that, although the addition of carbon dioxide in the atmosphere does increase the surface temperature, the rate of temperature increase diminishes with increasing carbon dioxide in the atmosphere. For aerosols, however, the net effect of increase in density is to reduce the surface temperature of Earth. Because of the exponential dependence of the backscattering, the rate of temperature decrease is augmented with increasing aerosol content. An increase by only a factor of 4 in global aerosol background concentration may be sufficient to reduce the surface temperature by as much as 3.5 ° K. If sustained over a period of several years, such a temperature decrease over the whole globe is believed to be sufficient to trigger an ice age.

    The CO2 makes the earth work just like a green house it lets the heat in from the sun but traps it in. Scientist say they can make mars livable over hundreds of years by emiting CO2 into the atmosphere to raise the planetary temperature.

    CO2 in the international absorbs 8% of the IR. there is not any magic or technology that could improve that. The CO2 on earth absorbs lots of the radiation that it may from the floor from the 1st 10 meters it relatively is what greenhouse warming is. relatively all something is absorbed interior the 1st few hundred meters. it relatively is easy and you're unlikely to extend it severely. Water, it relatively is countless situations greater focused on the floor additionally has a lots wider absorbance band. while the air is heated from CO2, the ambience radiates the warmth like the floor and eight p.c. of the unique 8 p.c. gets absorbed lower back. 0.5 of that warmth radiated that isn't absorbed is lost to area and something will improve the warming of the floor. greater CO2 does not soak up greater by using fact one hundred% is already absorbed. the gap is shortened some the place it absorbs to extinction yet it relatively is mitigated by using convection. climate works on comments mechanisms and not the ridiculously simplistic way pronounced by using alarmists with an time table. Venus has approximately one hundred situations as thick of an environment. i've got faith that broadens the bandwidth yet lots greater importantly, there are different gases like H2SO4 that soak up seen gentle and convert it to warmth. Then CO2 can catch that warmth by using fact the bands are opaque in some inches interior the frequencies they soak up. that isn't greenhouse warming. it relatively is the ambience quickly absorbing seen gentle frequencies. they are additionally nearer to the sunlight so as that they get lots greater warming. the floor is fairly skinny and contemporary and "geothermal" probably bills for lots of it. there is an insulating property of all rely. while it relatively is one hundred situations thicker, it insulates lots greater effective. All warmth does not circulate by using radiation. It additionally transfers by using conduction and convection. there is not any assessment between Earth and Venus. we've not got Sulfuric acid clouds.
