That GH conjecture is totally wrong:
radiation reaching a planet's surface is not the primary determinant of the surface temperature.
If the Earth's climate system is getting out of hand, don't worry, we can regulate it with sulphur particles in the stratosphere, managing the amount of solar
radiation reaching the planet.
Tackling climate change by reducing the solar
radiation reaching our planet using climate engineering, known also as geoengineering, could result in undesirable effects for the Earth and humankind.
Not exact matches
The scant
radiation that did
reach the
planet was trapped by the atmosphere, resulting in warm, wet periods.
New research suggests that repeated exposure to galactic cosmic rays and other forms of
radiation would be debilitating — astronauts could suffer brain damage or develop leukemia after
reaching the Red
Planet — and ultimately deadly.
Vincent Bourrier at the University of Geneva in Switzerland and his team tracked the UV
radiation that
reaches the
planets around TRAPPIST - 1.
If the material carried by the solar wind
reached a
planet's surface, its
radiation would do severe damage to any life that might exist.
Also during 1992 and 1993, ash and other particles from the volcano created a haze around the
planet and slightly reduced the sunlight
reaching Earth's surface and made the sun's
radiation less direct and more diffuse.
The rest
reaches the
planet's surface and is reflected upward again as a type of slow - moving energy called infrared
radiation.
Enveloping the earth with a layer of sulfate particles would cool the
planet by regulating the amount of solar
radiation reaching the earth's surface.
The ozone layer acts as a shield for the
planet that prevents dangerous
radiation from
reaching the biosphere, where humans, plants, and animals reside.
That greenhouse gases being absent does not effect the one third of solar
radiation being absorbed by clouds Or the surface albedo can jump from 12 % to 30 % Or the greenhouse gases being absent but still have clouds to reflect
radiation Or the IR (not now absorbed) by the clouds will not obey Kirchoff's Law on
reaching the
planet surface And so on.
On all
planets temperatures in any troposphere get hotter as you approach the base of that troposphere, whether or not there is a surface there, whether or not solar
radiation reaches the lower troposphere and quite regardless of whether there is carbon dioxide or water vapour in the
planet's atmosphere.
The ozone layer is important, because it prevents harmful ultraviolet
radiation from
reaching the surface of the
planet.
The report, considerably more cautious, describes geoengineering as one element of a «portfolio of responses» to climate change and examines the prospects of two approaches — removing carbon dioxide from the atmosphere, and enveloping the
planet in a layer of sulfate particles to reduce the amount of solar
radiation reaching the Earth's surface.
Many believe that increased water vapor, solar variations in
radiation and magnetic flux, our relative position in the solar system, the tilt of our
planet's axis, the clearing of our atmosphere of pollutants which allows more sunlight to
reach the ground, or our position in the Milky Way galaxy that affects the amount of
radiation reaching our atmosphere and affecting cloud formation, are also important and are not (and can not be yet) adequately considered in the computer models used by the IPCC consensus.
We'd need to add the Bond albedo into Equation 2.3 (making this a gray body instead of a black body in the process) and so about 10 % of the
radiation that
reaches Venus is actually absorbed by the
planet.
The Sun's
radiation transports, or emits, short - wave electro - magnetic
radiation away and thus avoids «a big bang» --(There may also be back
radiation from
planets etc. provided the radiative forces are strong enough to
reach the Sun) On a smaller scale the same «Energy Transport System» or radiative principles work here on Earth too.
All that happens when you start off with a very cold or a very hot «radiating temperature» relative to the incoming
radiation is that the
planet heats up or cools down until it
reaches its equilibrium.
