At sea level on Earth, sunlight's «radiation pressure» is about 50 million times smaller than atmospheric pressure.

«There are other elements involved, but if size were the only factor, we'd be looking for an asteroid smaller than about 40 feet (12 meters) across,» said Paul Chodas, a senior scientist in the Near - Earth Object Program Office at NASA's Jet Propulsion Laboratory, Pasadena, Calif. «There are hundreds of millions of objects out there in this size range, but they are small and don't reflect a lot of sunlight, so they can be hard to spot.

When snow melts in response to warming, more sunlight can be absorbed at Earth's surface because most surfaces have a lower reflectivity than snow.

As sunlight passes through Earth's atmosphere, air molecules refract the light, scattering blue light more effectively than red, leaving red to fill our planet's shadow.

Some prior research has suggested that carbon dioxide emissions from all lakes on Earth are less than what was found in the Arctic, and future factors could shift the importance of sunlight, noted Lars Tranvik, a Swedish scientist, in an accompanying Science article.

The earth receives more energy from one hour of sunlight than is consumed in one year by the entire planet, but there is currently no way to use this energy because there is no way to conserve all of it.

However, Venus is closer to the sun than Earth and receives far more sunlight.

«We don't really know why it is so much stronger at Venus than Earth,» said Collinson, «but, we think it might have something to do with Venus being closer to the sun, and the ultraviolet sunlight being twice as bright.

Sunlight is a form of renewable energy that is virtually limitless: more solar energy strikes the earth each hour than the entire world uses in a year!

«Jupiter is five times farther from the sun than Earth, and the sunlight that reaches that far out packs 25 times less punch,» said Nybakken.

It is close by (in terms of outer space) and has enough sunlight, although it is colder than Earth, especially at night.

Funny that you neglected to mention that Mars has less than 1 % the atmospheric pressure of Earth, and that Mars gets less than half the amount of sunlight per unit area than Earth does.

The nearly two years» worth of reading and animated discussions that went into this study have convinced me more than ever that the idea of «fixing» the climate by hacking the Earth's reflection of sunlight is wildly, utterly, howlingly barking mad.

Polar amplification is the phenomenon that any change on the impact of sunlight on the Earth, for example through the release of greenhouse gases, tends to have a larger effect on the poles than the equator.

In clear skies at noon with sun at zenith at Earth distance, you have 1000 watts, which is a reduction of 360 watts from TOA of 1360 watts per square meter, which less than 27 % reduction or more than 73 % of sunlight reaches the surface.

The ice normally reflects more heat and sunlight back into space than open ocean or bare ground, so when it is reduced, the Earth gets a small incremental heat flux that will result in an increase in temperatures.

Let the water vapor or some other greenhouse gas be reduced, and the warm earth will be losing more heat than it gains from sunlight.

And Mars thin atmosphere allows more sunlight to hit the surface, and because of Earth comparatively very thick atmosphere, that's why I said that with only visible light it would as cold or much colder than Mars.

It would be a sudden effect and something like removing or blocking the sunlight - but unlike having the sun blocked, the night side of earth cool as rapidly as sunlit side - or night would have the more noticeable than day lite side.

So 60 % reaches Earth surface [affects earth surface in someway], but more than 1/2 of sunlight reaching or affecting earth as first been absorbed, scattered, reflected by atmosphere and clEarth surface [affects earth surface in someway], but more than 1/2 of sunlight reaching or affecting earth as first been absorbed, scattered, reflected by atmosphere and clearth surface in someway], but more than 1/2 of sunlight reaching or affecting earth as first been absorbed, scattered, reflected by atmosphere and clearth as first been absorbed, scattered, reflected by atmosphere and clouds.

It has been noted for several decades that climate models tend to predict that Earth will become more sensitive to CO2 as, for example, polar ice melts, exposing open ocean and land that absorb rather than reflect sunlight.

Although increased vegetation would sequester additional carbon, this would be more - than - offset by the loss of the albedo effect, whereby sunlight bounces off white (snow and ice covered) parts of the Earth.

«Precise measurements of temperature within the ocean confirm that the Earth is absorbing more energy from sunlight than it emits back to space, providing perhaps the strongest evidence to date that rising concentrations of greenhouse gases and other pollutants are the primary cause of the current global warming trend.

To even everything up Venus would have to absorb seven times as much sunlight, and that would make that altitude of Venus a lot hotter than Earth.

Also, I could not find any correctly conducted experiments (tests & measurements) that would somehow prove to me that the warming properties of CO2 (by trapping earth's radiation between the wavelengths 14 - 15 um) are greater than its cooling properties (by deflecting sunlight at various wavelengths between 0 — 5 um).

For this reason, the shell will receive less W / sqm from Earth radiation than is emitted by the surface, because the radiation will spread out by the inverse square law just as sunlight gets less intense the further from the sun you get, and the shell will radiate more to space than back to Earth.

Persisting contrails can spread into extensive cirrus clouds that tend to warm the Earth, because they reflect less sunlight than the amount of heat they trap.

[update] From the realclimate article I mentioned: «In one sense, Venus is rather similar to Earth: it has nearly the same mass as Earth, and while its orbit is somewhat closer to the Sun, that effect is more than made up for by the sunlight reflected from Venus» thick cloud cover.

This would be enough to offset the co2 imbalance and keep temperatures no different than today (approx), but questions remain as to how reduced sunlight would affect the earth, plants and humans in other ways.

For example, they pointed to additional temperature data gathered in the last few years, which have been substantially warmer than any similar string of years in many centuries; to improvements in computer models designed to project future trends; and to better understanding of the influence of other climate - influencing emissions, like particles of sulfates that can cool the earth by reflecting sunlight back into space.

The eccentricity cycle affects how much more sunlight the Earth receives when it is closest to the Sun (perihelion) than when it is furthest from the Sun (aphelion) and also enhances or decreases the effect on sunlight of the other two irregularities.

White roofs are more reflective than green roofs, reflecting roughly three times more sunlight back into the atmosphere and therefore absorbing less sunlight at earth's surface.

They are now quite complex and factor in things like; variable output by the sun, variations in the earth's orbit around the sun, greenhouse gases AND dust from volcanoes, greenhouse gases from decay in wetlands and from agriculture (rice paddies are artificial wetlands), differences in the reflectivity («albedo») of different surfaces (grass reflects more sunlight than forest, and ice much more than open water etc.)... and there are many more.

In China, Russia, and Japan, work is underway to build space - based solar collection stations, where the sunlight is actually eight times stronger than on the earth (because our atmosphere diffuses the sun's rays).

Sunlight, falling on the Earth when it's about 3,000,000 miles closer to the sun in January, is about 7 % more intense than in July.

Uranus is at the extreme end with a tilt of ~ 98 degrees; this would induce a very different structure of solar heating (where at certain times the North or South pole would be receiving most of the sunlight, and allow for a large migration of the solar «hotspot» over the course of one Uranian year); this should drive a different atmospheric circulation than on Earth.
