Not exact matches

There are more, however, including the amount of sunlight an ice sheet is able to reflect; the larger an ice sheet, the more sunlight is reflected, but the smaller an ice sheet, the more ocean there is surrounding the ice sheet to absorb the sunlight which in turn heats up the surrounding waters increasing the melt which decreases the size of the ice sheet which in turn... and so goes the cycle.

A possible cause for the accelerated Arctic warming is the melting of the region's sea ice, which reduces the icy, bright area that can reflect sunlight back out into space, resulting in more solar radiation being absorbed by the dark Arctic waters.

The darkest blue indicates deeper water, but it's also this shade for another reason: the rich blue hue comes from dye added to speed up the rate at which the water absorbs sunlight and warmth, aiding evaporation.

Which molecules are found in the atmosphere on aerosols will determine whether they absorb or reflect sunlight, affecting the temperature of the planet.

Grasses, for instance, develop thicker leaves, which are able to utilize the direct sunlight in the upper layer of a meadow while clover species sprout larger but thinner leaves to absorb the weaker light close to the ground more effectively.

Warmer temperatures melt the Arctic ice and exposes water, which absorbs more sunlight than ice.

Other cooling strategies include urban trees, which provide shade, and reflective roofs and walls, which absorb less sunlight.

Scientists have in the past focused on above - ground characteristics, primarily leaf traits and the efficiency with which plants absorb sunlight for photosynthesis, he said.

Photovoltaic cells, which absorb photons from sunlight and convert them to electricity, operate with only 20 percent efficiency.

Carbon nanotubes — extremely efficient absorbers of sunlight, which convert nearly the entire solar spectrum into heat — take care of that step.

In addition, they must have been able to resist the biologically destructive ultraviolet radiation in sunlight, which was not absorbed by a layer of ozone as it is now.

The formation of binary minor planets, tumbling action, and period change are most likely due to the YORP effect, which is a thermal process where absorbed sunlight, re-radiated as heat, can affect the minor planet's rotation period and even spin axis orientation.

The Arctic is warming more than twice as fast as the rest of the planet, because as ice melts at the top of the world, there is less of it to reflect sunlight back into space, so more of it is absorbed by ocean waters; more absorbed sunlight means even warmer temperatures, which means more ice melt a circular process known as Arctic amplification.

If crop leaves are exposed to direct sunlight, they will absorb more of it than they can use, which sometimes bleaches the leaves.

Your body absorbs sunlight using cholesterol, which helps convert sunlight into a form of vitamin D that your body can use.

Through photosynthesis, phytoplankton absorbs sunlight, which it stores in sugars it makes from CO2 and water.

The screens absorb sunlight, unlike like LCD screens, which create glare in sunlight.

We all know that black occurs in the absence of light and black is actually the absorption of all color which is why we wear black on cold days to absorb as much sunlight and heat as possible and white (which reflects light and heat) on hot days.

In this case, the temperature at which this would happen is considerably colder (depending on the fraction of sunlight that is reflected and not absorbed) at about 255K... pretty chilly.

The Army says that the geometry of the solar cells allows them to absorb the same rate of sunlight at any angle, which means that they don't need sophisticated sun tracking systems to generate the maximum amount of energy.

If something triggers a cool spell, such as an orbital variation reducing incident sunlight, then water freezes at the poles, which increases the Earth's albedo, while the cooler oceans absorb more CO2, reducing the greenhouse effect.

As a result, the planet as a whole is becoming less reflective and absorbing more sunlight, which is accelerating global warming.

AGWSF's basic fictional meme here is «all electromagnetic energy from the Sun is the same and all create heat on being absorbed» — this is the meme you are repeating in your «Without sunlight adding energy which converted into heat».

By melting sea ice, warming in the Arctic regions allows more sunlight to be absorbed by the ocean which leads to yet more warming.

Additionally, the less sea ice covers the surface of the ocean, the more sunlight is absorbed by the water, which scientists warn could accelerate the Arctic's warming.

It is easy to see why this feedback amplifies the climate change, because reduction of ice sheet size due to warming exposes a darker surface, which absorbs more sunlight, thus causing more warming.

Or it is perhaps interesting that CO2 absorbs near - IR, but energy of sunlight which absorbed and it emits energy is far - IR.

Global warming has a larger affect in polar areas, as the loss of snow and ice leads to more open water, which absorbs more sunlight and warmth.

Which one absorbed more sunlight?

Human emissions are quite different in composition as some also contain brown / black soot which may absorb more sunlight and thus may have more a warming than a cooling effect (especially over India).

Unlike sunlight which penetrates to many tens of meters instantaneously the mid infrared from the atmosphere is absorbed by the top few microns.

On the other hand, satellite - observed changes in absorbed sunlight and emitted heat in the tropics over the period 1985 - 2000, which appear to have caused a strengthening of the tropical atmospheric circulation, could in principle be either anthropogenic or natural in origin.

We know that more open water will put more water vapor in the air, and increase the sunlight absorbed each summer, both of which will lead to yet more warming.

The wind patterns may have changed due to a combination of the current Pacific Decadal Oscillation which has now started changing, and the ozone hole allowing more sunlight to reach the surface rather than being absorbed in the stratosphere; the extra energy from this may have accelerated the winds.

Over the last century, tiny airborne particles called aerosols, which cool the climate by absorbing and reflecting sunlight, have largely cancelled out the effects of GHG emissions on tropical storm intensity, according to a new scientific review paper published in Science journal.

It absorbs 1 / 7th as much IR, heat energy, from sunlight as water vapor which has 188 times as many molecules capturing 1200 times as much heat making 99.9 % of all «global warming.»

They merely trigger the condensation of water vapour (which saturates very easily in low pressure air) into cloud droplets which reflect back sunlight to space, rather than absorbing infrared as water vapour does.

Basically, Dr Ferenc Miskolczi's life as a NASA climate research scientist was made hell because he discovered that the extra water vapour being evaporated is not having a positive - feedback (increasing the CO2 warming effect by absorbing more infrared from the sun), instead it is going into increased cloud cover, which reflects incoming sunlight back to space.

Where clouds are absent, darker surfaces like the ocean or vegetated land absorb heat, but where clouds occur their white tops reflect incoming sunlight away, which can cause a cooling effect on Earth's surface.

Then the ground would absorb more sunlight, which would warm the air, which would melt still more snow: a vicious feedback cycle.
