Sentences with phrase «sunlight than the ice»

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

Not exact matches

But it is not clear how common ice might be in the main asteroid belt, because sunlight is expected to quickly vaporise ice on the surfaces of airless bodies that fly closer to the sun than Jupiter.

Polar ice reflects more sunlight back into space than polar oceans or continents, helping to cool the overall climate.

Thick ice reflects incoming sunlight, but the melt ponds can transmit more than 50 % of the light to the waters below, promoting under - ice blooms, he says.

It may also explain why other bodies in the Kuiper belt are unusually bright, the researchers say: Fresh ice is typically much brighter than an ancient stagnant surface on which dust and substances produced by interactions with sunlight or other radiation have built up through the ages.

Ice shelves (the floating front edges of glaciers that extend tens to hundreds of miles offshore) melt more because of contact with ocean water below them than they do because of sunlight.

The dark zones look lower than the light - coloured ridges, perhaps because they absorbed more sunlight, causing ices below them to evaporate and the dark layer to sink down.

Anyone who accepts that sunlight falling on ice free waters which has less reflectivity than sunlight falling on a large ice mass covering those waters and also accepts that this reduction in albedo has a positive feedback effect, leading to further warming, can't help but opt for A or B, it seems to me.

Ice and snow scatter, transmit, and absorb sunlight and radiant heat much differently than water.

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.

During the melt season the albedo of seasonal ice is less than multiyear Seasonal ice absorbs and transmits more sunlight to ocean than multiyear Albedo evolution of seasonal sea ice has 7 phases

The exposed open water caused by the wind divergence may absorb some additional sunlight and melt more ice than usual over the next few weeks (temperature - albedo feedback)[related NASA animation], but given that the sun is well on its way to setting for the winter, I think this effect will be fairly minimal.

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.

The researchers say their data lines up better with the historic climate record than other theories proposed to explain the Little Ice Age, including changes in sunlight and an increase in volcanic activity in the late 16th century.

Since the darker ocean surface absorbs more sunlight than the bright ice, this warms the region even further.

Less - than - average cloudiness allowed more sunlight to reach the ice.

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.

In retrospect, our overall outlook of setting a new record minimum based on the vast amount of FY ice should have been tempered by the fact that the FY ice over the pole should be thicker since it was the first ice to grow last fall and the north pole is also colder than the Eurasian and Alaskan coasts, and during summer this ice is subject to less incident sunlight.

But the Arctic sea ice has hit near - record minimums of sea ice since 2002, meaning the ocean is absorbing more sunlight, and heat, than it used to, leading to more ice melt.

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.

But much stronger albedo effects (a measure of how much sunlight is simply reflected back out into space) might be generated by the high winds of the glacial era, giving 10 °C temperature changes rather than the 1 °C excursion of the Little Ice Age.

There is nothing implausible about dark water absorbing more sunlight energy than ice, and there is nothing implausible about more energy resulting in warmer temperatures.

Open ocean absorbs more energy from sunlight than does ice or snow;

And, in this case, what Dr. Meier is referring to is the fact that the albedo (reflectance) of ice is higher than water so that when the arctic is ice - covered, more sunlight gets reflected and less is absorbed.

An example of a feedback loop is when melting ice turns to water, absorbs more sunlight because water is darker than ice, heats up, and causes more melting.

Snow and ice reflect more sunlight than bare ground, meaning less solar radiation is absorbed by the 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.

Because meltwater is less reflective than ice, the surface of the ice sheet is already absorbing more sunlight — previous research found that the reflectivity of the Greenland ice has dropped by 6 percent in the last decade, according to an Ohio State University release on the new research.
