Sentences with phrase «absorbing dark water»

Heat - reflecting white ice has given way to heat - absorbing dark water; snow has melted ever earlier on surrounding lands; more heat - trapping moisture has entered the atmosphere; and bigger waves and storms have assailed weakening ice.

Not exact matches

Trees perform three major climate functions: They absorb carbon, which they pull from the atmosphere, creating a cooling effect; their dark green leaves absorb light from the sun, heating Earth's surface; and they draw water from the soil, which evaporates into the atmosphere, creating low clouds that reflect the sun's hot rays (a mechanism known as evotranspiration that also leads to cooling).

That widespread melting leaves huge swaths of dark ocean water that absorbs more heat from the sun than the white, reflective sea ice it replaces.

These water - filled divots develop when dark grains of bacteria - specked dust collect on a glacier or ice sheet and absorb heat from the sun.

Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean.

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.

Another positive feedback of global warming is the albedo effect: less white summer ice means more dark open water, which absorbs more heat from the sun.

Because water is darker than permafrost and absorbs more heat, melting can cause even more melting.

As the ice thins and once - white areas turn to dark open waters, solar energy is absorbed rather than reflected back into space.

But when sea ice melts, it exposes the darker surface of the underlying water, which absorbs solar energy.

The underlying logic is sound: as sea ice melts, it exposes darker ocean water, which absorbs more of the sun's heat, causing the water temperatures to increase.

To prevent the water from freezing, you can use dark bowls and leave them in a sunny spot to absorb the heat by day, as well as bowls that are deeper and wider.

• albedo decreases as ice melts (ice is perhaps 80 % reflective, while ocean albedo can be as low as 3.5 %) • increased water vapor in a warmer climate • warmer oceans absorb less carbon dioxide • warmer soils release carbon dioxide and methane • plants in a hotter climate are darker

None of the sea - ice specialists I've interviewed since 2000 on Arctic trends ever predicted a straight - line path to an open - water Arctic, but quite a few have stressed the longstanding idea that as white ice retreats, solar energy that would have been reflected back into space is absorbed by the dark sea, with that heat then melting existing ice and shortening the winter frozen season.

This is of particular concern to scientists because of the albedo effect, where the replacement of highly reflective sea ice with darker open water greatly increases heat absorbed from sunlight.

When bright, white, reflective ice melts to reveal darker ocean water, sunlight that would normally bounce back into space is absorbed instead.

When ice melts it reveals darker Arctic Ocean water, which in turn absorbs more heat from the sun, further heating the region.

It is fueled by a feedback loop: rising global temperatures are melting Arctic sea ice, leaving dark open water that absorbs more solar radiation, and that warms the Arctic even more.

With less sea ice, the refrigerator door is left open - darker open water is exposed, which readily absorbs the Sun's energy in summer, heating the ocean and leading to even more melt.

Now if had bowl of water and sunlight shines thru the water, the «dark light» would be absorbed by the water, yes?

The consequences of this are unfathomable, sun absorbed by dark water will exacerbate the warming.

Trees are not only carbon - sinks, but they also perform two other climate - affecting tasks: they absorb light into their dark leaves — causing a warming effect — and they pull water out of the ground and into the air, creating low clouds that promote cooling.

That unusual extreme warming is called Arctic Amplification that CO2 driven models suggest is the result of absorbing more heat because lost sea ice allows darker ocean waters to absorb more heat.

Breaking apart (even the thin) sea ice sheets and allowing the sun to penetrate the dark water and absorb solar radiation where once all that energy was reflected must surely speed up the ice melt (take a look at the track behind the ship in the doco).

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.

The melting of the Arctic ice cap exposes dark ocean water, which absorbs more of the sun's energy than the reflective ice, raising regional temperatures.

One study in the Proceedings Of The National Academy Of Sciences Of The United States Of America estimates the extra heat absorbed by the dark waters of the Arctic in summer would add the equivalent of another 25 per cent to global greenhouse gas emissions.

The Arctic Ocean is absorbing more of the sun's energy in recent years as white, reflective sea ice melts and darker ocean waters are exposed.

The melting of glaciers such as Jakobshavn Isbræ has also begun to expose rock, soil, and ocean waters, which in turn causes further melting, because darker surfaces absorb more heat.

As sea ice melts, darker ocean water is exposed; the additional energy absorbed by the darker surface then melts more ice, setting in motion a self - reinforcing feedback.

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.

The process was accelerated because dark, open water absorbed more sunlight.

2) We have INCREASING POSITIVE feedback effects from (a) melting tundra, (b) melting melting hydrates in the oceans, (c) lower reflectivity (albedo) of the Arctic itself, not to mention its next door neighbor Greenland, (d) increased fires in northern Asia and North America which will further exacerbate albedo, (e) LESS ICE AREA to reflect sun in the Arctic... and thus allow that nice dark water to absorb more and more sun.

As the ice on the surface of the Arctic Ocean melts away, there is a smaller area of white ice to reflect the Sun's heat back into space and more open, dark water to absorb it.

This development also sets up dangerous climate feedback loops as reflective white snow and ice turn into heat - absorbing dark - blue water.

When that ice melts, huge expanses of darker, open ocean water absorb the heat instead, warming things up.

An ice - free Arctic full of dark water will absorb more heat and change global climate patterns.
