Sentences with phrase «exposed absorbs more heat»

The darkness of land and water compared with the reflectiveness of snow and ice means that when the latter melt to reveal the former, the area exposed absorbs more heat from the sun and reflects less of it back into space.

Not exact matches

Melting sea ice exposes dark ocean, which means that the planet absorbs more solar heat.
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.
An example of a positive feedback is Arctic sea ice melting, which exposes the ocean, which absorbs far more energy than the snow and ice did, causing the ocean to heat (or the air to cool?).
Because ice reflects some heat radiation back out into space, when it melts it exposes darker ocean which then absorbs that radiation, leading to more warming.
Melting of arctic sea - ice, antarctic ice shelves, and mountain ice and snow exposes the darker rock, soil, or sea beneath; which then absorb more of the Sun's heat and further warm the Earth.
And every year, the exposed ocean absorbs a little more heat.
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.
Still, they indicate that some areas of the ocean are heating up especially fast, such as the Arctic Ocean — which this year had its lowest winter ice year on record — and is absorbing much more solar energy as melting ice cover exposes new dark surfaces.
In the polar regions, where few such storms occur, heating by greenhouse gases remains at the surface, and is exacerbated by the melting of bright sea ice that exposes more of the dark ocean surface and causes more sunlight to be absorbed.
Now bare water is exposed to the sun's rays, and absorbs more light than did the previous ice cover; so the planet heats up a little more.
The retreat exposes soil, rock, and ocean surfaces, which absorb light and heat, causing further melting.10, 11 (See Jakobshavn Isbræ and Helheim glacier hotspots for more information on albedo.)
All this melting has begun to expose rock and soils (and ocean in areas where sea ice has melted), which in turn causes further melting, because darker surfaces absorb more heat.
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 the area warms in response to manmade greenhouse gases, melting ice and snow allow exposed land and water to absorb more of the Sun's heat, which melts more ice and snow, and so on.
We could start with an ice - albedo positive feedback with some melting snow exposing dark ground that absorbs heat and makes more snow melt.
Re: Sam Urbinto (# 180), The example of snow melting, exposing more ground, absorbing more heat is an example of a system component's accellerating response to insolation, with no feedback (i.e. change in the power flux of the input) whatsover.
With less snow and ice to reflect the sun's rays and with more exposed ocean to absorb heat, a vicious cycle leads to even warmer temperatures.
But as the exposed ocean absorbs more sunlight, the region will keep heating up.
To make matters worse, the earlier loss of snow in the region could trigger the dreaded albedo effect — basically a positive feedback loop in which melting snow exposes the ground, leading to more heat being absorbed and, eventually, more warming.
