Sentences with phrase «sea ice melts exposing»

Not exact matches

As melting sea ice opens up the Arctic to more human activity, the mammals, known as «unicorns of the sea» for their single tusk, may be more exposed to the potentially harmful escape response, scientists say.

Melting sea ice exposes dark ocean, which means that the planet absorbs more solar heat.

The melting of sea ice is exposing more ocean waters in the Arctic, but they are showing a limited ability to dispose of CO2, according to a new study

As a result of atmospheric patterns that both warmed the air and reduced cloud cover as well as increased residual heat in newly exposed ocean waters, such melting helped open the fabled Northwest Passage for the first time [see photo] this summer and presaged tough times for polar bears and other Arctic animals that rely on sea ice to survive, according to the U.S. Geological Survey.

The researchers had expected the ocean to play a bigger role in eroding away the coastline, as it has elsewhere — especially as climate change is causing more Arctic sea ice to melt away, leaving the surface of the water exposed.

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.

Remember for a long time «pingos» were surface land features — odd hills on the flat tundra, in areas that that had been under the ice age ice, then had been underwater as that ice melted and sea level rose, then exposed again during the next ice age.

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?).

But, as ice melts back, as is happening today, the summer sun is absorbed by the darker open sea exposed by the disappearing ice.

As Arctic sea ice melts, more and more of the ocean is exposed to sunlight.

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.

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.

Exposing «Staggering» Ice Sheet Melt Deceptions In recent months, two new papers published in The Cryosphere have provided a condensed summary of the ice - melt and sea - level - rise consequences of global warming for the Arctic regiIce Sheet Melt Deceptions In recent months, two new papers published in The Cryosphere have provided a condensed summary of the ice - melt and sea - level - rise consequences of global warming for the Arctic regMelt Deceptions In recent months, two new papers published in The Cryosphere have provided a condensed summary of the ice - melt and sea - level - rise consequences of global warming for the Arctic regiice - melt and sea - level - rise consequences of global warming for the Arctic regmelt and sea - level - rise consequences of global warming for the Arctic region.

The ice sheet is the focus of scientific research because its fate has huge implications for global sea levels, which are already rising as ice sheets melt and the ocean warms, exposing coastal locations to greater damage from storm surge - related flooding.

As sea ice melts, more water is exposed, which traps more heat.

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.

Winds, for example, play a larger role in determining Antarctic sea ice extent, not only by bringing in warm air to melt ice but, more importantly, by jostling the ice loose, exposing more of the unfrozen ocean.

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.

Record - breaking losses of Arctic sea ice mean that instead of being covered with reflective white ice, the darker ocean water is exposed and can store heat energy, reducing the temperature gradient and causing a feedback loop that ends up melting more ice.

As sea - ice melts, it exposes a much darker ocean surface, which absorbs more radiation — amplifying the warming.

As more and more ice melts, larger expanses of darker sea water are exposed.

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.

This increases the surface area of exposed, dark ocean water, and promotes a self - reinforcing cycle of land and sea ice melting and climate warming.

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.

As the atmosphere and oceans warm, sea - ice melts which exposes a much darker ocean.

When sea ice melts, the dark - coloured ocean surface is exposed.

The Medieval Warm Period melted a lot of Arctic Sea Ice and the large amount of Exposed Arctic Water lead to the massive amount of Arctic Ocean Effect Snow that created the Little Ice Age.
