Sentences with phrase «which absorbs more heat»

Melting sea ice reduces reflective ice and increases exposure of the sea surface, which absorbs more heat thus exacerbating the warming affect.

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.

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.

Water absorbs microwaves far more easily than ice does; incomplete thawing will result in uneven cooking and the potential survival of undesirable microorganisms in those parts of the food which have been insufficiently heated.

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

As the climate changes, Southern Ocean upwelling may increase, which could accelerate ice shelf melting, release more carbon into the atmosphere and limit the ocean's ability to absorb heat and carbon dioxide from the atmosphere.

Shivering and trying to warm the body by exercising only contribute to heat loss; the cold water absorbs the heat far more quickly than the body can create it and cools the extremities, which then cool the body's core.

Hyperthermia (hyperpyrexia), in its advanced state referred to as heat stroke or sunstroke, is an acute condition which occurs when the body produces or absorbs more heat than it can dissipate.

We also find heat sloshing around the world's oceans, which absorb 93 quadrillion watts of the sun's energy — a hundred thousand times more power than could be produced by all the power plants in the United States put together.

That water then absorbs solar energy and heats up, which leads to even more ice melt.

This darkens the surface, which subsequently absorbs more of the sun's heat.

There are also concerns that oceans, which currently absorb more than 90 percent of the extra heat being trapped by human greenhouse gas emissions, could eventually release some of that back to the surface, speeding up the surface temperature rise.

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.

Darker asteroids (which both absorb and radiate heat more efficiently) have both hotter hot sides and colder cold sides.

Some foods which contain carotenoids or lycopene (orange vegetables and tomatoes) actually become healthier during the cooking process because the heat breaks down the cell wall and allows the nutrients in the plant to become more bioavailable and easier to absorb by our bodies.

Hence the denser (more molecules) a substance is, the more energy (heat) it needs, which means it absorbs heat faster then a less denser substance like air for example.

The changes seen in the MSU 4 data (as even Roy Spencer has pointed out), are mainly due to ozone depletion (cooling) and volcanic eruptions (which warm the stratopshere because the extra aerosols absorb more heat locally).

These wildfires release soot into the atmosphere, which accelerates the rate of melting of glaciers, snow and ice it lands upon, which can lead to less reflectivity, meaning more of the sun's heat is absorbed, leading to more global warming, which leads to even more wildfires, not to mention greater sea level rise, which is already threatening coastal areas around the world.

Away from the dense network of heat absorbing (daytime) then heat radiating (nighttime) structures which is the Urban Heat Island and above the air with high water vapor content trapped by the valley along the river, not to mention the pall of coal dust over the city, morning low temps were much more like what the natural countryside would experieheat absorbing (daytime) then heat radiating (nighttime) structures which is the Urban Heat Island and above the air with high water vapor content trapped by the valley along the river, not to mention the pall of coal dust over the city, morning low temps were much more like what the natural countryside would experieheat radiating (nighttime) structures which is the Urban Heat Island and above the air with high water vapor content trapped by the valley along the river, not to mention the pall of coal dust over the city, morning low temps were much more like what the natural countryside would experieHeat Island and above the air with high water vapor content trapped by the valley along the river, not to mention the pall of coal dust over the city, morning low temps were much more like what the natural countryside would experience.

CO2 (and some other gases) in the atmosphere are however more opaque to LWIR; they absorb that a chunk of that outgoing radiation and re-radiate it in all directions — so that a fraction less than half is re-radiated downwards; which has the effect of slowing the transfer of heat (by radiation) out of the atmosphere.

* increasing CO2 concentration of the opaque (lower) layer of the troposphere absorbs more LWR, which decreases the heating of the upper layers and eventually produces a cooling.

According to the scientist conducting the study, the soot — which comes from the Chindia belt, as well as the Western world — and which is black, absorbs heat from the sun more readilly than white ice, thereby accelerating the warming and melting of the glaciers even more than the Greenhouse effect.

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?).

The United States delegation even weighed in, urging the authors of the report to explain away the lack of warming using the «leading hypothesis» among scientists that the lower warming is down to more heat being absorbed by the ocean — which has got hotter.»

One could argue that the ocean is warming due to loss of sea ice that allows the ocean to absorb more heat during the summer which carries over into the winter.

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

Snow and ice reflect heat very effectively (which is why patches of snow survive long after temperatures rise above freezing), so if warming leads to less snow, then more heat will be absorbed, which warms the planet further.

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.

In the Arctic, the tipping points identified in the new report, published on Friday, include: growth in vegetation on tundra, which replaces reflective snow and ice with darker vegetation, thus absorbing more heat; higher releases of methane, a potent greenhouse gas, from the tundra as it warms; shifts in snow distribution that warm the ocean, resulting in altered climate patterns as far away as Asia, where the monsoon could be effected; and the collapse of some key Arctic fisheries, with knock - on effects on ocean ecosystems around the globe.»

For instance, the long - term warming effects of CO2 and other greenhouse gases are largely buffered by the ocean, which absorbs more than 90 percent of the excess heat caused by human emissions of CO2 and other greenhouse gases.

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.

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 1998, a warm ocean absorbed less heat — which caused the atmosphere to heat up more.

«Because snow and ice reflect the Sun's heat, this melting causes more heat to be absorbed, which causes more melting, resulting in another feedback loop.»

Both wetland drying and the increased frequency of warm dry summers and associated thunderstorms have led to more large fires in the last ten years than in any decade since record - keeping began in the 1940s.9 In Alaskan tundra, which was too cold and wet to support extensive fires for approximately the last 5,000 years, 105 a single large fire in 2007 released as much carbon to the atmosphere as had been absorbed by the entire circumpolar Arctic tundra during the previous quarter - century.106 Even if climate warming were curtailed by reducing heat - trapping gas (also known as greenhouse gas) emissions (as in the B1 scenario), the annual area burned in Alaska is projected to double by mid-century and to triple by the end of the century, 107 thus fostering increased emissions of heat - trapping gases, higher temperatures, and increased fires.

Pielke seniors thing is that land use changes leadto albedo changes which lead to more heat absorbed, so actually the warming isn't much to do with CO2 and so there isn't much of a problem.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

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.)

To be energy or more properly, heat transferred, the one - way upwelling radiation from the surface absorbed by the air should be reduced by subtraction of the down - welling radiation of the air absorbed by the surface Note that by subtraction of the (about 20 W / m ² in global average) flow surface to cosmos of both terms of GH, GH expression becomes GH = (radiation from the surface absorbed by the air) minus (outgoing longwave radiation from the air) which has absolutely no physical sense!

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 rapid changes underway in the Arctic are partly caused by the disappearance of sea ice, which causes more light and heat to be absorbed at the ocean's surface during sunny months instead of being reflected into space.

But NOAA considers MMTS to be the more accurate, the reason given being that the thin plastic gill structure of the MMTS shielding does not absorb and retain heat, unlike that of CRS, which is housed in a large wooden box, and are better placed to provide circulation.

20 Global Weather Patterns If the Earth warms up significantly, the surface of the oceans will absorb more heat, which may make hurricanes and typhoons more common.

It absorbs solar radiation converting it to heat and then warming the atmosphere, It also dissolve in the oceans lowering the pH (makes them more acidic) which interferes with phytoplankton, fish reproduction the production of coral and mollusk shells.

More likely the oceans on our 70 % water covered world, which absorb heat energy from the sun (for which we have some data), and geothermal energy (for which we have virtually no data), and release it over long periods of time by poorly understood mechanisms that are possibly the real driving force behind climate.

What will happen is that the ocean is expected to stop «helping» us by absorbing as much heat as it does now, which means that more heat will go into the atmosphere.

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.
