Sentences with phrase «reflect less heat»

But these cooler streets also reflect less heat onto buildings, saving on air - conditioning costs and reducing the effects of climate change.

That's because the dwindling ice reflects less heat into space, causing it to warm up faster and melt away.

Not exact matches

With less ice, the Arctic reflected less of the sun's energy out into space, leading to a surplus of heat there.

Researchers say the ice thinning may accelerate because as it melts, it reflects less sunlight, which heats the surrounding waters even more.

Storm clouds play a big role in keeping the planet cool by reflecting heat back into space — but they're not as effective farther north or south, where there's less solar radiation anyway.

The interesting part is that more clouds in summer as well as less clouds in winter both act as negative feedbacks: less warming in summer with more clouds reflecting the sunlight and more cooling in winter from less clouds allowing more heat to escape to space.

Debunking: According to this theory, cosmic rays are responsible for cloud cover — fewer cosmic rays means fewer clouds and less cooling in the summer (clouds reflect the energy) and more heating in the winter (as clouds hold heat in).

These films reflect and / or absorb some of the solar energy, resulting in less heat gain to the house.

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.

The water vapor cooled the Earth, the snow cooled the atmosphere with resulting increase in surface albedo which does reflect radiative heat, meaning the Earth gets less warm, not colder because of it.

As we lose ice, less heat gets reflected and more heat gets absorbed and ice melts even more.

Light surfaces reflect more light away and absorb less heat.

This means that less energy is used up evaporating water, that less of the Sun's energy is reflected and that more heat is stored by buildings and the ground in urban than in rural areas.

But with several factors combining to increase temperatures in Greenland and reduce the reflectivity of the snow and ice cover, the ice sheet is becoming less efficient at reflecting that heat energy, and as a consequence melt seasons are becoming more severe.

Warmer winters (if they have lots of clouds... in winter thick clouds actually warm since there is less daylight and there cooling effect is now reversed to warming by retaining the heat... reflecting more IR than carbon dioxide can do, depending upon the type of cloud).

And at the surface a unknown but large percentage of indirect sunlight energy and direct sunlight energy is scatter, reflected, and re-radiate and about 1/2 or less of this energy is absorbed and thereby heats the surface.

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.

I believe the IPCC claim that high cloud is a positive feed back (traps heat) and low cloud is a negative feed back (reflects sunlight) and following IPCC simple logic we find that AGW will cause less rain and more droughts sooooooooooooooooo if we have less rain we have less low clouds therefore we must have more high cloud.

Imbalance = incoming less reflected solar radiant energy minus the heat energy from surface and atmosphere escaping to space.]

The decrease in light - colored ice reflects less incoming solar energy back into space and can heat the troposphere.

Persisting contrails can spread into extensive cirrus clouds that tend to warm the Earth, because they reflect less sunlight than the amount of heat they trap.

An increase of solar radiation will lead to a rising temperature, to an extent depending on the amount of ice on the surface; an ice cover will reflect much of the extra radiation away, causing less heating, until eventually the heating is sufficient to melt the ice.

By reflecting the sun's rays back to space, these cool materials also release less heat into the atmosphere, thus cooling the planet and offsetting the warming effects of substantial amounts of greenhouse gas emissions.

The hypothesis being that the cosmic rays create cloud condensation nuclei which create lower level clouds which reflect incoming solar insolation, thereby causing less heating to the Earth / oceans, and therefore net cooling for as long as the condition lasts.

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.

So, because ponded ice reflects less of the solar radiation, there is more heat available to melt the surface of the ice,» said Daniel Feltham, a researcher at the Center for Polar Observation and Modeling at the University College London, and co-author of the study, in an email.

This black carbon changes the albedo of the ice, causing it to reflect less sunlight and absorb more heat.

The design's colour palette of striking blues and light hues reflects more sunlight and absorbs less heat — improving the look of these popular pedestrian plazas while making them more comfortable places to sit.

When asked if «now is a good or bad time to buy a home in your community,» British Columbians were slightly less positive about buying than a year ago while Saskatchewan and Alberta were the only two provinces where a majority gave a negative response (60 and 59 per cent respectively), reflecting the heated housing markets in those two provinces.
