Not exact matches

By absorbing heat, aerosols can evaporate nearby cloud droplets — making the cloud less reflective and compounding the heating effect.

Currently, the amount of infrared heat radiated back to space is slightly less than what we absorb from the sun due to the increase in greenhouse gases.

Conversely, when there is less Arctic sea ice, the ocean absorbs more heat from the sun, adding to global warming.

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.

When it does, it becomes less effective at lubricating the engine and absorbing heat.

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.

Greenhouse gases absorb intense emission from the surface and re-emit less intense energy at colder temperatures, resulting in an efficient heat trapping mechanism.

As things heat up, I would therefore expect that hotter air will create less dense air and that said, air expansion would push the jet streams north and south as the tropics get more sunlight and the heat is trapped in the climate system, and absorbed slowly by the oceans.

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.

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.

That heat must be dissipated to space, and CO2 (which does not absorb in the UV or visible range), adds to the emissivity of the stratosphere at the warmed temperature, while adding much less to the absorptivity.

1) Greenhouse gasses absorb infrared radiation in the atmosphere and re-emit much of it back toward the surface, thus warming the planet (less heat escapes; Fourier, 1824).

It is true that this lost solar heating now adds to the LW flux coming from below, but the skin layer only absorbs a tiny fraction of that, so the increase in absorped LW flux from below is less than the decrease in the absorbed SW radiation.

Actually, though, most of the OLR originates from below the tropopause (can get up around 18 km in the tropics, generally lower)-- with a majority of solar radiation absorbed at the surface, a crude approximation can be made that the area emitting to space is less than 2 * (20/6371) * 100 % ~ = 0.628 % more than the area heated by the sun, so the OLR per unit area should be well within about 0.6 % of the value calculated without the Earth's curvature (I'm guessing it would actually be closer to if not less than 0.3 % different).

A second alternative acknowledges an unchanging OLR, but posits that less is now entering the stratosphere in wavelengths absorbable by CO2 because a heated surface is now radiating more IR to space in wavelengths where CO2 does not absorb («window regions»).

And so, the amount of heat absorbed by air is more or less in proportion to the amount of each molecular species in the air.

But it does increase the amount of reradiated earthly heat that the troposphere absorbs, so that the stratosphere gets less heat from below, and cools.

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.

With adequate training they would be aware of the science that all of the radiant heat from the earthâ $ ™ s surface that is going to be absorbed by greenhouse gases gets absorbed close to the ground (half within less than 24 meters) and is carried up by convection currents to where it ultimately gets radiated to space.

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

When more energy, sunlight, is absorbed, less heat leaves the system.

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.

Less ice lowers the ocean's albedo allowing more solar heat to be absorbed.

However, these changes are mostly just causing the oceans to absorb more heat, leaving less for the atmosphere.

Cooler glazing temperatures would indicate that collector heated air is not working its way out to the glazing and warming it, and / or that the glazing was seeing less radiation heating from the absorber screens.

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 farther away from the surface the air moves, the less heat there is to absorb.

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.

The ocean has absorbed less that 20 % of the heat from the air above it.

Meaning twice the CO2 concentration could only absorb ~ 100 % of the energy in 5m instead of 10m, no more or less heat is preserved in the atmosphere, depending on CO2.

The reason, Werner said, is because the loss of snow and ice makes the earth's surface less reflective, meaning solar radiation — or heat — is absorbed in greater amounts by the exposed dark ocean or tundra.

Thermal equilibrium doesn't mean the same temperature, if for example, a gas in getting hotter expands and rises becoming less dense and under less pressure it can move faster, it's using thermal energy to move, there's no energy lost, it's just become something else, or, as temperature relates to kinetic energy not thermal energy then heat capacity comes into play, as water can absorb a huge amount of thermal energy before there's any rise in temperature, or whatever, but if you're equating all «energy» to «heat» as thermal energy then that's a different idea altogether, not all energy is heat.

As the light passes through the atmosphere, there is less and less ultraviolet light to absorb, and so the amount of «ozone heating» decreases (Figure 9).

As the oceans absorb the heat from the sun and store it for a period, less heat coming in means a cooler ocean.

RB, In my book, «a conservatively high figure of 1.0» means that one thinks the actual value is less than 1 (even if only slightly), which implies that heat is absorbed by the ocean (I wouldn't really describe it as a feedback).

In addition, they found that in scenarios where the ocean current slows down due to the addition of heat, the ocean absorbs less of both atmospheric gases and heat, though its ability to absorb heat is more greatly reduced.
