But Stone predicts that because species in hot environments evolve body shapes that
radiate heat better, climate change will cause humans to grow taller and slimmer.
Not exact matches
The team calculated that those hydrocarbon clumps could absorb
heat from the sun as
well as from gases in the atmosphere and
radiate it back into space.

Good heat dissipation, High Temperature Resistance, Rust Resistance, Bump Resistance, vivid color 5 * Protect the eye - sight, no strobe, no
radiate, no light pollution 6 * Easy to Instal, Simple to fit, Just plug in and play.
Their body's are much
better at insulating them from the cold than
radiating excess
heat away.
F1 2016 has a variety of nice graphical touches including
heat haze from the rear of your car and opposing cars to realistically create the sensation of
heat radiating from a car running at high temperatures, while lighting, shadows and textures all look as
good as ever.
(2) In the stratosphere, CO2, being a
good IR emitter,
radiates to space the
heat energy it gains from collisions with other molecules.
Well, the air would cool down exclusively by
radiating heat radiation into space.
Ideally the zero point would be modulated by ocean
heat content and / or ssts, since it is the comparison between energy into the oceans vs. energy
radiated back out that determines warming or cooling, but we don't have much historical ohc or sst data so a fixed zero point would seem to be the
best that can be done.
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.
Also, if it's a
good reflector,
heat will have to build up more inside than if it weren't, but not because it's
radiating energy.
That means that the Earth is
good at
radiating away
heat from its surface whether or not low clouds are present.
One underemphasized benefit of having
good insulation inside your walls is that it makes the room surface of the wall warmer so it
radiates more
heat back to the people in the room.
Kate's phrasing might be
better put as that the effect of greenhouse gases means «more
heat is re-
radiated within the lower atmosphere making it warmer, and more is
radiated out of the stratosphere making it cooler» or something like that.
Hmm, when the temperature increases a bit, this causes an increase in
radiated energy of a bit plus a bit more in a way that's dependent on the starting temperature but not so much that you would really notice, and the increase could get funded by the change in conducted
heat through the bulk so long as we change the temperature of the other side of the bulk by at least,
well, let's say a lot more, or at least a little more than when we did the experiment last time..»
My point was simply that
heat is energy, and if you've gone to the trouble of collecting it, you might as
well use it rather than
radiate it back out into the environment.
Considerable
heat is then transferred by natural convection from the lower reaches to the upper reaches clearly
radiating in three dimensions as
well before finally leaving for space.
So, the «back radiation» from the greenhouse gas can only
heat the surface (at
best) to less than the surface
radiating temperature which «warmed» the greenhouse gas.
Because they are reflective, they also prevent energy in the form of
heat from being
radiated back into atmosphere, thus helping to cool the city as
well as the planet by reducing the amount of energy trapped by the greenhouse effect.
After a few infrared measurements on summer nights showed that the amount of
heat being
radiated from the atmosphere was much less than some climate models predicted, he began an intensive study resulting in his own computer simulations based on available atmospheric data and
well - known laws of infrared physics.
Okay, I'm sure the carbon monoxide was a simple mistake, but repeating that everything
radiates all over the place, although uncontroversial, doesn't make a
good case for «
heating».
Well, as davidmhoffer (who I believe is the author of the quote you reproduce) says in the quote itself, ``... it [the igloo inner wall] does absorb
heat from you [the living, breathing, 98.6 ºF person in the igloo] and some of it is conducted through the wall to the outside of the igloo, but, BUT... some is
radiated back to you, the person in the igloo.
«Those with fireplaces and wood burning stoves will also benefit from
better heat distribution, provided the fan is correctly positioned to effectively circulate the
heat radiated or convected by the stove or fireplace.
