Not exact matches
Like all substances, all gases
absorb heat by conduction and / or convection (and some by IR as well)...
otherwise they could never get
heated!
The upper layers of the earth's oceans are a lead suspect for
absorbing more
heat that
otherwise would remain in the atmosphere.
As the earth's natural air conditioner, white sea ice moderates solar
heating by increasing the reflectivity of Earth's surface and decreasing the amount of
heat that would
otherwise by
absorbed by darker ice - free Arctic seas.
I'd go very simple: Greenhouse gases in the atmosphere
absorb heat radiation that would
otherwise be lost to space, raising the average temperature of the system.
More recently, scientists have been surprised to learn that black carbon — not only from biomass fires but from dirty diesel engines and other sources — is a far larger contributor to global warming than previously suspected: The dark particles
absorb and retain
heat close to the Earth's surface that might
otherwise be reflected.
The rate at which this conversion takes places is crucial, as
otherwise it may turn out that the CO ₂ molecule simply re-radiates at one of its characteristic frequencies (such as the one that it
absorbed in the first place) befor the energy has time to appear as
heat.
So if the oceans cant
absorb IR to get their
heat and if they cant
absorb heat from the air (which is actually a good thing
otherwise it would be snowball earth time) then where oh where did all the
heat go?
Atmospheric carbon dioxide is the most voluminous of the so - called greenhouse gases that
absorb heat radiated from the ground and then radiate some of it back to the Earth's surface, keeping the Earth warmer than it
otherwise would be.
Not to mention, why do skeptics continue to ignore, dismiss, or simply «argue with» by any means possible, the far more important fact that most of the increased
absorbed heat energy is going into warming the oceans, not the atmosphere (thus keeping the ambient air temp rise from registering as high as it
otherwise would, and impacting FUTURE climate far more).
It also
absorbs and retains carbon that might
otherwise be
heating up the atmosphere.
He arrives at his inflated value by conflating the radiative surface warming from GHG's and clouds with the return of latent
heat, thermals and solar energy
absorbed by clouds and subsequently sent to the surface which are
otherwise already accounted for by the net surface temperature and its consequential BB radiation.
