It makes sense that the cold / dry air has
less heat capacity, and so is most prone to warming.
Now the ground or skin temperature generally varies more in day to night cycle than air temperature, but this surface temperature has far
less heat capacity than the atmosphere - it's couple inches of matter.
- Now the ground or skin temperature generally varies more in day to night cycle than air temperature, but this surface temperature has far

Not exact matches
The cold water of the deep, however, expands
less for the same input of
heat and has a greater
capacity to store warm water.
The ocean has a much higher
heat capacity than land and thus anomalies tend to vary
less over monthly timescales.

But the atmosphere's
heat capacity (= thermal inertia) is much
less than the oceans.
As an aside, ECS can not be
less than TCR by virtue of the definitions of the terms, and will only equal TCR if the effective
heat capacity of the Earth's surface closely approximates to zero.
The study also contains a cautionary note: if effective
heat capacity should prove to be
less than estimated in the study, or the carbon dioxide degassing timescale proved longer, it could result in temperature overshoots in which initial temperature decreases are reversed when carbon dioxide re-accumulates in the atmosphere.
A heavy ceramic cup, doesn't work as good as thermos but works slightly better than
less heavy cup [more a bit more
heat capacity and more insulation] But if you don't screw on the lid, a thermos works about a good as ceramic cup - preventing evaporation of the hot coffee is large factor.
Water volumetric
heat capacity = 4.186 Jcm - 3 K - 1, Soil = ~ 2.0, Air = 0.001297 Jcm - 3 K - 1 (3227 times
less than water) To everyone: Try preparing your breakfast using a hair dryer: --RRB-
If there's no radiation from the Sun, no
heat capacity in the model planet, no mass big enough to effect pressure changes («real» ideal gases which don't have mass), nothing much is happening because there's no movement, (movement from the play of hot and cold volumes as hot gases rise and cold sink, becoming
less dense and gaining density), but,
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.
In contrast, the oceans lose
heat less rapidly, because of the large
heat capacity of water, their ability to overturn as the surfaces cool and become negatively buoyant, and the movement of ocean currents such as the Gulf Stream and the Kuroshio current.
Due to the much higher
heat capacity of soil relative to air and the thermal insulation provided by vegetation and surface soil layers, seasonal changes in soil temperature deep in the ground are much
less than and lag significantly behind seasonal changes in overlying air temperature.
All biomass, ground and water source
heat pumps and solar thermal plants of 45kWth
capacity or
less will need to be certified under the Microgeneration Certification Scheme (MCS) or equivalent schemes.
[3] Each state has interim targets it must meet beginning in 2020, and the EPA proposed that states use a combination of four «building blocks» to achieve the emissions reductions: (1) improving the efficiency (
heat rate) of existing coal - fired power plants; (2) switching from coal - fired power by increasing the use and
capacity factor, or efficiency, of natural - gas combined - cycle power plants; (3) using
less carbon - intensive generating power, such as renewable energy or nuclear power; and (4) increasing demand - side energy - efficiency measures.
However droughts and land use changes can raise temperatures by lowering
heat capacity which can then raise maximum temperatures with much
LESS heat.
Carbon Dioxide can not store
heat; it has a
heat capacity even
less than oxygen and nitrogen and releases any
heat it absorbs practically instantly.
But the
heat capacity of the atmosphere is so much
less than that of the earth, that any warming must be minimal before it all radiates out to space.
Further, when mixing occurs, the first mixing will be between the micron layer and the mm layer — but we already know a) that in fact the mm layer is actually cooler than the water below it; and b) that the
heat capacity of a layer measured in microns is three orders of magnitude
less than that of one measured in millimeters.
But, although that is expanding, it's still only around 50GW of grid - linked
capacity globally and, by contrast, the perhaps
less glamorous but at present far cheaper technology of solar thermal
heat collection is well ahead.
