atmosphere is so
thin.
A study examined three different factors: warmer -
than - usual surface
atmosphere conditions (related to global warming); sea - ice
thinning prior to the melting season (also related to global warming); and an August storm that passed over the Arctic, stirring up the ocean, fracturing the sea ice and sending it southward to warmer climes.

than a third of the mass of Earth.
The authors propose that the water detected in the RSL is sucked from the
thin Martian
atmosphere, rather
than supplied by underground reserves.
Those rocks, decelerating less
than the surrounding ice as the comet passes through Mars»
thin atmosphere, strike the ground an instant earlier
than the ice and create the crater.
In contrast, super-Earths with a similar concentration but larger absolute amount of radioactive heat sources (i.e., uranium and thorium)
than Earth would produce more internal heat, more vigorous mantle convection, and faster plate tectonic action involving
thinner plates, which may promote planetary habitability with lower mountain ranges but higher volcanic activity and an
atmosphere with a greater relative composition of volcanic and lighter gases (Sasselov and Valencia, Scientific American, August 2010; Valencia and O'Connell, 2009; and Valencia et al, 2007).
With the
thin air and compressed
atmosphere on the plane, it turned out the Viagra started working much quicker
than he expected.
There's little doubt that Night at the Museum: Battle of the Smithsonian ultimately fares slightly worse
than its uneven yet agreeable predecessor, with the almost pervasively juvenile
atmosphere and hopelessly
thin storyline resulting in a myriad of lulls within the movie's ongoing narrative.
(PS a skin temperature can be lower
than the brightness temperature of the OLR because a very
thin layer at the top of the
atmosphere will absorb a tiny fraction of OLR, thus barely affecting OLR, but must in equilibrium emit that same amount of energy both upwards and downwards; if it were as warm as the brightness temperature of the OLR then it would emit twice what it absorbs and thus cool.
Thin ice and open water generate new ice faster
than thick ice, as the heat from the ocean below is able to escape more easily to the
atmosphere.
Mars is further from the sun
than earth, and only receives about half as much solar energy, and its
atmosphere is so
thin there's nothing to really heat up.
simply put — planets with thick (denser)
atmospheres are warmer
than ones with
thinner atmospheres — independent of the constituent gases in the
atmosphere!
And planet Earth is not hundreds of degrees, despite our molten core being more
than 1000 degrees and our
thin atmosphere, call the thermosphere being hundreds of degrees.
On this planet, the
atmosphere is about 100 times
thinner than Earth's — a very different situation from the ancient past, when geological evidence shows that water used to flow on the surface more
than 4.5 billion years ago.
Add to that the
thinning of 14C in the
atmosphere by the release of 14C free fossil fuels and
thinning by the increase of total CO2 mass, and it is clear that the 14C as tracer is going down much faster
than what an extra 12C / 13C mass does.
And Mars
thin atmosphere allows more sunlight to hit the surface, and because of Earth comparatively very thick
atmosphere, that's why I said that with only visible light it would as cold or much colder
than Mars.
Mars:
thin atmosphere (albeit composed of 95 % CO2)-- > no «greenhouse effect» Earth: denser

Rather
than having a
thin atmosphere and solid - and - liquid surface like Earth, Saturn is a gas giant whose deep
atmosphere is layered with multiple cloud decks at high altitudes.
CO2 is a radiative gas that absorbs a
thin slice of out - going radiation and, since re-emission time is magnitudes more
than collision time, thermalises that energy to the remaining 99.96 % of the
atmosphere.
Furthermore, for
thin air high in the
atmosphere to «fall» down to the ground, you would need to create a region with near vacuum conditions (people would suffocate and «explode» because of lowered pressure, rather
than freeze to death).
For as new heat is added, far more goes into the oceans
than into the
thin atmosphere.
The diurnal and seasonal variations add, however, to the circulation but can not lead to more net transfer of heat to upper altitudes
than the optically
thin atmosphere can lose by net IR (emission - absorption).
Dr. Kristin L. Gates of the Global Aerospace Corporation (GAC) will present the idea of GOLD, a patented system that uses an ultra
thin balloon envelope —

atmosphere and burn up.
In such units, an
atmosphere with the present amount of CO2 is optically thick where the absorption coefficient is one or greater, and optically
thin where the absorption coefficient is less
than one.
