Why Venus Is Hotter Than Mercury*
July 2021
Planetary energy
balances claimed to prove that greenhouse gases warm a planet are absolute
nonsense, and a single calculated temperature is meaningless. They
completely ignore things like rotational speed. Some references on
planetary energy balances actually state that they only apply for fast
rotation, but they don’t apply there either. Using a 4th power
law for radiation completely invalidates the calculation and use of a single
average temperature. Rotational speed is the reason that Venus is hotter
than Mercury, not because of it's atmosphere of mostly CO2 as claimed by
climate science. Mercury has a solar irradiance of 9116.4 W/m2 and Venus 2611
with less reflected due to some small atmospheric absorption, compared to
earth and to Mercury, which has no atmosphere. A rotation on Mercury takes 59 days and 243 days on Venus. So
during the (much longer) daytime, Venus receives significantly more energy per unit area
than Mercury, making it hotter and a volcanic planet believed to have a
molten core. The atmosphere of Venus actually mitigates daily high and low
temperatures just like on earth, where it does so to the benefit of all
life, but to some much smaller degree. Co2 does not absorb most of the ir
radiation as you can see in it’s absorption spectrum below (from NIST for
earth at lab conditions and 33.33% co2), and no visible
or uv light, so almost all of the incident radiation reaches the surface.
Venus atmosphere is thought to be about 97.5% co2 and have volcanic clouds
of sulfuric acid near the surface.

discussion of "UHI's
and Droughts", in which the fraudulence of
climate/environmental science, atmospheric spectroscopy, and greenhouse gas
warming theory is proven, and in which the true explanation of global
warming and drought is given by David Cummins and his two papers also given
on this website. |
