WHERE'S THE HEAT?
From Junkscience, 16 January 2001
http://www.junkscience.com Now even models suggest that warmer ocean temperatures induce more
evaporation, leading to more cloud formation and subsequent surface cooling!
This is one of the great problems with the enhanced greenhouse hypothesis -
the so-called positive feedback of increased evaporation (water vapor is the
major greenhouse gas) inevitably results in the negative feedback of
increased albedo (reflection of solar radiation) due to increased cloud
formation, damping rather than enhancing the negligible warming influence
possible from anthropogenic atmospheric CO2 addition. Parenthetically, this
piece alludes to a global decadal trend of +0.1°C since 1950 although such a
figure is extremely dubious. The contiguous US composite record makes a fair
to muddling proxy for global temperature trends over the period, so judge
for yourself. Hard to pick a decadal trend of +0.1°C since 1950 isn't it?
These fanciful figures are enabled by using estimates of proxies for air
temperature. Over 7-10ths of the Earth's surface is composed of the oceans,
this means using ocean 'surface' temperatures (everything from 'bucket on a
rope' to ships' engine coolant water manifold temperatures) as a proxy for
air temperature. If you think this might be a less-than-reliable means of
establishing Earth temperature trends you are not alone.
The recurring cycle seems to me.
