It's an accusation that has often been lobbed at Keith's main
area of study: geoengineering
Earth's climate to counteract warming by, for instance, injecting particles into the sky to
reflect sunlight.
However, there is an additional shortcoming due to the fact that the equilibrium temperature is also affected by the ratio
of the
Earth's geometrical cross-section to its surface
area as well as how much is
reflected, the planetary albedo (A).
Using a globe, pinpoint an
area of the
Earth's surface that you believe naturally
reflects more
of the sun's light.
The tour is enhanced by the inclusion
of some «CGH
Earth» hotels, which are harmonious to the local environment with high standards - for example at the Spice Village, Periyar, the fine» 50 - mile» restaurant only uses ingredients from within 50 miles and the colonial style bar
reflects its hill station history, whilst «Coconut Lagoon» is only accessible by boat and the «Eighth Bastion» lies within the Fort Cochin
area.
For example, if the
Earth got cold enough, the encroachment
of snow and ice toward low latitudes (where they have more sunlight to
reflect per unit
area), depending on the meridional temperature gradient, could become a runaway feedback — any little forcing that causes some cooling will cause an expansion
of snow and ice toward lower latitudes sufficient to cause so much cooling that the process never reaches a new equilibrium — until the snow and ice reach the equator from both sides, at which point there is no more
area for snow and ice to expand into.
And as that permanent ice cap grew it would cover an increasingly larger
area and
reflect an increasing amount
of incoming sunlight back to space (less energy in), causing
earth as a whole to cool.
The loss
of large
areas of ice on the surface could accelerate global warming because less
of the sun's energy would be
reflected away from
Earth to begin with (refer back to our discussion
of the greenhouse effect).
Soot, when it falls on snowy
areas such as the Arctic and high mountains, causes the
earth to absorb more sunlight, instead
of reflecting it as snow does.
Since the ocean is 70 %
of the
Earth's
area, the temperature anomaly will
reflect that.
Near the subsolar point (dark blue colors), where the Sun is directly overhead, clouds
reflect more than 1000 Watts
of energy per square meter
of Venus's surface
area, an amount almost as large as the energy that
Earth receives from the Sun.
