Re: [asa] Martian ice caps

Yes there are some excellent rebuttals to the ice caps on Mars and
the fluctuations in the sun's out and I will send them to you later.
The sun has been studied in quite some depth, as it is a likely
candidate to explain heating/cooling, however the studies have failed
to show a significant link between solar output and the warming trend.
In addition to the negative evidence for a solar cause, science also
has done excellent job at showing how the recent warming trend is
caused by a significant human component.

While global warming deniers go to quite some extremes to 'disprove'
the obvious, the science supporting human causes global warming is
well established. All they can do is whine about a miniscule
temperature adjustment error caused by using the wrong dataset.

As to Mars, the melting of the polar icecaps is indeed caused by solar
output, not that the sun is warming up but rather the planet. It's
called seasons.
