No one said that humans are causing that, did they? Why do you link
the two? By coincidence?

Mars isn't relevant to this discussion, Rich. I think we are supposed
to be talking about the Earth.

The only place I believe you can go, in trying to make a link here, is
insolation (or solar effects) as a common denominator. Feel free to
correct me, if that isn't your implication.

If you think so, I'd recommend examining Muscheler et al., 2005, which
you can get here:
: http://www.cgd.ucar.edu/ccr/raimund/publications/Muscheler_et_al_Nature2005.pdf

These new calculations use the annual 14C record measured by Minze
Stuiver, et al. They include the Suess effect (which is the dilution
of 14C in the atmosphere due to the combustion of 14C-free fossil
fuel) and because of its importance during the period from 1850 to
1950, it allowed them to connect the 14C production series to the
instrumental measurements of the galactic cosmic ray flux.

Muscheler has concluded elsewhere:
: http://www.realclimate.org/index.php?p=180

with this comment: "Regardless of any discussion about solar
irradiance in past centuries, the sunspot record and neutron monitor
data (which can be compared with radionuclide records) show that solar
activity has not increased since the 1950s and is therefore unlikely
to be able to explain the recent warming."

In other words, Rich, you need to document your objection. What
exactly are you suggesting and upon what evidence and reasoning are
you basing it?

I've no argument with that.

You are ignorant of the situation, Rich. Your conclusion is flawed.
