Is Mars melting?
- What I read recently about Mars is about the CO2 ice melting near one
pole is that it was more related to orbital changes, much like the
Milankovtich is correlated to change from solar insOlation
variations. Remember the ice is in a region such that orbital
insOlation variations will produce differences in how much radiation
reaches a specific local.
The more interesting constructs are the problem of an ever lumenous
sun as described by Karl Sagan -- which should mean that Mars should
be getting more radiation -- and be warmer than its deep past. And
indeed there is evidence of a warmer Mars where water flowed. How
could this be?
My view? That when Mars had a liquid core it had a weak EMF that
could direct space EMF toward its magnetic poles and that would lead
to signals that with charge seperations of convection would produce
heat trapping cirrus--just like what occurs on earth--a convection
based amplification creating a global EMF. As the core solidified, so
ended the ability of the EMF to react to changing convection patterns-
-and any biosphere that may have evolved.
There is some hint that life evolved on Mars before its core
solidified. This life was very metalic containing according to the
rock recovered here on earth recently--which makes sense from an EMF
ENHANCEMENT or impedance reduction, or conductivity standpoint, to
feed back hydrology toward that life.
