Stan,

I did read the article as one of many whilst googling the subject. I
do apologise
for the link, it just happened to be the last (and most recent) that I
read.
There are several other items thrown up by google, indeed one from
NASA
which is probably more relevant. It seems that the thawing of the ice
caps on
Mars is freeing Co2 into the atmosphere. Could it not be the case here
that the
warming is in fact CAUSING the increase in CO2 rather than BEING the
cause
of warming? As I previously wrote, man has no effect on Mars and yet
it IS
warming. This suggests to me that this is a solar system wide event
and very little
to do with mankinds activities. Just my opinion of course, and it does
seem logical
to me, however I am open to discussion on this.

regards,

Roy

Roy,

did you read the article, or did you just see the headline? It is
nothing to do with CO2 levels but is talking about how tiny
particles of dust trapped in ice in polar regions may store heat and
cause little pockets of liquid water (hence the idea of a special
type of green house effect) and may allow life.

It seems that the basic question is that are the rising C02 levels
the cause of the warming or as a result of the warming? One thing
is for sure, man has had nothing to do with climate change on Mars.
