apparently it is MUCH worse that I gave credit in the last thread.
Our wanton use of fossil fuels has spread folks, now we are messing up places we never even considered.

an exceprt:
In early April of this year, a young Carl Sagan Center Principal Investigator named Lori Fenton, together with her colleagues at NASA Ames Research Center and the USGS in Flagstaff Arizona, published an article in the journal Nature revealing the phenomenon of the rise in the martian global temperature over the past 20 years. The rise, less that 2° for both surface and air temperature, is still significant from a geologic perspective.
Our Co2 emmisions have spread a few million miles, and are now warming our favorite red planet.
most alarming statement:
Across the past two decades, the model showed the surface temperature of Mars has increased by about 0.65 degrees Celsius (1.17 degrees Fahrenheit).
"That magnitude of change is comparable to what we've estimated for global warming on Earth over the last 100 years," said study participant Paul Geissler of the USGS.
wow!
what does this mean ???
well, obviously I was joking about carbon dioxide levels on mars. However it does show us a planet much farther from the sun (avg 141 million miles from the sun for mars) can have a global warming event. Funny, earth is about 92 million miles, and has a dense atmosphere to trap this heat, where mars does not have much of an atmosphere.
Of course the article listed the hypothisis for this global warming even on mars to be from higher than normal winds uncovering dark portion of martial soil, thus heating up instead of reflecting solar energy back into space...blah, blah, blah....
excellent read if you have the time.
Kinda coincidental dont you think??? Earth's temp rising over the last 20 years more significantly than ever, and mars.....
