Explain This
There is global warming - on Mars.
How can this be? Other than a couple of roaming NASA probes, there are no SUV's, no smokestacks, no intelligent life, nothing to explain why the Martian polar ice (dry ice) is shrinking. How can this be?
There is a Martian atmosphere, but it's almost entirely carbon dioxide, and has no weather that could disturb the flow of energy from the sun to the Martian surface. And again, without weather, the loss of heat at night should also be constant. Most likely, either the sun is supplying more energy from above or more energy is bubbling up from some sort of geothermal disturbance. In fact, we know now that the sun's output is increasing.
Whatever the reason, this is a natural phenomenon. With its higher temperatures, considerable water, a volatile atmosphere, and a track record of major climate change spanning millions of years, the same could well be true of the Earth.
