From the University of Copenhagen - something interesting, but not really surprising. It does make me wonder though about dust and carbon soot related to Earth's own polar ice cap. - Anthony
On Mars's poles there are ice caps of ice and dust with layers that reflect to past climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars's north pole to variations in solar insolation on Mars, thus established the first dated climate history for Mars, where ice and dust accumulation has been driven by variations in insolation.
Reality once again plays unfair with the cult of global warming.
