The model calculated the surface temperature and wind intensity on Mars at the times the maps were made. Both maps show the same area on Mars, but one was made using Viking data collected in the late 1970s, while the other was created with Mars Global Surveyor data collected in recent years.
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.

The research, is detailed in the April 5 issue of the journal Nature
The only remaining question seems to be IS BUSH TO BLAME???
Probably results from those Mars probes disrupting the atural balance of the planet.
