Mars has warmed 4 times more than Earth over last 20 years

According to the SETI Institute, "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 than 2° for both surface and air temperature, is still significant from a geologic perspective."..."Such a change is very intriguing and has never before been seen on any planet."





Since satellite data indicates the earth has warmed less than 0.4°C over the same time frame, Mars is warming four times faster than Earth. 





Could it be the sun?
