Scientists from Nasa say that Mars has warmed by about 0.5C since the 1970s. This is similar to the warming experienced on Earth over approximately the same period.
Since there is no known life on Mars it suggests rapid changes in planetary climates could be natural phenomena.
The mechanism at work on Mars appears, however, to be different from that on Earth. One of the researchers, Lori Fenton, believes variations in radiation and temperature across the surface of the Red Planet are generating strong winds.
In a paper published in the journal Nature, she suggests that such winds can stir up giant dust storms, trapping heat and raising the planet’s temperature.
Yeah, dust. Right. Or it could be that the sun is having a 1000 year sunspot maximum and there's more sunlight shining on Mars, which is making for more wind and more dust as well as heating things up.
Naw, it must be my truck doing it.
