Ice Caps Melting Due to Climate Change...

...on Mars.

From the Timesonline:
Mars is being hit by rapid climate change and it is happening so fast that the red planet could lose its southern ice cap, writes Jonathan Leake.

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.
Some have suggested that variations in solar activity account for climate change, but that's patently ridiculous. How could a mere ball of gas 93 million miles away have any effect on Earth's climate?
