Study: Red planet heating up CNN

Earth’s dusty neighbor Mars is grappling with its own form of climate change as fluctuating solar radiation is kicking up dust and winds that may be melting the planet’s southern polar ice cap, scientists said Wednesday.
Researchers have been watching the changing face of Mars for years, studying slight differences in the brightness and darkness of its surface.
These changes in brightness have been generally attributed to the presence of dust, but until now their effect on wind circulation and climate has not been clear.
