Mars: climate change faster than thought

And Mars seems like a more boring, static place than the Earth with its constantly varying cloud cover and turbulence in the atmosphere. The idea that the Earth should be naturally keeping its global mean temperature constant within tenths of a degree doesn't sound sensible given the facts we know, especially the big-picture physical facts that also involve those from other celestial bodies.

Some of the global warming on other planets (and our blue, not green planet) has been attributed to the Sun and/or nearby cosmic rays. The shared positive sign in most cases is suggestive but I remain an agnostic here. The internal, mostly random planetary variability is still a plausible explanation for all the changes.
