Mars Heats Up As It Darkens

Just to dash the hopes of those who read the headlines and think this supports the notion that global warming on Earth is natural because it's happening on Mars, you'll have to read the article as well as some additional material to understand that's not the case at all. Reduced albedo, like the darkening of Mars, is one of the compounding mechanisms of Earth's global warming as well (ice reflects more light than water). However, to assume that the cause of such warming is the same would be a mistake as, and this should be painfully obvious, the two planets are very different in terms of their climates (we have a tad more surface water and vegetation than Mars).

Also, I'd like to point out that if one is to accept this research as good science and worthwhile, you'd also have to accept pretty much most of the tools climatologists have used to determine that greenhouse gases are the main cause of warming here on Earth. If you're a skeptic looking for some research that you hope will support your position, you'd be advised to probably not mention this research too much. It actually just goes to prove you wrong.
