Recent pictures from Mars reveal patterns on the surface indicative of melting ice and the subsequent "flow" of water. Given that pictures of the same area taken just a few years ago did not show melting ice/water, one has to wonder......if Earth and Mars are BOTH heating up....what is the common denominator?
I am not saying that humans are not partly to blame, but clearly the sun is a factor too. And NOBODY wants to discuss it, because it is something we have absolutely no control over. At least with "its all due to us" arguments there is some comfort (however naive) knowing that we may be able to control it to some extent.
But the sun?
......scary
