According to an article in the 23 Aug. issue of New Scientist magazine (unfortunately not available online to non-subscribers) scientists have been “absolutely shocked” to find that glaciers in the south pole have been “eroding at a rate of 3 meters per year or more.” According to one scientist “all the visible ice, all the carbon dioxide that we see in the ‘permanent’ ice cap could be eroded in less than a century.”
The scientists agree that the only plausible explanation of what they are seeing is “climate change” but none of them think that humans are to blame. Why not? The scientists are talking about Mars. The article doesn’t make the connection but it seems to me that global warming on Mars raises the plausibility of claims by global warming skeptics that solar activity could be responsible for much climate change on Earth. Here is a picture from Friis-Christensen and Lassen’s 1991 paper on this issue in Science (link to JSTOR, click on the picture to expand).
