You may have seen mention of this in The Limbaugh Letter. I found it hard to accept, even from the pen of El Rushbo, so I went and looked it up. The gist of the article is that from artwork of the 19th century, artist/scientists can tell us how badly we have wrecked our environment. Among other things, the AP report, states:
A group of scientists has studied the colors in more than 500 paintings of sunsets, including many of Turner's 19th-century watercolors and oils, in hopes of gaining insights into the cooling effects caused by major volcanic eruptions.
By better understanding past changes in climate, they hope to improve computer models for future climate change.
Obviously, these graduates of Art History 100, are also cross-credentialed as Environmental Scientists. Funny (ha, ha) that when some (real) scientists question man-made global warming, they are scoffed at as unqualified if they are mere climatologists or earth scientists. Al Gore has no credentials in any scientific filed – he’s not even an art history scholar – yet his word is gospel. Gee, I wonder why.
