"It has been said nothing is invented that wasn’t first written by nature. After viewing the Double Exposure exhibit, there is no denying nature has written an inscription on the receding glaciers of Alaska and the Swiss Alps that says climate change is at hand. And for those who won’t believe it, or don’t care to read the signs, it is not for lack of evidence in black-and-white photos by Brad Washburn and David Arnold that offer stark, beautiful, and indisputable proof global warming is not an invention."
