The photographer Bradford Washburn was a contemporary of Ansel Adams. His specialty was the glaciers of Alaska, a series of pictures taken some 70 years ago. David Arnold, an environmental photojournalist from Boston, is an admirer of Washburn's compositions--an art derived from "the convergence of ice and water and rock"--but is also an activist, warning about the impact of global warming. Arnold shared before-and-after shots, replicating the framing in Washburn's landscapes, with ABC's A Closer Look. Arnold shows where mud has replaced Washburn's ice, with as much as 23 miles of melt since 1940. Glaciers have become "icebound canaries, silently warning of an impending more hostile climate," as ABC's Jim Avila (subscription required) put it.
Meanwhile in the southeast, CBS' Kelly Cobiella ticked off the impact of the 18 months of drought: dried swamplands in the Everglades, no spring planting on the farms of Alabama, wildfires in Georgia creating a smoky haze over Atlanta, jeopardized drinking water in Florida. Cobiella made no mention of global warming climate change as a possible exacerbating factor.
