Josh Koch/U.S. Geological Survey

NPR - Hundreds of Arctic rivers and streams are turning bright red-orange, not from chemical pollution, but from naturally occurring iron spilling from long-frozen ground as temperatures warm. The "rusting rivers" phenomenon, which has been documented across the Brooks Range in northern Alaska, offers a vivid example of the effects of climate change in a region that is warming faster than the global average.

A truly independent journalist with his feet firmly grounded in the reality of neighborhoods and everyday people. -- Patrick Mazza, Progressive Populist

A truly original voice in American journalism: humorous and plain spoken and filled with common sense -- Jay Walljasper, Utne Reader

Inimitable -- Mother Jones Magazine

Sam's a cynical cat -- Marion Barry

Sam's one of the few independent voices left. The press today is either extreme or special interest or else just establishment, an extension of the corporate spirit -- Sen. Eugene McCarthy,

A reputation for wit, intelligence and anger. -- Claude Lewis, Chicago Tribune

Whatever the debate, the Review's sharp critiques encourage us to look out our window, notice and act upon what we see, and also to look further -- to the rest of the country and globe -- to see how the organized big world interacts with our more spontaneous small worlds. - Utne Reader
