Apr 11, 2006 — The debate over global warming and climate change has, for the most part, ended. It's for real. Last week's cover of Time Magazine screamed "Be worried, be very worried". Environmental writer Bill McKibben has been saying that since the late 1980s, when his book The End of Nature sounded one of the earliest alarms about global warming. McKibben's also a practiced student of North Country ecology. He lives part-time in the southern Adirondack town of Johnsburg. McKibben sat down with David Sommerstein to envision what the North Country might be like in a warmer world. He says it's already happening.
