I try to stay on topic, but sometimes I stray.
Nobel Prize-winning economist Paul Krugman in today’s Times:
The fact is that the planet is changing faster than even pessimists expected: ice caps are shrinking, arid zones spreading, at a terrifying rate. And according to a number of recent studies, catastrophe — a rise in temperature so large as to be almost unthinkable — can no longer be considered a mere possibility. It is, instead, the most likely outcome if we continue along our present course.
In other words, we’re facing a clear and present danger to our way of life, perhaps even to civilization itself. How can anyone justify failing to act?
