Pollack in NYTimes: Canary in the Ice
April 3, 2012
Re “Weather Runs Hot and Cold, So Scientists Look to the Ice” (front page, March 29):
Nature’s best thermometer and most unambiguous indicator of climate change is ice. Ice asks no questions, presents no arguments, reads no newspapers, listens to no debates. It is not burdened by ideology and carries no political baggage as it crosses the threshold from solid to liquid. It just melts.
The continuing loss of summer sea ice in the Arctic Ocean is indeed affecting the weather beyond the Arctic. The canary of climate change is crying out, and ever louder.

The writer, professor emeritus of geophysics at the University of Michigan, is the author of “A World Without Ice.”
The metaphor of the canary in the coal mine is apt for threat of global climate change.
The question is, how many dead canaries do we need to find before someone gets the message?
