"The scientific opinion is that we have a ceiling of 440 parts per
million [ppm] of atmospheric carbon before there is a tipping point, a
step change in the rate of global warming," said Professor Smith.

RC did a good-humoured take-down of some of the "tipping points"
rhetoric some time ago. But it keeps on coming back like a bad
penny...it really makes me wonder if there is something in the human
psyche that requires the existence of an impending catastrophe.
(Whatever happened to good old bird flu?)
My prediction, for what it's worth, is that we will be told we have "10
years to act" indefinitely, certainly well beyond a decade from now,
irrespective of any actions that are taken.
