The IPCC Climate Change 2007 report predicts world temperatures will possibly rise 1.8C to 4C (3.25 to 7.2F) from 1990 levels to the year 2100 and that sea levels might rise 28 to 43 cm (11 to 17 inches).
Just six years ago, however, the picture looked much bleaker.
The 2001 IPCC report predicted that from 1990 to 2100 temperatures would rise 1.4C to 5.8C causing sea levels to rise by .09 to .88 metres (3.5 to 34.6 inches or 9 to 88 cm).
In other words, in just six years, predictions about temperature increases have plummeted by one-third and predictions about sea-level increases at the high end have been cut in half!
At that rate, by my calculations, we'll just have to wait for two more reports and the IPCC will be predicting no measurable increases at all!
Incidentally, many climate scientists have been saying just that -- wait until 2025, when it's expected the sun's output may wane, leading to global cooling.
Another measurement has had to be slashed by one-third as well.
In 2001, the UN body said the global net effect of human activities since 1750 has been one of warming with radiative forcing of 2.43 watts per square metre.
Oops. Now they're saying it's 1.6 watts per square metre.
Shouldn't someone at least be blushing? Shouldn't they apologize for getting all of this so wrong?
