Certainly the logic of it, that the temperature trend is unequivocally warming and we are not claimig global warming because of a record or two, still holds, but I thought it might be interesting to revisit the specific data points I raised in it and ask if they are still true.
The temperature data points are from the GISS analysis and can be found here (as you see, I have discovered where they hide their data!).
The statements I made are as follows:
every year since 1992 has been warmer than 1992
the ten hottest years on record occurred in the last 15
Still true, in fact we can now up that to the ten hottest years have occurred in the last 12.
every year since 1976 has been warmer than 1976
the 20 hottest years on record occurred in the last 25
1981 and 1983 with anomalies of .26oC have slipped out of that window so we can now only claim 18 of the hottest years in the last 25.
every year since 1964 has been warmer than 1956
I think this was a typo, because then, and now, every year since 1964 has been warmer than 1964!
every year since 1917 has been warmer than 1917
This is a very safe datapoint.
The five year mean global temperature in 1910 was .8oC lower than the five year mean in 2002
The five year mean in 2006 (the last year for which this can be calculated) is .05oC higher than it was in 2002.
I would venture to predict that global average temperatures will not be below 1974 levels for some number of centuries, notwithstanding some catastrophic volcanism or miraculous technological development.
