In Reply to: You want to compare a 30 year mean for the month of December? posted by HiFi Guy on January 18, 2007 at 10:16:52:
Its main value is to show that the temperature elevation was consistent across the hemisphere (and indeed the world). If this were "weather as usual" we'd have seen the sort of variability around the mean that you get in normal continental weather patterns. That was not evident. 80% of all land mass in the world recorded elevated temperatures (above their local historic averages) for that month. That's significant, even if this proves to be a one-off. I'd have expected the split to be more 50-50. 80-20? Somebody call Dr. Pareto.When we have a 10 year trend of maps like this, for more than one month a year, then we can say with greater certainty that GW is happening. Until then it's a theory, with strong theoretical underpinnings and a body of evidence that is beginning to grow.
