Take a walk, smell the roses. Any topic is fine, save people bashing.

Why? They're not saying this map proves global warming, and neither am I.

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.
