Apparenly this year is 0.58C over the 1961-1990 average. Is that a good thing?

Can't be warmest ever, right now I'm having -11C temps, and further up north along the coast my parents have -15C!
/xxx logic.
Well, the average trend has been about 0.3C/62 year since the last cold period (~1600). If you factor in that 1998 was actually the warmest year yet, that means that the deviation since then has actually been downward.Apparenly this year is 0.58C over the 1961-1990 average. Is that a good thing?
That's false, on a few counts.Well, the average trend has been about 0.3C/62 year since the last cold period (~1600). If you factor in that 1998 was actually the warmest year yet, that means that the deviation since then has actually been downward.
Or, to put it another way: we're past the top.
Not really. There isn't much disagreement between the datasets on the overall trend. The primary disagreement is on how sensitive the different datasets are to certain types of variation. The HadCRUT analysis, for instance, is extremely sensitive to the El Nino variation that led to the high 1998 temperature. The overall trend is still basically the same.So, it depends a lot on which dataset you take? And I expect the media to pick the one that shows the largest temperature increase for the previous year.
Did you look at the red line? Not flat at all.Anyway, even your graph shows that the trend has been pretty flat since 1998.
If the rise in temperature were the only piece of evidence in favor of AGW, I would agree with you. But it isn't. The real smoking gun isn't the rise in temperature of the surface, but rather the decrease in temperature of the stratosphere, as this is the fingerprint of greenhouse gas-induced warming.Btw, yes, I know 12 years don't make it climate. But it runs exactly as expected when you look at the graph I posted at the start of this thread. If a few decades create AGW while still being in line with that historic graph, simply because temperatures go up at a faster pace they did the few decades before it, I'll call it being alarmist, or in the case of AGW, mass-hysteria.
Winter has a lot of variability. The trend is still towards warmer winters.It isn't as cold in the winter as it was 30 years ago, but it's getting there (for the last two years), and I expect it to become even colder next year.
So, the last 20 years of strengthening evidence for AGW haven't been enough for you?Let's wait for, say another 10 years and compare notes.
Check the graph again. It takes 5 years for temperatures below 1998 to not affect the moving average. So 2002, would be the first year the average would only include temps from 1998 and up. Does seem flat, but there aren't many samples.Did you look at the red line? Not flat at all.

The graph shows virtually straight line rise in temperature from ~1960 onwards.
Are you dense or what? Frank was referring to temps 1998 and onward. Chalnoth didn't see the "flattening" that Frank mentioned. I pointed out that the end of the graph does appear flat, but it's only a few data points.What are you onto?

Um, that doesn't actually matter, because the 5-year running average continued to go up. This means that, for instance, the average of 2005-2009 was quite a bit warmer than the average from 1996-2000. In fact, if you look at the 5-year running average, 1998 hardly made any impact whatsoever. This is because it was flanked on either side by unusually cold years.Check the graph again.
