I've looked at some historical temperature data for Pittsburgh. The data goes back to 1870. By far, the warmest era was 1877-1902. The coldest era was 1940-80. The other two were in the middle, including the one we're currently in. Will the next one be cold or hot?

My guess is if this data extended back 1000 years, we would see an oscillation like this.

If have apparently read it and thus are able to see that 2010 and 2005 were warmer than 1998. To ignore the linear line is dishonest to say the least. Did you watch the press conference? Do you understand your own data you just posted above? If I'm pulled over by the police for driving 65 miles/hour in a 60 zone, but his radar gun has an accuracy of +/- 10 miles/hour, then he cannot give me a ticket because he doesn't' know if I was going 55, 65, or 75.
You claim:

"that the world has not warmed since 1998"

"The temperature has not increased at all since 1998"

Then you present links that contradict your own claims.

And you call me as dumb as a flat earther and tell me to grow up?

You seem to think that a slowing in the rate of increase in global surface temperatures using a high baseline in an el Nino year (1998) means that the "temperature has not increased at all since 1998" or that "the world has not warmed since 1998"?

Fact: The last decade was the hottest on record globally. Each year from 2000 to 2010, except 2008, was in the 10 warmest recorded globally. (GISTEMP, HadCRU).

Do you also not realize that surface temperatures are only one measure of warming?

Do you also think the arctic ice is growing because you read it in the Daily Mail?

Pittsburgh doesn't equal the world. And AGW doesn't imply that warming will go up linearly, there will still be warm and cold eras... AGW is saying the overall trend is that the globe will be warmer.

"that the world has not warmed since 1998" Yes, because it is true. You even posted data supporting my position.

"The temperature has not increased at all since 1998" Again, true. See you own data.

You seem to think that a slowing in the rate of increase in global surface temperatures using a high baseline in an el Nino year (1998) means that the "temperature has not increased at all since 1998" or that "the world has not warmed since 1998"? Well if you graph it, it kinda shows just that. Will the earth continue to flatline into the future? Personally, I doubt it.

Fact: The last decade was the hottest on record globally. Each year from 2000 to 2010, except 2008, was in the 10 warmest recorded globally. (GISTEMP, HadCRU). That is true. Never said it wasn't.

Do you also not realize that surface temperatures are only one measure of warming? Again, this is true.

Do you also think the arctic ice is growing because you read it in the Daily Mail? That depends on how far back you run your graph. If you do it back to 2007, then yes it is growing, but if you run it back to 1998, then no, it is shrinking. The overall trend is still shrinking, just as the overall trend for temperature is warming even though it has stalled out for what is likely a temporary hiatus.

If we take the margin of error away, and consider the strong El Nino year of 1998, then I think that talking about the flat-line or hiatus is much less debatable when we start from 2001 to the present instead.
