![]() I'm surprised you keep posting the graph of the thirty year satellite record. It's true, it's probably the most reliable one we have, but it's not that scary. Usually when they want to freak people out they go to the 1850 -> Had-CRU, or if you really want to go Alice in Wonderland go with the distorted illusion of NASA/GISS - now that one's good for a scary, hysterical image.
As to this... Quote:
* This only covers the geologically short period of the instrumental temperature period. * It covers a time we were coming out of a cold period called the little ice age, and expected to warm naturally. * 1998 could be seen as a peak, and we currently look to be in a plateau of no statistically significant warming. * PDO has recently flipped negative, and historically that signals a 30 year cooling period. What will your graph look like then, if what has always happened previously happens again? As to the MWP, you could argue about that all week. There's data to come to all sorts of different conclusions. Basically it's inclusive. As such a statement like temperature rise of the last hundred years is unprecedented is nothing more than a debatable possibility. Even when you finish with the argument on how warm, or how rapid the rise was within the MWP, you have to go to previous, warm periods within human history which look like they were even hotter, such as the Holocene Maximum.

But, it's important to consider what was occuring during that period that caused the cooling:
Currently - temperatures are warmer than the period preceeding the cooling so the idea that it is just the "natural warming" following a cool cycle doesn't seem so plausable. Quote:
Well....2005 was the hottest year on record globally. 2009 was the second hottest. But the other factor is what we measure - air temperature is not necessarily the most reliable guage, it is more apt to fluxuate. Measuring the ocean's temperatures are generally more accurate of trends and they show statistically significant warming: Did global warming stop in 1998? There's also a tendency for some people just to concentrate on air temperatures when there are other, more useful, indicators that can perhaps give us a better idea how rapidly the world is warming. Oceans for instance -- due to their immense size and heat storing capability (called 'thermal mass') -- tend to give a much more 'steady' indication of the warming that is happening. Here records show that the Earth has been warming at a steady rate before and since 1998 and there's no signs of it slowing any time soon.

![]() Are you sure understand what the 'little ice age' was, and when it was? It was a cold period between about the 13th century, and the 19th century. As we started to warm, and pull out of it the Industrial Revolution began.
What I said was... Quote:
When you say 2005 was the warmest year, you are, I hope aware you're repeating a contrarian claim made only by James Hansen of NASA GISS. Nobody other than Hansen and his followers believe that. Personally, I've listened to the arguments, and I think Hansen's claims of 2005 as warmest years, and such are based on nonsense. If you don't believe me when I say other collectors of temperature data do not agree with Hansen on this look at your own graph of the satellite record on the previous page. |

Ah, I misread the post. When you didn't specify the period, I automatically thought of this century because there had been talk of a cooling period. My apologies. Quote:
In this chart, the top 20 hottest years since 1961 are listed - they are all from 1983 on and the top 10, with the excpetion of '98 are between 2000-2010. The data is derived from multiple datasets - not Hansen.

The other 2 are NOAA which is Thomas Karl who is this warmist who knows how to get sweet jobs as top bureaucrat in climate. He's famous for having a non-existent PHD. Actually what he has is an honorary PHD, much like Dolly Parton. CRU is Phil Jones, who's the Climategate guy. The Met is the organization in trouble in England right now for making bad predictions, and lying to the public. They're all Warmist slanted organizations. Hansen's not the only one, he's just the worst. The most accurate temp sets right now are probably the satellites. If you check out the UAH graph below... Dec. 2010 UAH Global Temperature Update: +0.18 deg. C Roy Spencer, Ph. D. and the RSS graph here... RSS data: 2010 not the warmest year in satellite record, but a close second | Watts Up With That? you'll see the plateau after 1998 I was talking about. Actually I can even show it to you on hadcrut. ![]() So you see we start to come out of the little ice age about 1850ish. Temps start to rise in a slow, uneven long term trend, which is what you'd expect coming out of a 400 year cold period. After 1998 there's a peak, and a plateau. Yes, measurements along any trend are highest at it's peak. If there's a plateau after the peak they'll all be among the measurements most high. Was that supposed to be a surprise, or something?

I think there's a third side. That would be my side. I think all these rock solid claims of absolute fact from either side are bogus. When you watch the 2 sides argue it starts to look like we really don't know that much about climate yet. These climate arguments become more like literary arguments of your favorite book. However, because we really don't know as much as we think we do, policy proposals become twitchy. For example, check out this one.
