Somehow, on this one issue, we throw out the saying that extraordinary claims require extraordinary proof. I've been asking for proof for 10 years now, and haven't seen it.
It's simply not possible for someone to actually want to be informed about AGW and come up with nothing.
By all means, take my challenge to visit the Science Daily climate page and browse. You'll find that the fundamentals of AGW are accepted by everyone, and the questions being investigated now are how fast the warming will occur, what will be the fallout, and how can we slow or stop the warming and/or mitigate the consequences.
I've been looking for raw data for years. It's just not out there. Now, I come to find out that someone has asked for it, and the scientist would rather destroy the data than provide it. Then it is hard to find a skeptic on a board such as this that finds that a bit strange.
It's strange indeed. It just happens not to be true.
If you had followed some of the links that have already been provided, you would have seen that the data were not destroyed. Copies of the data used for analysis were discarded b/c they were redundant, but the raw data still exists, it's still where it always was.
And anyway, the raw data won't help you understand what's going on.
Can anyone out there tell me how the data has been adjusted? Like I stated in my previous post, Tampa tempuratures have risen by 15 degrees in the last 100 years. Just how do they arrive at 0.5 to 0.8 of that to be AGW? I'll get my hands dirty and dig into it.
I hope that some of the folks here who are in the field will help you more specifically with this.
But from what I've seen, there are a few various kinds of adjustments.
Some of them involve putting different sorts of data formats into a common format -- e.g., a very simple hypothetical example of this is if you have measurements in inches and centimeters you have to "adjust" one or the other, or "adjust" them both into some third standard, before doing anything meaningful with those measurements.
Others are necessary to account for differences in physical apparatus and environments -- e.g., if you have a station in an urban area and you're going to include that data in an analysis together with data from a rural area, you have to "back out" the effect of the urban landscape, such as artificial heating from all the concrete.
Still others are necessary for changes to apparatus over time -- e.g., if a station is moved to a location at a higher or lower altitude, then if you do any longitudinal tracking you have to adjust the data or else you'll show a false jump or dip in the readings which is not due to climate but due to the move.
So there's more than one reason why adjustment may be necessary, depending on where the data comes from and what you're doing with it.
