To complete my response to dogtowner's accusations that scientists have been faking the data, here is the complete list of the four claims he made and my responses. Farther below in this post I have a summary of his accusations and those of Asur. Overall, I still don't see any evidence of scientists manipulating data in serious ways except possibly for the accusations of the conservative Russian economists - if they can be trusted and if there are no other explanations for why the scientists might have chosen to remove the data.

I don't believe this one at all. This is a link to a scientist or engineer who is ranting about his frustrations in being the first person to put a database in order and finding missing and partially corrupted files. Please. I have tried to do things sort of like this before, and I can tell you that there are problems like this in many databases without assuming foul play. I see no reason to assume dishonesty. You will note that the author of the actual
source readme never says that he suspects foul play, but spends lots of time blaming bad software.

This is an accusation of cherry-picking data, not faking data. I have not been able to find much detailed information about it, so I cannot conclude at this point whether it is valid or not. There are many reasons why scientists might choose to remove 40% of the temperature stations from their analyses. Maybe they determined some of the stations were unreliable or were not relevant to particular things they were studying. Also note that it is not impartial scientists who are claiming foul play. Rather it is Russian economists who contain prominent links on their
homepage to the Cato Institute ... clearly an economic group with conservative leanings. So they aren't exactly an impartial group.

This accusation is obviously false. The blog goes through and finds that the the temperature trend only exists because of a correction the climate scientists made to the raw data. Instead of asking why the correction was made, they screamed "foul play, fabrication of data!" Turns out
the temperature stations have not been in the same locations for the last 100+ years, so corrections have to be made to account for these differences. In particular, one of them was moved to a much higher elevation where it is significantly colder so that the temperatures have to be corrected upwards for comparison.

No examples of faked data here, just vague accusations.
Overall, between dogtowner and Asur, I can remember five serious accusations of scientists fabricating or distorting data. a) CRU scientists playing a trick to "hide the decline" in temperatures. b) Realclimate altering data. c) Data is altered because files in a database are messed up and don't agree with each other. d) Russian data was used selectively to create a false warming signal. e) New Zealand scientists manipulated data to create a fake warming signal.
a and e are obviously false accusations that only get any attention because the average person is ignorant of the science and statements have been taken out of context (in a's case). b is an accusation that Asur made but never even tried to back up despite my repeated requests, so I see no reason to believe it. c is almost certainly false. Files in databases have problems all the time without foul play being involved. d is the only one I am not sure about, but it is being made by what appears to be a biased source of people who have no scientific expertise, so I have no strong reason to trust it.
Overall, there is dishonesty among scientists just like there is dishonesty among people of every profession. For some reason many false claims of dishonesty are spreading about scientists recently, and you guys are choosing to believe them all without question, even when they are being made by groups that are being paid to undermine the science because it supports the Democratic agenda (many bloggers at conservative sites). I am sure that you will all ignore my studies here, just as you have ignored almost all the science I have explained to you because it undermines your certainty that the scientists are liars and global warming is a hoax. But if nothing else, I feel that I have closed the loop and have a better understanding of these issues myself.
Cheers!
