Well, this seems a bogus argument. Why the NASA and the NOAA would be tampering the data while they are publishing the changes in their website and publishing their methods in peer-reviewed papers? Everybody is seeing that they are making changes. Their website even allows the user to compare each versions with another. NASA's scientists are smarts but not that much to hide their evil tricks? Actually, they gave good arguments for these changes and everything is transparent and free to access. The changes by each versions are not consistent with the purpose of increasing the warming trend since even older values get warmer (which is actually reducing the warming trend). In fact, it seems that the website you are relying on is actually the source of deceptive arguments and manipulation. Their dataset is comparing two different types of data to make you believe that the changes are very high (going up to 0.4°C while they are less than 0.15°C with a correct dataset comparison). And their perpetual recall to the figure of Hubert Lamb made in 1965 as a proof of manipulation is not only deceptive, this is as well really stupid.
At the end, your argumentation from all your messages in this thread looks like this:
You are saying that the dataset from the NASA, an American independent agency, is manipulated to create a warming trend.
You are saying that the dataset from the NOAA, an American government agency, is manipulated to create a warming trend.
You are saying that the dataset from the MetOffice, a British government agency, is manipulated to create a warming trend.
You are saying that the dataset from the JMA, a Japanese government agency, is manipulated to create a warming trend.
You are saying that the dataset from the Berkeley Earth, an American independent non-profit organization, is manipulated to create a warming trend.
You are saying that the dataset from the University of Alabama in Huntsville (UAH), an American state-supported research university, is manipulated to create a warming trend.
You are saying that the dataset from the Remote Sensing Systems (RSS), an American private research company, is manipulated to create a warming trend.
You are saying that the dataset from the ECMWF, an independent intergovernmental organisation supported by 34 states, is manipulated to create a warming trend.
Etc.
