Important Questions About the U.S. Temperature Record

Questions continue to be raised regarding the "adjustment" of the United States' climatological temperature data. This video, by Tony Heller, was released yesterday.

The data used in the above video comes from the U.S. Climate Historical Network.

While I readily concede I am not an expert on the pro's and con's of these adjustments, there certainly seems to be validity to Tony's concerns. Here is the data state-of-the-art U.S. Climate Reference Network for which adjustments are neither needed nor applied.
For the period of time the entire new network's data has been available (since 2005), there is no upward trend that I can see. Restated: the rise in U.S. temperatures appears to be, at least in part, an artifact of the adjustments.

Some will reply that the United States' landmass is a small part of the world and they are, of course, correct. However, if the adjustments are misleading in the United States, why should they lead to a better result elsewhere? In fact, scientists have been caught tampering with the temperature record in Australia.

After talking about this with one rather prominent adjustment defender, I have become even more concerned the temperature record is flawed.

Important point: I don't think there is any question world temperatures are warmer than they were 50 years ago. The question is how much heat has the earth actually gained?
