It is a fact that NOAA has “adjusted” the temperatures in the historic record to make it appear that it was cooler 100 years ago. The actual numbers show that it was warmer in the 1930s than it is currently. The actual numbers didn't fit the theory so they changed the numbers. This has been done before and you are correct... it is called fraud.
I recently heard a story that the north pole was expected to be 50 degrees warmer than normal this year, I find it hard to believe, think I will take a plane flight to the north pole and do some temp readings to confirm it, maybe I can get some vacation time and put it all on my credit card
