From what I understand, they're supposed to tweak their temperature readings that they take in cities DOWN to match the temperature readings taken in more remote locations since the remote readings are more accurate, and since cities are hotter than the surrounding countryside. What they instead do, to push this bullshit, is adjust the remote temperatures UP so that the average ends up higher and they can exclaim "LOOK ITS GETTING WARMER!" when it really isn't.
