Recently, a number of emails have been hacked from the University of East Anglia's Climate Research Unit (CRU). Many articles have come out by atmospheric scientists and journalists indicating that the hacked emails point to one thing: the scientists at CRU were falsifying ("cooking") their data [look here, here and here]. They appeared to be doing this to force the data to match a foregone objective: that the earth is warming as a result of carbon dioxide, methane and other so-called greenhouse gasses.
