But then came satellite observations, and that lead to the realization that there really has been not warming for the past 17 years or so. So what they did was throw out the satellite readings and just went with land and water based readings. But even that didn't help enough for their purposes, so they adjusted the readings from 1980 to 1999 so that they actually showed a decrease in temperatures during that time - and which of course showed an INCREASE in temperatures from that new lower reading over the past 15 years.
It is interesting reading to see all of manipulations they go through to try to justify their lies...
What sort of devious mind comes up with this crap? Just think if they actually put their nefarious efforts in to doing something good.
