Is NASA Cooking the temperature books?

I have long distrusted NASA temperature data.   My distrust begins with Goddard Space Studies Administrator James Hansen.  Dr. Hansen is a smart guy, but he has an agenda. He has been publicly trying to convince the world that global warming is a man caused crime against humanity since the 1980’s when he testified before Al Gore’s committee in Senate hearings.

Anyone with an agenda is going to be scientifically prejudiced towards their preferred position, and Dr. Hansen clearly has a specific prejudice.  Everybody working at NASA knows about the bosses prejudices….and I think that can and probably does impact results.

Let’s look at some temperature data.   First stop, the University of East Anglia, UK.

Second stop NASA

And finally the University of Alabama Huntsville (UAH) Satellite data

The first two are surface temperature data, and the third is satellite data.  All three are recognized worldwide as experts.  Which one is not like the others?  NASA!

NASA data used to begin in 1860, and included the very warm years in 1878 and 1879 that are included in the East Anglia data.  And that same old data had the late 1930’s and early 1940’s a bit warmer too.   All current NASA data begins in 1880 and the links to data that went back to 1860 are no longer active.

Both East Anglia and UAH show a pronounced peaking of data in 1998, NASA shows a much lower 1998 and a much higher 2010.   The NASA data is presented in a way that makes it look like global warming is increasing steadily, the other sites  show a peak in 1998 with slight cooling since then.  NASA has insisted that 2010 was the warmest year on record with 2005 second and 1998 third.  East Anglia and UAH like 1998.

So who’s right?   I don’t know, but I have suspicions.  A second satellite site nicknamed RSS (Remote Sensing Systems), generally agrees with East Anglia and UAH.

I wish NASA Administrator Hansen were less emotionally involved.  He is a global warming true believer, and I fear his attitude may cause NASA to look for a specific outcome.
