Climategate Email: UEA’s Phil Jones admits cooling trend (But adjusted data denies it)

From: Phil Jones 

To: John Christy Subject: This and that Date: Tue Jul 5 15:51:55 2005 John, There has been some email traffic in the last few days to a week - quite a bit really, only a small part about MSU. The main part has been one of your House subcommittees wanting Mike Mann and others and IPCC to respond on how they produced their reconstructions and how IPCC produced their report. In case you want to look at this see later in the email ! Also this load of rubbish ! This is from an Australian at BMRC (not Neville Nicholls). It began from the attached article. What an idiot. The scientific community would come down on me in no uncertain terms if I said the world had cooled from 1998. OK it has but it is only 7 years of data and it isn't statistically significant.

Here’s a curious thing. The current satellite data shows a flat or cooling trend from 1998 to mid 2005, but Phil Jones own HadCRUT dataset shows a warming (though not as much as the uber-manipulated NASA GISS. Is this because HadCRUT has been adjusted so that the 1998-2005.5 trend is upwards since Jones made this admission?

This plot, apart from anything else, shows how much uncertainty there is in measuring global temperatures, even within the last decade, when the major datasets can’t agree on the sign, let alone the magnitude of the trend.

    Global temperature is a paramter which is mathematically and thermodynamically impossible.

    Karabar: Correct. The whole thing is constructed on a house of cards.
