Q&A Part Two: Prof. Phil Jones on Global Warming Rates

Phil Jones is director of the Climatic Research Unit (CRU) at the University of East Anglia (UEA).  The BBC’s environment analyst Roger Harrabin interviewed Professor Jones recently.  Professor Jones’ answers to the first two questions reveal that there is nothing unusual about the rate of warming in the twentieth century.  They also reveal strength of character.

Here’s the question about latest rates of warming compared with other known rates:

Do you agree that according to the global temperature record used by the IPCC, the rates of global warming from 1860-1880, 1910-1940 and 1975-1998 were identical?

Here is Phil Jones’ answer:

The warming rates for all 4 periods are similar and not statistically significantly different from each other.

Here are the trends and significances for each period:

Period Length Trend
(Degrees C per decade)
1860-1880 21 0.163 Yes
1910-1940 31 0.150 Yes
1975-1998 24 0.166 Yes
1975-2009 35 0.161 Yes


Here’s the question about global temperature change since 1995:

Do you agree that from 1995 to the present there has been no statistically-significant global warming?

Here is Phil Jones’ answer:

Yes, but only just. I also calculated the trend for the period 1995 to 2009. This trend (0.12C per decade) is positive, but not significant at the 95% significance level.

Jones is obviously uncomfortable about the implications of the questions (“Yes (I agree), but only just..”).  But he has the integrity to answer truthfully, knowing that the answers cast yet more doubt on the AGW cause, and especially on the IPCC, the CRU and the other organisations that promote AGW.

Because the first proves that there is nothing unusual about the rates of warming we have observed, even though there are now much higher levels of atmospheric CO2 that there were in 1880.  And the second confirms what skeptics have been saying for years – there has been no statistically significant global warming since 1995.  This is in spite of increased atmospheric CO2, and contrary to the exaggerated, repeated claims of accelerated global warming by NASA, the CRU and the IPCC.  So much for the need for urgent action.  We do have time to investigate properly the climatic effects of CO2, methane and whatever other demons are conjured up.

Now, if we could show that the Medieval Warm Period was as warm or warmer than present-day temperatures, and that it was global in extent, we could finally establish that the present global temperature is nothing out of the ordinary.  And that would mean that there is no need for any action at all – at least, not in respect of climate change.  Refreshingly, Phil Jones does not deny the MWP, and is aware of its impact on the debate.  See “References” section below for another blog on Phil Jones answers to the MWP question in the same interview, and how we can test the its extent and temperature during that period.

There are other real environmental issues with which we should deal, and other concerns about depending on diminishing commodities for our energy.  We don’t need global warming baloney to help us recognise those real issues – on the contrary, all the AGW noise has obscured them.

    I think that Jones has no option now but to be truthful or at least not obviously deceptive. There is too much attention being paid to what these folk say now for them to put their foot in it.

  2. JJ says:

    Indeed, you are right. His (acting) successor is yet to learn that. So is Pachauri.
