I commented on large differences
between the deceptively named CRUT3 by the Hadley Centre and the Jones
et al CRUT2. Also see web page. See also, Hadley Centre inserts more warming into New Zealand climate history Supporting web page. Have a look at the ridiculous HadCRUT3 outlier errors in 2003 in New Zealand region SST's , work in progress, more errors to present, I need staff. |

The issue that catches my eye
here is the "about turn" from their 2004 and 2005 conclusions, implicit
in their findings now emphasizing that SOLAR radiation drove the
2003 heat wave but that their greenhouse forcing is driving
decadal warming over Europe. See exact quote below from their Abstract Overall our analysis indicates that heat waves are driven by strong but short-term shortwave forcing, whereas the rapid warming in Europe over the last two decades is primarily related to longwave greenhouse forcing and a strong water vapor feedback. |

My interest in this paper was
sparked by claims on the Jennifer Marohasy Blog. I have been surprised to find that the Philipona et al conclusions are so strongly influenced by their choice of the 1995-2002 period . Classic cherrypicking. |

They show data to end 2003 which
obviously includes the 2003 heat wave. Yet arrive at completely
different conclusions about the 2003 warming compared to
their 2006 paper, Abstract above, where short wave (solar)
radiation is
invoked for the 2003 event. |

GISS
adjustments insert warming into rural stations While working on the Florida 5 degree grid cell page, strange high warming trends were apparent in GISS (NASA's Goddard Institute for Space Studies in New York) graphics at their web site for (at least) two rural stations, Arcadia and Everglades. Includes comments from Dr J Hansen by email This habit of GISS has also been noted in Swedish data. ClimateAudit has several posts on these issues. This one shows how GISS warms more than HadCRUT3 over the USA 48 States. The ClimateAudit search module will find more if you look for giss urban cooling |

This landmark paper
authored by eleven members of the pro-IPCC climate
establishment, is one in a decade long rich tradition
of obfuscating and minimising true Urban Heat Island (UHI)
contamination of datasets by clever misuse of the data aided and
abetted by comradely referrees and sleepy editors. Marvel at the
error ridden colour maps. Peer review ?, what peer review !! |

This paper is notable for its
Fig 7 where the UHI contamination in Chinese and Japanese simply leaps
out of the page. Yet these august authors fail to "get the
message" in their Abstract, or conclusions. Another whitewash of T data which does everything to ignore the UHI effect. As I say, "turning a blind eye." |

This paper is still a vital brick in the IPCC wall of denial of UHI influence in global T trends. This paper has been extensively reviewed and rebutted from the link opposite. This work is ongoing and has been addressed in several posts at ClimateAudit in 2007 which are linked to at the bottom of the " Jones et al 1990 Letter to Nature" page at left. |

The point I am making is that
Jones et al 1986, (see below) published in the same year and in the
same Journal used 10 of Kukla et al's USA cities in their
Northern Hemisphere compilation.
Yet Kukla, Gavin and Karl did not Comment in the Journal on this significant contradiction of their work. |

Review starts at top of page.
Great insights into what Jones et al actually did can be gleaned by
reading scanned pages of the "Comment by Wood 1988 and the Wigley and
Jones reply in which they list 9 errors in Wood's analysis. See my Table juxtaposing
their points with what Wood said. See my point by point comments, make your own mind up. |
