Surface radiative forcings and effects on heat waves and greenhouse warming over the last decades in Europe

Ah, now they discover the cause of the 2003 heat wave.
|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 .

|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)
invoked for the 2003 event.

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."

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.

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.
