EVEN MORE PROOF THAT THE CRU DATA WAS SKEWED FROM THE START AND THAT THE HOCKEY-STICK IS A BIG FAT LIE

THE CRU LIED WHEN IT SAID CITIES WERE NOT USED IN ITS TEMP DATA.

WUWT - (EXCERPT):

[Karlen] I have noticed that major cities often demonstrate a major urban effect (Buenos Aires, Osaka, New York Central Park, etc). Have data from major cities been used by the laboratories sending data to IPCC? Lennart Bengtsson and other claims that the urban effect is accounted for but from what I read, it seems like the technique used has been a simplistic

[Trenberth] Major inner cities are excluded: their climate change is real but very

local.

[My comment] It is true that the IPCC Chapter 3 FAQ says this:

Additional warming occurs in cities and urban areas (often referred to as the urban heat island effect), but is confined in spatial extent, and its effects are allowed for both by excluding as many of the affected sites as possible from the global temperature data and by increasing the error range (the blue band in the figure).

To check this claim, I took the list of temperature stations used by CRU (which I had to use an FOI to get), and checked them against the GISS list. The GISS list categorizes stations as “Urban” or “Rural”. It also uses satellite photos to categorize the amount of light that shows at night, with big cities being brightest. It puts them into three categories, A, B, and C. C is the brightest.

It turns out that there are over 500 cities in the CRU database that the GISS database categorizes as “Urban C”, the brightest of cities. These include, among many others:

AUCKLAND, NEW ZEALAND

BANGKOK METROPOLIS, THAILAND

BARCELONA, SPAIN

BEIJING, CHINA

BRASILIA, BRAZIL

BRISBANE, AUSTRALIA

BUENOS AIRES, ARGENTINA

CHRISTCHURCH, NEW ZEALAND

DHAKA, BANGLADESH

FLORENCE, ITALY

GLASGOW, UK

GUATEMALA CITY, GUATEMALA

HANNOVER, GERMANY

INCHON, KOREA

KHARTOUM, SUDAN

KYOTO, JAPAN

LISBON, PORTUGAL

LUXOR, EGYPT

MARRAKECH, MOROCCO

MOMBASA, KENYA

MOSKVA, RUSSIAN FEDERA

MOSUL, IRAQ

NAGASAKI, JAPAN

NAGOYA, JAPAN

NICE, FRANCE

OSAKA, JAPAN

PRETORIA, SOUTH AFRICA

RIYADH, SAUDI ARABIA

SAO PAULO, BRAZIL

SEOUL, KOREA

SHANGHAI, CHINA

SINGAPORE, SINGAPORE

STOCKHOLM, SWEDEN

TEGUCIGALPA, HONDURAS

TOKYO, JAPAN

VALENCIA, SPAIN

VOLGOGRAD, USSR

So the CRU is using Tokyo? Beijing? Seoul? Shanghai? Moscow? Their claim is entirely false. In other words, once again the good folk of the CRU are blowing smoke. I can understand why it took me a Freedom of Information request to get the station list.

THE EXTENSIVE USE OF URBAN DATA SKEWED THE RESULTS - AND THEY STILL NEEDED TO "HIDE THE DECLINE" BY TWEAKING THE CODE!

THE WHOLE DAMN AGW THING IS A MASSIVE FUC*ING FRAUD AND A COLOSSAL FUC*ING LIE.
