Det villkoret gällde kanske för ett fåtal länders data. Resten hade de kunnat lämna ut på begäran eller göra tillgängligt på nätet. Poängen är attityden. CRU ville inte lämna ut något till smutsiga förnekare.
Detta problem verkar ha varit exklusivt för CRU
"The CRU dataset, which forms the land surface component of the HadCRUT global temperature record, was compiled with the aim of comprehensiveness. The majority of the data in it are derived from the same freely-available raw data sets used by NOAA and NASA. However, it also includes data derived from station data that were obtained directly from countries, institutions and scientists on the understanding that they would not be passed on."
Så titta på NASAs eller NOAAs dataset istället om du tror att detta fortfarande är ett problem.
I usa hade man det mer fritt tillgängliga Global Historical Climatology Network som ägde data själva och delade ut.
"There are two groups in America that we [CRU] compare with and there are also two additional groups, one in Russia and one in Japan, that also produce similar records to ourselves and they all show pretty much the same sort of course of instrumental temperature change since the nineteenth century compared to today.67 [...] we are all working independently so we may be using a lot of common data but the way of going from the raw data to a derived product of gridded temperatures and then the average for the hemisphere and the globe is totally independent between the different groups."

Så titta på och jämför de olika seten.
