The Guardian is so full of BS. How can a "dataset of land-and-sea temperature recordings" be kept confidential when these people are advocating draconian cuts in the use of fossil fuels that would crush the US economy if those cuts were actually implemented? That's crazy. If these "scientists" are going to advocate that kind of radical change in the use of fossil fuels and the resulting massive economic disruption, then they must disclose all their data and all the assumptions and calculations that they use to make their climate forecasts. Full disclosure of all that stuff is very obviously mandatory when people are calling for such massive economic disruption. Anything less than full disclosure amounts to asking political leaders to just take their word for it that the world needs to be thrown into an economic collapse "to save the planet." I suspect they're smoking some kind of controlled substance at the Guardian and also at this "research center." These people are nuts...they're Euronuts. Fortunately Americans have naturally good judgment and we will not follow these European lemmings over the cliff into the sea.
“How can a “dataset of land-and-sea temperature recordings” be kept confidential”
I was wondering the same thing. Imagine Einstein, when he came up with his theory of Relativity, claiming all the data and observations he used to come to his conclusion, were confidential and nobody`s business.
