Phil Jones, the professor behind the “Climategate” affair, has admitted some of his decades-old weather data was not well enough organised.
He said this contributed to his refusal to share raw data with critics – a decision he says he regretted.
But Professor Jones said he had not cheated the data, or unfairly influenced the scientific process.
He said he stood by the view that recent climate warming was most likely predominantly man-made.
But he agreed that two periods in recent times had experienced similar warming. And he agreed that the debate had not been settled over whether the Medieval Warm Period was warmer than the current period.
That last sentence is quite significant, if the medieval warming period was the same or even higher then we have historical temperatures the same as we have now.
As far as his "not well enough organised." comment that I'm going to assume goes back to the quote in my signature. The speculation has been that his work is so screwed up from undocumented dataset changes and code changes that they can no longer produce previous results.
In simple terms they added 1 + X . As they progressed through the years they then went and added X +Y, Y+Z.... Since no one know what X Y or Z is they can't go backwards and explain how they arrived at what they have now.
Time will tell.
