On climate change: from what I understand of the subject, there is only one body of research -- three sets of "cross-pollinated" research of which the CRU was one. Again from what I understand, all three of these sets do not have the raw data available.
I can also say more confidently that none of these people have theories with operant mechanisms that explain the Medieval Warm Period or the cooling cycles towards the end of the Roman Empire and during the Little Ice Age -- nor do they seem to be in a hurry to discover the operant mechanisms behind these changes to world climate.
This does not mean that toxic effluvia like DDT, or the sulfides contributing to acid rain, or whatnot are harmless; but it does mean that it's not clear that "the science is settled" on global warming -- which seems to have stopped and started going the other way in the past 20 years, regardless. I'm not a climate scientist even as an amateur, but recent research seems to point to sunspots as an, or the, operant mechanism.
