The Economist has a good article that sums up the latest picture about the recent release of emails from the Climate Research Unit. This article and a similar article in the New Scientist seem to net out to:
1) The data have not been fabricated by the scientists
2) Some of the scientists have sought to stop climate change sceptics from getting their papers published in peer reviewed journals, by unacceptable methods.
3) Some of the scientists have sought to avoid putting their data in the public domain, which is bad for science.
4) Some of the publicly funded scientists in the UK seem to have tried to avoid their legal responsibilities to answer Freedom of Information requests.
I am glad about item 1 (this is also confirmed by the two other big data sets which have similar results).
Item 2 is a major worry and needs to be investigated, and any academic guilty of it should be disciplined or sacked (depending on the individual circumstances).
Item 3 is a worry, and really the UN, given the importance it places on climate change should recommend that all Governments pass legislation obliging all data to be put in the public domain.
Item 4 is frankly shocking, if it happened (the emails asked for messages to be removed and threatened to delete data - which is wrong, but we do not yet know if anything was deleted). On the face of it it looks like conspiracy to break the law and I would like to see the police as well as academics investigate (FoI is not a criminal issues, but conspiracy to break a law is criminal).
So, what should voters and politicians do? For me the picture is still very straightforward.
A) We have the majority (the overwhelming majority) of the relevant scientists saying that the muck we are putting in the air is warming the planet and that the consequences if we don't do something about it are catastrophic. I don't buy the climate conspiracy, nobody could organise that many scientists to all tell the same story, have you met many scientists, getting them to buy the right brand of coffee is just about impossible!
B) The alternative view is broadly, a) the link between climate change and the much we throw into the atmosphere is not proven and b) we may only get as warm as it was 1000 years ago, and we managed OK then (parts of Greenland had a mild climate from about 800-1300).
If we believe the minority and do nothing, and the majority are right we will have a catastrophe.
If we believe the majority and reduce our use of fossil fuels, provide contraception and education to evey woman who wants it, and cut back on meat eating, and the minority are right, we will have improved our lives and cleaned up our planet for no good reason!
(BTW, meat eating uses masses of water, fossil fuels, produces clouds of methane, and consumes a large amount of food to produce it, and too much of it probably shortens our life - so I am trying to eat less of it)
Publicly funded scientists, politicians, and bankers need to realise the world has changed, they can't fool us for long now, they will be found out. So they all need to start behaving better.
ps when we talk about the data have not been fabricated, I am not talking about things like the hockey stick results. The data are what goes into the hockey stick calculation, not what comes out. The process of calculating the hockey stick chart is a theory, the output is simply a pretty chart expressing the data and the theory - and I have signficant doubts about the hockey stick exercise
