Ego - my take is that these revisions of the data are basically ludicrous and they show how poorly the science is being conducted within this field. It's actually exactly what I am talking about when they keep waving their hands and hoping no one notices. If you have though a political affiliation you may buy it. If you are looking at the facts there is no way you buy it.
I think that this is just another example of the fraudulent behaviour by so called "scientists" to keep the gravy train running. I also think that this is the type of behaviour that has resulted in the backlash against this cause.

You can go ahead and believe this fraudulent behavior if you want too. The good thing is that in another 10-20 years they will do it again and again but the impact will remain the same - i.e. non-existent.
I'll add that there is the possibility that there is some warming occurring but it is going to take decades to see if this is really the case. This warming (if it is occurring) does not mean that AGW is occurring. The next point is that the significance of any warming is miles off any alarmist hypothesis.
So there are a bunch of factors against the alarmists:-
1. No temperature increase in the last 15-20 years. You can debate this if you want too but you are really clutching at straws.
2. No impacts ala the alarmist crapola as in:-

3. The science is pretty clear cut on CO2 having minimal impact on the climate.
4. The feedback mechanisms of the Earth's climate are not well understood. This is the last bastion of the alarmist but don't let them scam you. There is no proof whatsoever that the feedback mechanisms are positive.
The question remains do we now state that this is definitively a false hypothesis or do we hang on and reassess this over the next couple of decades ?
We definitely should all relax and be extremely comfortable that the alarmists have massively overstated their case and there is no need for any action on our behalf. Worst case let's assess this over the next couple of decades but at the same time let's go and use those funds that are being directed towards a false claim towards something meaningful.
