This is a load of crap. Convert the adjusted data back to its raw form using the inverse of the equations that adjusted it in the first place.
They can’t back-calculate. The whole pile of crap that is AGW has turned out to be un-reproducible, forwards or backwards. Nobody can explain what equations were used in the first place.
The media is buying the bs that this is ‘real complicated’....it shouldn’t be that complex at all. They have made it complex to fit their goals; and, the whole un-reproducible charade is the antithesis of the scientific method.
Yet Copenhagen goes on. I want more than on senator to make noise about this.
Those adjustment equations vary from site to site, but all of them adjust upward; from raw data with a +/-1 degree uncertainty factor at that.
The official data all trend toward the +1 side; if one simply uses the opposite sign there is no warming at all and some cooling.
The entire instrument set is inadequate to establish with certainty the current global average temperature and never has.
The focus of persuasion now is extreme climate events as extemporaneous proxies, such as icebergs off New Zealand; calving in Antarctica; excess Arctic ice loss in summer; forest/brush fires in Australia and the southwest of the U.S.; iconic hurricanes like Andrew and Katrina; shrinking sheep in the southern hemisphere; and successful campaigns on recent near-miss catastrophes like Ozone depletion, and deforestation through slash-and-burn, and acid rain.
None of the above scenarios can be verified to be caused by global warming, not a single one.
So how, given this list of successes by the Panic Pimps, do you think this latest failure in the science is going to matter?
It would be like stopping a stampede with a single red flag placed at the edge of the cliff.
