Email that Jim Hansen sent out last night

A draft paper "Current GISS Global Surface Temperature Analysis" is available at http://data.giss.nasa.gov/gistemp/paper/gistemp2010_draft0319.pdf  
Criticisms welcome.  I intend to revise it for submission to a journal within a month or so.
 
Sorry, it is too long for popular use.  Here are some of the main conclusions:
 
(1) Contrary to popular belief, global warming has not stopped nor has the rate of warming even slowed down in the past decade (Figure 21).
 ...Of course winter weather will always be highly variable and those places cold enough to have snow can expect greater amounts from an atmosphere containing more water vapor.  The AO indices for the past three months are remarkable (Figure 15a), yet the cold temperature anomalies are relatively small compared to say the late 1970s (Figures 15b, 16, 17).
 ...
Somehow we have to do a better job of communicating.  The tricks being used by people supporting denial and business-as-usual are recognizably dirty, yet effective.  We are continually burdened by sweeping FOIA (Freedom of Information Act) requests, which reduce our ability to do science and write it up (perhaps this is their main objective), a waste of tax-payer money.  Our analyses are freely available on the GISS web site as is the computer program used to carry out the analysis and the data sets that go into the program.
 ...
It seems that a primary objective of the FOIA requestors and the "harvesters" is discussions that they can snip and quote out of context.  On the long run, these distortions of the truth will not work and the public will realize that they have been bamboozled.  Unfortunately, the delay in public understanding of the situation, in combination with the way the climate system works (inertia, tipping points) could be very detrimental for our children and grandchildren.  The public will need to put more pressure on policymakers, enough to overcome the pressure from special financial interests, if the actions needed to stabilize climate are to be achieved.

Phil Jones, when on the witness stands seems to disagree. Maybe next year after the elections we will see Hansen in the same place.

Would you like some cheese with your whine, Jim?

He really is in denial, isn't he?
