Climate Change roundup

1. Science & Public Policy highlight this paper by Joseph D'Aleo about Jim Hansen and his grasp of science. Here are some extracts that I found revealing:
'NASA makes frequent changes to the data as noted. John Goetz in a guest post on Watts Up With That noted how NASA changed 20% of the station data 16 times in the 2 1/2 years ending in 2007. Recall also in 2007, Steve McIntyre found a ‘millennium bug’ in the NASA software that caused excess warmth post 2000. NASA quickly adjusted the data down 0.12 to 0.15C. This also pushed 1934 back into the lead as the warmest year. That lasted all of one year (NASA kept the old data the same because the world was watching) before NASA returned all that warmth and then some.'

'Hansen is a man on a mission to save the planet and this includes civil disobedience. As Michael Goldfarb described it “Recently, but presumably still in his capacity as a private citizen and defender of the Earth, Hansen wrote an op-ed for the Guardian in which he described coal-fired power plants as “factories of death.” This on the heels of testifying in a British court on behalf of six Greenpeace activists on trial for causing $60,000 in criminal damage to a coal-fired power station in England.” Could this civil disobedience carry over to the data?
The cooling with the recent two year La Nina has put pressure on NOAA and NASA to accelerate adjustments - NOAA removed urban heat island adjustments for the USHCN in 2007 and announced a new warmer version of GHCN (V3) coming soon. NASA’s adjustment upward of this decade last year (shown in table above as much as 0.19C for a year-2005) put them in a position to make the claim in the release. Should you believe the NASA and NOAA claims? No, no more than those from the Hadley Center/IPCC.'
