The multiproxy world has been a little quiet since AR4. Eerily quiet. But the Team has plans to liven things up in the June 2008-9 year with plans for a: Broad announcement of [PR] Challenge to paleo, modeling and statistics communities (e.g., EOS, BAMS, PAGES, CLIVAR, PaleoList, AmStat, EGGS, Nature Reports). They didn’t mention Climate […]
Lewis Richardson’s famous 1920 climate science paper ‘The supply of energy from and to Atmospheric Eddies’ was neatly summarized by the poem: Big whorls have little whorls That feed on their velocity, And little whorls have lesser whorls And so on to viscosity. Isn’t that a brilliant description of turbulence? So climate scientists have, from […]
Yesterday, in a passing comment, I mentioned an article by Osborn et al, Annually resolved patterns of summer temperature over the Northern Hemisphere since AD 1400 from a tree-ring-density network, as an example of abuse of terms like “rigorous” or “conservative” to arm-wave through proper methodological description. Here’s an example of their use of “rigorous”: […]
During the last few days, there has been a flurry of activity following an announcement by Xian-Jin Li of a supposed proof of the Riemann Hypothesis, perhaps the most famous unsolved mathematics problem (now that Fermat’s Last Theorem has been solved.) Atle Selberg, an eminent mathematician, recently said: If anything at all in our universe […]
I’ll post up some utilities for reading sea ice here (soon). For now, I want to document some relevant aspects of the data sets. NSIDC Daily Data Sets Arctic sea ice information from NSICD is available in two directories: ftp://sidads.colorado.edu/pub/DATASETS/seaice/polar-stereo/nasateam/near-real-time/north – has daily 2008 data; ftp://sidads.colorado.edu/pub/DATASETS/seaice/polar-stereo/nasateam/final-gsfc/north/daily – has daily data for years prior to 2008 […]
I’ve got a question for readers: can someone explain to me how the NSIDC sea ice projections were actually made? I can’t get from A to B. Relevant information is in their monthly reports for April 2008 and May 2008. Remember how much we’ve heard about new ice and why this was expected to lead […]
You have to get up pretty early to be first out of the blocks on monthly temperatures. This month, Climate Audit is first out of the blocks with June 2008 monthly temperatures. June 2008 MSU results (anomaly deg C), coming soon at http://vortex.nsstc.uah.edu/data/msu/t2lt/tltglhmam_5.2, are GLB: -0.114 (June 1988: 0.100), NH: 0.004 (June 1988: 0.140), SH: […]
For anyone who’s betting that 2008 meltback will exceed 2007 meltback, I think that you’ll be able to pretty much know where you stand by the end of this week and your chances are not looking good right now based on this week’s exit polls. Another Climate Audit first.
The fraud trial of Conrad Black has been a very large story in Toronto. Black, a business tycoon, was recently sentenced to 78 months in Chicago; last week his appeal was rejected – news story here; blog account here; judgement here. Interestingly, the judge has his own blog. Black and his co-defendants were executives of […]
