The Blackboard

This Christmas Eve:
frozen ice covers the snow
but our hearts are warm.

Grizelda, Mo, Pyewacket, Jim and I wish you a happy Christmas.

No fancy statistics in this post! I’m just going to show 5 year running means of observations by GISSTemp and the average over all runs from A1B and A2 scenarios:

The 5 year running mean for GISS temp is computed by taking the average over the 60 months prior to the date.
The 5 year running mean [...]

Test for time stamp.

In the wake of Deep Climate’s shark-jumping post accusing Rapp of ghost-writing portions of the Wegman report, blog visitors are discussing libel law. Of course, everyone also remembers Simon giving us an earful about saying bad things about Phil Jones– some of which Simon considers libel, and others have been throwing the word “libel” [...]

I guess one of the African delegations really, really didn’t like the Copenhagen Accord.
However, critics warned the “Copenhagen Accord”, the result of two weeks of negotiations in the Danish capital, was full of holes and lacked a timetable – and environment agencies branded it toothless and a failure. One African delegation likened the deal to [...]

It’s Saturday. It’s cold out. Are you looking for some fun? Take a look at the cache of Deep Climate musings on plagiarism in the Wegman report.
But, go quickly because the original article has been deleted.
The version in cache looks like this:
The most interesting comments are those by Donald Rapp,the man accused [...]

Climate has not prevented Hadley from posting their November tempeture anomaly. The value from HadCrut NH+SH is 0.455F. This is up relative to October’s reading of 0.429 and down from September’s reading of 0.459F. As usual I plotted the values and trends since 2000, and compared to an IPCC nominal projection of “about [...]

Today, Rasmus Benestad explained why Nicola Scafetta should share code to reproduce the results of Scafettas 2006 GRL paper. Rasmus gives some background, explains why he wants the code and relates:
…So I asked him to post his code openly on the Internet so that others could repeat our test with their code. That [...]

Time to bet on the December UAH temperature anomalies for the lower troposphere. You are betting on the value that Roy Spencer will post here early in January.
As many know, I always show the channel 5 AMSU data to help you guess. Mind you, Roy doesn’t use the Channel 5 AMSU when computing [...]

The GISSTemp for November 2009 has been posted. The November 2009 anomaly exceeds the current October 2009 anomaly of 0.64C, and also exceeds the October 2009 anomaly of 0.67C published last month.
Because a blog visitor wanted to know whether the nomimal IPCC Trend of 0.2C/decade still fell outside the ±95% uncertainty intervals, I’ve [...]
