The Blackboard

As summer grows old my red hot peppers ripen I need recipes! This summer the Chicago area has been a bit hot and amazingly humid. I live in the burbs, and sneak veggies into spots planting hot peppers, tomatoes and basil along the side of the house. All are doing just fine. I always grow [...]

I just wanted to give a quick shout out for MoshTemp, frequent climate blog commenter Steve Mosher’s new blog. He’s focusing on temperature reconstructions, providing code in R and discussing R issues in general. Welcome to blogging Steve!

HadCrut and GISTemp have both reported their July anomalies. The HadCrut NH/SH anomaly of 0.529C represents a very slight drop from July’s 0.532; the GISTemp anomaly of 0.55C is a somewhat larger drop from July’s value of 0.58C. Below monthly anomaly values since 1980 are shown for HadCrut, and GISS respectively: There are several interesting [...]

Congratulations to Steve, Ross and Chad for * **McKitrick, Ross R., Stephen McIntyre and Chad Herman (2010) “Panel and Multivariate Methods for Tests of Trend Equivalence in Climate Data Series” in press at Atmospheric Science Letters. (in press). I downloaded today, and I’ve been reading discussions at various blogs. I’m rather glad I waited to [...]

Today, Roger jr asks for a “naive forecast” for a mystery process providing us a data set and ask us how we would create the naive process. The only thing we know about the data is that observations have been made over some periods of time, our goal is to suggest what we would predict [...]

UAH has posted the anomaly for July. At 0.489 C, July is the 2nd hottest July in UAH series 5.3,edged out by July 1998 set the July record at 0.510C. However, it’s still warmer than July 2009′s 0.429C. Those who watched the daily UAH TLT temperatures are not surprised to discover July’s anomaly was warmer [...]

Place your on the August UAH value that will be posted at Roy Spencer’s blog in early September bets here:

Today, I’m going to try something that may reduce the memory problems– but it may also make things worse temporarily. I am going to set “SuperCache” to create a preload cache of every blog post. This could reduce CPU and memory by eventually make the blog deliver static pages when people (and mostly ‘bots and [...]

As some will recall, the bet-challenge for July Sea Ice was to forecast the average JAXA sea ice recorded for the July 18-July 31 inclusive. The results are now in… and the winner is…. DonB who, owing to the small number of betters too all the quatloos! Here are the more detailed results: Winnings in [...]

Frequent commenters have noticed that the blog is throwing a lot of server errors lately. I have not been able to identify the precise cause. Communicating with Dreamhost, it appears that something launches a process that loads a large amount of memory. This causes Dreamhost to start killing processes to keep my from taking down [...]
