Indeed, very well keeping the ball in the game, meaning to not let yourself distract from the current specific topic or random input artifacts. Though i would like to hear Abraham explain temperature surface measurement.
The moderator asked how the surface data is generated.
Gavin Schmidt from NASA did an excellent job, explaining it in his blog
Climatologist Gavin Schmidt Discusses the Surface Temperature Record
…Instead of leaving those areas out from our analysis, you can use numbers from the nearest available stations, as long as they are within 1,200 kilometers. Overall, this gives the GISS product more complete coverage of the polar areas.
NASA: What about the meteorological stations? There have been suggestions that some of the stations are located in the wrong place, are using outdated instrumentation, etc.
Schmidt: Global weather services gather far more data than we need. To get the structure of the monthly or yearly anomalies over the United States, for example, you’d just need a handful of stations, but there are actually some 1,100 of them. You could throw out 50 percent of the station data or more, and you’d get basically the same answers. Individual stations do get old and break down, since they’re exposed to the elements, but this is just one of things that the NOAA has to deal with. One recent innovation is the set up of a climate reference network alongside the current stations so that they can look for potentially serious issues at the large scale — and they haven’t found any yet. http://www.giss.nasa.gov/research/news/20100121b/

Nicely Done.
Sometimes you don’t get as much time to interact, though.
