Remain calm grasshopper. Opposing views are part of the game.

Really… I’ve been reading up a lot on CRU versus the FOIA requests that they have received over the last 5-6 years, and they don’t seem to think so.

I’m also looking over the HadCRUT3 dataset. I can see why some people are concerned about the validity of this data. This data is temperature readings, since 1850, in 5 degree by 5 degree grids across most of the planet. But, with in each of those grids, the source of the actual reading (ie: a meteorological station, a individual etc) has/had changed over the years. So, there appears to be no way to validate the actual physical source of the data with in that 5 degree by 5 degree grid. That’s a lot of area in a grid, and temperature can fluctuate inside that grid, depending on the actual pinpoint location and the collection method. CRU says they have no way to reference those actual locations in the grid.

I find that to be possibly a problem.

I have the dataset. My intentions, after studying the dataset and gathering as much info as I can, I am thinking of trying to develop my own program code that would query the data in the same way CRU has queried the data and developed their subsets of the data.

But to do that, I am going to have to beef up on exactly what CRU has been doing with this data, what they have been pulling from this data, and any caveats I need to know.

In the least, I will have a good understanding of CRU’s side of the story and what this data means to them.

Up to this point, a lot of the science, at least reading about it, has been beyond me. But when you start talking hard data, programs and analyzing datasets, well, that’s what I have been doing for 25 years,

Now this gets interesting.
