This story by Seth Borenstein, AP Science Writer, is sure to create a lot of heat from those who dispute global warming. Without revealing what the numbers represented, his news organization gave temperature data to four independent statisticians and asked them to look for trends. They found no evidence of any decline – only a long-term increase over the last 130 years, thus taking away fuel for the fire that the world is now cooling.
I like the idea of this being a blind analysis, although I wonder if these four statisticians might’ve seen through this. Also, what is a good sample size for statisticians? Four seems meager. Do you pick statisticians at random, or what?
Anyways, I am more concerned about my Minnesota Gophers going to a new outdoor stadium in what will turn out to be one of the coldest Octobers ever in this region. They play Saturday night, which is Halloween – scary enough on a college campus –but it might be wickedly cold as well. Fortunately I have a good collection of Gopher shirts, sweats and jackets to put on layer-by-layer. I noticed something funny about being outdoors after so many years of under the Metrodome: People clapping with mittens on just doesn’t work as well for cheering purposes.
