Good stuff. Probably not covered in NASA DVDs

Quote:Lack of Data For All Phases of Water Guarantees Failed IPCC Projections
Posted on October 22, 2013 by Anthony Watts
Guest essay by Dr. Tim Ball

Lack of temperature data is a problem, but measures of water and precipitation are much worse. Temperature changes, especially cooling, are important to a degree over the long term. Precipitation changes are much more important for short, medium and long periods. Droughts are much more devastating to flora, fauna and the human condition. Irrigation was one of the earliest technologies developed 9000 years ago to offset droughts in the Fertile Crescent, triggered by onset of Holocene warming.

McKitrick et al. and others identified the problems of determining global temperature. Instruments changed over time, but continuous records are limited to the accuracy of early measures ±0.5°C. There are the problems of the recording sites as Anthony Watt’s identified. Only 7.8 percent of the US record is accurate to less than 1°C. What does that say about the rest of the world?

Measuring precipitation accurately is the most challenging of all weather elements. It’s easy if precipitation falls straight down and is only liquid, but it doesn’t and isn’t. Measuring variable snowfall and water content is even more difficult. All precipitation amounts are much more variable than temperature. Some are not considered precipitation. Condensation is overlooked and unmeasured, yet very important.

Tim Ball has an award named after him. It's the "Tim Ball Award for Resume Stretching". But hey, at least this guy didn't lie about his doctorate.

Gee, that's swell dmac. But in the end, you're still wrong.

So there is no issue with the significant digits one should apply to our temperature record?

What am I wrong about, and how did you reach that conclusion?
