BillM: Just one more thing: I've elected, regardless of the accuracy of the data, to illustrate the errors in the AGW hypothesis using the data upon which the AGW proponents base their hypothesis.

Regards.

BillM: You wrote, "I know of NO thermometers with this kind of accuracy and precision earlier than the late 20th century. This is garbage!"

You'll have to have to review the methods they use to determine the errors.

I never noticed your reply. The data you quoted had a measurement accuracy of .0004 in the 1800's and nothing for many other values. I know of NO thermometers with this kind of accuracy and precision earlier than the late 20th century. This is garbage!

BillM: Scroll up to the SOURCES heading, or cut and paste the following:
ftp://eclipse.ncdc.noaa.gov/pub/ersstv3b/pdo/aravg.mon.ocean.90S.90N.asc

The last column should be the data you seek for at least one of the datasets--the error standard deviation for that ERSST.v3b dataset, in degrees C. NCDC does not provide it readily for the “Global Ocean” (SR05) data used in their Global Surface Temperature anomalies data or for the OI.v2 SST data, though I’m sure you could find it if you really needed it.

Skepticism is a good thing. I'm simply plotting the data they present, and the linear trends are created by EXCEL.

I have a question. What are the parameters for accuracy and precision of measurement for the temperature data points? Since you show a computed increase of 0.07 Celsius degrees over 29 years and use two sets of data each with their own variabilities it might imply that precision and accuracy are on the order of =/- 0.0007 Cesius degrees.

Color me sceptical.
