    The Hadley center has just released new sea surface temperature reconstructions going back some 150 years.

    http://www.metoffice.gov.uk/hadobs/hadsst3/

    Ships have been recording temperatures for nearly 200 years, but making sense of all this data is challenging to say the least.

    It includes much more data and improvements to statistical techniques.

    (mental note: I need to learn more about Bayesian statistics.)

    Results and adjustments are posted below:

    It's interesting seeing the uncertainty drop like that so steadily.

    Sea getting warmer, more CO2 going out of solution, ho hum. Utterly predictable, no uncertainty there.

    The uncertainy is related to methods of measurement - canvas buckets and thermometers, versus insulated buckets, versus seawater intake to engine cooling system, versus floating buoys.

    Regarding acidification, the rate of solution of CO2 in the oceans increases as the partial pressure in the atmosphere increases. At present levels the warming of the sea surface is insufficient to offset the partial pressure effect.

    Shifting sampling distribution as well such as readings along broad shipping routes in the age of sail and than later to narrow shipping lanes as we converted to steam and diesel engines.

    All too often the uncertainty and margin of error doesn't make it to the graphs available to the general public. It's almost always included in the original peer-review publications.
