  1. Go a step further than Spencer’s book.

    Discover the cause of the warming, the end of it, why temperatures are headed down and what to expect.

    The two primary drivers of average global temperatures explain the reported up and down measurements since before 1900 with R2>0.9 and provide credible estimates back to the low temperatures of the Little Ice Age (1610).

    CO2 change is NOT one of the drivers.

    The drivers are given at


    which includes eye opening graphs of the past, what to expect, and a plethora of links and sub-links to the credible data sources that were used.

  2. : “…when there is a mixture of radiative and non-radiative forcings of temperature occurring, natural cloud fluctuations in the climate system will cause a bias in the diagnosed feedback in the direction of positive feedback, thus giving the illusion of an overly
    sensitive climate system.” His argument is based on a new way of examining relatively new data, and
    creates an “aha” moment. ”

    While not denying a PDO role in clouds, I think anthropogenic aerosols (reductions in) are likely more important in cloud changes, especially low level clouds.

    And I think the main error climate science made was to assume changes in minimum temperature result from changes in night-time temperatures. I wrote about this a couple of years back using the work of Jonathan Lowe. In summary, minimum temperatures give a spurious warming signal.
