State of the Climate 2017

March 27, 2018

By Paul Homewood




The GWPF has published its State of the Climate 2017 Report, written by Ole Humlum, former Professor of Physical Geography at the University Centre in Svalbard, Norway, and Emeritus Professor of Physical Geography, University of Oslo, Norway.


Here are the main points:






Lower troposphere temperatures show the persistence of the pause:




Of particular interest is his comment about sea levels. Here is the section explaining tidal gauge trends:






Note how the 10-year sea level changes in the bottom panel have a wavy pattern, but the recent rate of rise is no different to many other periods since 1900.

[The graph is not very clear, but the nine stations used are Auckland, Trieste, Newlyn, Cascais, Honolulu, Balboa, San Diego, Key West and New York}

While the relative sea level rise (RSL) is the only thing that matters at the individual sites concerned, it should not necessarily be expected to match the absolute global rise, as measured by satellites. But what is key is how the rate of rise has changed since 1900. In other words, is it accelerating?

We only have satellite data going back to 1992, so that is unable to answer the question. But Holgate’s tidal gauge data strongly suggests that there has been no acceleration.

    Another excellent report from the Global Warming Policy Foundation, which has produced a string of excellent summary reports. The GWPF is the only place to go to for authoritative summaries of the evidence.

    The 10-point executive summary tells me that the climate will get cooler in the future.

      “‘Stadium Waves’ Could Explain Lull In Global Warming”

        Gives comfort to those who believe ‘something’ is masking AGW and its still going on. Its more information to support the certainty that we can’t be certain about any of this stuff.
        Personally I regard it a bit like ‘string theory’ in physics, its too damn clever for its own good and there is no way you can explain it on the back of a postage stamp.
        We need simple refuting of CO2 forcing. Something that is so simple and nice and good and warm and cozy. We are never going to stop this madness with ‘science’, especially science that no more than 0.0001% can understand.

    Point 1 is bad news for the Warmists and their evah warming planet. Having 2018 as lower still will be devastating but the fiddlers will be on the case – or as PH has shown for New York, already at work.

    Well done to the GWPF,another excellent report.But I sincerely hope that they do not have lamb stew in their dining room,as according to Vine on the Beeb today,some people described as scientists have decided that the dear little creatures(the lambs I mean) produce too much methane;a greenhouse gas,so called.Some people really need a different job.

    Reblogged this on Tallbloke's Talkshop and commented:
    From the GWPF’s own preamble to the Humlum report, quoting the professor:
    “It is clear that temperatures in the troposphere are continuing to diverge from surface temperatures. In other words, they are warming more slowly than global warming theory says they should. The contrast with theory is even more marked in the stratosphere, where temperatures have barely changed for 23 years. We still have much to learn about the climate.”
