‘Two-Thirds Of Climate Warming’ Since 1750 Due To ‘Solar Causes’

November 10, 2017

By Paul Homewood

 

Kenneth Richard has details on the latest paper to find that the sun is driving global warming:

Though advocates of the dangerous anthropogenic global warming (AGW) narrative may not welcome the news, evidence that modern day global warming has largely been driven by natural factors – especially solar activity – continues to pile up.

Much of the debate about the Sun’s role in climate change is centered around reconstructions of solar activity that span the last 400 years, which now include satellite data from the late 1970s to present.

To buttress the claim that solar forcing has effectively played almost no role in surface temperature changes since the mid-20th century, the IPCC has shown preference for modeled reconstructions of solar activity (i.e., the PMOD) that show a stable or decreasing trend since the 1970s.  Why?  Because if the modeled results can depict steady or decreasing solar activity since the last few decades of the 20th century – just as surface temperatures were rising – then attributing the post-1970s warming trend to human activity becomes that much easier.

The trouble is, satellite observations using ACRIM  data (which have been affirmed to be accurate by other satellite data sets and are rooted in observation, not modeled expectations) indicate that solar activity did not decline after the 1970s, but actually rose quite substantially.  It wasn’t until the early 2000s that solar activity began to decline, corresponding with the denouement of the Modern Grand Maximum.

    If the Earth did not have a molten core I wonder if we would be living on an ice ball?

      Yep, no Fe molten core dynamo = no magnetosphere and that = a barren frozen wasteland – and brass monkey’s as is a bit like Mars and all the ladies moved back to Venus – dem silver lined clouds – eh?

      Mars, it woz da sun wot did it, those pesky rays and stringy stuff innit, help!,,,,,,,,,, I can feel an attack of the Fermions coming on!

        Venus has no magnetosphere, but still has by far the thickest atmosphere of the rocky planets.

        Venus, has an ionosphere and thus protects against solar influence ‘wind’ – it is an ‘induced magnetosphere’. Not been an astro-planetary geophysicist, the mechanics of which escape me but not Venusian clouds.

        Venus has a thick pressurized atmosphere held in place by the mass of the planet, Mars has a thin atmosphere and the pressure is not as high as Venus, although both planets have high carbon dioxide atmospheres (Mars 95.9% and Venus 96.5 %) the difference in temperature between the two planets is due to atmospheric pressure, if both planets did not have an atmosphere, their temperature would be equal allowing for distance to the sun, hope that helps.

        BTW Oldbrew, Uranus is a rocky planet, I’m actually becoming convinced that it is the heaviest planet in our solar-system, Just an interesting note.

        One more point about Venus and weak planetary polar fields, they may have become degaussed by the sun’s strong rotating and reversing polar field

      No Dave… that’s what Lord Kelvin thought. He didn’t know about radioactivity…so his science was “settled”.

      dangeroosdave If the Earth didn’t have a molten core and therefor no atmosphere as you suggest, it would not be an “ice ball” no atmosphere!!

    I am confused by this report because the body of it is talking about solar activity which I take to mean electromagnetic activity but the graph is about solar irradience which is totally different and not directly linked to activity.

    Yes, boys and girls, it IS “Our Mister Sun.” Who knew.

      They will all wake up when we get to the fast approaching solar minimum 🙂

      BTW, has anyone thought to ring up Prince Chuckles?

        Nah, they thought CoCo the Clown was better qualified to make sense of it.

        Perhaps they should ring up the Govt minister who is spending (the mot juste I think) 9 days in Bonn along with 44 others .
        Q:How many ministers , deputy ministers , civil servants and general dogsbodies does it take to give away billions of UK taxpayers money to unaccounted destinations ?
        A: 45 this time , and another 45(?) at the next climate summit next month.
        Thank goodness we are a rich nation , with no need of this money for schools, NHS and transport infrastructure.

        You have reminded me of the ever relevant ‘Yes Minister’ …

        James Hacker: “Who else is in this department?”

        Sir Humphrey Appleby: “Well briefly, Sir, I am the Permanent Under Secretary of State, known as the Permanent Secretary. Woolley here is your Principal Private Secretary, I too have a Principal Private Secretary and he is the Principal Private Secretary to the Permanent Secretary.
        Directly responsible to me are 10 Deputy Secretaries, 87 Under Secretaries and 219 Assistant Secretaries.
        Directly responsible to the Principal Private Secretary are plain Private Secretaries, and the Prime Minister will be appointing 2 Parliamentary Under Secretaries and you will be appointing your own Parliamentary Private Secretary.”

        James Hacker: “Do they all type?”

        Sir Humphrey Appleby: “No. Mrs. McKylie types. She’s the secretary.”

    The next few years will be the proof of this. The sun has been spotless for over a week now and on iceagenow there are lots of cold records being set due to the polar vortex. A bit odd in the warmest time the planet has evah known. And surely a vortex from the arctic will be bringing all that warmth they tell us is up there down across the US and Canada? Still, with all the snow in the Alps and Pyrennees allowing an early start to the season you can go skiing to take your mind off all this global warming stuff on the snow that is not supposed to exist any more.
