Solar Science Shortchanged in Climate Models

“Indirect solar effects due to the sun’s ultraviolet (UV) radiation or cosmic rays from deep space could also contribute to global warming.”

Solar Science Shortchanged in Climate Models

Here are excerpts from an excellent essay by Ralph B. Alexander, PhD:

Spotless Sun

“The sun gets short shrift in the computer climate models used to buttress the mainstream view of anthropogenic (human-caused) global warming,” writes Alexander. “That’s because the climate change narrative, which links warming almost entirely to our emissions of greenhouse gases, trivializes the contributions to global warming from all other sources. According to its Fifth Assessment Report, the IPCC attributes no more than a few percent of total global warming to the sun’s influence.”

“That may be the narrative but it’s not one universally endorsed by solar scientists,” Alexander continues, pointing to mathematical physicist Nicola Scafetta. Scafetta maintains that “the sun has a significant influence on the climate.”

“I’ve long felt sorry for solar scientists, whose once highly respectable field of research before climate became an issue has been marginalized by the majority of climate scientists,” says Alexander. “And solar scientists who are climate change skeptics have had to endure not only loss of prestige, but also difficulty in obtaining research funding because their work doesn’t support the consensus on global warming. But it appears that the tide may be turning at last.”

“Judging from recent scientific publications, the number of papers affirming a strong sun-climate link is on the rise.”

  1. Scafetta maintains that “the sun has a significant influence on the climate.”

    I think if you ask any 10 year old he could confirm that.

    • Without the Sun this rock would be a frozen rock just like Neptune.

      Solar Global Warming is a fact, during the early part of the Sun’s development – the Young Sun’s energy output was much less then now, and the goldylox zone must further in, perhaps as much to put Venus in the middle of it.
      Now The Sun is more developed and the Goldylox zone is further out, with Mars now on the outer edge of the zone.

  2. Agree with rf121 – I thought by now that everyone in the know knows that the SUN is the Primary Source of Heat for e.g., EARTH..
    Even a Solar Eclipse temporarily lowers Temps in areas in full shadow by upwards of c.8°F.. And The Totality of the Moon’s 265 km wide Umbral shadow lasts at most about 7.5 minutes.. With that said, it is positive to note that OLD SOL can no longer be so ignored.. And that the main Fluctuations of average Earth Temps throughout History connect with the sometimes abruptly changing levels of Solar Irradiation; thanks mainly to Mamma Nature and not Man.

  3. IPCC mandate and mission is to look ONLY at anthropogenic warming. Nnatural causes are to be downplayed and pretty much only man’s CO2 emissions are to be blamed for the..damned near non existant warming we had and have NOT had for some time 18yrs+ at last look see.
    Id like to have been able to stand them all in yesterdays 38+c for 15mins and then deny any effect on temp for old Sol

  4. The influence of the Sun is obvious and I just cannot believe people can be so gullible to believe alarmist stupidity !

    As Earth revolves around the Sun in its elliptical orbit the distance from the Sun changes by 5 million kilometres from 147.09 to 152.1 million km.

    The power of the Sun’s radiation TOA changes from ~1,317 W/m2 in the northern hemisphere summer to ~1,408 W/m2 in the southern hemisphere summer.

    That difference is staggering – imagine what will happen when the northern hemisphere summer occurs at Perihelion with 1408 W/m2 instead of 1317 W/m2 ?

    Or the northern hemisphere winter with 1317 W/m2 instead of 1408 W/m2 ?

    This will happen – significantly hotter summers and colder winters !
