How Dare You!

How Dare You!

During the 19th century, Greta Thunberg’s ancestor said  burning coal would boil earth and extinct the human race.

23 Oct 1902, Page 1 – The News-Herald at

Steven Hawking picked up on that idea four years ago.

However, this idea was shown to be incorrect by another Swede – Knut Angstrom – 120 years ago. He pointed out some very fundamental errors in Arrhenius’ thinking.

“a layer so thick as to be equivalent to that contained in the earth’s atmosphere will absorb about 16% of the earth’s radiation, and that this absorption will vary very little with any changes in the proportion of carbon dioxide gas in the air”

“The remainder of Angstrom’s paper is devoted to a destructive criticism of the theories put forth by the Swedish chemist, S. Arrhenius, in which the total absorption of CO, is quite inadmissibly inferred from data which include the combined absorption of CO, and the vapor of water. On these incorrect premises Arrhenius has founded an hypothesis as to the cause of the Ice Age, attributing it to variation in the mount of atmospheric CO,. The geologists who have adopted Arrhenius’s views should recall that his hypothesis evidently fails in the light of present knowledge of the absorptive powers of carbon dioxide.”

And 120 years later, the UN climate spokesperson’s father is named after his relative Svante Arrhenius.

  1. Either that 1902 News-Herald reporter misrepresented Arrhenius’ beliefs (most likely!), or else Arrhenius had a change of opinion. That article was in 1902. In his 1908 book, Arrhenius wrote that the effects of CO2 emissions would be extremely beneficial. Here are a couple of clippings from his book:

    “By the influence of the increasing percentage of carbonic acid in the atmosphere [CO2], we may hope to enjoy ages with more equable and better climates, especially as regards the colder regions of the earth, ages when the earth will bring forth much more abundant crops than at present, for the benefit of rapidly propagating mankind.”
    Arrhenius, 1908
