Svante Arrhenius (1859-1927) was a Swedish scientist who first claimed that the burning of hydro-carbons like coal, oil, gas, peat and wood may cause global warming.
In 1895 he calculated (incorrectly) that a doubling of the atmospheric CO2 concentration would lead to a 4-5o C rise in global temperature.
However, Arrhenius suggested that this increase could be beneficial, making the various climates on Earth “more equable" and stimulating plant growth and food production.
The carbon dioxide scare is proving false - it’s time for some climate sense
Then a showman/politician, Al Gore, gave life to the theory that extra carbon dioxide due to human activities will cause dangerous global warming.
