Already in 1896, a scientist warned about the possible consequences of carbon dioxide emissions, the Nobel committee tweeted.
He also speculated whether variations in the concentration of CO2 in the atmosphere would have influenced climate changes over the longer term.
Arrhenius (1859-1927) does not say so much in this publication that burning fossil fuels will cause global warming. But he was already aware in 1896 that such fuels are a potentially significant source of carbon dioxide.
The Swedish physicist and chemist received the Nobel Prize in Chemistry in 1903 for his work on electrolytic dissociation theory.
