At first, I thought this had to be a joke. Then I thought it must be some sort of misinterpretation. Sadly, no.
According to her mother Malena Ernman (48), 16-year-old Swedish climate activist Greta Thunberg can see CO2 with the naked eye. She writes that in the book ‘Scenes from the heart. Our life for the climate’, which she wrote with her family.
Greta was diagnosed as a child with obsessive-compulsive disorder and Asperger’s syndrome, just like her younger sister Beata. The activist also has a photographic memory. She knows all the capitals by heart and can list all the chemical elements of the periodic table within one minute. In addition, she has another gift according to her mother.
“Greta is able to see what other people cannot see,” writes Malena Ernman in the book.
“She can see carbon dioxide with the naked eye. She sees how it flows out of chimneys and changes the atmosphere in a landfill.”
Of course, with a ~ 410 parts per million concentration of CO2 in the atmosphere, we know that is a physical impossibility. Carbon Dioxide is a colorless and odorless gas:
It also does not reflect or absorb any light within the light spectrum that humans can see. Even if Greta had some special ability to see into the near infrared, the absorption spectrum of CO2 is far removed from the human range of color sensitivity.
But, this claim underscores how bizarre her activism has become, and people seem to want to look the other way instead of questioning her abilities and cognitive understanding of the information she professes to know.
