Australian Olympian Sam Fricker amassed over 1.2 million TikTok followers thanks to the Tokyo Games this year.
Today, the 19-year-old diver uses his platform to raise awareness of the increasing amount of carbon dioxide (CO2) in Earth’s atmosphere.
Fricker and UNSW Professor Chris Turney explained a graph of atmospheric CO2 levels in a video posted to TikTok on Wednesday.
âIt was the last ice age 18,000 years ago and that’s the amount of CO2 in the air over the years,â Fricker said in the video, pointing to the graph.
Fricker’s CO2 emissions video came as dozens of countries pledged to phase out coal at COP26 – but Australia was not one of them.
Prof Turney then explained a marked improvement in the graph, which he attributed to industrialization.
âIt was industrialization and we’re here at 410 so well above natural variability,â Prof Turney said.
Professor Turney said the amount of CO2 in the atmosphere is 410 parts per million (PPM), which is how it is typically measured.
The global concentration of CO2 in the atmosphere was around 278 ppm during the pre-industrial era of 1750 to 1800, according to the Scripps CO2 program.
Atmospheric carbon dioxide peaked for 2021 in May at a monthly average of 419 parts per million (ppm), which is more than 50% above pre-industrial levels.
