Question

Did you know? Atmospheric CO2 rose from 280 ppm in 1750 (pre-industrial) to 422 ppm in 2024 — a roughly 50% increase. The last time CO2 was this high was 4 million years ago, in the Pliocene, when sea levels were 17 metres higher than today.

Accepted Answer

Atmospheric CO2 rose from 280 ppm in 1750 (pre-industrial) to 422 ppm in 2024 — a roughly 50% increase. The last time CO2 was this high was 4 million years ago, in the Pliocene, when sea levels were 17 metres higher than today.

CO2 in de atmosfeer steeg van 280 ppm in 1750 (preindustrieel) tot 422 ppm in 2024 — een toename van ~50%. De laatste keer dat CO2 zo hoog stond was 4 miljoen jaar geleden, in het Plioceen, toen de zeespiegel 17 meter hoger lag dan vandaag.
