Nivåerna av CO2 i dag är även de på en historiskt låg nivå för 20 000 år sedan när den senaste istiden började gå mot sitt slut var CO2 halten 180 ppm vilket endast är 30 ppm över den nivå som växtligheten klarar. Under 150 ppm kan inte fotosyntesen upprätthållas och växterna kvävs till döds. Most fish and invertebrate species can live comfortably and safely in water that has a CO2 content of 30 ppm (mg/l). However, that toxicity threshold can change drastically, depending on the levels of dissolved oxygen in the water.

It is an accurate, low-cost solution for OEMs who want to integrate CO2 sensing into applications like modified atmosphere packaging (MAP), occupancy detection, or rapid data sampling for process monitoring. 2017-06-07 After 30 years of measurements, the ocean carbon community is realizing that tracking human-induced changes in the ocean is not as easy as they thought it would be. It wasn’t a mere matter of measuring changes in carbon concentrations in the ocean over time because the natural carbon cycle in the ocean turned out to be a lot more variable than they imagined. 2019-05-14 2010-01-24 2021-04-06 Planta simulando o ambiente do Carbonífero,onde havia 35% de oxigênio e 4000 ppm de co2.
