Koldioxid (CO2) förbrukas och syre (O2) bildas. Idag är koncentrationen av CO2 ca 380 ppm (Wikipedia) (parts per million eller miljondelar)

Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (412 ppm) by volume, having risen from pre-industrial levels of 280 ppm. As of 2001, measured atmospheric concentrations of carbon dioxide were 100 ppm higher than pre-industrial levels.

Atmospheric CO2 concentrations (ppm) derived from in situ air measurements at Mauna Loa, Observatory, Hawaii. Credits: Dr. Pieter Tans ( NOAA/ESRL ), Dr. Ralph Keeling, S. J. Walker, S. C. Piper and A. F. Bollenbacher ( Scripps Institution of Oceanography ) Indoor carbon dioxide can also impact our decision-making and problem-solving skills. The Lawrence Berkeley National Laboratory uncovered a connection between carbon dioxide concentrations and cognitive and working ability. Most activities dipped slightly when exposed to 1000 ppm indoor CO2 levels, but the cognitive abilities across a spectrum of functions tanked at 2500 ppm. PPM. Z Wikipedie, otevřené encyklopedie.

CO2 measurements are made by two independent CO2 monitoring programs (NOAA and Scripps) at the Mauna Loa Observatory in Hawaii, about 3400 metres above sea level. Explore the tabs below where you will see daily CO2 charts and related links.

The measurements collected at Mauna Loa Observatory show a steady increase in mean atmospheric CO. 2 concentration from 313 parts per million by volume ( ppmv) in March 1958 to 406 ppmv in November 2018, with a current increase of 2.48 ± 0.26 (mean ± 2 std dev) ppmv CO. 2 per year. Parts-per-million (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO2 means that if you could count a million gas molecules, 1,000 of them would be of carbon dioxide and 999,000 molecules would be some other gases. Termiä ppm käytetään usein HTP-arvojen eli haitalliseksi tunnettujen pitoisuuksien ilmoittamiseen. Mineraalien pitoisuus maaperässä voidaan ilmoittaa ppm:inä.

Grove - CO2 & Temperature & Humidity Sensor (SCD30) The Grove - CO2 & Temperature & Humidity Sensor (SCD30) is a high precision carbon dioxide sensor, which is based on Sensirion SCD30. The measuring range of this sensor is 0 ppm-40'000 ppm, and the measurement accuracy can reach to ±(30 ppm + 3%) between 400ppm to 10'000ppm.
