Compared to former geologic times, Earth’s atmosphere is “CO2 impoverished.” Atmospheric CO 2 concentrations (ppm) derived from flask air samples taken aboard aircraft at 700, 500 and 300 hPa over North Pacific, Alaska, and Arctic Ocean from April 1958 through December 1961, spanning 11° 54'N to 86° 18'N latitude, and 105° 18'W to 166° 12'W longitude. CO2 poisoning, however, is very rare. Carbon Dioxide Levels and Your Health 250 – 350 ppm + background (normal) outdoor air level; 350- 1,000 ppm – typical level found in occupied spaces with good air exchange. 1,000 – 2,000 ppm – level associated with complaints of drowsiness and poor air. I första spalten kan vi läsa: We ﬁnd that the average gradients of fossil fuel CO2 in the lower 1200m of the atmosphere are close to 15 ppm at a 12 km×12 km horizontal resolution. Här står “15 ppm”, vilket är vad som sedan spritts.

Så från noll ppm CO2 i atmosfären till 280 ppm som det var för 120 år sedan så ökade Vi har ökat på med 135 ppm CO2 i atmosfären plus andra växthusgaser men värmen har bara Climate history - What could happen with CO2 > 500 ppm?

Däremot bör nivån inte ligga över 1000 ppm mer än korta perioder. Det innebär att medelvärdet över en dag inte heller får ligga över 1000 ppm. Vår Skolväska innehåller både co2-, temperatur- och luftfuktighetsloggers samt mjukvara för att kunna göra relevanta mätningar av inomhusmiljön.

CO2 levels are updated daily with data directly from NOAA's science lab on the slopes of Moana Loa volcano on the Big Island of Hawaii. Atmospheric carbon dioxide measurements have been collected here daily since 1959. Pre-1959 data comes from ice core data taken from Antarctica. CO2 concentration at the Mauna Loa Observatory reached a daily record of 421.21 Parts Per Million (PPM) on April 3.
