In the table of atmospheric concentrations (see slide 3). fG,CO2 = 3.9 x 10-4 moles CO2/total moles. = 390 x 10-6 moles CO2/total moles. = 390 ppm. This can Top climate scientists and the prestigious UK Royal Society say we must DECREASE atmospheric CO2 concentration from the present 390 ppm to 300- 350 ppm 4 Jun 2015 The concentration of CO2 in the atmosphere is increasing at a rate of about 1-2 parts per million (ppm) per year and it is currently around 390 Atmospheric CO2. Over the last 100 years, concentration of atmospheric. Carbon dioxide (CO2) has increased from about 280 ppm to 390 ppm and the majority Atmospheric CO2: Atmospheric concentrations of carbon dioxide (CO2) have increased from. 280 ppm in pre-industrial times to 390 ppm today and are 30 Oct 2017 in 2016, with CO2 at 403.3 ± 0.1 ppm, CH4 at 1 853 ± 2 ppb(3) 390.

Med nuvarande utsläpp fortsätter halten att stiga med åtminstone 2 ppm per år. ca 180 ppm under istider, ca 280 ppm under mellanistider och nu över 390 ppm en nivå om ca 400 ppm CO2 ” samt ”att vid en stabilisering på 450 ppm CO2e

The ONLY credible atmospheric CO2 real measurments we have are the Mauna Loa Records, that start at 315 ppm in 1957-8, and now are at 390 ppm in 2011 That is a 23.8 % increase in 53 years. So there’s proxy data that says it might once have been as low as 280 ppm; but there is also proxy evidence that it once was over 7000 ppm.

Ökad CO2-koncentration inomhus och i uppehållsrum anses tyda på otillräcklig ventilation. Gasen sprids snabbt i dåligt ventilerade utrymmen.
