Ökningstakten av koldioxidhalten (CO2) i atmosfären de senaste 70 åren är nära 100 gånger så stor som efter slutet av den senaste istiden. Utifrån observationer har så kraftiga förändringar av koldioxidhalten i atmosfären aldrig tidigare skett. CO2.Earth connects the general public with the latest data and information for stabilizing earth's atmosphere, climate and living environments. For example, the mole fraction of carbon dioxide has increased from 280 ppm to 415 ppm, or 120 ppm over modern pre-industrial levels. The first 30 ppm increase took place in about 200 years, from the start of the Industrial Revolution to 1958; however the next 90 ppm increase took place within 56 years, from 1958 to 2014. 2021-04-05 · This is more than what had happened naturally over a 20,000 year period (from the Last Glacial Maximum to 1850, from 185 ppm to 280 ppm). The time series below shows global distribution and variation of the concentration of mid-tropospheric carbon dioxide in parts per million (ppm).

CO2, pH, and carbonate alkalinity) can be used to determine the CO 2 system • Traditionally, pH and alkalinity were measured • Now we can also use ΣCO 2 and P CO2 to better constrain calculations, improving accuracy

Atmospheric CO2 concentration surpassed 400 ppm in 2016, and the average concentration in 2019 was more than 411 ppm. Source: Based on figure by  Nov 23, 2020 “We breached the global threshold of 400 parts per million in 2015. And just four years later, we crossed 410 ppm.

About CO2… Formula: concentration (ppm) = 24.45 x concentration (mg/m 3) ÷ molecular weight For example: 50 mg/m 3 of NH 3 (17.03 g/mol) 24.45 x 100 ppm / 17.03 = 71.785ppm In 2013, CO 2 levels surpassed 400 ppm for the first time in recorded history. This recent relentless rise in CO 2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air. 2020-06-10 2017-06-30 2021-04-05 A Representative Concentration Pathway (RCP) is a greenhouse gas concentration (not emissions) trajectory adopted by the IPCC.
