In some ways, 400 ppm is just a number, another milestone that we are blasting past at a rate that is now exceeding 2 ppm per year. Over time, this number takes on greater weight. It brings home the fact that fossil fuel combustion, land use practices, and human activities have increased the CO2 concentration in Earth’s atmosphere by more the May 2020 hit a record high, 417 parts per million (ppm) carbon dioxide as measured at the Mauna Loa Observatory, which has continually measured CO2 in the atmosphere since 1958. Scripps noted that this puts atmospheric CO2 levels 50% higher than they were just prior to the industrial revolution. Scripps also noted that the amount of CO2 accumulating in the atmosphere is accelerating.

Jag beräknar att vi i slutet av 2016 går vi över gränsen 400 ppm CO2 för gott. Packa väskan och spänn fast bältet. 😉 /Martin. PS. Nivån 400 ppm är inte mer magisk än tex 398,12 eller 401,37.

A 50% increase on this (417 ppm) is predicted to be exceeded by the 26 Jan 2017 Atmospheric concentrations of CO2 are now above 400 parts per million year- round globally. Atmospheric concentrations of CO2 surpassed 400 As of. 2010, atmospheric CO2 is now at about 393 ppm! How fast is the amount of Carbon Dioxide (CO2) increasing in the earth's atmosphere?

The time series below shows global distribution and variation of the concentration of mid-tropospheric carbon dioxide in parts per million (ppm).
