What is the CO2 level today?
417.79 ppm Units = parts per million (ppm). Measurement location = Mauna Loa Observatory, Hawaii. Source = NOAA GML. See the tabs below for more info and CO2 readings.
What is the current level of CO2 2021?
416.45 parts per million
The atmospheric level of carbon dioxide has been steadily rising since the 1960’s. In 2021, atmospheric carbon dioxide levels reached a high of 416.45 parts per million, in comparison to 1960 levels which stood at about 316.91 parts per million.
What is the Scripps Keeling Curve?
The Keeling Curve is a daily record of global atmospheric carbon dioxide concentration maintained by Scripps Institution of Oceanography at UC San Diego.
What is a safe CO2 level?
OSHA has established a Permissible Exposure Limit (PEL) for CO2 of 5,000 parts per million (ppm) (0.5% CO2 in air) averaged over an 8-hour work day (time-weighted average orTWA.)
Are CO2 emissions still rising?
Global energy-related carbon dioxide emissions rose by 6% in 2021 to 36.3 billion tonnes, their highest ever level, as the world economy rebounded strongly from the Covid-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis released today.
What was CO2 ppm 1990?
354 parts per million
Analysis of air trapped in ice and snow in Antarctica by NOAA and others demonstrate that after this date, atmospheric carbon dioxide concentrations departed from a relatively stable 280 parts per million observed during the previous 10,000 years, climbing to 354 parts per million in 1990 and 405 parts per million by …
What is Scripps CO2 program?
The Scripps CO2 Program website at http://scrippsco2.ucsd.edu provides access to openly available atmospheric and seawater CO2 concentration data from various sources.
Where are CO2 measured?
the Mauna Loa Observatory
We have confidence that the CO2 measurements made at the Mauna Loa Observatory reflect truth about our global atmosphere. The main reasons for that confidence are: The Observatory near the summit of Mauna Loa, at an altitude of 3400 m, is well situated to measure air masses that are representative of very large areas.
