CO₂ levels reach another record high

CO₂ levels just reached another record high. On February 9, 2019, an average daily CO₂ level of 414.27 ppm was recorded at Mauna Loa, Hawaii.

The image below shows hourly (red circles) and daily (yellow circles) averaged CO₂ values from Mauna Loa, Hawaii, for the last 31 days.


As the image shows, average hourly levels well above 414 ppm were recorded on January 21, 2019, but no daily average was recorded for that day. February 9, 2019, was the first time an average daily CO₂ level above 414 ppm was formally recorded and such levels have not been reached earlier over the past 800,000 years, as illustrated by the image below.

CO₂ levels can be expected to keep rising further this year to reach a maximum level in April/May 2019.

How much can CO₂ levels be expected to grow over the next decade? 

A recent Met Office forecast expects annual average CO₂ levels at Mauna Loa to be 2.75 ppm higher in 2019 than in 2018. The image below shows NOAA 1959-2018 CO₂ growth data (black) and uses this Met Office forecast used for 2019 (brown). The growth figures for 2018 and 2019 are spot on a trend that is added in line with an earlier analysis.
