Annual increases in carbon dioxide emissions – Noah
Madrid, April 8. (European Press) –
Global levels of the three most important human-caused greenhouse gases (Carbon dioxide (CO2), methane and nitrous oxide) It continued to increase steadily through 2023,
According to NOAA scientists, an increase in three heat-trapping gases was recorded in air samples collected by NOAA’s Global Monitoring Laboratory (GML) in 2023. It was not as high as standard jumps It has been observed in recent years, These are in line with the strong increases observed over the past decade.
The average global surface concentration of carbon dioxide over the 12 months of 2023 was 419.3 ppm, an increase of 2.8 ppm over the year. This was the 12th consecutive year that CO2 rose by more than 2 ppm, the highest sustained rate of CO2 increases over 65 years of observational record. Three consecutive years of carbon dioxide growth of 2 ppm or more had not been observed in NOAA monitoring records before 2014. Carbon dioxide in the atmosphere is now more than 50% higher than pre-industrial levels.
“The increase in 2023 is the third largest in the past decade, most likely a result of the continued increase in carbon dioxide emissions from fossil fuels, along with an increase in fire emissions possibly as a result of the transition of La Niña to El Niño,” he added. He said It’s a statement Shen Lan, a CIRES (Cooperative Institute for Research in Environmental Science) scientist who leads GML’s effort to compile data from NOAA’s Global Greenhouse Gas Reference Network to track global greenhouse gas trends.
Methane in the atmosphere Less abundant than carbon dioxide but more powerful at trapping heat in the atmosphere, rising to an average of 1922.6 parts per billion (ppb). The increase in methane in 2023 compared to 2022 was 10.9 ppb, lower than the record growth rates recorded in 2020 (15.2 ppb), 2021 (18 ppb), and 2022 (13.2 ppb), but They remain the fifth highest rates since the renewed growth of methane. Methane gas began to enter the atmosphere in 2007 It is now more than 160% higher than its pre-industrial revolution level.
In 2023, levels of nitrous oxide, the third most important human-caused greenhouse gas, increased by one part per billion to 336.7 parts per billion. The two years with the greatest growth since 2000 occurred in 2020 (1.3 ppb) and 2021 (1.3 ppb). Increases in atmospheric nitrous oxide over the past few decades are primarily due to the use of nitrogen fertilizers and manure resulting from the expansion and intensification of agriculture. Nitrous oxide concentrations are 25% higher than the pre-industrial level of 270 parts per billion.
