TapTechNews reports on May 11, according to the latest Keeling Curve data published by the Mauna Loa Observatory, operated by the National Oceanic and Atmospheric Administration (NOAA) in the United States, the current atmospheric monthly average concentration of carbon dioxide has increased by 4.7 parts per million (ppm) compared to last year, marking a record increase.
The report identifies periodic El Niño events, fossil fuel combustion, and deforestation as the primary drivers behind the rapid growth in global CO2 concentrations.
In June of the previous year, NOAA announced that global carbon dioxide levels had risen to 421ppm, a 50% increase from pre-industrial levels. The updated Keeling Curve now places CO2 levels at 426ppm, the highest recorded in millions of years.
Prior to human civilization's large-scale burning of fossil fuels, which began emitting significant amounts of carbon dioxide into the atmosphere, CO2 levels stood at 280ppm for nearly 6000 years of human civilization.
