M 15 162b Earth Atmosphere Carbon Dioxide Future Role In Global Warming Simulation 20151109.
The National Oceanic and Atmospheric Administration said measurements of carbon dioxide (CO2) has peaked in May, averaged 419 parts per million at Mauna Loa, Hawaii. The new record is 1.82 parts per million higher than in May 2020 and 50 percent higher than the stable pre-industrial levels of 280 parts per million.
NOAA reported that it is not only the highest level in human history, but also all the way back to the beginning of human history 4.1 million to 4.5 million years ago. Back then, the sea level was about 78 feet higher than today, the average temperature was 7 degrees Fahrenheit higher than in pre-industrial times. Another study indicates that the area that once areas of the Arctic are now tundra.
Pieter Tans, a senior scientist with NOAA’s Global Monitoring Laboratory said: “We are adding roughly 40 billion metric tons of CO2 pollution to the atmosphere per year. That is a mountain of carbon that we dig up out of the Earth, burn and release into the atmosphere as CO2 – year after year.”
“If we want to avoid catastrophic climate change, the highest priority must be to reduce CO2 pollution to zero at the earliest possible date,” he added.

That's the 2021 peak for atmospheric carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory – the highest level in 63 years, according to scientists from NOAA, @Scripps_Ocean & @UCSanDiego. https://t.co/MrBh0UEHaY pic.twitter.com/xFbZElaCue
