For nearly a million years, carbon dioxide levels in the atmosphere have maintained an average of about 280 ppm, not going above 300 ppm or below 160 ppm. Global warming (and cooling) trends have ...
Heat-trapping carbon dioxide levels in the air peaked in May 2021, in amounts nearly 50% higher than when the industrial age began and they are growing at a record fast rate, scientists reported ...
Scripps tracks the daily atmospheric CO2 levels of Earth, using data from the Mauna Loa Observatory in Hawaii to produce a graph that is known as the Keeling Curve.
Carbon dioxide levels in the atmosphere ... from the continuous rampant burning of fossil fuels as well as El Niño conditions making the planet's ability to absorb CO2 more difficult. This graph ...

Carbon dioxide is released into the atmosphere. CO2 levels peak every year in May , just as spring begins in the Northern Hemisphere before plants reach full bloom and absorb the gas.
Carbon dioxide levels in Earth’s atmosphere exceed 415 ppm for the first time in human history - Mic
In continued bad news for the environment, carbon dioxide levels in Earth's atmosphere have reached a concerning new milestone — and it definitely isn't anything to celebrate. For the first time ...
A misleading bar chart comparing modern carbon dioxide (CO2) levels to those millions of years before humans existed ignores a large CO2 increase during the human era that has changed the climate ...
They’ve been measuring carbon dioxide levels continuously since 1958 at that location, but ice cores and other data show that it’s not just the highest carbon dioxide has been in 61 years of data.
According to data from the Mauna Loa Observatory in Hawaii, the concentration of CO2 in the atmosphere is over 415 parts per million (ppm), far higher than at any point in the last 800,000 years ...
