Carbon Dioxide Levels Are Highest in Human History
Humans pumped 36 billion tons of the gas into the atmosphere in 2021
The amount of planet-warming carbon dioxide in the atmosphere broke a record in May, continuing its relentless climb, scientists said Friday. It is now 50 percent higher than the preindustrial average, before humans began the widespread burning of oil, gas and coal in the late 19th century.
There is more carbon dioxide in the atmosphere now than at any time in at least 4 million years, National Oceanic and Atmospheric Administration officials said.
The concentration of the gas reached nearly 421 parts per million in May, the peak for the year, as power plants, vehicles, farms and other sources around the world continued to pump huge amounts of carbon dioxide into the atmosphere. Emissions totaled 36.3 billion tons in 2021, the highest level in history.
