The amount of heat-trapping carbon dioxide in the atmosphere has shot past a key milestone -- 50% higher than pre-industrial times -- & is at levels not seen since millions of years ago when Earth was a hothouse ocean-inundated planet, scientists said.

The National Oceanic and Atmospheric Administration announced Friday, June 3, 2022, that the amount of carbon dioxide in the atmosphere in May averaged 421 parts per million, more than 50% higher than pre-industrial levels. The NOAA said carbon dioxide levels in the air in May have reached a point last known when Earth was 7 degrees hotter, millions of years ago.
Levels of the gas continue to rise, when they need to be falling, scientists say. This year’s carbon dioxide level is“The world is trying to reduce emissions, and you just don’t see it. In other words, if you’re measuring the atmosphere, you’re not seeing anything happening right now in terms of change,” said NOAA climate scientist Pieter Tans, who tracks global greenhouse gas emissions for the agency.
University of Illinois climate scientist Donald Wuebbles said without cuts in carbon pollution “we will see ever more damaging levels of climate change, more heat waves, more flooding, more droughts, more large storms and higher sea levels.”
