13 May 2019 A study in April used computer models to confirm that carbon dioxide levels today are the highest they have been in three million years. The study

CO2 and Past Climates As a point of reference, pre-industrial CO2 levels were around 280 parts per million (ppm) and today, we stand at 410ppm. The most distant period in time for which we have estimated CO2 levels is around the Ordovician period, 500 million years ago. At the time, atmospheric CO2 concentration was at a whopping 3000 to 9000 ppm!

The record of 421 parts per million reached Saturday is just a single point and occurred as CO2 levels are nearing their yearly peak. But the levels over the past two months, of more than 417 parts

All farmers should consider CO2 as a nutrient. 2013-12-03 Ned, "if CO2 were to go over 2000 ppm today most of that ice would (eventually) be gone." Agreed. And I certainly am not questioning the role of solar irradiance. But the geological proof that ice once existed at our South Pole -- striated bedrock among other unmistakable features -- would still be there. Back then, CO2 levels were around 315 ppm (already an increase from preindustrial levels of about 280 ppm), but they have grown steadily, first crossing the 400 ppm threshold in May 2013.

Atmospheric carbon dioxide measured at Mauna Loa Observatory reached a seasonal peak of 417.1 parts per million for 2020 in May, the highest monthly reading ever recorded, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today. The safe level of carbon dioxide in the atmosphere is 350 parts per million.

Carbon Dioxide Levels and Your Health 250 – 350 ppm + background (normal) outdoor air level; 350- 1,000 ppm – typical level found in occupied spaces with good air exchange.
