Jun 26, 2017 At 399 ppm, India matches the world in atmospheric carbon dioxide levels · Satellite data show concentrations highest over Uttar Pradesh and May 13, 2019 According to data from the Mauna Loa Observatory in Hawaii, the concentration of CO2 in the atmosphere is over 415 parts per million (ppm), The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years. Over the past 171 years, human activities have raised atmospheric concentrations of CO 2 by 48% above pre-industrial levels found in 1850.

Ppm co2 in the atmosphere

In 2013, CO 2 levels surpassed 400 ppm for the first time in recorded history. This recent relentless rise in CO 2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air. 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!
