2015-12-01 · In the 800,000 years before industrialization, the CO 2 level hovered around 280 ppm. But the 20th century saw a sharp increase that continues today. The CO 2 level is now around 400 ppm.

Before the Industrial Revolution started in the mid-1700s, the global average amount of carbon dioxide was about 280 ppm. The amount of carbon dioxide in the atmosphere (raspberry line) has increased along with human emissions (blue line) since the start of the Industrial Revolution in 1750.

These conditions yielded a detection limit of 0.022% (220 ppm) when measured empirically, which was close to the theoretical value and only eight times lower than that of a faster, more simplistic macro The peak CO2 measurement of 2014 was just shy of 402 ppm in May. While the 400 ppm mark is somewhat symbolic (as the increase in warming between 399 ppm and 400 ppm is small), it is a large 2019-03-01 2013-05-22 2013-06-01 2016-04-13 2019-05-13 7.3.1 Overview of the Global Carbon Cycle 7.3.1.1 The Natural Carbon Cycle . Over millions of years, CO 2 is removed from the atmosphere through weathering by silicate rocks and through burial in marine sediments of carbon fixed by marine plants (e.g., Berner, 1998). Burning fossil fuels returns carbon captured by plants in Earth’s geological history to the atmosphere. When did carbon dioxide in the atmosphere reach 380 ppm and thus well exceed its natural range of 180 to 280 ppm? in the past two decades.
