Carbon dioxide in Earth's atmosphere
It is one of several greenhouse gases in the atmosphere of Earth. The current global average concentration of carbon dioxide (CO 2) in the atmosphere is 421 ppm as of May 2022 (0.04%). [1] This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century.
Understanding the basics of carbon dioxide
Recently, NOAA announced that levels of carbon dioxide measured at NOAA's Mauna Loa Atmospheric Baseline Observatory (MLO) surged to a seasonal peak of just under 427 parts per million (ppm) in May.

How Charles Keeling Measured the Rise of Carbon Dioxide
When Keeling died in 2005, global CO 2 levels had risen to 380 ppm. This year, on April 3, 2021, we surpassed 420 ppm for the first time in recorded history. These measurements were both taken at the Mauna Loa Observatory, Keeling's legacy. Yet, sixty-three years after its establishment, human-induced climate change is still a topic of ...

State dependence of CO2 forcing and its implications for climate
Climate sensitivity is formally defined as the change in the global mean surface temperature required to restore radiative equilibrium in response to a doubling of CO 2 concentration (ΔT 2×CO2).It is the most widely used metric to quantify the susceptibility of the climate to an externally forced change, i.e., ΔT 2×CO2 = -RF 2×CO2 /λ, where the radiative damping (λ, which is expressed ...
