Greenhouse gas concentrations further increased in 2022, finds analysis of global satellite data
Preliminary analyses of global satellite data by environmental researchers at the University of Bremen show that atmospheric concentrations of the two important greenhouse gases carbon dioxide (CO2) and methane (CH4) continued to rise sharply in 2022. The increase in both gases is similar to that of previous years. However, the increase in methane does not reach the record levels of 2020 and 2021.

What began as a theory in the 1890s — that industrial emissions of carbon dioxide could increase global temperatures — had progressed to a scientific fact a century later. Scientists across a range of disciplines are studying the impact of the still-growing concentration of carbon dioxide and other so-called “greenhouse gases” in the atmosphere as they call for industrial and governmental policies to slow, then halt, the warming of the planet.
