Greenhouse gas concentrations rise significantly in 2022

(ORDO NEWS) — The concentration of greenhouse gases in 2022 continued to increase. This was reported by the press service of the University of Bremen.

Tracking the dynamics of greenhouse gas accumulation began in 2002, when the SCIAMACHY instrument began operating on the European environmental satellite ENVISAT.

At the moment, it is complemented by the Japanese GOSAT and GOSAT-2, as well as the American OCO-2.

The satellites measure the vertically averaged ratio of a mixture of carbon dioxide CO2 and methane CH4. Data are presented in parts per million (ppm) for CO2 and parts per billion (ppb) for CH4.

As a result, it turned out that the amount of methane increased by 11.8 parts per billion in 2022, and carbon dioxide – by 2.1 parts per million. CO2 levels increase almost uniformly – unlike methane.

Between 2000 and 2006, methane concentrations were on average stable. However, since 2007, the content of methane began to grow again, especially at a high rate in recent years.

Record levels of growth were recorded in 2020 and 2021, likely due to an increase in methane emissions during the COVID-19 epidemic.
