(ORDO NEWS) — About a third of the total methane emissions came from the extraction and use of fossil fuels.
Methane emissions globally hit record highs in 2021. Maximum concentrations are recorded for the second year in a row, Reuters reports citing data from the US National Oceanic and Atmospheric Administration (NOAA).
According to the report, global methane emissions reached 640 million tons in 2021, while carbon dioxide emissions over the same period are estimated at 36 billion tons.
According to scientists, about 30% of methane emissions last year came from the extraction and use of fossil fuels.
NOAA noted that methane and CO2 remain the two main greenhouse gases. At the same time, methane molecules have a stronger heating effect, but decay in the atmosphere within two decades, while carbon dioxide remains in the air for centuries.
According to the head of NOAA Rick Spinrad, reducing methane emissions should be an important tool to slow global warming and counteract the effects of climate change.
