Preliminary data shows that methane emissions jumped in 2020 by the largest amount since systematic record-keeping began decades ago. And despite a dip in polluting activities due to the pandemic, concentration of carbon dioxide in the atmosphere rose to its highest level in 3.6 million years.
The National Oceanic and Atmospheric Administration (NOAA) said that global methane concentrations shot up by 14.67 parts per billion (ppb) in 2020, the largest annual increase ever recorded, and a sharp increase from the 9.74 ppb rise in 2019. The data is an ominous sign that the world is badly off track in terms of reaching its climate goals.
