Greenhouse gas emissions rose at ‘alarming’ rate last year, US data shows

Noaa report shows rapid increase in atmospheric levels of carbon dioxide, methane and nitrous oxide

Record temperatures, devastating floods and superstorms are causing death and destruction across the planet but humans are failing to cut greenhouse gas emissions fueling the climate emergency, new US data shows.

Atmospheric levels of carbon dioxide (CO₂), methane and nitrous oxide - the greenhouse gases emitted by human activity that are the most significant contributors to global heating - continued to increase rapidly during 2022, according to the National Oceanic and Atmospheric Administration (Noaa).
