"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).
Carbon dioxide levels rose by more than two parts per million (ppm) for the 11th consecutive year: the highest sustained rate of CO2 increases since monitoring began 65 years ago. Before 2013, scientists had never recorded three consecutive years of such high CO2 growth.
Atmospheric CO2 is now 50% higher than pre-industrial levels."
