“The rate of CO2 growth over the last decade is 100 to 200 times faster than what the Earth experienced during the transition from the last Ice Age” – Pieter Tans, NOAA
This chart displays annual increases (as opposed to totals) of carbon dioxide in the atmosphere.
The United States National Oceanic and Atmospheric Administration (NOAA) has issued more grim news on the global warming front: Atmospheric Carbon Dioxide (CO2) is continuing to rise, and has jumped sharply the past two years. The rate of increase has also accelerated:
According to NOAA’s press release:
Carbon dioxide levels measured at NOAA’s Mauna Loa Baseline Atmospheric Observatory rose by 3 parts per million to 405.1 parts per million (ppm) in 2016, an increase that matched the record jump observed in 2015.
The two-year, 6-ppm surge in the greenhouse gas between 2015 and 2017 is unprecedented in the observatory’s 59-year record. And, it was a record fifth consecutive year that carbon dioxide (CO2) rose by 2 ppm or greater, said Pieter Tans, lead scientist of NOAA’s Global Greenhouse Gas Reference Network.
Also from the NOAA release: Globally averaged CO2 levels passed 400 ppm in 2015 — a 43-percent increase over pre-industrial levels. In February 2017, CO2 levels at Mauna Loa had already climbed to 406.42 ppm.
Meanwhile, the nations of the earth make promises and the Trump Administration prepares the way for total climate denier takeover.
