Now we are living in a 400 ppm CO2 world...
September 2016 is a major milestone for the world’s climate change history - according to Mauna Loa CO2 program at the Scripps Institution of Oceanography, the monthly value of atmospheric carbon dioxide failed to drop below 400 parts per million. It means, that 2016 will be the year that CO2 officially passed the symbolic 400 ppm mark, never to return below it in our lifetimes.
September is usually the month when carbon dioxide is at its lowest after a summer, when plants in the northern hemisphere are growing and absorbing CO2.
The carbon dioxide we’ve already emitted to the atmosphere has warmed the planet by about 1°C since the start of the industrial revolution, what is pretty close to 1.5°C warming threshold, a key temperature level in Paris Agreement on climate.
