Summary
This year, scientists are forecasting that atmospheric concentrations of carbon dioxide will likely peak at around 417 ppm, signifying that for every 1 million molecules of gas in the atmosphere, 417 are carbon dioxide.And with that, humanity will be charging into wholly uncharted territory."For millions of years, we haven't had an atmosphere with a chemical composition as it is right now,” said Martin Siegert, co-director of the Grantham Institute at Imperial College London.The concentration of carbon dioxide is closely watched as an indicator of how humans are influencing Earth's climate.
