Hot and Indigestible Carbon Dioxide

Last July, the concentration of CO2 in the atmosphere was 408 ppm. In the last 400 million years, a CO2 concentration 300 ppm was considered high. Therefore the high concentration of CO2 we are experiencing now was never reached in the last half billion year. This increase will for sure have an impact on how plants will be growing in the next decades.
