The team of physicists was investigating the possibility of using radioactive decay rates to generate random numbers, since the rate is constant but the emission of individual atoms is unpredictable, it seemed like a perfect fit.

Stacking up the numbers, he realised that human activities were adding CO2 to the atmosphere in a quantity and rate equivalent to all natural processes of absorption or emission of the gas.
