"Indeed, a recent report showed how none of the world’s top industries would be profitable if they paid for the true cost of natural capital. Granted, there has been some progress in the global decarbonization effort, but to date this has occurred on the fringes and in the absence of any enforceable targets to limit the total amount of atmospheric CO2."

"The Paris Agreement in 2015 saw the international community agree to limit warming to within 2°C. The Hansen team argue that the much safer approach is to reduce atmospheric concentrations of CO₂ from the current annual average of more than 400ppm (parts per million) back to 1980s levels of 350ppm. This is a moderately more ambitious goal than the aspiration announced in Paris to further attempt to limit warming to no more than 1.5°C. Many climate scientists and policymakers believe that either the 2°C or 1.5°C limits will only be possible with negative emissions because the international community will be unable to make the required reductions in time.
