Dr. Lomborg said: “Paris is being sold as the summit where we can help ‘heal the planet’ and ‘save the world’. It is no such thing. If all nations keep all their promises, temperatures will be cut by just 0.05°C (0.09°F). Even if every government on the planet not only keeps every Paris promise, reduces all emissions by 2030, and shifts no emissions to other countries, but also keeps these emission reductions throughout the rest of the century, temperatures will be reduced by just 0.17°C (0.3°F) by the year 2100. And let’s be clear, that is very optimistic.
