Oil company Exxon Mobil today told President* Trump that it's probably not a great idea to withdraw from the Paris treaty on reducing carbon emissions. When the oil industry, the global poster boy of dirty energy, makes that kind of comment, you should know you've gone too far.
Fact in the matter is that very few, if any, new jobs will be created by this. The coal industry in the US is dying due to a lack of demand, not because of harsh CO2 regulations, and if it should somehow reinvent itself, a significant number of people who are currently employed to design and implement alternative energy solutions like wind and solar energy might lose their high-tech jobs if low-tech coal becomes an option again. The effect could be both a net loss of jobs and increased CO2 emission. Nice move, Mr. President.
