Barack Obama has penned a parting missive for his successor, Donny Trump. It comes in the form of a paper now published in the journal Science entitled, "The irreversible momentum of clean energy."
The idea seems to be to demonstrate to the reader (assuming Trump can indeed read - and there's some doubt about that) that transitioning to clean energy from fossil fuels will facilitate rather than impede economic growth.
This “decoupling” of energy sector emissions and economic growth should put to rest the argument that combatting climate change requires accepting lower growth or a lower standard of living. In fact, although this decoupling is most pronounced in the United States, evidence that economies can grow while emissions do not is emerging around the world.
At the same time, evidence is mounting that any economic strategy that ignores carbon pollution will impose tremendous costs to the global economy and will result in fewer jobs and less economic growth over the long term.
The full paper, in PDF format, can be found here. It's short enough that even Trump should be able to digest it.
