In an article for the journal Science, President Obama says that although the understanding of the impact of climate change is increasingly and disturbingly clear, “there is still debate about the proper course for US policy – a debate that is very much on display during the current presidential transition”.
That is almost his only acknowledgment of President-elect Donald Trump’s declared belief that climate change is a hoax, invented by the Chinese.
Clean energy economy
“But putting near-term politics aside,” he writes, “the mounting economic and scientific evidence leave me confident that trends toward a clean energy economy that have emerged during my presidency will continue and that the economic opportunity for our country to harness that trend will only grow.”
First of these is that between 2008 and 2015, the US economy grew by 10% while carbon dioxide emissions from the energy sector fell by 9.5%, an outcome that “should put to rest the argument that combating climate change requires accepting lower growth or a lower standard of living”.
Renewable energy costs fell dramatically during his years in office: 41% for wind, 54% for rooftop solar photovoltaics and 64% for big solar-power installations. Clean energy now attracts twice as much global capital as fossil fuels.
President Obama also believes that businesses now understand that reducing emissions works for the benefit of business – it cuts costs for consumers and delivers returns to shareholders.
It also matters to the workforce: 2.2 million Americans are now employed in the design, installation and manufacture of energy-efficiency products and services, while 1.1 million Americans are employed in producing fossil fuels and generating electric power with those fuels.
