When carbon emissions appeared to level off from 2014 through 2016, some people were hopeful that industrial civilization just might be able to decouple carbon emissions from economic growth. After all, the world economy had been growing and yet carbon emissions had not grown with it.
Fast forward to today. It turns out that humans are still burning lots of carbon to support economic growth as carbon emissions in 2018 reached a new record. The temporary halt from 2014 through 2016 was primarily due to the rapid replacement of coal-fired power plants with natural gas and renewable energy sources, a trend that by itself cannot solve the climate crisis.
So, once again, policymakers are asking how they can possibly achieve the rapid decline in emissions which the world's scientists say is necessary to avoid catastrophic climate change. The answer is actually simple and extremely painful. They must stop focusing on growth and make an all-out effort to reduce emissions.
