Really?Can it be reversed if it is happening? Many people say no. Concurrently, it would take a global effort and many emerging economies are the biggest culprits. Try getting the Indians and Chinese to reduce their emissions. Not going to happen. So where are we really? I think this all really boils down to more western self flagellation.

Energy Shocks

China, the world’s largest emitter of greenhouse gases, is determined to rebalance its energy mix, and incorporate more clean energy. That determination is reflected in the money it put into renewable energy last year, dwarfing spending by the next biggest investor, the US.
Last year nearly half of the world’s new renewable energy investment of $279.8 billion (pdf, p.11) came from China, according to a report published April 5 by Bloomberg New Energy Finance, and the sustainable energy finance center run by the United Nations Environment Program and the Frankfurt School of Finance and Management. China’s investment in renewable energy—excluding large hydro projects—rose 30% compared with 2016, and was more than three times of that of the US, whose investment in the sector dropped 6% from 2016 to $40.5 billion last year.
China first overtook the US in new renewable energy investment in 2009 (p.14), but the gap between the two only amounted to $14 billion at that time.
Together, the “big three” developing economies, China, India, and Brazil, accounted for a record 63% of global investment in renewable energy in 2017, noted the report (p.20). Developing countries first surpassed developed country investment in renewables in 2015, but fell back in 2016.
At this rate, China will be a clean economy before we are. And India is finally starting down the same path. Of the present amount of GHGs in the Earth's atmosphere, the developed nations have contributed a far bigger share than the developing nations. And all of us should be helping the third world's poverty stricken nations to develop sun and wind power.
