Carbon mitigation or climate catastrophe

EARLIER this year, in September, the United Nations reflected the growing anxieties of the world by sponsoring the leaders’ summit on climate change, the central issue of human survival in the 21st century.

A few days from now, we will know if the UN’s anxieties have been taken to heart by delegates to the 20th annual session of the Conference of the Parties (COP 20) in Lima, Peru. They will continue the negotiations toward a new global climate agreement that, all hope, will be approved in the COP21 in December 2015 in Paris, entering into force by 2020.
