U.N. Climate Boffins Sweat The Details In Poland

In Poland, high-level negotiators are working away at what is billed as the most important U.N. conference on the environment, since the Paris 2015 agreement on climate change. Reuters reports the challenge is to meet a year-end deadline to agree to a rule book to limit global warming. Delegates said a major issue was how to reassure developing countries that richer nations would deliver on promises to help pay to shift to a lower carbon economy.
