KATOWICE, Poland (Reuters) - Delegates from nearly 200 nations on Sunday began two weeks of talks to tackle deep political divisions at the most important U.N. meeting on global warming since the landmark 2015 Paris deal to shift away from fossil fuels.

Expectations are low that negotiations in Katowice, at the heart of Poland's coal region, will fully resolve concerns laid out in reports over recent weeks on the severity of rising greenhouse gas emissions.
