Leaders return to Poland for final push at UN climate talks

KATOWICE, Poland (AP) — National leaders and ministers are preparing for the final stretch of U.N. climate talks, with just days left to break through thorny issues that diplomats have struggled to resolve.

U.N. climate chief Patricia Espinosa urged delegates Tuesday to show a "spirit of unity" through the end of the week.

Almost 200 countries are gathered at the Dec. 2-14 meeting in Katowice, Poland, to finalize the rules of the 2015 Paris accord on curbing global warming.

The Intergovernmental Panel on Climate Change says governments need to act soon to keep temperature increases to 1.5 degrees Celsius (2.7 Fahrenheit).

The talks are also meant to push countries to commit to more ambitious targets for greenhouse gas emission reductions.

Poor countries, meanwhile, want assurances on financial support to tackle climate change.
