When more than two dozen world leaders deliver remarks at the United Nations' annual climate conference on Wednesday, many are likely to detail their nations' firsthand experience with the catastrophic weather that has come with climate change.

The major focus of the negotiations is climate finance, which is rich nations trying to help poor countries pay for transitioning their economies away from fossil fuels.

At the United Nations climate talks, hosted in Baku, Azerbaijan, nations are trying to set new targets to cut emissions of heat-trapping gases and figure out how much rich nations will pay to help the world with that task.

For the third straight year, efforts to fight climate change haven't lowered projections for how hot the world is likely to get — even as countries gather for another round of talks to curb warming, according to an analysis Thursday.
