BAKU, Azerbaijan — 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. At the United Nations climate talks, in 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. But Earth remains on a path to be 2.7 degrees Celsius warmer than pre-industrial times, according to Climate Action Tracker, a group of scientists and analysts who study government policies and translate that into projections of warming. If emissions are still rising and temperature projections are no longer dropping, people should wonder if the United Nations climate negotiations — known as COP — are doing any good, said Climate Analytics CEO Bill Hare.
