Countries have made scant progress in curbing their greenhouse gas emissions over the past year, keeping the planet on track for dangerous levels of warming this century, according to a new report published Thursday.

The report by the Climate Action Tracker, a research group, estimates that the climate and energy policies currently pursued by governments around the world would cause global temperatures to rise roughly 2.7 degrees Celsius, or 4.9 degrees Fahrenheit, above preindustrial levels by 2100.

That estimate of future warming has barely budged for three years now, the group said.

“We are clearly failing to bend the curve,” said Sofia Gonzales-Zuñiga, a climate policy specialist at Climate Analytics, a science and policy organization, and a lead author of the report. “As the world edges closer to these dangerous climate thresholds, the need for immediate, stronger action to reverse this trend becomes ever more urgent.”

The study was issued during the United Nations climate summit in Baku, Azerbaijan, where diplomats and world leaders have gathered to discuss how to raise trillions of dollars to cope with rising global temperatures.

Under the 2015 Paris Agreement, world leaders had pledged to hold total global warming to “well below” 2 degrees Celsius, and preferably closer to 1.5 degrees Celsius, to limit the risks from climate catastrophes. Scientists have said that every fraction of a degree of warming brings greater risks from deadly heat waves, wildfires, drought, storms and species extinction.
