Scientists are increasingly finding the fingerprints of climate change in droughts, storms and heatwaves.

A review of 102 scientific papers over the past three years, published Tuesday, found 73 concluded that climate change made extreme weather events more intense or likely.

London-based think tank Energy and Climate Intelligence Unit presented its review on the sidelines of the U.N. climate talks in Katowice, Poland.

The group’s director, Richard Black, said the strongest link between climate change and weather was found in heatwaves, such as the one in Europe this summer.

Adele Thomas of Berlin-based research group Climate Analytics said scientists’ growing ability to attribute extreme weather to climate change could have important consequences for international discussions about financial compensation for countries suffering loss and damage from manmade global warming.

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.
