Dozens of nations pledged on Saturday to do more to protect nature and overhaul farming at the COP26 U.N. climate talks, amid misgivings about past failures.

"Nature and climate are interlinked, and both our people and our surroundings are facing the very real impacts of rising temperatures,” Alok Sharma, the British president of the Glasgow summit, told a news conference.
