GLASGOW, Scotland (AP) -- The generation of young people who will inherit a warmer future is telling the generation that caused carbon pollution to clean up its mess -- from both inside and outside United Nations climate talks.\nThere are more young people than ever roaming the halls at the talks. That's in addition to the thousands of mostly young protesters carrying signs outside at a Fridays For Future rally some blocks from the fenced-off pavilion. Young people are being seen and celebrated in Glasgow. But they fear they're not being heard.\nUnited Nations Secretary-General Antonio Guterres and numerous other leaders have credited youth activism for reinvigorating the world's fight to curb climate change. The UN's theme Friday, in fact, was youth involvement, with leaders talking about how important young people are in the battle to keep the world from getting too hot and wild from extreme weather.\nBut even on a day dedicated to young people, the midday highlights were a speech by 73-year-old former U.S. Vice President Al Gore and a news conference by 77-year-old John Kerry, the U.S. climate envoy.
