NEW YORK — Yelling that the future and their lives depend on ending fossil fuels, tens of thousands of protesters on Sunday kicked off a week where leaders will try once again to curb climate change primarily caused by coal, oil and natural gas.

       But protesters say it’s not going to be enough. And they aimed their wrath directly at U.S. President Joe Biden, urging him to stop approving new oil and gas projects, phase out current ones and declare a climate emergency with larger executive powers.

       “We hold the power of the people, the power you need to win this election,” 17-year-old Emma Buretta of Brooklyn and the youth protest group Fridays for Future said. “If you want to win in 2024, if you do not want the blood of my generation to be on your hands, end fossil fuels.”
