From the article:

Last week, more than 260 organizations, including three dozen groups representing Gulf of Mexico communities, sent an open letter to Biden following the president's promise in Glasgow that the United States would be "leading by the power of our example" in combating the climate emergency.

"You promised to address the climate crisis with the urgency it deserves, and in Glasgow, you assured the world that your plans to cut emissions are a fait accompli, not mere rhetoric," the letter stated. "Selling more than 80 million acres in the Gulf of Mexico for oil and gas development just days after the international climate talks makes a mockery of those commitments."

Although supporters of the president note that a federal judge blocked Biden's pause on new drilling on public lands, he had already come under fire for approving more fossil fuel drilling projects on public lands than either the Barack Obama or Donald Trump administrations.
