Biden apologizes for Trump-era absence on climate, pitching a robust agenda that’s on shaky ground at home

During the Trump administration, the United States, the world’s largest economy, walked away from the Paris climate accord and was virtually invisible at international climate talks. The Biden administration in contrast has shown up in force in Glasgow, with a delegation featuring not only the president, but also a big majority of his Cabinet and a sizable group of career officials. American luminaries such as former president Barack Obama and former vice president Al Gore are also taking part.
