Joseph R. Biden Jr. was sworn in as the 46th president of the United States on Wednesday, January 20, 2021. Minutes before, Kamala D. Harris took the oath of office to become the first woman, the first Black American, and the first South Asian American to be elected vice president. Biden is at work to address the climate crisis and has taken steps to bring America back into the Paris Agreement. “By rejoining the crucial Agreement that we were instrumental in achieving, we’ll again lead the world in addressing the existential threat of climate change. America has been tested and we have come out stronger for it. We will repair our alliances and engage with the world once again. Not to meet yesterday’s challenges, but today’s and tomorrow’s. We will lead not merely by the example of our power but by the power of our example. We will be a strong and trusted partner for peace, progress, and security.” | Inaugural Address by President Joseph R. Biden, Jr., January 20, 2021
