World leaders met online for a second day on Friday to discuss global climate change issues.
During the summit, which included a total of 17 huge figures, the United States president was the only one pictured wearing a mask.
Biden was sat alone in front of a blue background, wearing a suit, tie and black face mask.
The president has since been mocked online for his decision to wear a face covering during the virtual conference.
“The entire world is laughing at us,” one Twitter user wrote.
Another slammed “he’s the dumb one there,” while someone slammed him as an “absolute embarrassment.”
