Mr Biden, 79, made a speech on Wednesday in which he dubbed climate change a "clear and present danger".
Illustrating his point, he referred to the COP26 climate conference, held in Glasgow in October 2021.
But he mistakenly referred to the Scottish city as being in England, in a gaffe that raised eyebrows in the UK.
He said: "Folks, with American leadership back on climate, I was able to bring more world leaders together than — we got 100 nations together to agree that — at the major conference in Glasgow, England."

To his credit, Mr Biden quickly corrected his error as he made the speech in Somerset, Massachusetts.
He clarified: "I mean, Scotland — to change the emissions policies we had."
It was not the only gaffe he made in the speech, though.
Mr Biden said he "has cancer" as he spoke about emissions from oil refineries near his home in Claymont, Delaware.
The US President said: “That’s why I, and so damn many other people I grew up with, have cancer.
"And why, for the longest time, Delaware had the highest cancer rate in the nation.”
White House spokesman Andrew Bates was quick to clarify his comments, referring to a tweet which said Mr Biden had “non-melanoma skin cancers” removed before he took office.
Mr Biden's health summary was published in 2021. It reads: "It is well-established that President Biden did spend a good deal of time in the sun in his youth.
“He has had several localised, non-melanoma skin cancers removed with Mohs surgery before he started his presidency.
“These lesions were completely excised, with clear margins.

"Total body skin exam was performed for dermatologic surveillance.
“Several small areas of actinic change were treated with liquid nitrogen cryotherapy, but there are no areas suspicious for skin cancer at this time.
“No biopsies were required.”
It remains unclear as to why Mr Biden used the present tense during his speech.
