The office of U.S. Special Presidential Envoy for Climate John Kerry announced today, Saturday, that he will leave his position in the U.S. administration later on and intends to help President Joe Biden with his campaign. A spokesman for Kerry told Reuters that the former Secretary of State informed his staff of the decision earlier today after speaking with Biden last week. According to a source familiar with the situation, Kerry informed his staff today after talking with Biden on Wednesday. The source, who requested anonymity, stated that the U.S. administration has not yet made a decision regarding who may succeed Kerry. Axios was the first to report this news today, mentioning that Kerry (80 years old) will leave his position later this winter and intends to assist Biden with his campaign. Kerry played a significant role in mediating efforts for the 2015 Paris Climate Agreement, in addition to the agreement made by the UAE during the United Nations climate change conference (COP28) held in Dubai in December, calling for a shift from fossil fuels. Kerry previously served in the Senate from Massachusetts and was the Democratic party's presidential nominee in 2004, losing to former Republican President George W. Bush.
