(CNN) New French President Emmanuel Macron trolled President Trump in a televised speech Thursday, condemning the US leader's decision to withdraw from the Paris climate agreement with a call to "make our planet great again".

Speaking first in French, he then switched to English, addressing Trump directly with a play on his campaign slogan to "make America great again." It was the first time a French President has ever given a speech in English from the Elysee Palace.

"On the climate there is no plan B because there is no planet B," he said. This is a "mistake, both for the US and for our planet," he continued.
