Arnold Schwarzenegger, Emmanuel Macron shoot video selfie about climate change

"We will deliver together to make the planet great again," Macron says.

"I'm here with President Macron, we're talking about environmental issues and a green future," Schwarzenegger says in the video, before passing the phone to Macron.

"And now we will deliver together to make the planet great again," adds Macron, an obvious nod to Trump's "Make American Great Again" slogan. For the duration of the video, a banner across it reads, "With President Macron, a great leader!"

Macron also retweeted Schwarzenegger's selfie video, writing, "The let's # MakeOurPlanetGreatAgain project takes form. Glad to work on it with @ schwarzenegger."

Prior to arriving in the French capital, Schwarzenegger delivered a speech on climate change at the Austrian World Summit.
