As the outrage over President Trump’s withdrawal from the Paris Climate Agreement grows, many foreign leaders haven’t been shy about voicing their disappointment. Taking the lead in speaking out is French President Emmanuel Macron, who released a powerful speech — in English.

Macron posted the 3-minute video to his official Twitter account this Thursday:

From Vox:

Knowing an American audience would be watching and listening, he went straight for the national security implications of climate change. “If we do nothing, our children will know a war of migrations, of wars, of shortage. A dangerous world,” the French leader said. In other words: This ain’t just a science-y thing. This a real security problem, as even the Pentagon noted in a major report.

In his unprecedented direct message to American “scientists, engineers, entrepreneurs, committed citizens” who oppose Trump’s decision, Macron said: “I want to say that they will find in France a second homeland. I call on them: ’Come, work and here with us, to work together on concrete solutions for our climate.’”
