Watch: Emmanuel Macron Mentions 'Science,' Gets Cheers From Democrats, Hesitation From Some Republicans

French President Emmanuel Macron received standing ovations and overwhelming praise Wednesday from congressional Democrats—and more reluctant approval from many Republicans—when he advocated for the environment and science.

Before members of the House and Senate from both political parties, Macron said: "I believe in building a better future for our children, which requires offering them a planet that is still habitable in 25 years." He was forced to pause momentarily as Democrats flooded the chamber with cheers and applause. By contrast, Republicans on the opposite side hesitated before clapping, while some remained silent.

"Some people," Macron said, seemingly referring to Trump, "think that securing current industries and their jobs is more urgent than transforming our economies to meet the global change of climate change. I hear, I hear these concerns, but we must find a smooth transition to a low carbon economy."

Trump in his 15 months in office has sought to limit federal funding for science and protecting the environment, while rolling back his predecessor Barack Obama's policies that were designed to address pollution and combat climate change.

The topic has been one of several that Trump and Macron do not see eye-to-eye on, and the French president did not sway from his stance in his speech to Congress.

"I believe … that against the threats on the planet, [we have] science," Macron said, drawing loud support from Democrats.

Last June, Trump announced that the United States would withdraw from the 2015 Paris accord to mitigate climate change, an agreement that committed the country to cutting its emissions from 26 to 28 percent below 2005 levels by 2025. The decision drew widespread criticism among Democrats but appeared to appease the GOP as well as conservatives and coal executives.
