President Obama praised his administration on Saturday for the progress it has made combating climate change over the past seven-and-a-half years, but pressed Americans to step up their resolve to save the environment in his final six months in office.

“There’s still much more to do. But there’s no doubt that America has become a global leader in the fight against climate change,” Obama said in the weekly White House address. “And if we keep pushing, and leading the world in the right direction, there’s no doubt that, together, we can leave a better, cleaner, safer future for our children.”
