Obama Calls Paris Climate Pact 'Best Chance' to Save the Planet

U.S. President Barack Obama on Saturday hailed the landmark climate accord reached in Paris as strong and historic, calling it the best chance to save the planet from the effects of global climate change.

"Today the American people can be proud because this historic agreement is a tribute to American leadership. Over the past seven years, we've transformed the United States into the global leader in fighting climate change," Obama said.

He said the accord shows what is possible when the world stands as one, adding:  "This agreement represents the best chance we have to save the one planet that we've got."

Speaking at the White House hours after the deal was completed, Obama said that "no agreement is perfect, including this one," and that negotiations that involve nearly 200 nations are always challenging.

"Even if all the initial targets set in Paris are met, we'll only be part of the way there when it comes to reducing carbon from the atmosphere," Obama added.
