Obama: Pollution from China Will Put South Florida Under Water

Obama: "You can't build a border wall" to stop climate change (CBS News)

Negotiators from around the world are now in the middle of two weeks of talks in Paris, trying to reach an agreement to limit global warming.

Last month, President Obama pledged a $3 billion U.S. contribution to an international fund for developing countries - such as India -- to cope with the effects of climate change.

"Keep in mind, these are pledges over a number of years. And this is in our interest. Let's take a country like India that's got over a billion people. If they are to develop, using let's say, coal as their main way of generating electricity, with a billion people... you're looking at an amount of carbon that would mean South Florida's gone, because the ocean's would have risen too high," Mr. Obama said. "You can't build a border wall when it comes to carbon emissions or global temperatures or the oceans. We've got to make sure that people have incentives to work with us."
