Several of the Democratic hopefuls counted climate change as one of the major threats to the country, but most were short on specifics of how they'd confront it.

Washington Gov. Jay Inslee said he was surprised to be the only candidate who would make climate change "their top priority" and "the organizing principle" of their administration.

It's the only way, he said, "we can save ourselves, our children, our grandchildren and save life on this planet."

Inslee also got in a dig at President Donald Trump, countering his statement that power-generating windmills cause cancer by saying they "cause jobs."

Beside saying the key to fighting climate change was to "bring everybody together to find a solution to the challenges we face," former Rep. Beto O'Rourke of Texas got a bit more specific when he said he'd also fund resiliency projects in Miami, Houston and other "places on the front lines of climate change today."

Massachusetts Sen. Elizabeth Warren tied the environment to the economy by saying fossil fuel companies are "doing great" while the rest of us are "watching climate change bear down on us."

On his first day as president, former Housing and Urban Development Secretary Julian Castro said he'd sign an executive order to reenter the Paris Accord on climate Change.
