MIAMI — Hillary Clinton on Tuesday joined Al Gore, a co-recipient of the 2007 Nobel Peace Prize for his work on climate change, to discuss an issue that has deeply divided the Democratic and Republican parties and directly impacted Florida’s southern coast.

The Democratic nominee pointed to the recent devastating effects of Hurricane Matthew here, which she said were exacerbated by global climate change, as evidence the threat is very real.

“Our next president will either step up our efforts to protect our planet . . . or in the alternative, we will be dragged backwards and our whole future will be put at risk,” Clinton told a crowd of about 1,600 at Miami Dade College.

The campaign stop doubled as a voter-registration drive less than a month away from Election Day.

Clinton also commended Gore, her husband’s former vice president, for his dedication to fighting climate conditions that have led to rising waters and increased tropical diseases. She suggested he could have a role in her White House.

“I can’t wait to have Al Gore advising me when I am president of the United States,” Clinton said.

She attacked Republican nominee Donald Trump’s position on climate change and noted that he has spoken of it as a hoax.

She said he opposes the Paris climate agreement to slow the rise of greenhouse gases.

“The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive,” Trump tweeted in 2012.

The Republican tempered his comments earlier this year and said climate change won’t have a “devastating impact.”

Trump’s campaign earlier this year criticized Clinton’s stance as an “extreme, reckless anti-energy agenda” intended to appease donors who will do away with American jobs.

In Miami, Gore gave a good-humored nod to his razor-thin loss to President George W. Bush in 2000 in Florida.

“Your vote really, really, really counts,” he quipped. “You can consider me as Exhibit A of that.”

The supportive crowd chanted, “You won! You won!”

A federal judge extended the deadline for voter registration in the Sunshine State to Wednesday from Tuesday in light of evacuations and other complications linked to Hurricane Matthew — a decision viewed as a victory for the state Democratic Party, which sued after GOP Gov. Rick Scott opposed moving the date.

At the rally, in a reminder of the sexual abuse allegations against Bill Clinton that were made fresh by Trump at the recent debate, a protester disrupted Hillary Clinton’s remarks by shouting about the former president and was escorted out.

Also Tuesday, WikiLeaks released an apparent email exchange between top Clinton campaign staff that Trump’s team said showed “collusion” with the U.S. Department of Justice under President Barack Obama in an investigation into Clinton’s use of a private email server as secretary of state.

The WikiLeaks site published what it said was a hacked May 2015 email from Clinton spokesman Brian Fallon telling his colleagues that “DOJ folks inform me there is a status hearing on this case this morning.”

Trump senior communications adviser Jason Miller said in a statement that the apparent leak shows a “level of collusion which calls into question the entire investigation into her private server.” Trump tweeted that the email showed “disgraceful behavior” on Clinton’s part.

Clinton director of communications Jennifer Palmieri said aboard the campaign plane, “Court documents are public information. . . . The court hearing is public information.”
