Al Gore, the former vice president and controversial environmental activist — along with an array of celebrities, elected officials and others — are launching a climate change-related broadcast on Monday, December 3, called “24 Hours of Reality: Protect Our Planet, Protect Ourselves.”

Their pronounced goal is to “take bold and ambitious action to ensure that future generations can live long, healthy lives full of opportunity and promise,” according to a press release out today.

“Our health depends on the health of the planet,” said Gore in the release from the Climate Reality Project.

“The climate crisis is not an abstract issue; it has direct impacts on us and the people we love the most,” he continued in the statement. “I’m looking forward to exploring the climate and health connection on this year’s ’24 Hours’ broadcast,” he also said in part.

Those joining Gore include Sting, Moby, David Crosby, Grateful Dead founding member Bob Weir, and others.

Also scheduled to participate in the star-studded climate event include Jeff Goldblum (shown above left), Jaden Smith, Téa Leoni, Jonathan Scott, Claire Danes, Mandy Patinkin, Cody Simpson, and Bill Nye (above center).

The celebrity-crammed production will air live from Los Angeles. It will aim to highlight “unique regional health impacts and celebrat[e] local, national, and international efforts to implement meaningful climate solutions.”

The broadcast, to be televised worldwide in 125-plus countries, will also stream live on the group’s website.

Gore founded The Climate Reality Project in 2014.

Here’s the trouble with much of his supreme confidence on these issues, however: His film “An Inconvenient Truth” became a smash hit before Gore’s reputation was muddied. Since that first film’s release, Gore has shown himself to be something of an environmental hypocrite.

Gore not only lives a millionaire’s lifestyle that puts most middle-Americans to shame, but his behavior has suggested someone who will say one thing yet do another. “Inconvenient Truth” was criticized for being partly filmed on a private jet. Gore also came under scrutiny when he sold Current TV to Al Jazeera and oil tycoons for millions upon millions of dollars.

Still, the group he founded in 2014 says it is “working to catalyze a global solution to the climate crisis by making urgent action a necessity across every level of society” and “spreading the truth about the climate crisis and building popular support for clean energy solutions.”

The former vice president also made waves last week when he commented on the National Climate Assessment report that was released by the White House the day after Thanksgiving — and ripped into the president.

Gore said in a statement on his website addressed to President Donald Trump, “Mr. President, the majority of Americans are deeply concerned about the climate crisis and demand action. Even as local leaders are responding in the wake of fires and storms, national leaders must summon the will to respond urgently to the dire warnings of this report with bold solutions.”

He claimed the president may have been trying to “hide the truth” — and said his timing of the report’s release was intentionally chosen for Black Friday to “bury this critical U.S. assessment of the climate crisis.”

Al Gore’s last environmental documentary was called “An Inconvenient Sequel: Truth to Power.” Check out its trailer below:
