Known for his iconic roles as Indiana Jones and Han Solo, actor Harrison Ford put on his activist hat with a speech at the 2018 Global Climate Action Summit in which his chastised “anti-science” political leaders, warning climate change is threatening humanity.

Ford, in the words of the Daily Beast,”offered a grim outlook for humanity” if people continue to ignore claims that mankind is changing the climate.

“If we don’t change the path that we’re on today, the future of humanity is at stake,” a solemn Ford declared Thursday at the event in San Francisco.

“While you work to meet the challenge of climate change, I beg of you — don’t forget nature. Because today, the destruction of nature accounts for more global emissions than all the cars and trucks in the world.”

Ford called climate change a “monster” and encouraged everyone to “shut off phones, roll up sleeves, and kick this monster’s ass.”

Last November, the actor slammed the Trump administration’s environmental policies while accepting an award from environmental nonprofit Conservation International.

He said at the time that the greatest threat is not climate change, it’s “that we’ve got people in charge of important sh– who don’t believe in science.”

On Thursday he took aim at Trump again.

“For God’s sake, stop electing leaders who don’t believe in science,” Ford said.

As WND reported earlier this week, the Washington Post published an editorial asserting the commander-in-chief is “complicit” in the storm battering the Carolinas.

Trump, the Post editorial said Tuesday night as the massive hurricane approached, “plays down humans’ role in increasing the risks, and he continues to dismantle efforts to address those risks.”

30 years of ‘falsified’ predictions

WND reported last month that 30 years have gone by since the “opening salvo” in the movement claiming mankind is causing catastrophic global warming, and the dire predictions of drastic temperature and sea-level rises “are well on their way to being falsified – and by a lot, not a little,” an energy expert contended.

Rob Bradley Jr., the CEO and founder of the Institute for Energy Research, pointed out claims made by NASA climate scientist James Hansen and Al Gore along with the “opening salvo,” the June 24, 1988, prediction by Philip Shabecoff in a New York Times article titled “Global Warming Has Begun.”

Shabecoff wrote that if “the current pace of the buildup of these gases continues, the effect is likely to be a warming of 3 to 9 degrees Fahrenheit [between now and] the year 2025 to 2050.” He also predicted a consequent rise in sea levels of “one to four feet by the middle of the next century.”

Bradley, who has testified before the U.S. Congress as one of the nation’s leading experts on the history and regulation of energy markets, argued that the mid-point of Shabecoff’s predicted warming would be six degrees.

“At the thirty-year mark, how is it looking?” Bradley asked. “The increase is about one degree – and largely holding (the much-discussed ‘pause’ or ‘warming hiatus’).”

He also pointed out that the world has naturally warmed since the end of the Little Ice Age, which is “a good thing if climate economists are to be believed.”

Regarding sea-level rise, Bradley wrote, “the exaggeration appears greater.”

“Both before and after the 1980s, decadal sea-level rise has been a few inches. And it has not been appreciably accelerating,” he noted.

Shabecoff was reporting a model based on the predictions of Hansen and Michael Oppenheimer.

Bradley wrote that the predictions “constitute yet another exaggerated Malthusian scare, joining those of the population bomb (Paul Ehrlich), resource exhaustion (Club of Rome), Peak Oil (M. King Hubbert), and global cooling (John Holdren).”
