“Finish the Fight”: Climate Legend Bill McKibben Calls for Mᴀssive Nationwide Protests This Saturday

The voice on the other end of the line carried decades of experience and a quiet urgency that cut through the noise of daily headlines.

Bill McKibben, one of America’s most respected climate voices and co-founder of Third Act, sat down for a conversation that felt less like an interview and more like a warning from someone who has spent a lifetime watching history unfold.

“This is completely abnormal,” he said, his tone steady but filled with gravity.
“There have been presidents we didn’t like before, but there’s never been anything like this — just sheer craziness.”

McKibben, author of the groundbreaking book *The End of Nature* — widely considered the first major work for a general audience about climate change — has spent decades fighting for justice, the environment, and basic human decency.
Now, at this moment in American history, he is sounding an alarm that cannot be ignored.

He pointed to a presidency that has launched wars without explanation, attacked core democratic insтιтutions, and created a level of chaos that feels unprecedented even to those who have lived through some of the darkest chapters of the 20th and 21st centuries.

“The last No Kings Day so ticked off the president that he put out that video of him flying an airplane above America, dropping excrement on the heads of protesters,” McKibben recalled with a mix of disbelief and resolve.
“If anybody thinks this doesn’t matter, it matters in the biggest possible way.”

He paused, letting the weight of that image settle.

McKibben’s message is simple yet urgent: this Saturday’s nationwide “No Kings” protests represent a critical moment for ordinary Americans to reclaim their voice and their agency.

“Next Saturday is really important,” he emphasized.
“When we did No Kings 2, it was a huge day of action. Since then, President Trump and his administration have sH๏τ and murdered two Americans in the streets of Minnesota, and that launched two wars. This one’s going to be much, much, much bigger still.”

Organizers are closing in on numbers that could rival the first Earth Day in 1970, when 20 million Americans took to the streets and fundamentally changed environmental policy for a generation.

“We need everybody out,” McKibben said.
“We need to be making it clear just how tired we are of this incredibly wearying and exhausting presidency.”

He spoke directly to those who feel overwhelmed or unsure what they can do.

“Look, when we did No Kings, it was a kind of clever way of talking about this, but by this point he’s acting in exactly the ways that kings and authoritarian leaders around the world act. A king is someone who sends his soldiers off to war without explaining to anybody why and without asking anybody if it’s okay. Just on his say-so, we’re suddenly fighting a war that no American can explain and that, according to the polling, almost no Americans want.”

McKibben’s call is especially powerful because it comes from someone who has spent his life building movements against seemingly impossible odds.

He knows what it feels like to stand against moneyed interests, entrenched power, and public apathy.
He also knows what it feels like when millions finally decide to show up.

“One of the reasons that we’re so intent on organizing older Americans,” he explained, “is that they have a kind of baseline against which to judge this.”

Third Act, the organization he co-founded, mobilizes people over the age of 60 for action on climate and racial justice.
In recent weeks, McKibben has been filming a series of videos with some of the oldest members — people in their 90s who have lived through more than a third of America’s 250-year history.

“What they’re saying over and over again is, this is completely abnormal,” he shared.
“They’ve been around for a long time. They’ve seen presidents they didn’t like, but there’s never been anything like this — just sheer craziness.”

He recounted stories from these elders: a woman whose sister died of polio and who was among the first to receive the vaccine, now furious that the next generation of infants is being tossed into the immunological unknown.
Another who simply cannot believe the speed at which basic norms and insтιтutions are being dismantled.

“The craziness of this moment is what’s driving people out,” McKibben said.

For those who have never protested before, he made it as simple as possible.

“This one really is easy. These are very gentle and lovely protests, and you’ll be out in your community. You go to nokings.org to find out where one of the 3,000 protests nearest to you is and what time it’ll be. Write yourself a sign if you want, but just show up. Be with other people. Your body in the streets this day is your testament to your sense of the world.”

He offered a special invitation to older Americans who might feel more comfortable marching with their peers.

“If you are an older person and feel more comfortable in the company of other older people in this work, go to thirdact.org. We’ll be having lots and lots of people marching behind big banners that say Elders Against Authoritarianism. We’ve lived a long time. We haven’t seen anything like this, and we do not intend to pᴀss it on to our children. We want America back — improved.”

McKibben was clear that showing up matters on multiple levels.

“There is value in your body being out there being counted. There is value in those aerial sH๏τs of tens of thousands of people, hundreds of thousands of people. We still look at those Earth Day pictures from 1970. And you know who still looks at pictures of crowds? It’s Donald Trump, pretending that his inauguration got all kinds of people out when nobody came. There’s nobody in this country who pays more attention to crowd size than Donald Trump. So let’s do him a solid and show what it looks like when people really, really care.”

He believes 2026 will be defined not just by opposition to Trump’s agenda, but by the enthusiasm and determination of those who oppose it.

“It’s not just that most Americans oppose what he’s doing. It’s that the people who oppose it, oppose it with an enthusiasm of history that far outmatches whoever is still left out there pretending they support him or just unable to get over the idea that they made a mistake and unwilling to admit it.”

McKibben’s voice carried both warning and hope.

“People shouldn’t have to spend their weekends out protesting. We should be allowed to go for a hike in the woods or see our grandkids or whatever it is. But this is the country that we currently inhabit. If we want the old country back — well, take your grandkid out with you to the protest. It’ll be good for them. They’ll have a good time. It’ll be history. It’ll be a picture they look back at for a long time.”

He ended with a direct challenge to every listener.

“Your job is not to sit on the sidelines wondering what to do. Your job is to show up. Be counted. Let the world see that millions of Americans still believe in decency, in democracy, and in a future worth fighting for.”

As the interview concluded, McKibben left no doubt about the stakes.

“This isn’t the end of the work, but it’s the start of the work to get rid of, to thwart this just by this point crazy authoritarian presidency unlike anything we’ve ever seen before.”

The message was unmistakable.

This Saturday, the streets will speak.
Millions of voices.
Millions of bodies.
A clear declaration that America refuses to surrender its soul to authoritarianism.

The question now is simple:
Will you be one of them?
