They [Greenpeace] forgot their original purpose and turned into a big, rich bureaucracy, more interested in fund-raising than in saving lives, so I got fed up and quit... they're a bunch of wimps.
This whole controversy about global warming or even evolution - politicians just don't want to take the time to educate themselves.
I do think that the standard media is controlled by the conventional wisdom about global warming. We've come to believe - from reading a lot of articles and talking to a lot of scientists - that there's another side to be heard.
Who will speak for Planet Earth?
In the age of global warming hysteria and the $93 trillion 'Green' New Deal, leftist advocates for more government intervention in the economy under the guise of environmentalism have engaged in a new smear: If you don't buy into climate change hysteria, you're a 'denier' who doesn't care about the environment.
Roger Revelle died of a heart attack three months after the Cosmos story was printed. Oh, how I wish he were still alive today. He might be able to stop this scientific silliness and end the global warming scam. He might well stand beside me as a global warming denier.
Unfortunately the global warming hysteria, as I see it, is driven by politics more than by science.
Do I think that people should in the best of all possible worlds have to go to jail for wanting the US government to pay attention to the warnings of scientists about climate change? Not really. I mean, in a rational world, if all the scientists said, "The worst thing that ever happened is about to happen and here's what you should do to stop it," you would expect any rational system to say, "Oh, sure, OK, let's do something about it." But that's not the world we live in. In the world we live in, you do need people willing to stand up, fight, march and sometimes go to jail.
My travels through physics really are the same urges that make me travel through ecology. They are not really different, except that there is an added dimension of seeing ecological destruction and seeing the very life-support system that makes us survive on this planet being destroyed. That makes me do more than just inquire; it compels me to act and to intervene.
History will judge harshly my Republican colleagues who deny the science of climate change. Similarly, those Democrats who would use climate change as a basis to regulate out of existence the American experience will face the harsh reality that their ideas will fail.
There is a meta discussion, which is the discussion of either good or evil, between freedom and democracy as opposed to totalitarians and murderers. I have decided to take sides with good and against the woke crowd and their stupid interpretation of freedom, out of which comes the account of oppressors versus the oppressed, which is, at bottom, post-Marxism. They have taken the class struggle to other issues—women against men, black against white, the indigenous people’s agenda, the LGBT agenda, the climate agenda, man against nature. The most violent expression of this is the abortion agenda, which is disguised as goodness when in fact it’s a bloody agenda. Unless Europe breaks from that agenda, it will be doomed and disappear in the way that we know it.
Quote from an August 5, 2025 interview.
I can't tell how moving it is to open my email and see a picture of 1,500 Buddhist monks and nuns in the Himalayan kingdom of Ladakh forming a human 350 against the backdrop of the melting glaciers. This is not their fault, and yet they're stepping up to be part of the solution.
The radical Left loves attacking people as anti-science when anyone dares question their computer models on global warming.
I would say the biggest handicap we have right now is some nutcases in our country that don't believe in global warming. I think they are going to change their position because of pressure from individuals, because the evidence of the ravages of global warming is already there.
In Europe, where climate change absolutism is at its strongest, the quasi-religion of greenery in general and the climate change issue in particular have filled the vacuum of organised religion, with reasoned questioning of its mantras regarded as a form of blasphemy.
It was such an amazing experience to be able to spend nine days on a boat with these Greenpeace people. Some of them were scientists and some were crew members working on the ship. Just to hear their stories, like what drew them to Greenpeace in the first place and what they've been through. Every single second of the day they work to save the planet, which makes me as an actor feel quite insignificant.
Saving the world is only a hobby. Most of the time I do nothing.
I was surprised to see how much the mainstream environmental movement hates the ELF.
Wear the badge of environmental radicalism, and you're a citizen automatically under suspicion.
If youre a young person looking at the future of this planet and looking at what is being done right now, and not done, I believe we have reached the stage where it is time for civil disobedience to prevent the construction of new coal plants that do not have carbon capture and sequestration.
If the Pope wants to devote his life to fighting climate change, then he can do so in his personal time. But to promote questionable science as Catholic dogma is ridiculous.
My sense about Greta is that people ought to wait and see and see if she doesn't indeed turn out to be as balanced as we hope and expect she will. But there you are.
We're mathematically past the point where the accumulation of individual actions can add up quickly enough to make a difference. The individual action that actually matters is not being an individual. It's joining together with other people in groups large enough to change the political dynamic around climate change.
The Heartland Institute is about as biased as they come, and it's funded by the likes of Exxon and the Koch brothers. This is the same group that took out billboard space to compare people who understand climate change to the Unabomber.
In the States we've had by far the largest demonstrations in the last few years. The largest civil disobedience actions about anything in US history in the last 30 years have all been centred around the climate.
