Why Reto Knutti Is the Climate Scientist We Must Listen To

“Silence is an explicit endorsement of oil, gas, and coal—and thus of the destruction of the very foundations of our existence.” – Reto Knutti

There are scientists who conduct their research in quiet laboratories. And there are those who share their findings with the world—in parliaments, boardrooms, and on major stages.

Reto Knutti belongs to the second group. And that’s a good thing. Because what he has to say affects us all.

Reto Knutti – From the physics lab to the UN Climate Summit

Reto Knutti is a climate physicist and full professor of climate physics at ETH Zurich. He earned his Ph.D. in physics in 2002 and spent several years as a postdoctoral fellow and visiting scientist at the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, before joining ETH Zurich as a professor in 2007.

What drove him from the very beginning was not only the question of how the climate works—but also why scientific findings take so long to be incorporated into politics and the economy. It’s a question that continues to occupy his thoughts to this day.

As a lead author and coordinating lead author of the Intergovernmental Panel on Climate Change (IPCC) reports in 2007 and 2013, he presented his findings directly at the UN climate negotiations and in the UN’s structured expert dialogue. He was, in other words, in the very same rooms where the course for global climate policy was set. And he knows exactly what’s happening there—and what isn’t.

200 publications. One of the world’s most-cited climate researchers.

Numbers sometimes speak louder than words. With more than 200 scientific publications, Reto Knutti ranks among the world’s most-cited climate researchers. On ResearchGate, he has over 62,000 citations—a figure that shows just how much his work shapes global climate research.

Reto Knutti is considered one of the world’s leading climate researchers. But he is more than that. He is one of the few top researchers who is also heard—and wants to be heard—outside the scientific community.

“We scientists can’t save the world,” he says himself—but he is convinced that science can make a decisive difference when it is communicated in an understandable way. That is precisely what drives him on every stage.

The man who speaks uncomfortable truths clearly

Reto Knutti is not an alarmist. He is a precise thinker—and that is exactly what makes his statements so effective.

When asked whether what we’re experiencing during heat waves is really climate change, he answers without hesitation: “What we’re seeing now is quite clearly what we’ve been predicting for decades. Hot days are on the rise; heat waves are getting longer, more intense, and more frequent. In Europe, warming is twice as high as the global average.”

And when asked whether researchers must remain neutral: “The notion that you’re neutral if you say nothing is absurd. Silence is explicit approval of oil, gas, and coal—and thus of the destruction of the very foundation of our existence.”

This isn’t scaremongering. It’s plain language based on decades of research.

When hostility arises—and how he deals with it

Anyone who speaks so clearly invites opposition. Even hostility. Reto Knutti knows this—and he has learned to handle it with composure: “You do get attacked now and then when you speak out, but I can live with that. The people who attack me don’t fundamentally disagree with the facts. They feel their worldview and their identity are being undermined. If you understand the psychology behind it, you can actually put it into perspective quite well.”

This composure isn’t indifference. It’s the result of years of experience at the intersection of science, the public sphere, and politics.

On Stage: Building Bridges Between Science and Business

As a speaker and prominent public voice, Reto Knutti regularly engages with political decision-makers, business leaders, and the media on climate, sustainability, and the role of science.

What sets him apart is that he doesn’t just explain what’s happening to the climate. He shows what that means for companies, strategies, and decisions. He talks about risks—but also about opportunities. About what is technologically possible. And about what is still missing politically and economically.

“As a country with plenty of technology, money, education, and innovation, we not only have the best conditions and a great responsibility to combat climate change—we’re also strengthening our position as a business location and promoting long-term energy security.”

This isn’t an environmental sermon. It’s an economic argument.

Who is Reto Knutti the right speaker for?

His keynotes are most effective wherever companies and executives want to understand what climate change specifically means for their business, today and in the coming decades. For board members seeking a well-founded, sober assessment of the situation, without hysteria, but also without sugarcoating.

For conferences that want to ground the topic of sustainability in genuine scientific substance. And for anyone who wants to hear from someone who not only conducts research but also understands how to communicate complex concepts in a way that resonates.

Reto Knutti is proof that science and clarity are not a contradiction. Rather, they are a responsibility.
