Matt speaks with Harvard historian of science Naomi Oreskes about the long-standing scientific consensus on climate change and the political forces undermining it. Oreskes explains how Congress understood climate risks as early as the 1960s, why the EPA’s endangerment finding remains crucial, and how powerful interests have attacked science as climate change shifted from prediction to observable reality. The conversation highlights threats to academic freedom and the growing political pressure on universities.

Guest Bio:

Naomi Oreskes is a world-renowned historian of science, author, and Harvard University professor whose work has shaped global understanding of climate change and climate denial. With groundbreaking research on how scientific consensus forms—and how powerful interests attempt to undermine it—Oreskes has become one of the most influential voices defending science in the public sphere.

She is the author of several acclaimed books, including Merchants of Doubt and The Big Myth, and her writing has appeared in major scientific journals and international publications. Oreskes frequently testifies before lawmakers, contributes to climate policy debates, and speaks worldwide about the urgent need to protect both the planet and the integrity of science itself.

In this week’s episode of  A Climate Change, host Matt Mattern welcomes comedian and writer Bill Kessler for a spirited, no-filter take on the intersection of climate politics, policy, and everyday life. Blending wit with insight, they dissect the week’s environmental headlines, from viral AI spectacles to the deeper economic and moral choices shaping our planet’s future.

Matt and Bill unpack the $700 million clean energy project cancellations, exploring what that means for America’s battery manufacturing, job creation, and energy independence. They examine the lawsuits around Cancer Alley, where weakened EPA air pollution standards are hitting vulnerable communities hardest, and talk about the human cost behind those policy shifts.

From public transport funding shortfalls to the environmental price of ultra-processed foods, the conversation connects personal choices with systemic change and lands on practical optimism. Bill’s closing thought? Go buy a two-year-old electric vehicle; it’s smart economics and smart for the planet.

It’s a grounded, funny, and thought-provoking exchange that reminds us that humour and hope still belong in the climate conversation.

Fact: According to an IRENA report on Reuters from mid-July, over 90% of new renewable projects are now cheaper than fossil fuel alternatives. Solar is 41% cheaper, and onshore wind is 53% cheaper than fossil fuel energy. The consumers are speaking up, and market dynamics are pushing the growth of renewables. In this episode of A Climate Change, host Matt Mattern speaks with Dr. Gernot Wagner, climate economist at Columbia Business School, and author of Climate Shock, to unpack how economics and policy are reshaping the global energy transition. 

They discuss why renewables like wind and solar are now cheaper than fossil fuels despite political headwinds, how carbon pricing systems, from California to Uruguay, drive emissions cuts, and why electrifying buildings offers the fastest decarbonisation gains. 

Dr. Wagner also explores the promise of green hydrogen for industry, the rise of small modular nuclear reactors, and the strategic need for domestic solar manufacturing. This insightful conversation reveals how market forces and smart policy design can accelerate the shift to cleaner, more affordable, and resilient energy systems.

Fact: According to a December 2024 report by WRI, 75% of greenhouse gases and 90% of CO2 emissions are linked to extracting and burning fossil fuels. While sustainability measures like emission control and renewables focus on the demand side of the equation, the real high-impact change lies in measures to control the supply side. This week, Matt sits down with Tzeporah Berman, Chair of the Fossil Fuel Non-Proliferation Treaty Initiative and one of Time magazine’s Top 100 Climate Impact leaders. Together, they explore a groundbreaking global movement to phase out fossil fuel production through international cooperation and equitable transition strategies.

Berman reveals how 17 countries, 3,000+ organisations, and 101 Nobel laureates have joined the call for a treaty to manage the fair and just wind-down of oil, gas, and coal. She explains why focusing solely on emissions isn’t enough, and how supply-side policies could finally turn the tide on climate change.

This conversation offers a bold, practical roadmap for ending fossil fuel dependence while empowering nations to embrace renewable energy and energy security.
