Climate Change Debate: Bjørn Lomborg and Andrew Revkin

Introduction

> The interview underscored the moral implications of making fossil fuels too expensive for people to afford, emphasizing the importance of ensuring access to good lives for all.

> It highlighted the power of nuanced conversations in bridging the gap between climate change dismissives and the alarmed, aiming not to convince but to enlighten each other with shared insights and wisdom.

Politics of climate change

> Climate change isn't a black-and-white issue; "there's a spectrum of belief" that has shifted over decades. It's no longer just about whether it's real or a hoax, but rather what kind of energy future we want and the complexities that come with it. There’s an uncomfortable reality we must face: old energy norms are colliding with a growing understanding of how our planet's systems work.

> "We're building vulnerability to climate hazards" at the same time the climate is changing. It’s not just about greenhouse gases; our decisions about where and how we build communities play a critical role in our collective risk. Understanding that vulnerability is a human-made construct opens up new avenues for action.

> It's essential to nuance the conversation around climate, moving beyond alarmism or denial. When we think the world is ending soon, we overlook practical solutions that can be implemented now. "This isn’t about tipping the balance back toward the center," but rather about finding constructive opportunities to tackle the multifaceted challenges we're facing, which extend far beyond just climate.

Greta Thunberg

> Greta Thunberg’s alarmism is crucial in raising awareness about climate change, as she captures the urgency of the crisis facing younger generations who feel they have little opportunity for a future. However, while her approach fosters discussion, it’s vital to steer the conversation towards actionable solutions instead of simply breeding fear: "Alarm for the sake of getting attention or clicks... is not any more valuable than watching an action movie."

> Moreover, as climate dialogue often gravitates towards extremes for media engagement, it’s important to shift focus back to practical steps that individuals and communities can undertake. Emphasizing the real problems, like air pollution or rebuilding strategies post-natural disasters, can lead to meaningful change, rather than getting sidetracked by popular narratives that sound engaging but distract from the actual solutions we need: "The fun of battle... creates progress."

Electric cars

> I have mixed feelings about electric cars. They are fantastic in many ways—they can be more efficient, eventually cheaper, and they push forward innovative technologies. However, they're often seen as a panacea for climate change, which they are not. The production of their batteries is highly polluting and contributes significantly to CO2 emissions. Additionally, many electric cars are secondary vehicles, driven less frequently than primary gasoline cars, and heavily subsidized for wealthier individuals rather than for the greater good.

> What we really need is a focus on the most impactful and cost-effective strategies. Instead of heavily subsidizing expensive electric cars in wealthy countries, we should be looking at affordable electric motorcycles in developing nations where they can drastically improve air quality and CO2 emissions for a fraction of the cost. It's essential to allocate our resources effectively to maximize the benefits for both the environment and societal equity.

Economy

> "The conversation should not just be about whether climate change is real; it's about 'what can we actually do?' This means looking at effective policies rather than getting caught up in the moral high ground. For instance, while electric cars are often championed, they currently provide limited carbon savings at a high cost, and smarter solutions like fracking offer a more effective way to reduce emissions—albeit not perfect."

> "We must rethink our focus. It's not enough to obsess over eliminating carbon emissions if we neglect to reduce vulnerability to climate disasters. Instead of just aiming for zero emissions, we should prioritize practical strategies like smarter urban planning to protect communities from hurricanes and flooding, which might be a far more impactful approach."

Journalism

> The pivotal moment in my journey came in 2006 when I realized "the scariest science" is not just climate data, but how our minds grapple with the issue. Social dynamics, rather than just climate systems, shape political attitudes, rendering climate change a "complex" and often ignored reality.

> I've cultivated a wariness around "narrative capture," recognizing that both science and media can fall into self-sustaining narratives. "You’re on a train and everyone’s getting on," which can blind us to crucial contrary indications, limiting our understanding of the climate crisis.

> My role transcends simply advocating to cut CO2. It's about promoting a nuanced debate and acknowledging that other solutions may be "much cheaper and more effective." I strive to help everyone "do it slightly less wrong," navigating the complexities without becoming demonized or mired in dogma.

Human emissions

> The wonder of our planet Earth, from the majestic Colorado River to the vast Arctic Ocean, showcases the beauty and complexity of our world - a realm filled with "mind-boggling" experiences that awaken a deep sense of awe.

> While humans have the capacity for great intelligence and technological advancement, we also grapple with ethical responsibility and our impact on Earth. The pivotal question remains: are we stewards helping the planet flourish or presenting challenges that need reflection and action?

> Recognizing the progress in human development, including increased life expectancy, literacy rates, and poverty reduction, highlights the potential for positive change. Amidst these advancements, the importance of addressing environmental concerns, poverty alleviation, and increasing global awareness through connectedness emerges as key priorities for a sustainable future.

Worst-case climate change scenario

> The narrative around climate change often amplifies worst-case scenarios, but it’s essential to understand that the actual mechanisms of extinction or collapse are complex and require extreme parameter choices. “What is the mechanism by which the human species becomes extinct because of climate change? I’m not sure I would want to be able to argue that,” reveals the nuance that these claims aren’t always grounded in clear pathways.

> The most significant impacts of climate change may not stem from sea level rise itself but rather the cascading effects, such as migration patterns and subsequent human conflicts. The “big negative impact” arises from how we respond to environmental changes, highlighting the interconnectedness of infrastructure, economy, and human behavior.

> Historically, humanity has demonstrated remarkable adaptability, whether in response to climate challenges or other crises. “We’re a very inventive species,” and while we might make costly mistakes along the way, there’s confidence that we can develop solutions, just as Chicago once raised itself to combat its urban issues. This resilience is key to addressing the multifaceted nature of climate change.

Hurricanes

> The relationship between climate change and disasters often gets oversimplified; while hurricane intensity may increase with warmer waters, the actual frequency of hurricanes isn't necessarily rising — "there's still... 90 or so hurricanes a year." It’s vital to understand that the increase in visibility and media coverage doesn't equate to an increase in events, as evidenced by recent years where hurricane counts have declined.

> Building vulnerability, not merely the storms themselves, drives disaster outcomes. As I pointed out, "a lot of the human suffering that has to do with storms is about where and how you build." Communities are increasingly situated in high-risk zones, escalating risks that aren’t just caused by climate change but also by poor planning and construction practices, particularly for the most vulnerable populations.

> The narrative on climate change should shift from alarmist "everything is doomed" perspectives to a more nuanced understanding that acknowledges human adaptability and resilience. As I emphasized, "climate change... means we're going to get better slightly slower," suggesting that our actions — or lack thereof — in terms of where we live and how we prepare are just as critical, if not more so, in determining outcomes moving forward.

Climate change vs Global warming

> The terminology around climate change has evolved over the years, reflecting both scientific focus and political spin. Terms like "global warming" and "climate change" are often used interchangeably; however, media outlets now emphasize phrases like "climate crisis" and "climate emergency" to intensify the public perception and sense of urgency. While these strong terms aim to raise awareness, they can also obscure the nuanced differences and potentially amplify unwarranted fear.

> It's critical to balance urgent climate action with practical vulnerability measures. The intense rhetoric of a "climate catastrophe" leads to extreme reactions and unrealistic timelines, which hinder productive dialogue on effective interventions. Focusing on immediate, actionable steps like reducing vulnerabilities can yield tangible benefits, whereas solely fixating on reducing carbon dioxide emissions could overshadow practical solutions and create a polarized narrative of good versus evil, particularly targeting fossil fuel companies.

Climate alarmism

> The interpretation of climate data, especially the IPCC reports, gets distorted by the media and political narratives. Most people don't delve into the 4,000 pages of research; they catch the sensational snippets that skew the real message, leading to confusion and alarmism, often preferring the scarier scenarios because they're more engaging.

> The narrative that climate change is the primary cause of various disasters oversimplifies complex issues. Many leaders latch onto the CO2 blame game to shift responsibility away from local governance and infrastructure failures. This scapegoating ignores other vital factors at play, such as historical injustices or policy failures.

> Spending trillions on climate policies often yields minimal benefits, and those financial resources could be better utilized in other areas that would produce more significant impacts on human welfare, like healthcare or education. The emphasis should shift toward holistic investments in energy solutions that not only address climate but also enhance productivity and societal well-being.

Economic models

> The overwhelming financial support for fossil fuel subsidies is not only wasteful but also disproportionately benefits the wealthy, as "poor people don't have a car," while the rich enjoy cheap fuel, perpetuating an unjust system that needs to be dismantled.

> Cost-benefit analyses of climate policies reveal that "virtually no model shows the transition to renewable energy is free," indicating that while change is necessary, it comes with significant economic costs that demand honest reckoning and transparency.

> The climate debate is not just about numbers and models; it’s crucial to build trustworthy systems and institutions that can foster effective climate action. As I reflect, “the hope lies in collaboration and creating models that include voices from diverse communities,” such as small entrepreneurs leveraging innovative solutions.

> Essential improvements in areas like child nutrition and education present incredible opportunities, offering "forty-five dollars worth of good" for every dollar spent, highlighting the importance of prioritizing solutions that address immediate human needs alongside long-term climate goals.

Climate change policies

> Investing in energy innovation, such as fourth-generation nuclear technology, holds the potential to significantly impact climate change by making clean energy cheaper and more accessible globally.

> Historically, solving complex global issues like pollution has been achieved through innovation rather than solely relying on behavioral changes or regulations, as seen in the case of the catalytic converter in addressing air pollution in Los Angeles.

> Shifting from a top-down approach to a more distributed strategy in addressing climate change is crucial, emphasizing the need for individual actions, technological advancements, and incentivizing innovation to drive meaningful progress towards a sustainable energy future.

Nuclear energy

> Nuclear energy has been suffering from a historical alarmism that has overshadowed its potential as a viable solution to climate change. "The traditional environmental movement still won't go there," and that resistance persists even among those who should recognize nuclear's significance in reducing carbon emissions.

> Additionally, while there are valid concerns about new nuclear plants being expensive, existing power plants offer a powerful advantage. "They're basically cheap or almost free CO2 base load power," and with escalating natural gas use due to shutdowns of facilities like Indian Point, the conversation should pivot to appreciating and optimizing current nuclear infrastructure rather than dismissing it entirely.

Alex Epstein

> Fossil fuels are the backbone of our society, supplying 80% of our energy and underpinning everything from low fertilizer prices to air conditioning; it’s crucial to acknowledge that “everything we take for granted... exists because we had this bounty that we dug out of the ground or pumped out of the ground.”

> Moreover, the narrative that we can forcefully transition away from fossil fuels is misguided; “to say that we're going to make fossil fuels expensive way before we have the solution is just terrible,” as it could leave many, especially in poorer nations, struggling to sustain their livelihoods.

Public opinion on climate change

> Climate change has become a deeply polarized issue, with stark divides between Republicans and Democrats; "if you call it climate ... the polarization goes away." This suggests the importance of reframing conversations around energy innovation and collaboration rather than tapping into the contentious climate label.

> Understanding beliefs about climate change isn't just about scientific literacy, but rather about the cultural context from which people derive their views. It's a complex interplay of "what you believe emerges based on culture" and the implications of such beliefs on policy acceptance.

> Cooperation can flourish when we focus on shared goals rather than differences; "you can disagree but still do a thing." It’s essential to foster dialogue that seeks to unite people in their desire for a better future while respecting their individual beliefs and fears surrounding regulation and governmental control.

US presidents

> The perception that presidents significantly shape climate policy is misleading; while there have been some innovations and frameworks introduced, such as Obama's focus on sectoral approaches and Bush's inadvertent push for fracking, "you couldn't ever measure enough" to see a clear impact on climate trajectory within measurable time frames.

> True progress hinges on innovation and addressing vulnerabilities rather than merely engaging in "virtue signaling." It’s evident that effective solutions come from understanding local needs, as demonstrated in Bangladesh where improved disaster preparedness has drastically reduced fatalities from storms, proving that "when you get flooded... you can still have your income and your future."

Advice for young people

> - The key advice to young people is to shift away from catastrophism in the climate conversation. Recognize the improvements in the world and focus on finding ways to contribute positively to society, whether through developing innovative solutions like fourth-generation nuclear energy or addressing pressing global issues like tuberculosis.

> - Embrace adaptability and media literacy in today's rapidly changing world. Understand the dynamics of different information mediums, cultivate the ability to communicate effectively about your work, and engage with diverse disciplines for impactful collaborations.

> - Balance a sense of urgency with patience when addressing challenges like climate change. Act with urgency to address pressing issues while understanding that meaningful change takes time. Stay informed, adapt to evolving communication technologies, and strive for usefulness in scientific endeavors to make a tangible difference in the world.

Meaning of life

> Life, in essence, is about "making the world a better place," and though it may sound cliché, it truly captures the core of our existence. It’s about supporting those around us, addressing significant issues like climate change, and using our resources wisely amidst countless challenges.

> The journey requires a nuanced understanding of what we can and cannot change, embodying the wisdom of knowing that "the human journey will have some" difficulties, yet it’s still possible to create a "less bad" tomorrow through meaningful action and collaboration.
