Chapter 1: The Science of Climate Change

As I embarked on my academic journey at the University of Minnesota in 1980, I encountered my first scientific paper on climate change, published in 1979. This article was part of a literature review for my environmental geography course, drawing from studies predominantly released during the 1970s. Back then, scientists referred to the phenomenon as the "greenhouse effect," which eventually evolved into the term "climate change."

Fast forward to today, and the statistics regarding our climate have only worsened. For instance, CO2 emissions have surged by over 90% since 1970. A recent report from the Intergovernmental Panel on Climate Change (IPCC) states: "Since 1970 the global average temperature has been rising at a rate of 1.7°C per century, contrasting with a long-term decline over the past 7,000 years at a baseline rate of 0.01°C per century." According to the EPA, the repercussions of these changes are evident: "The planet's oceans and glaciers have also experienced changes — oceans are warming and becoming more acidic, ice caps are melting, and sea levels are rising." Additionally, we witness well-documented instances of floods, droughts, and extreme heat waves, all linked to climate change.

Despite the clarity of scientific evidence, the situation continues to deteriorate. This raises the question: why, after fifty years of robust data and advocacy (including Al Gore's Inconvenient Truth campaign in 2006), are we still facing escalating environmental crises?

"Facts tell, stories sell." This marketing adage captures the essence of the climate movement over the past fifty years. While numerous academic studies, think tank reports, and advocacy efforts have inundated the public with facts, they have not translated into widespread behavioral changes. Alarmingly, 25% of Americans—approximately 83 million individuals—either doubt or outright reject the scientific consensus on climate change.

Chapter 2: Understanding Public Perception

This skepticism has serious implications. Those who assert that "the science indicates that if we all did X, we could reduce carbon emissions by Y" must adjust their expectations by at least 25%, as a significant portion of the population remains unconvinced. Furthermore, many others may reject specific actions for various reasons, resulting in an even larger number of individuals unwilling to contribute to emissions reduction efforts.

Thus, it becomes evident that even if scientific recommendations suggest effective strategies for carbon reduction, human behavior does not align with those proposals. With a substantial segment of the population unwilling to adapt, the anticipated benefits from these strategies are unlikely to materialize.

While scientific data remains crucial for informing us, it is no longer sufficient as a persuasive tool. After decades of evidence, emissions continue to climb, consumption patterns worsen, and global temperatures rise. So what alternatives do we have if presenting scientific facts does not yield the desired action?

Chapter 3: Expanding Motivations for Change

We can explore two primary paths: enhancing motivations for desired consumer behaviors or restructuring the system to eliminate consumer choices.

Changing Motivations

By leveraging scientific insights, we can identify the behaviors we wish to promote within society. For example, we understand that solar energy is emission-free, and it would be beneficial for households to install solar panels. While some individuals motivated by climate science have adopted solar technology, many remain hesitant for various reasons. About 25% of the population is skeptical about climate science, while others may lack the financial resources to invest in solar installations. Additionally, concerns about potential roof repairs and the perceived ineffectiveness of individual actions can deter adoption.

An autocratic regime might mandate solar panel installations, as seen in China, but such measures are improbable in the U.S. Instead, we should consider addressing the concerns that prevent people from adopting solar technology. For instance, rather than offering tax credits—which often benefit only higher-income individuals—direct subsidies could be provided. Financing options could ensure that a household's electricity costs remain lower than expected. Moreover, government insurance could be introduced to cover roof repairs, making solar installations a more appealing option. By transforming the perception of solar adoption from a risky investment to a financially advantageous decision, we can motivate broader participation regardless of beliefs about climate science.

Chapter 4: Eliminating Consumer Choices

The second approach involves removing the option for environmentally harmful choices. Currently, individuals can select between traditional internal combustion engine (ICE) vehicles and electric vehicles (EVs), or choose between fossil fuel-powered electricity and renewable sources. However, the same 25% of the population that doubts climate science is unlikely to opt for climate-friendly alternatives.

Historically, consumers faced no alternatives; ICE vehicles and fossil fuel electricity were the only choices available. Today, while it is positive that we have options, the goal should be to move toward a system where climate-friendly options are the exclusive choices.

What if there were no ICE vehicles available, and the only cars on the market were EVs? What if all electricity came exclusively from renewable sources? This transformation is already underway. Major automakers like Audi plan to offer only EVs by 2026, while Honda aims for a complete transition by 2030. As the automotive industry moves away from polluting options, consumers may find themselves without the choice of purchasing gas-powered vehicles.

While the transition to renewable electricity generation is still lagging, it is essential for the mix of energy sources to evolve. As renewables make up a larger share of electricity generation, consumers will increasingly find themselves without the option to purchase high-carbon electricity. The end result will be a scenario where participation in climate solutions becomes universal, not because of coercion, but simply due to the absence of alternative choices.

Chapter 5: A Comprehensive Strategy

While science plays an important role in diagnosing our environmental challenges and identifying effective solutions, motivating people to adopt these solutions requires a focus on marketing and human behavior. This includes restructuring incentives, integrating solutions into existing systems, and rebranding current facts to make them more accessible. Ultimately, effective climate action hinges on our ability to align human motivations with environmental goals.
