Exploring the parallels between the early skepticism of germ theory and today’s climate change denial, this article reveals how actions, rather than beliefs, can drive solutions to global challenges.
Strange as it may seem, early germ theorists could shed light on today’s attitudes toward climate change. While researching for a book on the history of emerging infections, I found striking similarities between the 19th-century debates over microbes and the current discourse on global warming.
Both controversies highlight the difficulty of perceiving unseen threats. Just as 19th-century skeptics doubted the existence of “animalcules” until microscopes proved them real, many today struggle to grasp the larger patterns and long-term impacts of climate change without the aid of scientific data. Yet, acknowledging these invisible threats is crucial for human solutions.
Economic interests often muddy the waters. In the past, quarantines to prevent infections were resisted due to their impact on trade. Today, recommendations to reduce carbon emissions face pushback from industries reliant on fossil fuels. This resistance can be attributed to the threat posed to both livelihoods and profits, leading to divisions even within labor unions and the spread of misinformation by energy executives.
However, consensus on belief isn’t always necessary for progress. In the late 19th century, even surgeons skeptical of germ theory adopted antiseptic techniques pioneered by Joseph Lister because they saw improved patient outcomes. Lister himself noted that regardless of their reasons, the adoption of these practices was what mattered most.
This principle applies to climate change as well. Changing behaviors is more critical than changing beliefs. For instance, many evangelical Christians, through organizations like Green Faith and the Creation Care Task Force, promote environmental stewardship as a religious duty. While some of their core beliefs may conflict with scientific theories, their actions contribute to the broader goal of reducing fossil fuel dependence.
Economic incentives also play a significant role. A Pew survey revealed that a majority of Americans, including many Republicans, support renewable energy development. This support often stems from the economic benefits of renewable energy, as seen in red states leading in wind and solar energy production due to favorable returns and stable income sources for farmers.
Finding common ground is key. Just as the 19th-century consensus on disease prevention led to significant mortality declines, diverse groups today can unite around shared benefits to address climate change. While disagreements on the pace and extent of renewable energy adoption persist, the potential for collaborative solutions offers hope.
In conclusion, humanity’s ability to address climate change does not depend solely on universal belief in it. Historical parallels with germ theory demonstrate that practical actions driven by common interests can lead to significant progress, regardless of differing beliefs.
