In the 1950s and 1960s, as the world grappled with the dawn of the fossil fuel era, governments were already aware of the risks of global warming. This revelation, detailed in the Center for International Environmental Law's (CIEL) recent report, 'What Countries Knew', is both eye-opening and deeply concerning. The report highlights how major industrialized nations, including the United States, Australia, Canada, Germany, Italy, Norway, the UK, and the former Soviet Union, were well-informed about the dangers of burning fossil fuels as early as the 1950s. This knowledge, however, did not seem to deter these countries from their fossil fuel-driven growth trajectory. Personally, I find this historical context particularly fascinating and deeply troubling. What makes this story so compelling is the stark contrast between the awareness of the risks and the actions taken (or not taken) to mitigate them. The report, led by senior researcher Lindsay Fenlock, reveals that climate scientists were presenting their findings to governments as early as the International Geophysical Year in 1957. This period saw about 70 countries collaborate to study Earth as an interconnected system, and it was during this time that American scientists Roger Revelle and Hans Suess characterized the rising CO2 levels as an unprecedented and irreversible 'large-scale geophysical experiment'. The warnings grew more urgent in the 1960s, as governments and economies of industrialized and industrializing countries doubled down on fossil-fueled growth. In 1965, President Lyndon Johnson was warned that rising CO2 levels could cause 'marked changes' in climate. Yet, despite this knowledge, the U.S. continued to subsidize oil production, and other countries, like Norway and Italy, encouraged their state-owned oil companies to expand. This raises a deeper question: If these governments were aware of the risks, why did they not take more proactive measures to mitigate them? From my perspective, the answer lies in the complex interplay of economic, political, and social factors. The fossil fuel industry, with its powerful lobbyists and deep-pocketed interests, has long been a major player in shaping government policies. The report also highlights the irony of the situation. While governments were aware of the risks, they were simultaneously celebrating the prosperity brought by fossil fuels. In Germany, for instance, newsreels celebrated record coal hauls with images of miners grinning through sooty faces. In the U.S., federally subsidized oil production meant prosperity and the freedom to 'Put a Tiger in Your Tank'. This raises a crucial point: What makes this situation even more concerning is the fact that the knowledge was not confined to scientific circles. It was disseminated to the broader public, and yet, the response was largely inaction. The report's legal significance is also noteworthy. It draws 'important connections' between the history of government knowledge and the legal obligations outlined in the ICJ's Advisory Opinion. Michael Burger, executive director of the Sabin Center for Climate Change Law at Columbia University, sees this as a 'warning shot' for those on the lookout for cases that may follow in the wake of the ICJ's opinion. The report, however, does not establish liability but provides crucial evidence that could help hold governments accountable for resulting damages and require them to act with greater urgency. The implications of this knowledge are far-reaching. Under a broad reading of international environmental legal principles, some countries could be held responsible for their share of climate damages caused by their emissions even before they understood the risks. But pinpointing when governments became aware of those risks establishes a clearer threshold for legal liability. From that point onward, governments had the opportunity to change course, and those that instead continued or expanded fossil fuel use bear greater responsibility for resulting harms and for helping affected communities now. In conclusion, the report 'What Countries Knew' is a powerful reminder of the historical knowledge of global warming risks and the inaction that followed. It raises important questions about the role of governments and the fossil fuel industry in shaping our climate future. As we move forward, it is crucial to learn from this history and take proactive measures to mitigate the risks of global warming. Personally, I believe that this report should serve as a wake-up call for governments and the fossil fuel industry to take responsibility for their actions and work towards a more sustainable future.
