“To think that we can draw some useful analogies from history dramatically underestimates the novelty and scale of the climate challenge.”[2]

“In the contest between geopolitics and sustainable climate policies, the former takes precedence.”[3]

Starting in the early 1980s, I have spent my entire professional life studying climate change, as well as teaching, writing and speaking about it in universities, conferences, and public forums around the world—in 43 countries at the latest count. With such a professional and personal investment in the idea of climate change, it is not surprising that for a long period I uncritically absorbed the notion that climate change represented the pre-eminent challenge facing humanity in the twenty-first century.

Since first immersing myself in the topic in the 1980s, and subsequently being part of the scientific and public story of climate change in the 1990s and 2000s[4], I was easily convinced that the growing human influence on the world’s climate would be a reality that all nations would increasingly need to confront, a reality to which their interests would necessarily be subservient and that would be decisive for shaping their development pathways. For more than half of these 40 or so years, it seemed to me self-evident that relations between nations would forcibly be re-shaped by the exigencies of a changing climate.

But now, in the mid-2020s, I can see that I got this the wrong way round. And I can also see why this was so. Rather than geopolitics having to bend to the realities of a changing climate, the opposite has happened. //

Now, 30 years later, it is the geopolitical truth that power and interests win out. Climate is not the only thing that is changing through our lifetimes, and perhaps not the most important thing. Technology, cultural values, the centres of political, economic and military power have all changed remarkably since I first started studying climate change 40 years ago; and the rules, cohesion and effectiveness of the international order that I assumed were eternal are being seriously called into question. I now see the need for a deeper reading of political realism and power, that goes beyond seeing science as a coercive force that trumps geopolitics, beyond appeals to a superficial cosmopolitanism. To use the language of Jason Maloy at Louisiana University, climate change is neither an emergency or a crisis; it is a political epic, “a process of collective human effort that features gradual progression through time, obscure problem origins, and anticlimactic outcomes.”[25]

The best that we can say is that the world will continue slowly to decarbonize its energy system and, at the same time, the Earth will continue slowly to warm. And societies will continue to adapt to evolving climate hazards in new ways, as they have always done, with winners and losers along the way.
