Climate change has long forced International Relations scholars to think across borders. Thomas Hale’s Long Problems argues that it should also force them to think across time. To that end, the book engages several key debates, including classical IR theories of collective action and institutional design, work on Earth System Governance, and recent scholarship on transnational and experimentalist governance. Hale’s central claim is that the most consequential political challenges of the present are not simply transboundary but intertemporal. They unfold over timescales much longer than those of elections, policy cycles, and even the analytical horizons of much contemporary political science. The book’s contribution is to offer a framework for understanding why such “long problems” are hard to govern—and what institutional reforms might make governance across time feasible. It is an ambitious and often illuminating argument, one that ends with a clear sense of what reforms are needed. At the same time, the book’s empirical stocktaking could have been more systematic, and the extent to which its framework travels beyond climate change remains open to question.
The book begins by asking readers to take an often-neglected dimension of political problems seriously—their length. Hale defines “long problems” as those “whose causes and effects span more than one human generation” (p. 3). Climate change is the paradigmatic case and receives by far the greatest attention in the book. Still, Hale points to other long problems and draws on examples from fields ranging from demographic change and war to artificial intelligence and global pandemics. His broader claim is that long problems are difficult to govern because they generate three political dilemmas: the early action paradox, shadow interests, and institutional lag. One of the book’s strengths is that Hale introduces these dilemmas in a meticulous yet accessible way while also linking them to concrete governance solutions designed to mitigate them.
The first dilemma is the early action paradox: in the case of long problems, meaningful action must occur well before effects are felt, yet that is precisely when uncertainty is high, salience is low, and obstruction from groups benefiting from the status quo is easiest. Hale distinguishes three kinds of solutions. First, information can raise awareness of the future implications of near-term decisions through tools such as independent impact assessments. Hale is clear that information alone is rarely sufficient, but it matters when it raises salience and aligns actors supporting long-term goals. Second, experimentalist governance can address uncertainty through iterative learning and diffusion, especially where a diverse set of actors is able to develop and compare solutions. Third, catalytic strategies can shift incentives by creating self-reinforcing processes—through new technologies, norms, or constituencies—that make further action easier.
The second dilemma of long problems is what Hale terms shadow interests: those most affected by long problems are not yet born and cannot organize, vote, or otherwise exercise agency in the present. Hale again offers three broad responses. One is to create institutions mandated to represent future interests, such as commissioners or committees that give future generations a “voice” in decision-making. A second, and stronger, strategy is trusteeship: delegating real authority to institutions with long-term mandates insulated from short-term pressures, such as courts or environmental agencies. A third strategy is to shift the time horizons of actors themselves through rule changes. Here, Hale points to rule changes that reward longer-term behavior, but also to capacity-building, education, deliberation, and activism as ways of extending the temporal horizons of politics.
The third and final dilemma is institutional lag: institutions created to address the early stages of a problem often become a poor fit as that problem evolves over time. Hale treats institutional lag as a problem of balancing endurance and adaptability. The first response is to lock in long-term goals—formally or informally—and establish yardsticks against which progress can be assessed. The second is reflexive governance in the form of institutionalized review, revision, and updating procedures that allow policies to adapt as conditions change. The third is the use of triggers and reserves, that is, mechanisms that either activate automatically when circumstances shift or preserve resources for later use. These devices matter because long problems require institutions that can endure and adapt. Yet Hale is equally attentive to their limits: goals can become too vague or conflict with other priorities, reflexive governance can weaken durability if everything remains too malleable, and triggers or reserves work only when shielded from short-term political pressures.
This is an elegant framework. One of the book’s most compelling moves comes in its conclusion, which brings the earlier parts together and translates them into an institutional agenda for governing across time. Hale suggests that as the impacts of climate change intensify, politics may become more reactive and short-term, not less. Yet he also argues that the present creates a window of opportunity in which climate change is severe enough to generate urgency, but not yet so overwhelming as to foreclose long-term governance reforms. That tension gives the book much of its force. For all its concern with long-term problems, the book ultimately ends by insisting on the urgency of action today.
At the same time, the book seems open to two criticisms. First, Hale is explicit that he is not undertaking original empirical work in this book, opting instead for “a wide range of illustrative examples from around the world” rather than “a set of cases” (p. 15). Yet a slightly more systematic analysis may have added another interesting layer to the book. Hale includes examples from many countries, but the United States and China recur regularly—and rightly so, given their contributions to global emissions. By contrast, the European Union features only marginally, even though it probably comes closest to the kind of long-term institutional governance Hale has in mind. A more systematic comparison of the United States, China, and the European Union might have further strengthened the book’s empirical appeal. Second, there remains a tension between the book’s general language of “long problems” and its sustained focus on climate change. Other problems also extend far into the future, but readers may still wonder how far the framework and proposed solutions travel across problems characterized by different actor constellations, power structures, and normative stakes. These are not fatal weaknesses. But they do suggest that the book is best read as an ambitious opening intervention in a broader conversation rather than as a settled account of how governing across time works.
Even so, Long Problems is analytically incisive, substantively important, and thought-provoking. It makes a persuasive case that political science has not yet sufficiently reckoned with long problems and offers a compelling framework for thinking about how they might be governed. Hale gives a pressing political challenge a clear conceptual form while also making a forceful case for reforms that may still help avert the worst of climate change. Scholars of International Relations, climate governance, and political science more broadly will find much to learn from this book—not least because it insists that the window for meaningful action is narrowing. In that sense, Long Problems is not only a work of analysis, but a call to action before that window closes.
