For centuries, humanity built its development on a seemingly unshakable premise: that the past was the best tool for anticipating the future. Farmers sowed their crops according to calendars passed down through generations; engineers designed bridges, roads, dams, and drainage systems using historical records of rainfall and river flows; cities planned their expansion around areas that, according to experience, had never flooded. The underlying assumption was that nature followed cycles, and that this cyclical behavior of natural phenomena made planning possible.
Today, that logic is beginning to break down—not because science has ceased to understand the climate, but because the climate system itself is changing. Recent research, including studies conducted by scientists at the Massachusetts Institute of Technology (MIT), warns that global warming is altering the conditions on which traditional forecasting models rely. The problem is not simply that extreme weather events are becoming more frequent, but that many of them are occurring outside the historical patterns that for decades served as the basis for designing infrastructure, planning agricultural production, and assessing risk.
The atmosphere is inherently a chaotic system, where small variations can produce entirely different outcomes. As global temperatures rise, the atmosphere stores more energy and more water vapor, intensifying the interaction between oceans, air currents, and pressure systems. As a result, the limits of predictability begin to shrink. A study by Stanford University found that, under higher warming scenarios, the ability to produce reliable weather forecasts could decline even over timescales of just a few days.
Recent events appear to confirm this trend. In March 2025, for example, Bahía Blanca, Argentina, received nearly 300 millimeters of rainfall in just six hours. The resulting floods claimed lives, caused billions in losses, and brought the city to a complete standstill. A subsequent analysis by World Weather Attribution concluded that the conditions behind the event were intensified by global warming: an intense heatwave, an atmosphere carrying more moisture, and a cold front that triggered unprecedented rainfall for the region. Most concerning was the researchers’ conclusion: historical records were no longer sufficient to explain the magnitude of the event. A similar situation occurred in Valencia, Spain, where the 2024 floods demonstrated that even countries with advanced monitoring systems can be overwhelmed when their infrastructure was designed for a climate that no longer exists. The rainfall was extraordinary, but it also exposed the fact that cities continue to rely on risk maps based on historical statistics.
The World Meteorological Organization warns that temperatures over the next five years are expected to remain near or above historical highs, increasing risks to economies, food security, water availability, and critical infrastructure. We are no longer dealing solely with an environmental problem; we are confronting a development challenge. The economic consequences are enormous. The World Bank, the Intergovernmental Panel on Climate Change (IPCC), and numerous international organizations agree that the greatest costs of climate change will not stem only from the direct damage caused by storms, floods, or droughts, but also from the growing uncertainty these phenomena create for investment, agricultural production, energy systems, insurance markets, and public finances.
When the climate no longer behaves as it once did, many decisions built upon historical experience also cease to function effectively. Latin America faces particular vulnerabilities. Nearly half of its electricity generation depends on water resources, millions of people rely on agriculture for their livelihoods, much of its transportation infrastructure crosses mountainous regions prone to landslides, and many coastal cities face growing risks from extreme rainfall and rising sea levels. At the same time, resources for adaptation remain limited. Faced with this reality, some countries have begun to embrace a new paradigm. The Netherlands no longer seeks to contain all water behind dikes; instead, it designs spaces that allow rivers to expand when necessary. Japan incorporates climate resilience criteria into every new public infrastructure project. Singapore combines artificial intelligence, real-time sensors, and nature-based solutions to manage urban flooding. The question is no longer how to eliminate risk entirely, but rather how to keep society functioning when that risk materializes.
This shift in perspective should also reach Latin America. For decades, we invested enormous resources in improving our ability to predict the future. Yet the twenty-first century demands that we strengthen another equally important capability—one that, while not new, defines a new model of regional policymaking centered on adaptation. Cities capable of absorbing extraordinary rainfall; more resilient power grids; agricultural systems supported by probabilistic scenarios; infrastructure designed for variable conditions rather than historical averages alone; and restored ecosystems that serve as natural barriers against floods and droughts. Perhaps the most important lesson of contemporary climate science is not that the climate has become unpredictable, but that the past is no longer sufficient to describe the future. Understanding that distinction may well determine the course of development over the coming decades.
The societies that thrive will not necessarily be those that can anticipate every storm, every drought, or every wildfire. They will be those that recognize uncertainty as an inherent feature of the new climate and understand that preparing for it is not merely an expense, but one of the smartest investments a country can make. The time has come not only for industry and policymakers to confront this new challenge, but also for academia to train professionals with strong research capabilities, reinforcing the understanding that a new future is taking shape—one defined by a less predictable climate and by infrastructure that must be redesigned according to this new paradigm.
