Step outside, and the scenery of spring greets you. Yet, beneath this familiar facade lies a subtle shift, unnoticed by many. The accelerating rise in global average temperatures is blurring the distinct boundaries of the four seasons, leading to an increasing frequency of unpredictable climate changes. Against this backdrop, recent discussions on climate policy are evolving beyond mere environmental protection to address an economic imperative. While it's commonly assumed that scientific predictions will perfectly underpin climate change mitigation policies, this might be an overconfident assertion. Professor Charles Manski of Northwestern University, in his 2026 paper 'Credible Climate Planning Under Uncertainty: Beyond Incredible Certitude,' argued that climate change should not be approached solely as a scientific problem but as an economic insurance system. The phrase 'Beyond Incredible Certitude' in his paper's title penetrates to the core of the current climate policy debate. Many policymakers expect science to provide definitive answers, but climate science, in reality, still contains significant uncertainties. According to Professor Manski, while climate change is a common challenge for all nations, the impacts and response methods can vary depending on each country's economic structure and policy direction. He emphasizes that climate policy should be designed much like investing in insurance to reduce the costs of catastrophic events. This perspective offers significant value in designing existing climate change response strategies more practically and economically. The essence of insurance is converting uncertain future losses into certain present costs. Similarly, climate policy should be understood as investing now to prevent potential future catastrophes. The core of this approach is 'credible planning.' Professor Manski argues that climate policymakers should frankly acknowledge scientific uncertainties while designing policies to minimize worst-case scenarios and promote public welfare. This represents a middle-ground approach, avoiding the common pitfalls of the climate change debate: either waiting for 'perfect scientific certainty' or, conversely, 'completely ignoring science.' In the context of South Korea, the current industrial structure and energy consumption patterns are at a critical juncture for climate change response. South Korea's manufacturing-centric economy has a high proportion of energy-intensive industries, making carbon emission reduction a more complex challenge. The nation's overall energy supply relies significantly on fossil fuels, and while policies are being implemented to reduce this dependency, achieving targets remains challenging. As one of the major carbon emitters, South Korea is positioned to play a crucial role in the global response to climate change. However, as Professor Manski emphasized, science is not a panacea for all problems. His paper clearly states that scientific uncertainty remains one of the core challenges in addressing climate change, and policies for it should be designed around economic rationality rather than scientific certainty. Indeed, while climate science clearly predicts long-term temperature rise trends, uncertainties persist regarding specific regional impacts or the precise timing of tipping points. Some environmental policy experts also acknowledge the limitations of science and are striving to diversify approaches to climate change response. For instance, several countries that have set 2050 carbon neutrality targets are adopting adaptive and flexible policies, dealing with evolving environmental data throughout the process. This involves setting initial goals but adjusting the path based on new scientific evidence and technological advancements. Insurance Strategy: The Best Option in an Era of Uncertainty South Korea's climate policy also requires such creative and adaptive endeavors. Energy transition policies, which seek changes in electricity generation composition, inevitably entail the adoption of renewable energy and the restructuring of existing industrial frameworks. The recent expansion of solar and wind power offers a positive direction, but challenges remain in power storage technology and grid stability. The development of ESS (Energy Storage System) technology and the establishment of smart grids must proceed concurrently to address the intermittency issues of renewable energy. Experts assess that South Korea's unique geographical conditions and high urban density present both distinct constraints and opportunities for climate policy design. The limited land area restricts the construction of large-scale renewable energy facilities, yet high population density simultaneously provides favorable conditions for establishing public transport-centric low-carbon transportation systems. This implies that true solutions lie not in focusing on short-term goals but in harmoniously considering economic viability and environme
