10 Climate Change: Environmental Stressors and Their Geopolitical Implications

Climate change is no longer just an environmental issue—it is a profound geopolitical challenge that is reshaping borders, forcing mass migrations, and destabilizing regions. As global temperatures rise, sea levels increase, and extreme weather events become more frequent, the implications for national security, international relations, and global governance are increasingly dire. This chapter focuses on the intersection of environmental data and geopolitics, exploring how climate change is becoming a central factor in shaping global power dynamics. Using data science, we can model climate risks, track environmental changes, and predict regions where resource scarcity, migration, and border conflicts may escalate into geopolitical crises.

One of the most direct consequences of climate change is the impact on national borders and territorial disputes. Rising sea levels threaten to submerge low-lying island nations and coastal regions, while melting ice in the Arctic is opening new trade routes and sparking competition for untapped natural resources (Keil, 2014). Similarly, the increasing frequency of extreme weather events, such as hurricanes, floods, and droughts, is leading to widespread displacement, putting pressure on neighboring countries and triggering migration crises. Data science tools, such as predictive modeling and geospatial analysis, are essential in mapping these risks and identifying hotspots of future conflict.

For example, Bangladesh is one of the countries most vulnerable to rising sea levels, with predictions suggesting that large portions of the country could be underwater by 2050, displacing millions of people (Islam & Winkel, 2017). This potential mass migration could lead to tensions with neighboring India, which is already grappling with border security issues. Meanwhile, the melting of glaciers in the Himalayas is affecting water supplies for millions of people across India, China, and Pakistan, raising concerns about future water conflicts in this highly militarized region (Pomeranz, 2019).

Data science models can project the scale and timing of these environmental stressors, allowing policymakers to develop strategies for conflict prevention and disaster preparedness. Climate migration—the movement of people due to environmental changes—represents one of the most significant geopolitical challenges of the coming decades. By integrating climate models with migration data, researchers can predict migration flows and assess the social, economic, and political impacts on both sending and receiving countries (Black et al., 2011). As resource scarcity and displacement become more pronounced, nations must develop cooperative frameworks to manage these challenges, or risk escalating tensions.

10.1 Energy Transition: The Geopolitics of Renewable Energy and Fossil Fuels

The global energy landscape is undergoing a dramatic transformation as the world shifts from fossil fuels to renewable energy. This transition is reshaping geopolitical alliances, altering the balance of power among energy-producing and energy-consuming nations, and creating new forms of competition for technological and resource dominance. Data on energy consumption, production, and technological advancements is crucial for understanding how countries are positioning themselves for the future of energy and what the geopolitical implications of this shift will be.

For much of the 20th and early 21st centuries, fossil fuels—particularly oil, natural gas, and coal—have been the foundation of global energy systems and geopolitical strategy. Nations with abundant fossil fuel reserves, such as Russia, Saudi Arabia, and the United States, have wielded significant influence over the global economy by controlling access to these critical resources. However, as the world moves toward decarbonization and the adoption of renewable energy technologies, the geopolitical map is being redrawn.

Countries that were previously dependent on fossil fuel imports are now investing heavily in solar, wind, hydropower, and nuclear energy to reduce their reliance on foreign energy supplies. For example, Germany’s Energiewende (energy transition) policy aims to phase out nuclear and coal power while ramping up investments in wind and solar energy. Similarly, China has become a global leader in solar panel production and electric vehicle (EV) technologies, positioning itself as a dominant player in the renewable energy market (Zhang et al., 2016).

The shift to renewable energy also raises important questions about the control of critical minerals. The production of wind turbines, solar panels, and EV batteries depends on materials like lithium, cobalt, and rare earth elements, which are concentrated in a small number of countries, including China, Chile, and the Democratic Republic of Congo (Nassar et al., 2020). This creates new geopolitical dependencies, as nations that dominate the extraction and processing of these minerals will wield significant influence over the future energy economy. Data science tools, such as supply chain analysis and market simulations, help track the global flow of these critical materials and predict potential supply bottlenecks.

The energy transition is also reshaping global trade routes and alliances. As countries reduce their dependence on oil and gas, traditional energy exporters like Saudi Arabia and Russia are facing significant economic and geopolitical challenges. To remain relevant, many of these nations are diversifying their energy portfolios by investing in renewables and hydrogen technologies (IRENA, 2020). The geopolitics of hydrogen, in particular, is emerging as a key area of competition, with countries like Japan and Germany positioning themselves as leaders in hydrogen technology, while oil-exporting nations are exploring how to use their existing infrastructure to produce and export green hydrogen.

In addition to resource competition, the energy transition has sparked technological competition among nations. Countries that can innovate in renewable energy technologies and energy storage will have a strategic advantage in the global energy market. Data science techniques like predictive analytics and technology adoption modeling allow researchers to track the diffusion of renewable technologies and forecast which countries are likely to emerge as leaders in the energy transition.

The shift from fossil fuels to renewable energy will also have profound implications for global security. As nations move away from oil and gas, petrostates—countries whose economies are heavily reliant on fossil fuel exports—may face significant instability if they fail to diversify their economies. Venezuela, Nigeria, and Saudi Arabia are examples of countries that are vulnerable to the economic shocks caused by declining fossil fuel demand. Data-driven models can assess the risk of political unrest and economic collapse in these nations, providing early warnings to policymakers and international organizations.

Meanwhile, countries that are well-positioned to lead the energy transition, such as China, Germany, and Denmark, will gain geopolitical leverage by exporting renewable energy technologies and dominating global supply chains for critical materials. As the world moves toward a more decentralized energy system, with renewables being produced and consumed locally, the traditional geopolitical power of fossil fuel exporters will decline, while nations with the technological capacity to drive the energy transition will rise.

10.2 Conclusion

The twin challenges of climate change and the energy transition are reshaping the global geopolitical landscape in profound ways. Rising sea levels, extreme weather events, and resource scarcity are creating new sources of conflict, while the shift to renewable energy is altering traditional power dynamics in the energy market. Using data science tools like predictive modeling, geospatial analysis, and supply chain tracking, we can better understand how these environmental and energy trends are influencing international relations and geopolitical stability.

The countries that can adapt to these changes—by managing the risks of climate change and seizing the opportunities of the renewable energy transition—will be the ones that shape the future of global geopolitics. Whether through cooperation on climate mitigation efforts or competition for control of renewable energy technologies, the intersection of environmental stressors and energy dynamics will define the geopolitical battles of the 21st century.
