The Earth's interior heat represents an often overlooked dimension of climate change. While most discussions focus on atmospheric warming, changes in our planet's geothermal systems are equally significant. Recent studies indicate that rising global temperatures affect underground heat patterns, potentially altering subsurface water systems and geological stability. These disruptions may intensify volcanic activity and earthquakes in certain regions. Scientists are monitoring these changes carefully to understand the long-term impacts on both natural environments and human settlements. Geothermal energy offers a sustainable solution amid climate concerns. This renewable resource harnesses heat from within the Earth to generate electricity and provide heating without producing greenhouse gases. Countries like Iceland and New Zealand have successfully implemented geothermal power plants, demonstrating their feasibility. The technology has matured considerably in recent decades, making it more accessible and cost-effective. Despite these advantages, geothermal energy remains underutilized globally, accounting for less than 1% of worldwide electricity production.
