For the past 20 years, the United States has considered climate change not only as an environmental issue but also as a matter of national security. In 2007, experts first suggested incorporating the effects of climate change into the country's national security, defense, and military strategies. This approach aimed to make military operations more resilient, efficient, and environmentally aware, while also improving the ability to detect and respond to climate-related threats more effectively. In a video, Sherri Goodman, Vice Chair of the United States' International Security Advisory Board, outlines how the U.S. military has adapted to the challenges posed by climate change and has worked to increase the resilience of its armed forces. Goodman highlights the growing recognition that climate change can impact military readiness, operations, and infrastructure. The U.S. military has taken several steps to address climate and defense issues. These include assessing the risks that climate change poses to military bases and operations, investing in renewable energy sources to reduce dependence on fossil fuels, and developing strategies to protect military assets from extreme weather events. These efforts are part of a broader initiative to ensure that the military remains prepared for the challenges of a changing climate. Energy independence has become both a strategic and environmental priority for the military. By reducing reliance on foreign oil and increasing the use of renewable energy sources, the military aims to enhance its operational flexibility and reduce its environmental footprint. This shift is also seen as a way to improve energy security and reduce vulnerabilities associated with traditional energy supplies. The Arctic region is emerging as a key area of geopolitical interest due to the effects of climate change. As Arctic ice melts, new shipping routes and access to natural resources are opening up, leading to increased competition among nations. This has raised concerns about potential conflicts and the need for stronger international cooperation to manage the region's resources and ensure stability. The Arctic thus serves as a real-world example of how climate change can influence global security dynamics. The article Climate change in US military doctrine first appeared on IRIS.
