"The role of radiocommunications in addressing climate change cannot be overstated. From providing critical information on weather patterns and natural disasters to facilitating coordination across global networks for disaster response, these technologies offer unmatched capabilities. As extreme weather events become more frequent and severe, radiocommunication systems are vital in bridging gaps between remote areas and central emergency operation centres, ensuring that no one is left behind in the battle against climate change. Additionally, the ability to monitor environmental variables through various sensors and satellite networks is essential for understanding the full extent of climate change. By integrating advanced communication systems, we can strengthen our ability to adapt to these changes—improving early warning systems, optimizing resource management, and fostering collaboration across borders and sectors. This brochure highlights the critical role of radiocommunications in tackling the global challenge of climate change. Through enhanced connectivity, data sharing, and technological innovation, we can empower communities, governments, and organizations to both mitigate and adapt to the ever-changing climate crisis. Let us harness the power of technology to create a more resilient, connected, and sustainable future for all." (Foreword)
