Early Warning is a powerful tool for leveraging Humanity´s ability to think about and build the future. It provides a way to think about possible, alternative, and desired futures and scenarios. By doing so, it enables individuals, organizations, and nations to prevent, prepare for, respond, and recover from events and build a better future. In the coming decades, and possibly until the end of the 21st century, which is a time of transition of geopolitics and the environment, Humanity is likely to face significant challenges with a more complex, unstable, and uncertain Future. Exploring the capabilities of Early Warning for People, Places and Planet, is opportune in this time of dynamic change.
