Preface: Earth Observations for Addressing Global Challenges

Abstract

As climate change has been of great concern worldwide for many years, addressing global climate challenges is the most significant task for humanity. Thus, the Group on Earth Observations (GEO) has launched initiatives across multiple societal benefit areas (agriculture, biodiversity, climate, disasters, ecosystems, energy, health, water, and weather), such as the Global Forest Observations Initiative, the GEO Carbon and greenhouse gas (GHG) Initiative, the GEO Biodiversity Observation Network, the GEO Blue Planet, and so on. Related topics have been addressed and deliberated throughout the world.
