Ce livre explore l'accumulation de CO2 dans l'atmosphère, résultant de l'équilibre entre émissions et absorption. Il souligne l'importance de comprendre le bilan carbone mondial et les transformations nécessaires dans l'utilisation des terres pour atteindre les objectifs climatiques d'ici 2030. Les impacts humains sur le climat sont également abordés.
Concepts, Solutions and Experiences
Understanding the global carbon budget is crucial for addressing climate change, as it links anthropogenic CO2 emissions to atmospheric concentrations. Current climate goals emphasize transforming land-use sectors into carbon sinks by 2030, with a focus on enhancing these sinks in subsequent decades. Human activities have significantly warmed the atmosphere and ecosystems, leading to unprecedented changes over the last four decades. The scientific community has documented these shifts, prompting the G7 to advocate for expert study on climate change since the mid-1980s.
