Global warming, driven by the rising concentrations of greenhouse gases like carbon dioxide (CO2), presents a critical threat to the planet's climate. Carbon sequestration, the process of capturing and storing CO2, offers a promising solution to mitigate the impacts of climate change. This article explores the two primary forms of carbon sequestration?biological and geological?and discusses their role in reducing atmospheric CO2 levels. Biological sequestration, through plants and soils, naturally absorbs carbon, while geological sequestration stores CO2 deep underground in secure formations. Despite challenges such as high costs, public acceptance, and scalability, carbon sequestration remains a key tool in global climate strategies. With continued advancements in technology and international cooperation, it holds significant potential to help achieve net-zero emissions and limit global warming, making it a crucial weapon in the fight against climate change.
