Why are we worried about the amount of carbon in the atmosphere?

We are concerned about the amount of carbon in the atmosphere because elevated levels of carbon dioxide (CO2) and other greenhouse gases contribute to climate change, leading to severe environmental impacts such as rising temperatures, extreme weather events, and sea-level rise. This disruption can harm ecosystems, agriculture, and human health, threatening food security and livelihoods. Additionally, increased carbon levels can exacerbate air pollution, further impacting public health. Reducing atmospheric carbon is essential for mitigating these risks and ensuring a sustainable future.
