This process, known as climate change, is caused mainly by human activities, especially CO₂ emissions. To avoid the worst impacts of climate change, we need to both reduce emissions and remove excess CO₂ from the atmosphere.

Global warming, caused by increasing greenhouse gas emissions, threatens biodiversity. As temperatures rise, species struggle to adapt, leading to extinctions and ecosystem disruptions. Melting ice contributes to sea level rise, endangering low-lying habitats. Additionally, increased carbon dioxide levels affect plant growth and biodiversity, potentially exacerbating climate change through feedback loops. Urgent action is needed to address these challenges and protect our planet's diverse ecosystems.
