What is the environmental change in the tundra?

Environmental change in the tundra is primarily driven by climate change, leading to rising temperatures and altered precipitation patterns. This warming causes permafrost thawing, which releases greenhouse gases like methane and carbon dioxide, further exacerbating global warming. Additionally, changes in vegetation and wildlife patterns are observed as species adapt to new conditions, disrupting established ecosystems. These transformations can have cascading effects on biodiversity and indigenous communities that rely on tundra ecosystems.
