Impact of Climate Change on Permafrost

The video explores a tunnel in Alaska that reveals ancient plants and extinct animal bones, providing insights into past climate conditions. Scientists study permafrost to understand its impact on climate change and infrastructure. Melting permafrost releases carbon, exacerbating climate change. The video also discusses the construction of a pipeline in 1977, highlighting its environmental considerations and the broader implications of crude oil consumption on permafrost.
