Summary:
- This article discusses the research of paleontologist Neil Shubin, who has studied the impact of climate change on polar regions throughout Earth's history.
- Shubin's work has revealed how dramatic shifts in polar climate and environments have led to mass extinctions and the evolution of new species over millions of years.
- By understanding these past climate changes, Shubin's research provides important insights into the potential impacts of modern-day global warming on polar ecosystems and the species that inhabit them.
