Arctic ice is melting, sea levels are rising, and glacier are shrinking at alarming rates. The Earth is getting unmistakably warmer. But is this vast, potentially catastrophic, climate change the result of human behavior? Or is it simply the Earths natural cycle of warming and cooling periods that have occured since the planet formed? The History Channel offers an in-depth study of the science behind this hot-button issue.

Scientists explore the skies to examine the warming effects of the sun and dig deep into the Earth to study continental movement and volatile activity at the planets core. Experts speculate on how natural events, including volcanic eruptions and massive meteor impacts, have affected temperatures and weather systems over the planets 4.5-billion-year history.

Shot on location at some of the most breath-taking locations on the planet, and filled with dynamic special effects, A Global Warming? is a captivating look at the Earths climatic evolution and a study of the longevity of our planet - and mans future on it.
