Arctic ice is melting, sea levels are rising, and glaciers are shrinking at alarming rates. And the Earth is getting unmistakably warmer. But is this vast, potentially catastrophic, climate change the result of human behavior? Or is it simply the Earth s natural cycle of warming and cooling periods that have occurred since the planet formed? The history Channel offers an in-depth study of the science behind this controversial, 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 the volatile activity at the planet s core. Experts speculate on how natural events, including volcanic eruptions and massive meteor impacts, have affected temperatures and weather systems over the planet s 600-million-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 Earth s climatic evolution and a study of the longevity of our planet--and man s future on it.

If this doesn't get your attention, nothing will...
Al Gore's "An Inconvenient Truth" got all the hype and awards. The History Channel's "A Global Warning?" only gets the Joe Friday award - "Just the facts, ma'am, just the facts."If you want to understand why global warming is real and why we need to address the issue now, this is your documentary. It is substance, substance, substance. No grandstanding, no histrionics, no tear-jerking moments. Just a carefully made and compellingly presented factual case for global warming and the possible/probable outcomes from failing to address it.This is what I thought I was going to get with "An Inconvenient Truth", which is riddled with Al Gore self-aggrandizement and self-pity.If you want to watch an Al Gore 'feel good' show, get "An Inconvenient Truth". If you want to understand the scientific case for global warming, this is the real deal.

No Poltics in the Way
This is a great overview on the findings of past global climates, and how the past could be the tell-tale of future occurrences. The great part of this movie is that it also delves into how the past climates are found... it scratches the surface on each technique, and only gives examples in one area of findings, but the amount of information in this movie makes it a necessity. As a high school Earth science teacher, this is a staple for my classroom. The information is invaluable, and the students are no longer bounced around the topic politically, like a ping pong ball. Again, this is a lot of information, so i split it into two days... most movies require an accompanying worksheet front and back, this movie takes two front/back worksheets.

not balanced.
A love story for the man-made or anthropogenic crowd. Uses many many adjectives to describe the dire consequences that are "just around the corner."No balance at all. Al Gore would love this DVD.I gave it a second star because it did spend considerable time discussing temperature variations over the past several hundred million years. This may help the folks who believe that the earth's temperature has not changed for the past billion years.Even the packaging was poor. Worst I have ever encountered.

Documentary film review
' A Global Warning ' (History Channel Documentary) was well-organized with a wealth of supporting scientific evidence. I also found it to be balanced in its perspective indicating global climate change is influenced by both natural events and human-induced activity.

Reality speaks...this is EXCELLENT
This is one of the best, most extensive documentaries I've seen. So many concepts, once only theories, have now been proven. Those who view this will have a different view of what, in reality, is going on. How wonderful if everyone on this planet could view and understand this great production. Cutting edge information.

Great
This review of climate change over millions of years explains several reasons for climate change as well as the scientific evidence documenting it. It does discuss the effect of humans on climate without downplaying it but also without bashing humanity completely.
