NOT AS GOOD AS PLANET EARTH
With some exceptions this appears to utilize outtakes from PLANET EARTH. The theme is good, the evolution of the earth, but it is not as strong a presentation as the venerable LIFE ON EARTH or more recent PLANET EARTH. I am planning to give my copy to the local library or to my daughter's elementary school.

Understanding the Earth with science, not opinion
Dr. Stewart's latest contribution to science for the non-scientist continues his refreshing perspectives on the planet earth. If this video does not educate, enthrall, and entice you to learn more about our planet and its fragility, you must be one of those people who will not allow themselves to be confused with facts because your mind is already made up.

Once you get used to Dr. Stewart's Scots accent, his explanations of natural phenomena are remarkable for their clarity and simplicity. Even so, he does not condescend as he shares his wonderment at the most recent scientific discoveries that he presents in ways that compel the viewer to pay attention.

While some may contend that his topic includes "controversial" issues such as global warming, he never makes a statement without offering solid evidence. Indeed, his discussions are replete with references to the scientific recognition that they are theories that continue to evolve as evidence is accumulated. Thus, the only "controversy" would arise from the fact that the accumulating evidence tends to support scientific concerns.

For example, the evidence is uncontrovertible that Greenland's glaciers are melting at a rate never observed in modern times. Even so, Dr. Stewart includes the observation that scientists can only theorize about the consequences because they are unable to follow the melt water through the glacier and under the ice. Hence, scientists continue to explore and ask questions and postulate new theories ... because that is what good scientists do and that is what good science requires.

Anyone think that there is no problem if the frozen tundra warms up? Watch Dr. Stewart singe his eyebrows as he shows that the white stuff under the moss is methane by igniting it. So, how much methane would be released if (or when) the tundra warms up? And what will be the effect of this greenhouse gas? Watch the video.

Regardless of your political views on global conditions, this presentation offers the serious questioner the most recent research available. It could cause you to change your mind -- or, like a good scientist -- it could inspire you to find contrary evidence so that an informed dialogue will help us solve our planet's problems.

Last, but not least, so many interesting facts, theories, and supporting evidence are demonstrated that I was amazed at the organizational skills required to present so much information in only two DVD's. I include this video in my five-star list of videos that includes, among others, Blue Planet, Life on Earth, ... and Dr. Stewart's "Weather" -- which I also highly recommend.

Outstanding!
I have studied these subjects for many years now and generally very a very critical eye. I find absolutely no fault with these programs. Full marks to Dr. Stewart for all of his efforts.

overview of planet Earth
This is a very good visual introduction to Earth for anyone whose interests are not directed to the physical and biological sciences. The videography is vivid and captivating. Overall, it is well executed.

Wonderfully done and educational!
Saw this originally on TV, and wanted it in my video library. There are so many things on this earth to learn about, and this was a fantastic way to increase that knowledge!
