    GLACIERS AND ICE CAPS: THE MELTING

    The change from a solid state, snow and ice, to a liquid state, water, makes the Arctic sensitive to climate change and introduces many dangerous positive feedback loops that can drive sudden detrimental climate shifts. Detrimental climate shifts that can affect the whole planet and human civilization. Includes interviews with leading glacial experts from around the country.

    Chapters:
  • Introduction - Experts describe the dangerous impacts of global warming on the cryosphere, the world of ice
  • The Arctic and Antarctica - Presents the locations of the world's great ice sheets and polar caps
  • The Warming of the Arctic - Tells why the Arctic is especially sensitive to global warming
  • The Melting Ice Caps - the shrinking of the ice caps speeds up global warming
  • Thawing of the Permafrost - the melting of permafrost puts additional carbon dioxide into the atmosphere, further accelerating global warming
  • Melting of Glaciers and Ice Sheets - Predicts how the melting of glaciers will raise sea levels dramatically by 2050

    CORE GEOLOGY

    Not since the discovery of gold in 1848 has the understanding of the world's geology been more important to the welfare of the nation.

    Throughout history the rise and fall of civilizations has been propelled by the abundance and scarcity of valued resources. At no time has this been truer than in the 21st century. Whether it is the search for oil or silicon to make microchips or uranium to run power plants, the search is directed by geologists. In Core Geology, the building blocks of this most contemporary science are laid out in a logical order, including the meaning of the fossil record.

    Chapters:

    1669 - The Geological Laws - With brilliant reasoning, 17th century Danish naturalist Nicolas Steno deduced the three fundamental laws of geology that would become the basis for this science to the present day.

    1812 - Properties of Minerals - The identifying properties of minerals are laid out including Mohs hardness scale.

    1830 - Geology Occurs by Natural Processes - By the middle of the 19th century, it was understood geologists that forces that shaped the earth are the same ones occurring today.

    1833 - The Three Types of Rocks - Igneous, Sedimentary and Metamorphic - The three rock types are defined and illustrated.

    1837 - A Past Ice Age is Theorized - Many of Earth's features were a mystery until it was discovered that they were produced by massive ice sheets that periodically cover much of the planet.

    1907 - Radioactive Decay is Used to Date the Earth- This chapter tells the story of how modern physics is used to date the earth.

    1912 - Alfred Wegener Proposes Continental Drift Theory - Mountain building, the shapes of the continents, volcanoes and earthquakes are explained by the theory plate tectonics.

    1972 - Ancient Life and the Fossil Record - How fossils are formed, their age and how the fossil record sheds light on evolution is presented in this chapter.

    GLOBAL WARMING: THE RISING STORM

    Presented and narrated by Bradley Whitford.

    How much irreversible change to our atmosphere has already occurred? Can we control the devastating effects that the burning fossil fuels will cause? If there is not an immediate global initiative to save the planet, what will the future hold?

    In the last half of the 20th century, scientists began understanding that industrialization and the effects of explosive population growth were affecting the fundamental structure and composition of earth's atmosphere. Man's ever-increasing thirst for energy, quenched by the burning of fossil fuels, has dramatically increased greenhouse gases in the lower atmosphere. We are now experiencing the first impact of these accumulating gases: A general warming of the planet. This 2-disc set examines and explains this phenomenon, and looks into the future where other, more deadly impacts are predicted to follow. In the first decade of the 21st century, we find ourselves at the precipice of a dangerous, rising storm.

    GLOBAL WARMING: SCIENCE AND SOLUTIONS

    Presented and narrated byErick Avari.

    Our planet is warming; it's significantly warmer in the 21st century than it was in the last third of the 20th century. Indeed, four of the warmest years on record have occurred in this century. This global warming is being forced by the unabated burning of fossil fuels pouring CO2 into the atmosphere ... And this warming appears to be forcing dramatic regional and worldwide climate shifts. This series takes you through the Science of Global Warming and the Solutions. We need only to trust the science and work together to implement these solutions... solutions we can no longer afford to ignore.

    BEYOND GLOBAL WARMING

    The reality of climate change is beyond any doubt. The most dramatic upheavals are occurring in polar regions, where northern communities are facing unprecedented changes.

    The Canadian coast-guard ice breaker Amundsen, transformed into a floating laboratory, is taking a team of scientists on an expedition through the Canadian Arctic. Their research is vital in understanding the climatic changes in the context of the geologic history of the region and in anticipating the oncoming shock to the ecosystem and local communities.

    Beyond Global Warming explores the development opportunities global warming will bring to the Canadian Arctic, making it a key region of international diplomacy in the next few decades. Will this frozen land become the New World of the 21st century?

    TIPPING POINT, THE: GLOBAL WARMING AT THE ARCTIC CIRCLE

    The Arctic Ice Sea, a plate of ice roughly the size of Europe, is disappearing. This film takes us on an ice breaker, in the company of scientists, through the fabled Northwest Passage. With our own eyes we see how polar bears, seals and arctic birds are struggling to adapt to the rising temperature and their shrinking terrain. But beyond our concern for the wildlife, there are very worrisome concerns about the effect on human life of the melting ice cap.

    The thawing permafrost will release methane into the atmosphere which, an expert tells us, is like a bomb that will explode. Also, the carbon released from the permafrost will further heat the atmosphere, advancing global warming.

    The immediate worry is that the melting sea ice will intensify the extreme weather caused, bringing more violent storms and cyclones to some regions and longer droughts to others.

    The Canadian Coast Guard predicts that it will not be long before the infamous Northwest Passage will be completely ice free. The political and economic implications of that are dramatic. The business world is eyeing the vast oil and mineral reserves locked beneath the melting ice. Several Arctic shipping routes, including one across the North Pole, are being seriously considered. It does seem like the five Arctic powers ¡V Norway, Russian, Canada, Denmark and the United States- will be scrambling for strategic advantage in an area that could, at some point, provoke war.

    GLOBAL WARMING: TIPPING POINT

    What is global warming? What is the evidence for it? How will it affect the world? This film explores these questions as it follows the icebreaker Louis St Laurent on a trip to the Arctic Circle.

    The Arctic Ice Sea, a plate of ice roughly the size of Europe, is disappearing.

    Scientists say that by 2013, there will be no sea-ice left in the Arctic, causing a tipping point for climate change throughout the world.

    Polar bears, who are at the top of the Arctic food chain, are feeling the heat. As the sea ice shrinks, so does their world.

    The forests of Alaska are suffering, too. Alaska's vast pine forests rest on a layer of solid permafrost and when the frost melts the ground literally gives way. Melting permafrost could soon be a worldwide disaster.

    "The Arctic will export change to the rest of the world," warns one expert, "Melting sea ice will intensify the extreme weather caused by climate change, bringing violent storms and cyclones."

    Very quickly the world's food and water supplies will begin to run short.

    Canadian coastguards predict that it will not be long before the legendary Northwest Passage through the Arctic will be completely ice-free. And that's fuelling a new "cold rush" as businesses eye the vast oil and mineral reserves which, until now, have been locked beneath the melting ice.

    Says one commentator: "This issue will become something that people are willing to go to war over."

    A critical concern for the planet today is global warming and its probable consequences. And whether warming trends are occurring because of greenhouse gases in the atmosphere or a cyclical change in the weather, we'll investigate this global issue from the polar Arctic to the polar Antarctic.
