Dirty Secrets, Earth’s Atmosphere, Cauldron Earth, and Oil

Here are a few new DVDs on the library’s shelves. I hope you stop by and check them out.

Protecting earth’s atmosphere:Earth is the only planet known to support life. The primary reason is a mixture of different gases, known as the atmosphere. These gases, along with the sun, warm our planet to an average temperature of 15 degrees Celsius. This delicate process is known as the greenhouse effect. Without it, the sun’s energy would escape back into space leaving the earth frozen. In this edition of Science Screen Report, we learn about the earth’s atmosphere, climate, and the greenhouse effect. We explore the impact human activity is having on our atmosphere, and ways scientists believe we can prevent further destruction to the atmosphere, and allow our planet to continue to thrive.

Dirty Little Secrets: Program studies fine particle air pollution and its public health hazards

What if The Oil Runs Out?:This film follows a middle-aged, Midwestern couple through violence at gas stations, conflicts with neighbors, and the loss of their livelihood; it also focuses on their daughter, an oil prospector determined to find new crude oil fields in the Alaskan National Wildlife Refuge. Interspersed with the docudrama are notable statistics on oil production and consumption as well as real-world interviews with former Pentagon energy security adviser Paul Domjan, Centre for Global Energy Studies chairman Sheikh Ahmed Zaki Yamani, and other experts

Cauldron Earth:This program shows how research into the chemical makeup of geological and biological materials drives the innovation of energy systems, building methods, and transportation technolog–and how these improvements can save lives and reduce stress on the environment. Hydrogen fuel cells, resin coatings for giant wind turbines, wax-plaster mixtures for energy-efficient home–the video features these and many other advances, suggesting a future in which humanity can both profit from and protect the Earth
