Host Peter Tonge visits with Wayne Schoech of New England Bonsai Gardens who offers suggestions on how to care for bonsai (ancient Oriental art form of miniaturizing trees and shrubs) when you bring it home. Mark Heinlein, also from the Gardens, transforms a three-year-old juniper into an ancient, windswept tree in 25 minutes. Originally aired as an episode of "The Good Green Earth."

The tourism industry not only generates significant revenue for locales but also contributes to climate change. Currently, it is estimated that the tourism industry generates about five percent of total greenhouse gas emissions. The percentage is expected to increase by eighty percent by 2035. Climatic conditions are considered a decisive factor attracting people to different geographic areas. However, destinations are beginning to suffer environmental changes as a consequence of tourism.

New research reveals that loss of sleep leads to increased anger. Researchers are now studying the link between loss of sleep and aggressive behavior. Other segments include bacteria that consume greenhouse gases, a handy robot glove, and drones mapping marine megafauna. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Year after year massive fires continue to rip through the wildland-urban interface (WUI) in Colorado. Some scientists fear that the forests may not be able to recover due to a warming climate. Colorado University PhD student Monica Rother investigates post-fire ecosystems in an effort to predict what the Colorado Front Range might look like in a warmer, drier future. Part of the WildFire PIRE series.
Host Peter Tonge visits with Paul Rogers of Stonehedge Nursery who offers tips on growing culinary herbs from seeds indoors on a windowsill. Also shows how to identify soil type with a basic 10-minute test. Looks at some of the organic additives you can use to improve your soil. Originally aired as an episode of "The Good Green Earth."
One of the areas showing the greatest impacts of climate change is Antarctica. These impacts are significant because Antarctica serves as the regulator of global climate patterns and helps redistribute heat throughout the planet. Antarctica also greatly influences the circulation of the world’s oceans’ currents. Due to Antarctica’s influence on global climate patterns, scientists and other experts are working together to ensure the protection of Antarctica’s environment. Chapter 8 of Air: Climate Change Series.
Currently, cities have a fundamental role in the struggle against climate change and harmful environmental practices. But, at the same time, major global cities consume more than two thirds of the world’s energy and release seventy percent of the global emissions of carbon dioxide. Climate change has become part of the worldwide agenda for major cities as they develop policies and practices to protect the environment and reduce greenhouse gas emissions. Chapter 2 of Air: Climate Change Series.
Whether they arise from human causes or forces within planet Earth itself, natural disasters threaten life and civilization with what seems to be growing frequency. Studies troubling developments in marine, arctic, wetland, and urban environments while highlighting research opportunities that may help prevent future catastrophes. Coral reef decay, Everglades habitat loss, polar ice disappearance, and global warming are all analyzed. Looks at earthquake prediction, hurricane and tornado tracking, air pollution monitoring, tsunami warning systems, and the cleanup of toxic flood sediment in New Orleans.
One of the areas that is most sensitive to climatic change is human health. Climate change affects human health in numerous ways. Some are immediate, and others may not manifest until future generations inhabit earth. Global areas have already begun to suffer the effects of ecosystem alterations and limited water sources. These situations also impact crop production and food distribution. Researchers also predict an increase in the number of displaced persons as the planet warms and sea levels begin to rise. Chapter 10 of Air: Climate Change Series.
Mars is the planet in our solar system most similar to Earth. Rumors of life on it may be substantiated as NASA orbiters and rovers discover new evidence of frozen water just beneath the rusty soil. Did alien life exist there? As Earth reels with the effects of global warming, Mars becomes the most likely candidate for eventual human habitation. Cutting-edge computer graphics are used to show what life would be like on Mars, and to imagine what kind of life forms might evolve in alien atmospheres.
With today's high fuel costs, it is time to start looking beyond petroleum and into renewable resources to power vehicles. Ethanol is a clean-burning fuel derived from plants, primarily corn. It is combined with gasoline to produce a cleaner fuel that doesn't emit as many greenhouse gases as pure gasoline. Pure ethanol has not yet been approved to fuel vehicles, but it is the fuel of choice for racecars. By mixing gasoline with ethanol, fuel supply can be extended. Explores the production of ethanol and highlights the importance it holds in the "green power" movement.
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The spaceship runs out of water, and the kids urgently look for more. They arrive at a planet full of water, and the habitant that greets them tells them of great flood that almost made the whole continent disappear. Manuel asks Maqui about this phenomenon, and she explains the greenhouse effect.
David Stahle travels to ancient forests around the world, collecting tree rings to learn more about major climate and historical events dating back hundreds and thousands of years. With help from the National Science Foundation, he uses dendrochronology, or tree-ring dating, to get a snapshot of climate change over time. Stahle runs the Tree-ring Lab at the University of Arkansas, where he and fellow tree-ring researchers are learning that a trend of global warming began in the 1800s and continues today, brought about by changes in tropical sea surface temperatures of no more than a few tenths of a degree Celsius. Today Stahle is working with hydrologists and government planners in California and throughout Mexico to plan for drought and climate change events.
Welcome to the North Carolina State University (NCSU) Phytotron, a singular facility for growing plants under various combinations of strictly controlled environmental conditions. Scientists are able to conduct all types of plant research here, from studies of disease-resistant crops to drought-proof grasses to new biofuels. The NCSU Phytotron was built in the 1960s with support from the National Science Foundation (NSF), and was used a decade later to help prevent a collapse in the U.S. corn crop from fungal disease. Now, after more than a generation of such research breakthroughs, the Phytotron has received additional support from NSF for a 21st century makeover. The renovations include a new Biosafety Level 3 (BSL-3) lab with a greenhouse that houses high security research, such as experiments with viral and bacterial pathogens. Part of the National Science Foundation Series “Science Nation.”
