Global Warming

Global Warming

"The history of Earth has been a history of temperature change; people and animals have historically moved to better climes, richer pastures, and areas of more abundant food. The problem now is that "somewhere else" is already occupied; meanwhile, temperatures appear to be rising, with foreseeably disastrous consequences. The gases in the air which cause the greenhouse effect have made life possible; too many gases, however, and catastrophe looms. Observation, historical records, and computer models lead to the conclusion that temperatures are rising, though no one can be certain how high they will go, or when, or what will happen. Low-lying areas will be under water, of course, as ice melts and sea levels rise; diseases and predators will proliferate; rains will increase in some parts of the world, while drought strikes elsewhere and mass starvation results."

How is Science Pursuing New Energy Technology and Alternative Energy Sources?

How is Science Pursuing New Energy Technology and Alternative Energy Sources?

"The global demand for energy is ever-increasing; however, the ability to fairly meet this demand now and in the future is rapidly diminishing. This episode tackles the pressing issue of what can be done to break away from dependence on imported liquid transport fuels. Viewers will find out what research scientists in New Zealand are doing in the field of new energy technology and what discoveries have been made in their search for alternative energy sources."
