Earth's climate change

de James Bow

"We live in an energy-rich age, in which we can turn on a light with the flick of a switch or drive anywhere by turning a key. But, our vehicles, factories, and power stations, which create the electricity needed to light and heat our buildings, pump carbon dioxide into Earth's atmosphere. Carbon dioxide overload from these human activities is making our planet hotter and hotter--and is causing the Earth's climate to change. Find out what scientists are doing to find sustainable new forms of energy that will secure our planet's future."--
