This important book shows how the use of fossil fuels is changing Earth’s climate and what scientists are doing to find sustainable forms of energy that will secure our planet’s future. We live in an energy-rich age that relies heavily on the burning of fossil fuels. We burn fossil fuels to power our vehicles, factories, and even our power stations, which burn fossil fuels to create the electricity needed to light and heat our buildings. The result is a buildup of carbon dioxide into Earth’s atmosphere. Find out how carbon dioxide overload is making our planet hotter and hotter and what is being done to fight global climate change.
