Polar Bear, Why Is Your World Melting?
POLAR BEAR, WHY IS YOUR WORLD MELTING?
By Robert Wells
Price: £10.99
The heat of the sun is trapped by the “greenhouse” gases that surround Earth - carbon dioxide, methane, nitrous oxide, and water vapour. If there is just the right amount of these trapped gases, the air is warm enough for plants, animals, and people to thrive. But now there is too much greenhouse gas, especially carbon dioxide.
Polar bears, and all of us, are in trouble. Robert Wells shows why so much carbon dioxide is going into the air and what we can do to help keep Earth cool.
