Earth's Changing Climate (In Depth Science #5)

Earth was once a frozen snowball. And before that, a sea of lava. The Sun. Volcanoes. Glaciers. Meteor impacts. They've all played their part. The planet has changed. How do we know? Without humans, the Earth would cool. Massive sheets of ice would creep down from Canada. Sea levels would drop. Crops would fail. Instead, the Earth is warming. This will change how humans live. In some places, there will be storms. In others, droughts. Sea levels won't drop, they'll rise, flooding coastal cities. Corals will die, and with them, the fish and sea life that depend on them. What else will change? How can we stop it? Children will become tomorrow's adults. They will live with the choices we make today. This book, written for children ages 8 to 14, tells the story of Earth's climate and how climate change will impact every person on our planet. Understanding the science is the first step towards protecting their future. At the end of the book, activities bring the science to life: learn how to slow down climate change, study how greenhouses trap heat, "see" ultraviolet light, and make your own ice core!
