This highly-acclaimed climate change education title, winner of twelve book awards, is now available in paperback! When the weather changes daily, how do we really know that Earth's climate is changing? Here is the science behind the headlines - evidence from flowers, butterflies, birds, frogs, trees, glaciers and much more, gathered by scientists from all over the world, sometimes with assistance from young citizen-scientists. And here is what young people, and their families and teachers, can do to learn about climate change and take action. Climate change is a critical and timely topic of deep concern, here told in an age-appropriate manner, with clarity and hope. Kids can make a difference! This book combines the talents of two uniquely qualified authors: Lynne Cherry, the leading children's environmental writer/illustrator and author of The Great Kapok Tree, and Gary Braasch, award-winning photojournalist and author of Earth Under Fire: How Global Warming is Changing the World
