We all hear a lot about global warming and the challenges that it creates for our generation and the generations to come. How do we know about global warming and its impact on our changing climate? The answers are in this book. The Baltimore oriole is beginning to summer farther and farther north than ever before. The leaves on the maples and oaks are turning colors later and later into the fall, and the maples are moving north, following the warmer climate. The cherry trees in Washington are blooming earlier than even thirty years ago. Polar bears "are not surviving well, and some cubs are "being born smaller than before." What other clues lie in the world around us? What can a child do to make a difference?
