Noted science writer, Andrew Bridges, tells the fascinating story of our changing air. Earth's atmosphere is all around us. It is wrapped around Earth like a blanket. It keeps us warm. It protects us from the Sun's harmful rays. Life just wouldn't be possible without it. But for the last two centuries, humans have been changing the air. We've been adding gases to the atmosphere that are making our planet warmer. This is changing Earth's climate. And it's affecting not only our air, but also our oceans, our ecosystem—and us. Packed with dozens of full-color photographs and illustrations.
For readers ages 9 and up.
