As Kudlinski showed children in Boy, Were We Wrong about Dinosaurs! (2005) and Boy, Were We Wrong about the Solar System! (2008), science is a process rather than a fixed body of knowledge. The most recent volume in the series looks at changes in ideas about weather and climate. According to Kudlinski, the ancient Greeks thought that the weather was determined by earth, air, wind, and fire, but scientists now explain that weather is affected by the sun's heat, the Earth's spin and tilt, and many other factors. And while today's instruments and knowledge help with weather prediction, climate change has added a new degree of uncertainty. The clearly written text moves along at a good pace. While the colorful digital illustrations can seem busy, many offer visually interesting perspectives. With its unusual slant on the topic, this picture book would be an intriguing supplementary title for classroom units on the weather. And if kids come to the conclusion that experts can be wrong, well, a bit of skepticism is a useful thing.

Gr 2-4 Following the pattern established in earlier titles, Kudlinski uses the refrain "Boy were we wrong" to contrast weather misconceptions throughout history with modern-day understandings. She explores the meaning of terms such as meteorology and hurricane , which originated from ancient beliefs and misguided theories, and she explains that some myths and legends contained elements of truth. Accessible information is presented concisely, and the clever, humorous tone of the text complements Serra's lively, engaging cartoon illustrations. There is plenty here to inspire even the youngest readers to seek out more material about the subject. The author encourages kids to become involved with tackling global warming and to see themselves as potential scientists. VERDICT A valuable resource for report writing and pleasure reading alike.
