It is hot outside? Why does it rain? Are tornados and twisters the same thing? The wonders of weather are explained to young children.

Photos of puffy clouds, dramatic storms, and rainbows alternate with buoyant portraits of a diverse group of children experiencing the natural world. Seasons, precipitation, wind, clouds, storms, and climate change are all introduced in a format that younger children can grasp from a trusted name in children's nonfiction.

From the author-photographer behind the celebrated Hello Seasons! series, What's the Weather? continues Shelley Rotner's exploration of the world around us. Rotner has also worked as a National Geographic photographer and is a former kindergarten teacher. Back matter includes a statement from a climatologist and a thorough glossary.
