This book provides a nice, digestible overview of climate change for the interested young person or adult. It covers the history of earth's climatic changes since our planet was formed, while focusing on how human activity that combusts fossil fuels (oil, gas, coal) has raised carbon dioxide concentrations in our atmosphere from around 280 parts per million in the 1700s to now over 400 parts per million, with far-reaching consequences for life on earth. These consequences include a warming planet, coral bleaching and die-off, more heavy rainfall events causing more floods, more likelihood of droughts and heat waves, increased wildfires, melting of permafrost and in some cases the costly relocation of Arctic villages, famine resulting from crop failures, and more. The book ends on an empowering note, asking the reader how they will help be a part of the solution. It's a quick read that can be completed in under an hour.
