How to Write a Pro-Glacier Book: An Earth Day Reading List Sveitarfélagið Hornafjörður, Iceland. Photo by beau mori on Unsplash. My writing is a product of my reading, so today, on Earth Day, I am pleased to share some of the books that inspired me to write On Time and Water. The theme of the book is, as the title says, time and water, and how all the elements of water that used to change on a geological scale of thousands or millions of years now change in a single human lifetime. Sometimes the issue is called "climate change," but that is just a term, and it comes nowhere close to expressing how large and serious the issue is. Some people think the phrase was actually coined to downplay the situation. The idea in my book is that this issue is larger than language, bigger than any words we use.
