Hot Earth Dreams

What will the Earth look like if severe climate change happens, and humans survive?

It is not an easy question to contemplate, let alone answer. If severe climate change happens, the Earth will continue to warm for centuries after we've exhausted our fossil fuels. Civilization will shatter, the great artworks and monuments vanishing as cities fall into rubble and coasts disappear beneath rising seas. There will be a mass extinction, coral reefs and ice sheets will disappear, and the survivors will migrate to new homes and habitats for generations as the climate continually changes. Only after hundreds of thousands of years will the climate to return to what we currently consider as normal.

Right now, this is our most likely future. Scary as it sounds at first, it is a future that is very much worth exploring. It's crazy, then horrible, then tough, and then increasingly strange. This clear-eyed overview weaves together the latest scientific research on climate change, mass extinction, collapse, and evolution, to describe a deep future that is ever-changing but very knowable.

It is very difficult to get a good picture of what the world will be like as the climate warms — not just the increasing temperatures and rising sea levels, but the knock-on effects of those. Massive ecological damage, including virtually all of our staple crops… massive supply chain disruptions as ports are flooded and weather becomes unpredictable… not good news for a globalized world.

Not a terribly cheerful book, given the subject matter, but eminently readable. Dr. Landis has kept the chapters short enough that each one could be a single lesson.

I used chapters from this book to help set the scene for students. The reading level is perfect for teenagers: scientifically accurate without being technical.

Frank Landis is a professional botanist and ecologist working in California.

He is interested in putting the life back into science fiction and fantasy, and he likes looking at how humans relate to the natural world, how sustainable societies work, and writing, and (primarily) writing fun stories for people to enjoy. He also writes non-fiction, primarily botanical essays such as the ones posted on his blog.

When not writing, he works on conservation and sustainability issues.
