Our Finite Planet
Earth has endured and survived extreme climate change more than once, with varying impacts on natural life. This time is different. We know the history. We know what’s happening and the impact of our own actions. We understand the limits to crucial resources and what will happen if we do nothing. Most importantly, we have the ability to correct our course in pursuit of a viable future. Are we up to the challenge?
There Is No Planet B
“We got here according to the laws of physics. There are no miracles, we are now in charge.”

A Short History of the Climate and Extinction
In the history of the Earth, stretching back billions of years, has there ever been a time when the climate was changing as it is today, and can such a time show us exactly what will happen next? The short answer is no.
The Climate at the Birth of Homo Sapiens
Modern Humans, Homo sapiens, have existed for perhaps 300,000 years, and maybe longer. But agriculture and civilization only started about 10,000 years ago. What took so long?
The Climate on the Eve of Civilization
Between twenty and ten thousand years ago the Earth’s orbit changed, increasing the solar energy reaching the planet by more than 10%. This set into motion a series of feedbacks that caused the Earth to warm, enabling the birth of agriculture—and civilization.
The Human Footprint: The Causes and History of Climate Change
Like other animals, on some level humans have always understood our dependence on the weather and the changing seasons. Modern climate science, a combination of many disciplines, has given us knowledge of how the weather and the seasons now depend on us, and about our own outsized impact on our finite planet.
The Rocky Road to a Sustainable Future
As Nathanial Rich points out in his book Losing Earth, “There can be no understanding of our current and future predicament without an understanding of why we failed to solve this problem when we had the chance.”
