A 2019 video revealed a frightening climate truth: a 2°C global temperature increase, labeled the "threshold of catastrophe," represents the best-case scenario. Without immediate action, the planet is on track for a 4°C rise this century, risking $600 trillion in damages, doubled warfare, and a refugee crisis 100 times worse than the Syrian exodus.

David Wallace-Wells, who explores even higher increases like 8°C and 13°C, stresses that these horrifying predictions should not induce complacency. Instead, he urges a more intense focus on the issue.

He asserts that global stories are vital to cultivate equal empathy for individuals worldwide, from Bangladesh to Paradise, California.

Climate change is now primarily a political challenge, not just a financial one. While decarbonizing our economy demands trillions in new investments, public opinion increasingly favors action.

Climate change is now primarily a political challenge, not just a financial one. While decarbonizing our economy demands trillions in new investments, public opinion increasingly favors action. The responsibility now rests with elected leaders.

David Wallace-Wells, a national fellow at New America and deputy editor at New York magazine, explores these themes in his book, *[The Uninhabitable Earth: Life After Warming](https://goo.gl/ih35YX)*.

The climate crisis is not a future problem, but an urgent, immediate threat. In the last thirty years, we've released more carbon than in all prior human history, pushing our planet to the brink.

The climate crisis is not a future problem, but an urgent, immediate threat. In the last thirty years, we've released more carbon than in all prior human history, pushing our planet to the brink. Yet, climate action is often dismissed as a secondary concern.

New York magazine's David Wallace-Wells vividly illustrates the devastating human costs and irreversible planetary damage climate change will bring, sooner than we realize. He issues an urgent call to fundamentally change how we perceive and discuss our planet's future.

Sustainable Today visited Oregon State University's Wallace Energy Systems and Renewables Facility (WESRF). Lab head Annette Von Jouanne showcased the Wave Energy Linear Test Bed and a wave energy device developed with Columbia Power Technologies. This facility is a hub for renewable energy, wave power, and sustainability research.

Green colonialism impacts the Indigenous Sámi of northern Europe, with large-scale renewable energy and conservation projects built on ancestral lands without full consent. Wind farms, “green” mineral mining, and hydroelectric dams disrupt traditional livelihoods like reindeer herding. Framed as sustainable, these projects often dispossess Sámi, marginalizing their knowledge, rights, and self-determination for climate action. This issue was investigated by Tristen Taylor, Ingrid Gercama, and Nathalie Bertrams in “Green Colonialism: How New Mines in Sweden Threaten the Sámi.”

An image shows Sámi reindeer herder and joik singer Lars-Ánte Kuhmunen in a corral near Rensjön, Sweden, photographed by Nathalie Bertrams. Kuhmunen's 2005 album, "Birrasis," produced by Georg Buljio, is used with permission.

In his talk, David Wallace-Wells discusses his book, "The Uninhabitable Earth: Life After Warming," which distills complex climate science into human-scale impacts. He explores how to address climate change without succumbing to despair and the potential of technology for both mitigation and adaptation solutions.

Wallace-Wells, deputy editor of New York Magazine, expanded his 2017 article into this full-length work. The book details the effects of climate change on water, food, oceans, and more, guiding readers to understand societal impacts and inspiring action to prevent the worst outcomes.

David Wallace-Wells observes that few Silicon Valley titans are addressing climate change, despite the opportunity to leave a significant legacy. He points to Bill Gates-funded negative emissions technology, which could enable current industrial activity without global warming.

This technology would cost $3 trillion annually to operate worldwide. While substantial, this figure is less than the $5 trillion spent each year on global fossil fuel subsidies.
