From his garage in a San Roque neighborhood in Santa Barbara, “doomer” Eliot Jacobson shook up the world.

Jacobson, a retired mathematics and computer science professor, tweeted to his 37,000 Twitter followers a chart that he created that showed a sudden rise in ocean temperatures.

The tweet caught the attention of the climate science world, with stories about his work appearing in the Los Angeles Times, Forbes, and the PBS News Hour.

Eliot’s message to the world: We’re doomed.

“There is absolutely no way out,” Jacobson says on the latest episode of Santa Barbara Talks with Josh Molina.

In the podcast, Jacobson talks about how humans have bought into the “the big green lie.” Watch the full, unedited podcast by clicking on the YouTube link below.

“We are going beyond any notion of what environmentalism means when we say that green technologies are part of the environmental movement,” Jacobson said. “The whole idea of environmentalism was to protect the environment, and it has been corrupted by this new idea that if only we create these new energy sources, then that will help us save the environment.”

He noted desert wastelands of wind and solar energy, and how the ocean floor is scraped for lithium to power electric vehicles and bikes.

He said that humans don’t create new energy to replace old energy.

“The more energy we produce, the more each of us uses,” Jacobson said. “We don’t replace old energy with new energy. We use new energy for new things.”

Jacobson said humans live in a world of unlimited growth. For example, he said, humans want larger incomes, a better job, a nicer house, more stuff, a larger savings account, and at a time when the population is growing.

“The reality is that the planet is not capable of sustaining growth,” Jacobson said.

He said that people who hope the planet gets better by converting to green technology have deceptive expectations.

“Whether that thing is transition to electric vehicles, and solar, wind, whether it’s to get this or that political party elected, or persecute that political politician, whatever that is, everything is focused on this paradigm, this hoax that we can have unlimited growth.”

Jacobson said a “doomer” rejects hope, and the concept of deceptive expectations.

“The opposite of hope is not hopelessness,” Jacobson said. “The opposite of hope is not fear or inaction. The opposite of someone who has hope for our future is someone who has realistic expectations.”

As a “doomer,” he said, he simply has realistic expectations for the planet going forward.

Jacobson walks dozens of miles a week and considers himself an activist. He says humans are focused on taking action for humans, to save humanity, but that it is too late.

“What is my activism?” Jacobson said. “It is to preserve this planet for whatever is coming next. I look to the natural world. I look at what I can do as an activist to save the natural world. I don’t look at what I can do to save humanity.”

Jacobson said humans are experiencing the sixth extinction, and that we are already seeing massive heat waves and famine in parts of the world.

Eventually, he said, there will be waves of climate migration as people leave areas that lack water, food supply, and are burning out of control.

“When you talk about when, my answer is it’s already happening,” Jacobson said. “It’s nice to live in Santa Barbara, isn’t it?”

Although he’s a “doomer,” Jacobson lives his life based on three rules: “kindness, generosity and service.” He is a volunteer for a variety of community organizations and believes in helping others.

“I want to live my life with kindness toward all people, toward all beings, toward all life.”
