Ecofascism and Rewilding: A Conversation With Ariel Kroon and Christina De La Rocha

Season 2, Ep. 10

There’s no question that the biosphere is in crisis right now thanks to human-driven global warming, our hostile takeover of most of Earth’s land area, and our pollution and overfishing of the seas. Slowing down—never mind outright stopping—the collapse of the Earth’s ecosystems and the mass extinction currently gaining pace calls for aggressively protecting the environment, or possibly even giving half of the Earth’s land surface back to nature in a process known as rewilding. 

But how will we manage to share the Earth with the rest of the biosphere when history shows that we’re pretty terrible at sharing it with each other, with some states even going so far as to have used the preservation of wilderness as a tool of genocide and white supremacy? There are still those who would use environmental protection as an excuse to block immigrants, reject refugees, and expel “undesirable” people from the land. What will it take to value human and non-human life and the land all equally, without using one as an excuse to persecute the other?

Getting urgently-needed environmental protection and rewilding right requires facing the evils that have been historically committed in the name of conservation, so that we don’t repeat those grave mistakes, even with the best of intentions. As solarpunks, we need to learn from the past in order to shape futures that are intentionally better than our pasts and presents.

And that’s a wrap for season 2! Season 3 will be coming along in the last week of June for Patreon supporters, and to the public in the first week of July. Until then, keep dreaming, and keep up the good work!

50 Million Years of Climate Change

Season 2, Ep. 8
Have you ever thought about how dinosaurs lived on a warm, swampy Earth and how we live on one that’s cold enough to keep pretty much the entirety of Greenland and Antarctica buried under kilometers-thick sheets of solid ice and wondered, hmm, how did we get from there to here? The short answer is that it took 50 million years of declining atmospheric carbon dioxide concentrations and dropping temperatures, not to mention building an ice sheet or two. For the longer story of the last 50 million years of climate change, including some of the reasons why, catch this episode of our podcast with Dr De La Rocha! You’ll hear about plate tectonics and continental drift, silicate weathering, carbonate sedimentation, and the spectacular effects the growth of Earth’s ice sheets have had on Earth’s climate. There are also lessons here for where anthropogenic global warming is going and whether or not its effects have permanently disrupted the climate system. Fun fact: the total amount of climate change between 50 million years ago and now dwarfs what we’re driving by burning fossil fuels, and yet, what we’re doing is more terrifying, in that it’s unfolding millions of times faster. Bonus content: If you want to see sketches and plots of the data discussed in this episode, you can find them here.!!Nerd alert!! If you're interested in the primary scientific literature on the subject, these four papers are a great place to start.Dutkiewicz et al (2019) Sequestration and subduction of deep-sea carbonate in the global ocean since the Early Cretaceous.

Science and Christianity: Is There a Conflict? With Norm Nelson

Season 2, Ep. 7
Although the battle lines have shifted down through the years from heliocentrism to evolution (and let’s not get started on the age of the Earth), it feels like there’s a fundamental conflict between science and religion, especially with respect to the Abrahamic religions like Christianity and Islam. I (Christina), the host of this podcast episode, as a scientist and atheist who tends to assume all scientists are atheists—because how could they not be?—am definitely guilty of thinking this.Yet, there is a long tradition of curiosity, inquiry, and, yes, science within the Abrahamic religions and no shortage of devout scientists working hard to this day to understand the workings of the world and cosmos. I decided that it was time to confront my assumptions by talking to one of my religious colleagues. Thank you in advance to Dr Norm Nelson—an oceanographer whose Christianity is a core part of his life—for discussing whether or not there is a conflict between science and Christianity, and where the roots of that conflict might lie.Don’t forget, dear listener, we need your support!
