Episode 2.8 is now available on #YouTube!

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.

This episode’s guest is Dr Anne Pasek, Canada Research Chair in Media, Culture, and Environment, and an Assistant Professor in the Department of Cultural Studies and the School of the Environment at Trent University. Dr Pasek is co-founder of the Low Carbon Research Methods Group, and she talks to Ariel all about what Low Carbon Research is (and can look like!), the “carbon footprint” of academic research, new innovative ways for research to respond to the climate crisis, the importance of zines, and even hosting her own solar server in her backyard!

We're releasing today another bonus clip from behind the Patreon paywall. This originally was produced by Christina as a bonus clip to follow the early release of S5E5; supporters on Patreon at the Companion tier and higher gain access to bonus content that is either excerpted from episodes or prompted by their content every other week. Here is the original description:

"I didn't have any extra clips from the interview with the organizers of The Solarpunk Conference. Instead, here's me (Christina) reading my contribution to The Solarpunk Conference Journal that was published after last year's conference.
Enjoy!

PS- you can catch videos of many of the presentations from the conference on The Solarpunk Conference's YouTube channel (including the presentation/panel that @arielkroon was a part of)."

Is there anything more solarpunk than public libraries? Serving at the heart of communities, they’re a place where anyone regardless of income, ability, race, class, or gender can go to read books, listen to music, use the internet, learn things, hear story hour, get out of the weather for a while, and ask librarians for information on just about anything, including what organizations to turn to for additional support in your life or endeavor.

In Episode 2 of Season 2 of Solarpunk Presents, Christina talks to Don Gardner, a librarian for many years for the Salinas Public Libraries in Monterey County, California. Hear about how people rescued the library after the city council tried to close it down to save money, about what libraries can do for you and your community, and about what you can do for your local library.
