In episode two we drill into the soil profile to learn about soil layers in northern landscapes. This shows us how deep permafrost is, and the impacts to people as the soil profile changes and permafrost thaws.

topics and purpose: soil layers in northern regions are impacted by global warming; temperature records and increases, impacts of permafrost thaw on local and global levels

terms defined: soil core & soil profile; active layer, transition zone, permafrost layer

As global temperatures increase due to anthropogenic climate change, a myriad of impacts result for people and the planet. In this podcast, we share the ramifications of cryosphere change (melting/thawing water from solid ice) as the planet warms.

In the first episode of season two, we introduce the topic of permafrost thaw, which will be explored throughout this season. In northern latitudes and at colder reaches of Earth, deep soil layers historically remained frozen year-round. Now warmer temperatures are causing this soil to thaw, and the repercussions are significant on local and global levels.

Permafrost Pathways helps us dig into the topic and science of permafrost. Artist Nikki Lindt introduces us to her work which captures sounds of thawing.

topics and purpose: an introduction to permafrost, which is actively thawing in northern latitudes – Nikki Lindt shares her related audio recordings and experiences; local and global impacts of permafrost thaw

terms defined: cryosphere, permafrost; continuous and discontinuous permafrost, thermokarst slump, positive feedback loop

notes: We recommend using over-the-ear headphones or speakers when listening to this episode due to some subtle, low frequency field audio shared. More of Nikki Lindt’s work with the Underground Sound Project can be found here. Learn more about the Permafrost Pathways Program, part of the Woodwell Climate Research Center, here.

In the last episode of the season, we dissect Robert Frost's 1920 poem, Fire and Ice, over a tent poetry session. This involves grappling with climate anxiety, and recognizing the role of personal behaviors in perpetuating the climate crisis.
