Climate Underground Podcast

Did you know that petroleum is as natural as water? That radioactivity keeps our planet warm? That Earth is still in what’s called an ice-house state? These are stories from Climate Underground, a podcast hosted by scientist, author, journalist, and professor Robert Thorson that examines our current climate crisis from an earthly perspective. Learning more about the Earth and its geological history has helped his students cope with climate confusion, misinformation, and exaggeration. All episodes are read from written scripts that are sourced from the scientific and secondary literature. These scripts are in the process of being reviewed for listenability and accuracy by students and scientific colleagues. Thumbnail image from NASA.

Episode 24 - Common Language

Tuesday Jun 14, 2022

Tuesday Jun 14, 2022

Miscommunication occurs when the words World, Planet, Globe, Earth, and Nature are used interchangeably as synonyms.  To effectively  deal with the climate crisis, we must speak the same language. (Note: In this version, I mis-stated "Where in the World is Carmen San Diego" for Where's Waldo. I'll fix this in the next version.)

Episode 23 - Climate Future

Tuesday Jun 14, 2022

Tuesday Jun 14, 2022

Though rigorously scientific climate models can help us predict the climate future, they cannot take into account the unpredictability of human beings.

Episode 22 - Edge of the Sea

Tuesday Jun 14, 2022

Tuesday Jun 14, 2022

The apparently stability of the edge of the sea is an illusion created by the human propensity for short-term thinking. Within the Cenozoic Era, mean global sea level has continuously risen and fallen between +70 meters and -130 meters.

Episode 21 - End of Ice

Saturday Jun 11, 2022

Saturday Jun 11, 2022

Owing to procrastination by the energy gulping cultures of developed nations, by the desire of developing nations to reach the same standard, and by a campaign of denial and misinformation by fossil fuel companies, humanity has baked into the climate system enough carbon to drive Earth out of its current icehouse state.

Episode 20 - Chameleon Earth

Saturday Jun 11, 2022

Saturday Jun 11, 2022

Going green has become a cultural meme that preferences one color of nature over another, preferences terrestrial ecologists above other natural scientists, and misrepresents the bulk Earth history.

Episode 18 - Cosmic Climates

Thursday Jun 09, 2022

Thursday Jun 09, 2022

When defined more broadly, Earth's climate also includes changes in radiation from the sun, pulses of radiation from other stars, changes in Earth's magnetic field, and changes in the flux of extraterrestrial dust and asteroids coming our way.

The great singularities of organic evolution reveal that life has always been in search of more concentrated forms of energy. Humanity's current obsession with fossil fuels follows a trend dating back to the origin of life.

Earth's average surface temperature has been kept within a fairly narrow range owing to a stabilizing, feedback loop in which a rise in CO2 increases the rate at which it is removed by rock weathering

Episode 15 - Vulcan Exhales

Tuesday Jun 07, 2022

Tuesday Jun 07, 2022

The carbon in Earth's underground reservoirs is returned to its atmosphere by the release of volcanic gasses at a rate that varies greatly. Without these exhalations, Earth would have long since frozen over.
