Connor Stedman: Carbon Farming

Sequestering atmospheric carbon through natural means
Monday, October 9, 2017, 5:10 PM

Climate change remains a hotly debated topic. But a scientific fact not up for dispute is the pronounced spike in the concentration of carbon dioxide in the Earth's atmosphere over the past two centuries.

There's a building urgency to find solutions that can manage/reverse that spike -- a process known as carbon sequestration. But how to do that on a planetary scale? It's a massive predicament. And most of the 'solutions' being proposed are technologically unproven, prohibitively costly and/or completely impractical.

Enter carbon farming. It uses nature-based farming practices to park gigatons of carbon in the soil, rebuild soil health and complexity, and revitalize the nutrient density of the foods that we eat. » Read more

Mark Cochrane: Climate Change, Revisited

The latest on what science has to say
Sunday, November 27, 2016, 5:27 PM

Mark Cochrane, Professor and Senior Research Scientist at the Geospatial Science Center of Excellence at South Dakota State University, returns to the podcast after a year and a half to update us on what the latest science has to tell us on the (often controversial) topic of climate change.

Mark has been researching the climate for over 20 years, and among his many other accomplishments, moderates what we believe to be the most level-headed, open-minded and data-centric discussion forum on climate change available on the Internet today.

In this week's podcast, Mark updates us on the latest empirical data, separates out what science can and cannot prove today regarding climate change, and provides clarity into closely-related but less well-understood issues, such as ocean acidification. » Read more

The Environment: Increasing Waste - Crash Course Chapter 24

We are killing the ecosystems we depend on
Friday, December 5, 2014, 7:54 PM

Following up on the previous chapter focusing on human-caused resource depletion, the other disheartening part of the story of the environment concerns the things we humans put back into it, and the impact they have on the ecosystems that support all of life -- ours included.

Like the economy, ecosystems are complex systems.  That means that they owe their complexity and order to energy flows and, most importantly, they are inherently unpredictable.  How they will respond to the change by a thousand rapid insults is unknown and literally unknowable. » Read more
