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

In Crash Course Chapter 18: The Environment, Chris Martenson explains how multiple essential resources are being depleted at ever faster rates. Our money system requires continual economic growth, but energy depletion will run headlong into dwindling resource returns to limit future growth options. Overpopulation will increase competition and demand for fossil fuel energy sources such as crude oil and coal, as well as for natural gas and sources of alternative energy.

In this chapter, Peak Coal, Peak Uranium, and copper extraction are explored as illustrations challenging long-held assumptions about the inevitable certainty of continued global economic expansion. This chapter makes it easy to understand why careful management of our natural resources will be necessary for our economic and environmental future.
