Podcasts about chemical weathering

On this week's show: When deer are scarce these wolves turn to sea otters, and chemical weathering of silicates acts as a geological thermostat First up on this week's show we have a story about a group of Alaskan wolves that has switched to eating sea otters as deer populations have dwindled. Science journalist Jack Tamisiea tells host Sarah Crespi about some of the recently published work on this diet shift, and wildlife biologist Gretchen Roffler weighs in on the conditions on the island where this is happening. Also on this week's show: Chemical weathering and the global carbon cycle. Sarah speaks with Susan Brantley, Evan Pugh university professor in the Earth and Environmental Systems Institute and Department of Geosciences at Pennsylvania State University, about how weathering of silicates in rocks pulls carbon dioxide from the atmosphere. They talk about how this temperature-sensitive process could increase as Earth warms, as well as the potential and limitations of this effect on the global carbon budget.   Take the podcast audience survey here.

This episode of the podcast breaks down the topic of Chemical Weathering into 3 simple sections. Chemical Weathering is discussed under the sections of: - Carbonation - Hydrolysis  - Exam Breakdown

A look at the geological history of Tibet and the Raymo Ruddiman hypothesis; that chemical weathering increased as the temperature dropped due to the rise in the plateau. Raymo and Ruddiman believed that the uplift of the Himalayas caused global cooling.

The importance of strontium isotopes in chemical weathering, a comparison of two models to assess the validity of the Raymo-Ruddiman hypothesis.

A look at Berner's model of the Carbon cycle and how it provided a basis for further research and experimentation into climate change by Maureen Raymo of MIT.

Transcript -- Is there really a link between the uplift of Tibet and climate change? Investigating when the change from building a plateau to destroying a plateau took place.
