A journey through the digestive system, beginning with the mouth and progressing through the esophagus, stomach, small intestine, and large intestine, we consider the structure and function of all key components of the gastrointestinal tract and their roles in facilitating the metabolism of our food. We also discuss the contribution of accessory organs, including the liver, gall bladder, and pancreas. We conclude by considering a few myths about digestion. Recommended pre-listening is Episode 25: Tissues, Organs and Systems.

Episode 137: The Digestive System

I discuss a variety of topics in both the natural and social sciences, exploring the many fascinating insights that the scientific method yields about the world around us.

Our climate change series concludes with a discussion of the various lines of evidence indicating that recent warming is the result of human-produced greenhouse gases, including greater warming at night, cooling of the stratosphere, and relative depletion of C14 in the atmosphere. We then consider the various expected impacts of climate change, including increased extreme weather events, acidification of the oceans, changes to crop yields, and affects on various ecosystems. We end with an analysis of the relative costs and benefits of mitigation, and discuss likjely climate projections for the remainder of the 21st century. Recommended pre-listening is Episode 143: Climate Modelling.

Episode 144: Anthropogenic Climate Change

An overview of climate models, beginning with a summary of the major types of models, and then a more detailed disussion of hte primitive equations and parameterised feedbacks that characterise the widely used Atmospheric General Circulation Models. We also discuss techniques for model validation and some evidence regarding the accuracy of various climate models. Recommended pre-listening is Episode 142: The Greenhouse Effect.

Episode 143: Climate Modelling

A detailed discussion of the greenhouse effect and its impact on Earth's climate. We begin with a discussion of Earth’s energy budget, the various greenhouse gases and their interactions with longwave radiation, and a summary of major sources of greenhouse gas emisions. We then examine the mechanisms of the greenhouse effect in more detail using the idealised greenhouse model and radiative transfer models. We conclude with an analysis of the sensitivity of Earth's climate to changes in greenhouse gas concentrations, and how this interacts with the atmospheric lapse rate. Recommended prelistening is Episode 141: Natural Climate Change.

Episode 142: The Greenhouse Effect

An overview of the natural mechanisms by which climate changes over time. Beginning with an introduction to the concepts of radiative forcing and climate sensitivity, we then discuss solar forcing, orbital changes, volcanic eruptions, and silicate weathering, covering how each process operates and the effects it has on Earth's climate over varying periods of time. Recommended pre-listening is Episode 140: A History of Earth's Climate.

Episode 141: Natural Climate Change

A journey through the history of Earth's changing climate, in which we explore how Earth's climate has fluctuated over the past billion years. After reviewing the various temperature proxies used to estimate past climactic conditions, we discuss the varying hothouse and icehouse periods of Earth's history, the onset of the Quarternay Ice Age, the current interglacial period, the anomoly of the Younger Dryas, the Medieval Warm Period and Little Ice Ages, and the rapid rise in temperatures during the twentieth century. Recommended pre-listening is Episode 90: Climate Systems.
