In this episode we will examine how the atmosphere is made up, and what changes occur when there are drastic climatic shifts. We will also look at the how greenhouse gases affect the atmosphere and the interrelationship between the atmosphere, greenhouse gases and the oceans. We will examine chemical composition of the oceans, ocean currents and how important they are to climate stability, as well as the water cycle.

In this episode we will look at the formation of supercontinents, like Pangaea and their break up all have had an effect on climate. Moreover, volcanoes, and a multitude of super-volcanoes (known as traps), have related millions of tonnes of CO2 into the early atmosphere and drastically changed the climate. Today we sometimes get glimpses of these events may have been like, such as the eruption of Mount Pinatubo in the Phillipines in the early 1990s.

Did you know that the Earth's orbit around the our Sun and changes in our planet's tilt range create cycles of climate change? This episode we will delve into the Milanovitch cycles, and other extra-terrestrial factors that can affect our climate over time. The episode will include how solar flares and cosmic rays can alter our climate over short and long term, and the how the Earth repells the deadliest of these.
