Based on the most up to date understanding, Richard Alley explains the fascinating interplay between geologic and chemical forces and how that directly influences our atmosphere's greenhouse properties and thus controls what will thrive in Earth's biosphere.
There are so many folds within folds of complexity that a talk or two doesn't do the topic justice, so I'm going to continue focusing on Deep-time and the evolution of Earth's atmosphere. Here I present an excellent talk by Professor Alley, who earned his PhD in 1987. Since then he’s established himself as a giant in the field of ice core studies and Paleoclimatology, having written over 240 refereed scientific publications, along with countless articles, and by now probably hundreds of engaging talks sharing his ever growing understanding with the lay public.
This one was given at the National Academy of Sciences 152nd Annual Meeting and Symposium—Earths, Moons, Mars & Stars. Below the fold I include notes and post many of his slides to help you fully appreciate the Professor's story.

On 4.6 Billion Years of Earth’s Climate History: The Role of CO2

Professor Richard Alley:
“You will meet people who say, ‘we are just telling stories,’ and no we aren’t.
We actually will generate hypotheses, that lead to new measurements,
that lead to new samples, that are taken specifically for hypothesis testing.”
