Episode 5 - Intro
-----

I discuss what I have been doing from late December 2024 to the end of February 2025, including watching Sakurajima volcano erupt, and an earthquake I felt in January. I discuss downloading sediment core data from NOAA and the attacks on the government science institutions in the United States. Finally, I have a discussion on DEI.

My recently published papers:

Episode 5 Deep Dive - Greenhouse Effect
-----

I introduce the Greenhouse Effect, and why even though the concentration of greenhouse gases are small, they play a large role in keeping the planet at a livable temperature.

-----
Episode 5 - More on the Greenhouse Effect
-----

I discuss the historical background on how the Greenhouse Effect was discovered, as well as how it came to be called the "greenhouse effect". I also discuss the greenhouse effect on Venus and Mars.

Episode 5 - Papers
-----

The first paper I go over is on determining paleo sea level from a beach ridge in Argentina. This research was part of the WARMCOASTS project, which I was part of. I briefly go through four other papers.
