Podcast 134 - Training Fish in the Hyperbolic Time Chamber

The gang discusses two papers that look how the environmental stresses caused from warming temperatures can affect fish. Specifically, we look at a paleontological study focusing on the Permian and Late-Triassic extinctions (often considered to be runaway greenhouse scenarios) as well as a modern study looking at the impact modern global climate change might have on goby fishes. Also, James offers to train Amanda, Curt starts a brand new business venture, and Amanda decides to pump pure sugar into her veins. Also, apologies for the fact that James has finally finished Dragon Ball Z and naturally keeps finding patterns.

Up-Goer Five (Curt Edition):

The friends talk about papers that show how changes around the world can cause animals that move through the water and breathe water to die. The first paper talks about animals that move through the water and breathe water that died a very long time ago, during a time when nearly everything died. During this time when nearly everything died a lot of really bad things happened, like the world got a lot warmer and the water became hard to breathe. During this time, it appears that some of the animals that move through the water and breathe water actually did really well, while almost all of the other animals living in the water did really bad. The animals that did really well would eventually become a family we see today that has big teeth, eats a lot, and has soft parts inside. The paper says that maybe the way these animals lived help them get through this bad time when nearly everything died.

The second paper looks at animals that move through water and breathe water which are around today, and how these animals are being hurt by how much warmer it has been getting each year. They took some of these animals and raised them for a year in a warm home. Then they took the animals and made it warmer and saw if the animals were happy. When the animals got sad, they stopped and looked at how warm it got. They found that lots of things changed how warm the animals could get before they got sad. Animals that were brother and sister got sad in the same kinds of ways. Also, how warm the animals got in the year of training changed when the animals got sad. They showed that there were a lot of things to consider when we want to know how warm these animals can get before they become sad.
