Summary:

This article explains that the World’s oceans are going to change color as a result of climate change. Researchers point out that the base of the food chain in the oceans is phytoplankton. With an increase in water temperature, the phytoplankton will die, resulting in an ocean that is not as green (as phytoplankton have green pigment from the chloroplasts). This article also explained that by using the color of the ocean one can deduce the population of phytoplankton, therefore getting more data on how global warming is affecting the world.

Connections

We have been learning in class the different properties of microorganisms. Right now we are learning how the metabolism works. By understanding this concept, I can use my knowledge to fully understand how an increase in temperature would affect the microorganism’s ability to acquire food and survive. Furthermore, we have been learning in class how different microorganisms can change the environment that they are in.

Critical Analysis

I found this story interesting because I liked the concept that you could tell the population of an organism, like phytoplankton, by looking at the color of the water. Although, I can see many variables in trying to actually test this idea. There are many things that can change the color of something, especially in the ocean, so I don’t see how they could do this. I think that this article did a fine job of relaying information to the general public so they could understand topics that they might not have any experience dealing with it. On the other hand, that means that this article most likely left out many concepts that the general public wouldn’t understand, but I would find interesting.

Question

What is the main reason why an increase in temperature of a few degrees would kill phytoplankton?
