When we think about climate change, we think about the changes that we can see on the territorial environment. However, the changes are also happening in the underwater environment. The article shows synergistic effects of temperature and light on seaweed and its epibacterial community. The research team took Taonia atomaria, a seaweed speice to check the global warming effects on the underwater plants and its microbes. The experiment was designed to check the synergistic effect of temperature and irradiance on the seaweed microbes for 14 days. As we can see in the figure, the middle part with ambient temperature and irradiance has the most microbes. The microbes’ environment provides protection, growth benefits for, and other essential functions of the plant. When the temperature and irradiance gets high the microbes' environment would not be able to stay with seaweed, the result of that would eventually kill the seaweed. Based on the research article, global warming with higher temperature and high irradiation would provide an immoblie environment for microbes on underwater plants. The plants would not survive without the microbes. The microbiome is not visible in our eyes, but it has significant functions on plants and animals; therefore, we have to look over the changes in microbiome from global warming.
