The ocean is upside down. Heat could turn seas from carbon sinks to emitters

Researchers fear that if that happens, the Earth will face climate change tipping points.

For the past few decades, scientists have focused on understanding how global warming and climate change will affect our planet. PSYS.org writes in a new study that scientists believe rising temperatures may be causing the ocean to transform from a pool of carbon dioxide to a producer.

Mixotrophic microbes are versatile organisms that can efficiently switch between photosynthesis (taking in carbon dioxide) like plants and feeding (releasing carbon dioxide) like animals. These organisms are widely distributed worldwide and are typically found in freshwater and marine environments. Studies show that they represent the majority of marine plankton.

In the study, scientists from Duke University and the University of California at Santa Barbara developed a computer simulation that simulates how myxotrophic microbes obtain energy in response to a warming planet. The researchers found that under warming conditions, these microbes turned from carbon sinks to carbon producers.

The study’s results show that as the planet warms, these large microbial communities may shift and start working in the opposite direction: from a net cooling effect to a net warming effect. Lead author of the study, Dr. According to Daniel Weczynski, the model showed that mixotrophic microbes actually play a more important role in the planet’s ecosystem and have a more significant impact on Earth’s climate changes than previously thought.

Co-author of the study, Dr. According to Holly Moeller, these microbes are essentially the keys to tackling or worsening the warming crisis. Despite being extremely small in size, their impact on the planet’s climate is truly impressive.

The researchers’ model also showed that mixotrophic microbial populations fluctuate greatly before switching to carbon dioxide production. Researchers believe it could be used as an indicator of devastating results.
