Korean scientists from Incheon National University in Seoul evaluated how climate change affects marine bacteria and their greenhouse gas emissions. The study was published in the scientific journal magazine Marine Pollution Bulletin (MPB).
The world’s oceans absorb most of the carbon and heat emissions. Over time, this leads to warming, acidification and deoxygenation (decreased oxygen concentration) of the waters. In addition, the increase in anthropogenic nitrogen emissions has also affected prokaryotic microorganisms living in the seas and producing nitrous oxide (N).2O) and methane (CH4).
Using biogeochemical analysis and genome sequencing, the authors of the scientific study revealed how global warming affects the microbial community in the ocean and its role in regulating N cycles.2O and CH4.
The results showed that prokaryotes from SL to DL were closely associated with warming factors. In the long term, the fragile marine ecosystem could be adversely affected by increased nitrous oxide production and subsequent changes in water acidity, ultimately leading to increased emissions of methane, a potent greenhouse gas.
Experts noted that the results deviate from the currently assumed potential of prokaryotes and biogeochemical processes associated with climate change.
The research may impact future studies on marine ecosystems. Policies to combat ocean acidification and warming can help stabilize vital microbial communities and greenhouse gas cycles.
