The Earth’s vast and interconnected oceanic realm, often hailed as the global life-support system, is undergoing transformative changes in response to the sweeping impacts of climate change. A groundbreaking study conducted by a team of researchers at Incheon National University delves into the nuanced relationship between climate change and marine microbes, shedding light on their pivotal role in the production of greenhouse gases, notably nitrous oxide (N2O) and methane (CH4). The findings, detailed in Volume 196 of Marine Pollution Bulletin on November 1, 2023, highlight the urgent need for a comprehensive understanding of the consequences of climate change on ocean ecosystems.
