Hidden Ocean Methane Threat Scientists Warn
The world’s oceans may be hiding a powerful new climate threat. In a groundbreaking scientific discovery, researchers have found that methane — one of the most potent greenhouse gases — is being produced directly in oxygen-rich waters of the open ocean. This unexpected source comes from microscopic marine organisms that thrive when nutrients become scarce. The finding has raised serious concerns among climate scientists because it may create a self-reinforcing warming cycle that accelerates global climate change. The Hidden Methane Source in the Open Ocean For decades, scientists believed that methane was mainly produced in environments lacking oxygen, such as wetlands, deep-sea sediments, and swamps. However, a new study published in the Proceedings of the National Academy of Sciences has solved a long-standing mystery: why surface ocean waters, despite being rich in oxygen, still release methane into the atmosphere. The answer lies in marine microbes. Researchers discover...
