Ocean Warming Puts Earth Oxygen Supply at Risk, Study Finds
A new study has revealed that ocean warming poses a significant threat to Prochlorococcus a tiny marine microbe responsible for producing nearly a third of the Earth's oxygen. Contrary to previous assumptions that this heat-loving organism would thrive in warming oceans, the research shows that rising temperatures are causing its growth to slow, with potentially dire consequences for the planet's food webs and atmosphere.
A Critical Microbe Under Threat
Prochlorococcus is a microscopic cyanobacterium and is considered the most abundant photosynthetic organism on Earth. It inhabits over 75% of the sunlit surface waters, particularly in the tropics, where it forms the foundational base of many marine food webs.
However research led by oceanographer François Ribalet of the University...
