Oceans Declared a ‘Ticking Time Bomb,’ Warns New Study

Fast Summary:

• A new study by researchers at Plymouth Marine Laboratory, NOAA, and Oregon State University reveals oceans have exceeded the “planetary boundary” for acidification since 2018.
• Ocean acidification is described as a “ticking time bomb,” with meaningful threats to marine ecosystems and coastal economies.
• At 200 meters below the surface, data shows that 60% of global oceans are already beyond the safe limit for acidification.
• Other issues linked to climate change include sunlight depletion in 21% of ocean areas and warming rates that are 400% faster than four decades ago.
• Researchers emphasize reducing CO2 emissions as crucial to reversing ocean acidification.

Indian Opinion Analysis:

The findings highlight growing challenges for global environmental sustainability. For India, which has a vast coastline extending over 7,500 kilometers and vibrant marine biodiversity supporting millions dependent on fishing industries, ocean acidification brings serious risks. Healthy marine ecosystems are pivotal not only for biodiversity but also for food security in coastal areas. Further exacerbation may destabilize economic activities tied to fisheries or tourism along India’s coasts.

This underscores India’s role in international climate action initiatives like COP summits while reinforcing the necessity of domestic efforts such as renewable energy adoption and CO2 emission controls. The country’s proactive measures could mitigate harm to its oceans while bolstering its leadership position in global conversations on environmental preservation.
