Deep oceans are now more acidic than ever, threatening marine life, coastal economies, and Earth’s balance. With nearly two-thirds of waters affected, urgent action is needed to protect our planet’s vital ecosystems before it’s too late.
——————-
Overview:
• The deep oceans have crossed a critical acidity threshold, threatening their ability to supply food and oxygen to surface ecosystems, posing a significant risk to marine life and coastal economies.
• Nearly two-thirds of waters below 200 meters and about half of shallower waters have exceeded safe acidity levels, with deeper waters off western North America experiencing some of the most drastic changes.
• The primary cause of increased ocean acidity is the ongoing global burning of fossil fuels, which releases carbon dioxide that dissolves into seawater, making it more acidic and less hospitable to key marine species like corals and shellfish.
• Crossing the calcium carbonate threshold signifies that the oceans may have already surpassed seven of nine planetary boundaries vital for maintaining Earth’s ecosystem stability, leading to habitat loss for numerous marine species.
• Elevated ocean acidity and warming reduce the ocean’s capacity to absorb further CO2 and heat, threaten its role in oxygen production, and jeopardize biodiversity, with significant ecological and economic consequences.
