Ocean Acidity Hits Critical Threshold: A Dire Warning for Marine Life
The world’s oceans have crossed a critical threshold for marine life for the first time, primarily due to the burning of fossil fuels. This transgression makes ocean acidity the seventh of nine planetary boundaries to be breached, signaling a need for renewed global effort to curb human-driven pressures. The report highlights that increased ocean acidity has led to a 30-40% increase since the industrial era and is threatening cold-water corals, tropical reefs, and Arctic marine life. Scientists are particularly concerned about the weakening of the ocean’s role as a heat absorber and its ability to sequester carbon dioxide. However, the report emphasizes that good policies and international cooperation can help to reverse the trend and heal the planet.
