2. Coral Bleaching Events Becoming More Frequent

Context

• The seventh Status of Coral Reefs of the World report released by the Global Coral Reef Monitoring Network (GCRMN) highlights a sharp reduction in the recovery time available to coral reefs between successive bleaching events.
• Increasingly frequent episodes of severe marine heat stress are leaving corals with less time to recover, increasing the risk of long-term reef degradation.

Major Highlights

• Since 2010, major disturbances have occurred approximately every four to six years in many regions, compared with roughly once every decade during the earlier period.
• Global hard coral cover has declined by an estimated 5% compared with the 1980–2009 reference period.
• In 2024, more than 40% of coral reefs experienced heat stress severe enough to create a significant risk of bleaching and coral mortality.
• The report cautions that increasingly frequent marine heatwaves, driven by climate change and intensified by local environmental pressures, could push coral ecosystems towards persistent decline.
• Without substantial reductions in greenhouse-gas emissions, global warming could exceed 2°C, while marine heatwaves could become more frequent and intense, placing additional pressure on coral reefs.

What are Corals?

• Corals are marine invertebrates belonging to the phylum Cnidaria.
• Coral colonies consist of numerous small, soft-bodied organisms called polyps.
  • These polyps secrete a hard, chalk-like calcium carbonate skeleton around themselves.
  • Over long periods, millions of polyps collectively form the large carbonate structures known as coral reefs.
• Appearance:
  • Corals may occur in colours ranging from red and purple to blue, although brown and green shades are particularly common.
  • Their vibrant colours are largely associated with microscopic symbiotic algae known as zooxanthellae.
• Types of Coral Reefs:
  • Fringing reefs: Develop directly along coastlines.
  • Barrier reefs: Occur farther from the coastline, separated from land by a lagoon or deeper water.
  • Atolls: Circular or ring-shaped reefs generally associated with submerged or sinking volcanic islands.
• Coral Reefs in India:
  • Gulf of Kutch;
  • Gulf of Mannar;
  • Andaman and Nicobar Islands;
  • Lakshadweep Islands; and
  • Malvan coast.
• Significance:
  • Coral reefs provide food, shelter, breeding grounds and nursery habitats for a large proportion of marine life.
  • They act as important refuges for marine biodiversity.
  • Coral ecosystems also support the livelihoods, food security and recreational activities of more than one billion people living in coastal regions globally.

Coral Bleaching

• Coral bleaching occurs when corals expel the microscopic symbiotic algae living within their tissues, generally in response to environmental stress, particularly elevated ocean temperatures.
• The loss of these algae causes corals to lose their characteristic colour and appear pale or white.
• Since the algae provide important nutritional benefits to corals, prolonged bleaching can leave them vulnerable to:
  • Starvation; and
  • Disease.
• Bleaching does not necessarily mean that the coral is dead.
  • If ocean temperatures fall and environmental conditions return towards normal, corals may regain their symbiotic algae and gradually recover.

Reasons for Coral Bleaching

• Marine Heatwaves and Climate Change:
  • Rising sea-surface temperatures disrupt the symbiotic relationship between corals and their algae.
  • Prolonged heat stress can result in widespread bleaching and, in severe cases, coral mortality.
• Ocean Acidification:
  • Increasing atmospheric CO₂ is absorbed by oceans, lowering seawater pH.
  • This makes it more difficult for corals to build and maintain their calcium carbonate skeletons.
• Pollution:
  • Runoff carrying fertilisers, pesticides and heavy metals such as lead can damage coral health and reduce reef resilience.
• Physical Disturbance:
  • Coastal development, destructive or unsustainable fishing practices, sedimentation and coral mining can physically damage reefs or cover them with sediments.
• Overfishing:
  • Declining populations of herbivorous fish can allow algae to proliferate on reefs.
  • Excessive algal growth can further weaken already stressed coral ecosystems.

Can Corals Recover from Bleaching?

• Yes, corals can recover from bleaching, provided that the environmental stress is reduced and ocean temperatures return to suitable levels.
• When conditions improve, symbiotic algae can return to coral tissues, allowing the corals to gradually restore their colour and physiological health.
• However, increasingly frequent bleaching events shorten the recovery window and can make repeated stress increasingly damaging to coral ecosystems.
