  "account": "Researchers studying coral heat tolerance in Hawaii found that different coral species and locations show varying degrees of resilience to rising ocean temperatures. Two coral species, Montipora capitata and Porites compressa, were tested in laboratory conditions simulating different thermal stress levels. Both species exhibited substantial tolerance, with a threshold for bleaching above NOAA's 4-degree heating week indicator. However, Porites compressa from cooler Ulupaʻu bay demonstrated significantly higher thermal tolerance compared to the same species from warmer Kāneʻohe Bay and Montipora capitata from either location. This suggests that local environmental conditions play a crucial role in shaping coral heat tolerance.",
  "summary": "As ocean temperatures rise, corals' ability to withstand and adapt to heat stress is critical for the future of coral reefs. Many reef-building corals already live near their upper thermal limits, making them vulnerable to bleaching and, with prolonged stress, mortality.",
