Climate Change not Dredging will effect the Great Barrier Reef

Leave a comment

Climate change is predicted to affect tropical marine systems in the following ways:

  • Warmer sea surface temperatures will increase the risk of heat stress events and mass coral bleaching.
  • Tropical cyclones are likely to be more intense, resulting in physical destruction and weakening of the reef structure.
  • Extreme rainfall events will increase, with larger amounts of low-salinity freshwater and sediment extending further out from the coast.
  • Sea levels will gradually rise, affecting coastal erosion, the magnitude of storm surges and the area available for shallow water marine organisms.
  • Ocean circulation and upwelling patterns will change.
