World Heritage properties are important to all people and have a universal value that transcends national boundaries. Nearly one-fifth of world cultural heritage sites would be affected by global warming as the ice sheets melt and warming ocean expands.
From Skeptical Science, we are given that with rise in global warming and with the added factor of the ice loss from Greenland and Antarctica accelerating, the estimated sea level rise by 2100 is between 75cm to 2 meters. If the current trend of sea level rise continues, temperatures will increase 3C over the next 2000 years, thus leading to the Opera House being fully immersed in water. (taken from Gizmodo)
With the given information, we can attempt to calculate the level in which the sea level will reach per year. without the acceleration of the ice loss taken into consideration, the sail on the furthest left should be immersed by 4500.
