Sea level change research has become crucial to the debate of climate change. This article attempts to identify factors that have been linked to sea level changes across the world, the change measurements and the possible consequences with special reference to the Indian Ocean.
Sea level is a very sensitive index of climate change and variability. As the oceans warm in response to global warming, sea waters expand raising sea levels; mountain glaciers melt in response to increasing air temperature, and fresh water mass input to the oceans increase, again raising the sea level; and, ice mass loss from the ice sheets, also results in sea level rise. In addition, redistribution of heat inside the oceans by the ocean circulation causes regional variability in...
