RT null T1 Sea-level Rise in the Indian Ocean Differs by Region and Low-lying Pacific Reef Islands can Grow or Shrink in Size Depending on Conditions - UNEP Global Environmental Alert Service (GEAS) December 2010 A1 United Nations Environment Programme, K1 climate change K1 Indian Ocean K1 rising sea level K1 sea level rise K1 Asia and the Pacific YR 2010 FD 2010-12 LK https://wedocs.unep.org/handle/20.500.11822/40851 UL https://wedocs.unep.org/handle/20.500.11822/40851 NO Over the past few decades, sea levels worldwide have risen because of three primary phenomena related to climate change: the expansion of warming oceans, the input of fresh water from melting ice sheets and the loss of ice mass from Greenland and Antarctica (see the Near Real-Time Environmental Event Alert on page 7) (Climate Institute 2010). Rising seas threaten millions of people who live in densely populated coastal areas and low-lying islands, so it is critical for risk management purposes to estimate and prepare for the impacts of future sea-level rise and to be aware of regional differences.
