Not exact matches

Prompt action is needed most in Asia and Africa where, today, large parts of the coastal population are already affected by storm surge flooding.

This relatively sudden rise of normal sea level occurs when storm winds and tides combine to transport large volumes of water to coastal areas.

And while countries like Myanmar will have the largest number of displaced peoples from climate change, even countries like the US are likely to see a surge in internally displaced people as coastal communities come face to face with sea level rise and more destructive storms.

Coastal states with large areas of low - lying land, including Louisiana, Florida, North Carolina, California, and South Carolina, are particularly vulnerable to rising seas and coastal storm surges.

Mid-latitude islands, such as islands in the Gulf of St. Lawrence and off the coast of Newfoundland (St. Pierre et Miquelon), are exposed to impacts from tropical, post-tropical, and extra-tropical storms that can produce storm - surge flooding, large waves, coastal erosion, and (in some winter storms) direct sea ice damage to infrastructure and property.

More - powerful storms can combine with even a modest rise in sea level in a dangerous synergy, allowing for ever larger storm surges that can flatten coastal communities.

Coastal marshes absorb and store large amounts of carbon dioxide from Earth's atmosphere; they help filter out pollution in coastal waters; provide habitat for wildlife; help protect coastlines from erosion and storm surge; and can store huge amounts of floodwater, reducing the threat of flooding in low - lying coastal areas.

With the late - summer ice edge located farther north than it used to be, storms produce larger waves and more coastal erosion.5 An additional contributing factor is that coastal bluffs that were «cemented» by ice - rich permafrost are beginning to thaw in response to warmer air and ocean waters, and are therefore more vulnerable to erosion.22 Standard defensive adaptation strategies to protect coastal communities from erosion, such as use of rock walls, sandbags, and riprap, have been largely unsuccessful.23 Several coastal communities are seeking to relocate to escape erosion that threatens infrastructure and services but, because of high costs and policy constraints on use of federal funds for community relocation, only one Alaskan village has begun to relocate (see also Ch.

There is new information that lack of sea ice causes storms to produce larger waves and more coastal erosion.5 An additional contributing factor is that coastal bluffs that were «cemented» by permafrost are beginning to thaw in response to warmer air and ocean waters, and are therefore more vulnerable to erosion.22 Standard defensive adaptation strategies to protect coastal communities from erosion such as use of rock walls, sandbags, and riprap have been largely unsuccessful.23 There remains considerable uncertainty, however, about the spatial patterns of future coastal erosion.

«If we cause large sea - level rise, that dominates future risks, but if we could prevent sea - level rise and just have the storm surge to worry about, our projections show little change in coastal risk from today during most years,» said Michael Mann, distinguished professor of meteorology and atmospheric science and director of Penn State's Earth System Science Centre, and one of the authors.

For example, rising sea level increases the likelihood that a storm surge will overtop a levee or damage other coastal infrastructure, such as coastal roads, sewage treatment plants, or gas lines — all with potentially large, expensive, and immediate consequences (Nordhaus, 2010).
