سیلاب ، زمین های باتلاقی را با بالا آمده ناگهانی رویه ی دریا ها ، در بر خواهد گرفت Most Coastal Wetlands Worldwide Could Disappear This Century



Under a rapid sea-level rise model most coastal marshes will be flooded

Many coastal wetlands worldwide — including several on the U.S. Atlantic coast — may be more sensitive than previously thought to climate change and sea-level rise projections for the 21st century.

U.S. Geological Survey scientists made this conclusion from an international research modeling effort published December 1, 2010 in the journal Geophysical Research Letters, a publication of the American Geophysical Union. Scientists identified conditions under which coastal wetlands could survive rising sea level.

Rapid / Slow Sea-Level Rise Scenarios


Using a rapid sea-level rise scenario, most coastal wetlands worldwide will disappear near the end of the 21st century. In contrast, under the slow sea-level rise projection, wetlands with low sediment availability and low tidal ranges are vulnerable and may drown. However, in the slow sea-level rise projection, wetlands with higher sediment availability would be more likely to survive.
