This paper discusses the changing pattern of climatic conditions (temperature and rainfall), reviewing sea level rise scenarios and its Along the coast of the Bay of Bengal, a rising sea level is worsening the problems. Climate experts predict that by 2050, rising sea levels will submerge some 17 percent of the nation’s land and displace about 20 million people. Dhaka, Bangladesh: Dhaka is sinking at a rate of 1.4 centimeters (approximately 0.55 inches) per year, and sea level rise in the Bay of Bengal is apparently around 10 times the global average. With changes in sea level, these scenarios have worsened—the duration in which land is flooded becoming less temporary than was before.

"Mitigation" is a strategy by which steps are taken to stop or slow down sea level rise. watersheds watersheds. Added to the threat of sea-level rise … Warming of 4 °C (7.2 °F) is close to our current path, would represent a breakdown in efforts, and corresponds to 8.9 m (29.2 ft) of locked-in global sea level rise. And for Manhattan, Florida and Bangladesh in particular, issues go above and beyond sea level rise. It also corresponds, in this analysis, to 4.7 meters (15.4 feet) of global sea level rise locked in to someday take place. And sea level rise threatens everyone living in coastal areas, delta regions, and small-island countries. According to Banglapedia, national encyclopedia of Bangladesh: “The rise of global sea level by the end of AD 2050 would mean that there is a high risk of coastal inundation by sea water. He predicted that seas in Bangladesh could rise as much as 13 feet by 2100, four times the global average. Coastal communities are aware of the threat from climate change, as its impacts hit them on an annual basis. Select tide gauges within the U.S. where at least 30 years of hourly water level data are available also give flood risk projections which integrate sea level rise, based on methods described in more recent research (Tebaldi et al. A simple three-part diagram from UNEP GRID Vital Water Graphics showing how global warming could impact coastlines and populated areas of Bangladesh with a 1 and 1.5 meter sea level rise relative to the current coastline. This is … Sea level rise will pose unique challenges because of the resultant saline contamination and, eventually, permanent loss of habitable lands. Government data shows sea level rise of about 5.7 millimeters per year at Char Changa station in Hatiya, and 3.4 millimeters per year at Hiron Point in the Sundarbans.

To find the source of this threat it is necessary to focus on global warming caused by climate change, which causes sea level rise in three different ways: The first is the thermal expansion: water, when heated by temperature rise, tends to expand, ie, oceans take up more space. But if sea levels rise 30cm, floodwaters could slosh around the palazzi for several weeks. watersheds watersheds.

Sea level rise will cause transport) Settlements: displacement of inhabitants and loss of livelihood Coastal management Industry and energy Disaster response & recovery plans As humanity pollutes the atmosphere with greenhouse gases, the planet warms. The change in sea levels is linked to three primary factors, all induced by ongoing global climate change: Thermal expansion: When water heats up, it expands.About half of the sea-level rise … Because of the slow process of heat diffusion in water, the world’s oceans are likely to continue to warm for several centuries in response to increases in greenhouse concentrations that have taken place so far. Sea levels in Bangladesh are predicted to rise by up to 0.30 metres by 2050, resulting in the displacement of 0.9 million people, and by up to 0.74 metres by 2100, resulting in the displacement of 2.1 million people. Bangladesh is likely to be one of the most vulnerable countries in the world to climate change and sea level rise. By some estimates, rising sea levels could permanently “submerge almost 20 percent of the country and displace more than 30 million people” while wreaking havoc on local ecosystems. Its coastline on the Bay of Bengal measures about 580 kilometers (360 miles), with a large portion consumed by the Ganges river delta.
