The final installment in the CE series on sea level rise. Introduction Global mean sea level GMSL has increased by about 8—9 inches sincewith about 3 inches occurring since As discussed in Part VIscientists expect that GMSL will continue to rise well beyond the 21st century because of global warming that has already occurred and warming that is yet to occur.
The recent NOAA Report Global and Regional Sea Level Rise Scenarios for the United States has stated that even the relatively small increases in sea level over the last several decades have been associated greater storm impacts at many places along the U.
Further, the frequency of intermittent flooding associated with unusually high tides has increased rapidly in response to increases in local sea level, becoming a recurrent and disruptive problem.
Millions of people in the U.
Rising seas will dramatically increase the vulnerability of this growing population, along with critical infrastructure related to transportation, energy, trade, military readiness, and coastal ecosystems and the supporting services they provide.
It has been estimated in the NOAA report that 35 inches of sea level rise would permanently inundate areas currently home to 2 million Americans. This essay addresses the U. Apart from the issue of the extent to which global mean sea level rise can be attributed to human caused warming, this essay provides regional and local contexts for sea level rise against the broader context of global sea level rise.
The analysis includes a focus on: Mississippi delta region Cities: San Francisco, New York, Miami 2. Chapter 18 includes an assessment of the challenges of attributing any of these impacts to human-caused global warming.
While it is likely that extreme sea levels have increased globally since the s, mainly as a result of mean sea level rise due in part to anthropogenic warming, local sea level trends are also influenced by factors such as regional variability in ocean and atmospheric circulation, subsidence, isostatic adjustment, coastal erosion, and coastal modification.
As a consequence, the detection of the impact of climate change in observed changes in relative sea level remains challenging. Subsidence rates may also be sensitive to the rates of oil and gas removal. Many large cities on deltas and coastal plains have subsided during the last years: Loads from massive buildings and other large structures can also increase sediment compaction and subsidence.
Owing to the multiple natural and anthropogenic stressors contributing to coastal erosion, confidence in detection of a climate change contribution to observed shoreline changes is very low, with the exception of polar regions. Natural drivers combined with over-extraction, pollution, mining, and erosion compound groundwater supply problems.
However, the primary drivers of widespread observed changes in those systems are human drivers other than climate change so that there is very low confidence in the detection of impacts related to climate change Section 5.
There is no question that local sea levels are increasing in some locations at rates that are causing damage in coastal regions. However attributing these changes to human caused global warming even if you assume that recent global sea level rise is caused entirely by greenhouse gas emissions is very challenging.sounds like a new dance if this were the 60's Chubby Checkers or the Shirelles could sing "Do the Wobble with Me" i can hear it now.
The limited recharge capability of the aquifer, due to impervious surfaces and the million liters per day (mld) of reported industrial pumpage early in the 20th Century was probably the cause for the saltwater intrusion and the persistence of the historical saltwater intrusion wedges over time.
Salt Water Intrusion and Salination By: Ryan Tallman University of Phoenix In this modern world we are faced with many different issues. Sometimes we forget that the majority of our earth is covered in oceans and freshwater.
Almost two thirds of the world’s population lives within . The Modeling of Salt Water Intrusion Essay - The Modeling of Salt Water Intrusion What is Salt Water Intrusion. Salt water intrusion, or encroachment, is defined by Freeze and Cherry () as the migration of salt water into fresh water aquifers under the influence of groundwater development.
modeling studies will likely use both inverse methods and bined use of these methods is salt water intrusion. Salt water intrusion is important because (1) ~70% of the earth’s pop- Important Observations and Parameters for a Salt Water Intrusion Model by W.
