No Compelling Evidence That Recent Sea Level Rise Is Abnormal

      Mean global sea level has risen at a slow creep for more than 150 years; since 1900, global mean sea level has risen about 7-8 inches. The implications of the highest values of projected sea-level rise under future climate change scenarios are profound, with far reaching socioeconomic and environmental implications. However, these projections are regarded as deeply uncertain and the highest of these projections strain credulity.
      Recent research has concluded that there is no consistent or compelling evidence that recent rates of sea level rise are higher or abnormal in the context of the historical records back to the 19th century that are available across Europe.
        In many of the most vulnerable coastal locations, the dominant causes of local sea level rise are natural oceanic and geologic processes and land use practices. Land use and engineering in the major coastal cities have brought on many of the worst problems, notably land-filling in coastal wetland areas and groundwater extraction.
       Local sea level in many regions will continue to rise in the 21st century – independent of global climate change. The appropriate range of sea level rise scenarios to consider for 2100 is 8 inches to 5 feet. 
      Values of sea level rise are contingent on the climate models predicting the correct amount of temperature increase. However, there are numerous reasons to think that the climate models are predicting too much warming for the 21st century
