The report says that sea-level rise from Cape Hatteras, North Carolina to Boston, Massachusetts (a 600-mile expanse of coastal zone called the “hotspot” by scientists) has grown 2-3.7 millimeters per year since 1990. For comparison, scientists say that the global growth rate over the same time frame was 0.6 -1.0 millimeter per year.
The report warns that if global temperatures continue to increase, rates of sea level rise along the East Coast are likely to continue growing. Scientists say this prediction is based on data and analyses that are detailed in the report.
Good thinking. Anomalous local effects are caused by global warming.
Scientists say that global sea level will not increase at the same rate at every location, even though calculations show that it is likely to rise approximately two-to-three feet or more by the end of the 21st century. Sea level rise can vary both regionally and locally due to deviations in land movements, strength of ocean currents, water temperatures and other factors.
Eighty eight years left in the century, and a global growth rate of 0.6 to 1.0 mm per year. According to the government, that works out to two or three feet (600 to 900 mm.)
