They found a pattern of sea level change that was consistent with warming and cooling climate.
From 200BC to AD1,000, sealevels were relatively stable. Then during a 400-year warm climate period from the start of the 11th century, the levels rose by about half a millimetre a year.
This was followed by a second period of stable sea level associated with a cooler period, known as the Little Ice Age, which lasted until the late 19th century.
But there had been a dramatic change since the start of industrialisation and sharp increases in greenhouse gas emissions.
From the late 19th century onwards, sea levels had risen by an average of more than two millimetres a year, the steepest rate for 2,100 years. Read the full report here.
