A sea level rise of 200 meters would still leave us some dry land in the Netherlands - but only in the southernmost tip of the country.
A sea level rise of 200 meters would still leave us some dry land in the Netherlands - but only in the southernmost tip of the country. Until recently, scientists were dependent on information about past plate tectonics when reconstructing past global mean sea level. But now, a team of Dutch, British and American Earth scientists have developed a new method for determining historic global sea level where the influence of land ice is included. As a result, it has become possible to look back 540 million years. "It is the only reconstruction in the world of its kind that goes so far back in time. For the time being, the limit of what we can reconstruct has been reached." Determining changes in sea level in the geological past is vital for understanding the distribution of land and oceans and natural climate change before humans evolved. Since the 1970s, scientists have estimated changes in global mean sea level by studying sediments, for example in the North Sea.
