Sea–level changes during the Miocene Icehouse Earth under high atmospheric CO2 (SealMICO2)



Fossil fuel consumption over the last century has resulted in a drastic increase in atmospheric carbon dioxide (ρC02) from pre-industrial levels of ~280 ppm, to over 400 ppm in September 2018  –  values not exceeded  for millions of years. According to IPPC the increased CO2 have impact not only on temperatures but also on the sea-level. It is estimated that by the end of this century the sea-level will have increased up to 100 cm. The low topography and long coastline makes Denmark especially sensitive to even minor sea-level changes.
