Study Uncovers Two Metres Increase in Sea Level In Coming Century

Sea levels next century

Study has uncovered that there will be two metres increase in sea level in next century. The United Nations' Intergovernmental Panel on Climate Change (IPCC) said its 2013 Fifth Assessment Report that under current emissions trajectories -- a "business-as-usual" scenario known as RCP8.5 -- would likely rise by up to one metre by 2100.

In this regard, the global sea level geometrical increase by two metres will displace tens of millions of people by the end of the century, according to new projections that double the UN's benchmark estimates.

Further more, the vast ice sheets of Greenland and Antarctica contain enough frozen water to lift the world's oceans dozens of metres. The expansion of water as oceans warm also contributes to sea level rise.

However, but predicting the rates at which they will melt as the planet heats is notoriously tricky.
That prediction has since been viewed as conservative, as the levels of planet-warming greenhouse gas emissions continue to rise year on year, and satellites showing accelerated rates of melt-off from massive ice sheets atop Antarctica and Greenland.
