====== Sea level rises ======

Climate change, along with the associated ice-shelf melting, contributes to sea level rise. However, the calculations linking the temperature records with ice melt leave an unexplained 12 cm/century rise in the actual levels - as measured around the world by tide gauges (and recently by satellite radar). Put another way, the levels are rising 3 to 4 times faster than can currently be explained.

This anomaly, called the  [[https://www.nature.com/nature/journal/v428/n6981/full/nature02309.html|Attribution Problem]]  by geo-scientists, has been the subject of intense debate. There are various theories revolving around the general observation that : //"either the tide gauge estimates are too high, as has been suggested recently, or one (or both) of the mass and volume estimates is too low."//

A new theory (2015) suggests the idea that the anomalies may be caused by changes in the size of the Earth itself.
