rising sea level

Extreme storms and rising sea levels will threaten the existence of coastal cities worldwide, unless preventative action is undertaken.

This is complicated by the fact that sea level around the world at any instant is not the same.

When you ask yourself what the biggest unanswered scientific questions are, “how did sea levels change over the past 100 years?” is unlikely to appear at the top of your list.

A matter of inches might help solve a riddle scientists have been working on for years: why rising ocean levels don’t match ice melt.

A study of almost 20 years’ worth of satellite images shows Antarctic sea levels are on the rise as ice shelves continue to melt.
