Global sea-levels could rise by about 30cm by the end of this century if current trends continue, a study warns.

The research, published in the journal Geophysical Research Letters, used data from tide gauges around the world.
Floods and surges. Melting ice on Antarctica is a cause of sea level riseIf the acceleration continues at the current rate, the scientists warn that sea levels could rise during this century by between 28 and 34cm.
Dr John Church, a scientist with the Commonwealth Scientific and Industrial Research Organisation based in Tasmania and an author of the study, said that higher sea levels could have grave effects on some areas.
