The findings, published this week in the Proceedings of the National Academy of Sciences show that during the past 6000 years, sea levels are unlikely to have fluctuated by more than 20 centimetres over 200 years. Compared against this background signal the recent rise of about 20 centimetres in 100 years recorded by tide gauges is anomalous, says co-author Professor Kurt Lambeck, of the Research School of Earth Sciences and the Australian National University. We see no evidence in the geological record from about 6000 years ago to 100-150 years that resembles the rise that we see in the last 100 years. Lambeck and colleagues also confirm that natural fluctuations in sea level over the past 6000 years have been smaller than what some have suggested. - Anna Salleh, ABC Science
