Such a change far outstrips current projections and could be catastrophic for vast swathes of humanity, a team at Australian National University concluded in a study.

During the last interglacial period, "sea levels rose at up to three metres per century, far exceeding the roughly 0.3-metre rise observed over the past 150 years," they said in a blog about their findings, published Wednesday in the journal Nature Communications.

Over the last million years, Earth has alternated between roughly 100,000-year-long cold periods -- ice ages -- and shorter, temperate spells such as the last 11,500 years, known as the Holocene.

Global warming could drive a much more dramatic increase in sea levels than current projections suggest, scientists say, citing a rise of 10 meters (33 feet) during Earth's last warming interlude more than 100,000 years ago.
