A new analysis has examined the effects of melting polar ice sheets and the subsequent rise in sea levels over the last three million years.
The paper summarizes 30 years of research into the relationships between melting ice sheets, fluctuating sea levels and the levels of carbon dioxide in the atmosphere.
Its most startling conclusion: sea levels have risen by 6 meters (20 feet) multiple times in the past, and this increase was prompted by a rise in global mean temperatures of only 1–2C.
