Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean levels continue to rise long after warming of the atmosphere levels off. "Even though the oceans are absorbing a good deal of the total global warming, the atmosphere is warming faster than the oceans," McKay adds. "Moreover, ocean warming is lagging behind the warming of the atmosphere. The melting of large polar ice sheets lags even farther behind." The authors cautioned that past evidence is not a prediction of the future, mostly because global temperatures during the Last Interglacial were driven by changes in the Earth's orbit around the sun. However, current global warming is driven by increasing greenhouse gas concentrations. The Last Interglacial is the most recent time when sea levels were much higher and it's a time for which we have lots of data," McKay adds. "The message is that the last time glaciers and ice sheets melted, sea levels rose by more than eight meters. Much of the world's population lives relatively close to sea level. This is going to have huge impacts, especially on poor countries," he adds. Ocean rising may continue even after warming stops | R&D Mag ----------------------- We have lots of data. Well, the right has plenty of competing data. Like Noah's Ark and the Bible. 6% of scienctists tell us so.
