Ocean Front Property in Arizona

A new study in Nature: Geoscience suggests that current estimates of sea-level rise in response to global warming are too low. Rohling et al. utilize a “combination of a continuous high-resolution sea-level record, based on the stable oxygen isotopes of planktonic foraminifera from the central Red Sea and age constraints from coral data to estimate rates of sea-level change” during the last ice age (124-119 kyr). Their findings indicate in a climate 2 degrees C warmer than the present the oceans were 4-6m higher than the present. Overall, sea-level increased by 1.6m per century. An important factor contributing to this rise was the melting of the Greenland ice sheet.

A 1.6 m global sea-level rise per century would correspond to disappearance of an ice sheet the size of Greenland in roughly four centuries (modelling suggests 1,000 years or more).

The research supports the often criticized, unconventionally high, estimates of 0.5-1.5m sea level rise predicted by AD 2100. The good news? More deep sea!

Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, a National Science Foundation supported initiative. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (http://deepseanews.com/), a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web. His forthcoming book, Science of the South (http://www.scienceofthesouth.com/), connects cultural icons of South such as pecan pie with the science behind them.

  1. So, would it be wrong to start buying up “cheap” land now in anticipation of it’s ocean-front value in the future?

    I mean, someone (or more) must be doing this already, right?

  2. Way to look on the bright side!
    Wouldn’t the simplest way to predict sea level change be to measure the amount of ice, account for the voume change when it turns to water and then add that much to the oceans? I guess that’s not so simple as it seems,actually.

    I lived in the Florida Keys for a year and Hawaii for 6 months so I know about the beauty of the deep sea. But I have chosen Tennessee to live out the rest of the years on outpost Earth, ( seems high enough doesn’t it)? Buying a home in the dessert only to be able to catch fish from the porch later on might be too much of a strain on my heart! LOL!
