What was done
The authors studied numerous depositional environments along the tectonically stable, unglaciated eastern Chuckchi Sea coast that stretches across northwest Alaska, deriving a 6000-year record of sea level change, while simultaneously learning some interesting things about the correlation between storminess and climate in that part of the world.

What was learned
The reconstructed sea level history was suggestive of a modest mean rate of sea level rise on the order of a quarter of a millimeter per year over the past six millennia, which was interspersed with several periods of more rapid fluctuations of a decadal or centennial nature.  Mason and Jordan also learned that "in the Chukchi Sea, storm frequency is correlated with colder rather than warmer climatic conditions."  Consequently, they say that their data "do not therefore support predictions of more frequent or intense coastal storms associated with atmospheric warming for this region."

What it means
Once again, climate alarmists take it on the chin, when they talk about sea levels and storminess raging out of control in response to the "unprecedented" global warming that they attribute to increasing concentrations of atmospheric greenhouse gases.  In a diametrically-opposed conclusion, the authors of the current study say that their bottom-line finding "provides good news for disaster planners in northern Alaska," and, we would add, the rest of the world as well.
