A High-Intensity Hurricane Record Preserved in a Florida Sinkhole
Reference
Lane, P., Donnelly, J.P., Woodruff, J.D. and Hawkes, A.D. 2011. A decadally-resolved paleohurricane record archived in the late Holocene sediments of a Florida sinkhole. Marine Geology 287: 14-30.
Background
Noting that "the brief observational record is inadequate for characterizing natural variability in hurricane activity occurring on longer than multi-decadal timescales," the authors sought a means of characterizing hurricane activity prior to the period of modern measurement and historical record keeping, due to the fact that "the manner in which tropical cyclone activity and climate interact has critical implications for society and is not well understood."
What was done
Lane et al. developed a 4500-year record of intense hurricane-induced storm surges based on data obtained from "a nearly circular, 200-m-diameter cover-collapse sinkhole (Mullet Pond: 29°55.520'N, 84°20.275'W) that is located on Bald Point near Apalachee Bay, Florida, USA, where (1) "recent deposition of sand layers in the upper sediments of the pond was found to be contemporaneous with significant, historic storm surges at the site modeled using SLOSH and the Best Track, post-1851 AD dataset," where (2) "paleohurricane deposits were identified by sand content and dated using radiocarbon-based age models," and where (3) "marine-indicative foraminifera, some originating at least 5 km offshore, were present in several modern and ancient storm deposits."
What was learned
The four researchers' reconstructed record of intense hurricanes revealed that the frequency of these "high-magnitude" events "peaked near 6 storms per century between 2800 and 2300 years ago." Thereafter, it suggests that they were "relatively rare" with "about 0-3 storms per century occurring between 1900 and 1600 years ago," after which they state that these super-storms exhibited a marked decline, which "began around 600 years ago" and has persisted through the present with "below average frequency over the last 150 years when compared to the preceding five millennia."
What it means
It is instructive to note that over the past century and a half of ever-increasing fossil fuel utilization and atmospheric CO2 buildup, the frequency of the most intense category of hurricanes in the Northeastern Gulf of Mexico has been lower than it was over the prior five millennia, which speaks volumes about the climate-alarmist claim that continued anthropogenic CO2 emissions will lead to more frequent super cyclones and hurricanes.
I lived on and nearby LBI for over ten years. Proud homeowners in the area at some point will be the victims of underlying shoddy construction when a hurricane or even an above average storm swell goes through.
I saw the examples first hand when tipped off by a local builder. His work was top notch. Some of the rest ... not so much.
Huh? WTLJKISDRHDEP
When I was little I read a story in Reader’s Digest about a family building their home in the South in order to withstand a hurricane. I think they used 3/4 plywood for the roof and used nails long enough to bend them over on the other side so they couldn’t be pulled out. They did have a hurricane and about the only bad thing was that their house floated off its foundation with them in it, but it wasn’t destroyed.

I was just looking through that paper about the hurricanes. It appears that the weakest storms coincided with the periods of greatest global warmth and the strongest storms, with the periods of greatest cooling. So the Medieval Climate Optimum showed a decrease. The LIA showed an increase followed by that big drop that continues to now. Farther back, the Roman Warming period had smaller numbers of weaker storms, as low as now, and before that, in the cooler period between the Minoan Warming and the Roman Warming, there was the greatest number of really large storms over the entire period in question.
The organization "Climate Central" in Princeton, New Jersey... found global warming is expanding sea water and causing ice sheets to melt.Which is weird, because neither of those things is happening It's the same BS about "seas are warming at depth", something that's not only not true, but is physically impossible. It's almost as if they just made it up, or stole the bogus study from someone else who'd made it up.
The thing that pi$$ed me off was hearing this crap; as an interview yesterday on WTOP in Washington. The breathless “interviewer” treated the Climate Central rep like an authoritative source. I was like: “Wait. What?” as the kids say.

Whoops, thanks moose07!
Ssssh. Don’t upset the global warming change scammers. I’m sure they would be heartbroken if they realized that forcing the climate into a cooling cycle would increase the frequency and severity of hurricanes.
Apparently they’re not concerned about triggering an ice age.
I realize I don’t get out much. What is a snookie? Is it some endangered animal?
