(10,575 posts)8. Are there prehistoric data points for typhoons, like some claim for hurricanes in Florida?
Liu, K.B. and Fearn, M.L. 2000. Reconstruction of prehistoric landfall frequencies of catastrophic hurricanes in northwestern Florida from lake sediment records. Quaternary Research 54:238-45.
ABSTRACT
Sediment cores from Western Lake provide a 7000-yr record of coastal environmental changes and catastrophic hurricane land-falls along the Gulf Coast of the Florida Panhandle. Using Hurricane Opal as a modern analog, we infer that overwash sand layers occurring near the center of the lake were caused by catastrophic hurricanes of category 4 or 5 intensity. Few catastrophic hurricanes struck the Western Lake area during two quiescent
periods 3400-5000 and 0-1000 "C yr B.P. The landfall probabilities increased dramatically to ca. 0.5% per yr during an "hyperactive" period from 1000-3400 "C yr B.P., especially in the first millennium A.D. The millennial-scale variability in catastrophic hurricane landfalls along the Gulf Coast is probably controlled by shifts in the position of the jet stream and the Bermuda High.

I think the AP is wrong in saying climate change is responsible "to a much lesser degree"

The AP threw those words in to prevent thousand of teabaggers from foaming at the mouth

So do you believe all the climate scientists who say climate change is a serious issue are "nutty"?

Absolutely not, and in fact, you *completely* missed the point I was trying to make.

I didn't say that *YOU* did that. I merely said that it has been done before.

I admit that some parts were poorly written but it didn't change the intent of said statement......

If a significant number of people made such a claim it would not take hours of Googling

That is absolutely false, there is much scientific evidence that shows climate change is serious

Maybe you need reading comprehension because it was the AP who made the conclusive statement

"climate change is happening and it is human caused." OK, and nobody's argued otherwise.

They can't conclusively say that climate change is only responsible to a "much lesser extent" either
