Took a look at couple of those at random.. Let me show you how stupid you are to cut and paste WITHOUT reading any of the paper details.. Let's take THIS ONE....

Abstract
We present paleoclimate evidence for rapid ( < 100 years) shifts of f 2–4 jC in Chesapeake Bay (CB) temperature from 2100, 1600, 950, 650, 400 and 150 years before present (years BP) reconstructed from magnesium/calcium (Mg/Ca) paleothermometry. These include large temperature excursions during the Little Ice Age (f1400 – 1900 AD) and the Medieval Warm Period (f800 – 1300 AD) possibly related to changes in the strength of North Atlantic thermohaline circulation (THC). Evidence is presented for a long period of sustained regional and North Atlantic-wide warmth with low-amplitude temperature variability between f450 and 1000 AD. In addition to centennial-scale temperature shifts, the existence of numerous temperature maxima between 2200 and 250 years BP (average f70 years) suggests that multi-decadal processes typical of the North Atlantic Oscillation (NAO) are an inherent feature of late Holocene climate. However, late 19th and 20th century temperature extremes in Chesapeake Bay associated with NAO climate variability exceeded those of the prior 2000 years,
including the interval 450 – 1000 AD, by 2 – 3 jC, suggesting anomalous recent behavior of the climate system.
Which AGAIN bolsters every assertion I've made about LOCAL versus GLOBAL proxy studies..
They found NATURAL VARIABILITY in shallow WATER temperature of 2 to 4 degC.. In less than 100 YEARS !!!!
Now that's NOT the same as ATMOS temperature. In fact, it's harder to affect those those insulated little mudbugs they study several tens of METERS below the surface of Cheasapeake Bay..
AND those 2 to 3 degC water temperature shifts?? Not fully resolved. Could have been higher. Doubtfully lower. And you're still convinced that the 0.6degC shift in GLOBAL air temperature in your lifetime is COMPLETELY man made and unnatural??
Several probs with this paper. One is fairly obvious and I'll leave it to you to explore and find it.. But THANKS for calling it to my attention and I will certainly add this to my files to contradict the TRUE hockey sticks of Mann and the others that give the impression that there is VIRTUALLY NO natural variability in the climate history before the 20th century..
Again -- LOCAL individual proxies show MORE resolution and MORE natural variation than found in the juvenile attempts to extend 70 or 80 proxies to a GLOBAL reconstruction..
