Rather than complain to just one person, the OP, do us all a favor and spend your time--only a few seconds--to copy the text into a word processor and suit yourself to every possible whim you can imagine such as colors, font sizes, bullets, indents, layouts, etc. That would be, oh, so much more fun and enlightening to yourthan a bitch about what you don't like to read. Give us a break. Grow up and get serious.
Abstract
Evidence for an anomalous annual periodicity in certain nuclear decay data has led to speculation concerning a possible solar influence on nuclear processes. As a test of this hypothesis, we here search for evidence in decay data that might be indicative of a process involving solar rotation, focusing on data for 32Si and 36Cl decay rates acquired at the Brookhaven National Laboratory. Examination of the power spectrum over a range of frequencies (10–15 year−1) appropriate for solar synodic rotation rates reveals several periodicities, the most prominent being one at 11.18 year−1 with power 20.76. We evaluate the significance of this peak in terms of the false-alarm probability, by means of the shuffle test, and also by means of a new test (the “shake” test) that involves small random time displacements. The last two tests are the more robust, and indicate that the peak at 11.18 year−1 would arise by chance only once out of about 107 trials. However, the fact that there are several peaks in the rotational search band suggests that modulation of the count rate involves several low-Q oscillations rather than a single high-Q oscillation, possibly indicative of a partly stochastic process. To pursue this possibility, we investigate the running-mean of the power spectrum, and identify a major peak at 11.93 year−1 with peak running-mean power 4.08. Application of the shuffle test indicates that there is less than one chance in 1011of finding by chance a value as large as 4.08. Application of the shake test leads to a more restrictive result that there is less than one chance in 1015 of finding by chance a value as large as 4.08. We find that there is notable agreement in the running-mean power spectra in the rotational search band formed from BNL data and from ACRIM total solar irradiance data. Since rotation rate estimates derived from irradiance data have been found to be closely related to rotation rate estimates derived from low-energy solar neutrino data, this result supports the recent conjecture that solar neutrinos may be responsible for variations in nuclear decay rates. We also carry out a similar comparison with local temperature measurements, but find no similarity between power spectra formed from BNL measurements and from local temperature measurements.

The way the article is written, it sounds like the author is very skeptical of what evidence has been uncovered so far. Clearly the author is not the first to make these observation, merely confirming the test results obtained by others. This much is clear in the first sentence.

I don't see how this can be the "original peer reviewed article". Clearly this article is a review itself, which begrudgingly admits to finding similar results.

Have any links to back up your claim.
The author in the link states this.
But as you can see, carbon dating makes one huge assumption: radioactive decay rates remain constant and always have been constant. If this new finding is proven to be correct, even if the impact is small, it will throw the science community into a spin.
On what basis would it be established that the variability is significant or insignificant? On what basis do they determine how much variability exists, and the duration cycles of these variations. Odds are greater that this variability is larger than we have yet to observe.
Calculate in the possible durations of this variability, and there could be considerable discrepancies.

An abstract is a brief summary of a research article, thesis, review, conference proceeding or any in-depth analysis of a particular subject or discipline, and is often used to help the reader quickly ascertain the paper's purpose.

With science advancing at break-neck speeds, if everyone freaks out every time we find something new, we're going to end up back in another dark age.
If you look at the age of the universe versus the extremely short time we've been recording data about our world, we know NOTHING. We don't know if these things happen all the time, on a regular or irregular basis, whether it means something or not.
It's very interesting, but not worth freaking out about.
