For the study, the researchers performed stable isotope analyses on 712 animal bones collected from at least 90 archaeological sites in Ireland. The researchers found significant changes in the nitrogen composition of soil nutrients and plants that made up the animals' diet during the Bronze Age.
The researchers believe the changes were the result of an increase in the scale and intensity of deforestation, agriculture and pastoral farming.
While these results are specific to Ireland during the Bronze Age, Guiry said the findings have global implications.
"The effect of human activities on soil nitrogen composition may be traceable wherever humans have extensively modified landscapes for agriculture," he explained. "Our findings have significant potential to serve as a model for future research."

Ban everything: it pollutes, poisons, modifies, catastrophizes!
Barring that, I’d settle for banning Leftists: they pollute and poison minds.
Some of the areas shown on the following map (University of Nebraska at Lincoln as linked from the NOAA) have been misreported. Much of the corn is now about eight feet high in areas very close to the University at Lincoln—areas that have been reported as being in “severe drought.” That corn has received no artificial irrigation at all this season.
Rains have been frequent, not that it matters. Because humidity has also been running near 100% much of the time, including the period of the heat wave that just ended there.

Science: it’s only as good as the level of honesty of those who administer its undertakings.
Little correction here. The map should be replaced with a new one at around 8:30 AM, Eastern Time (about 5:30 or 6:30, dry, sterile Pacific and Mountain Time).
Interesting set of articles.
I just finished up 1493 and 1491 by Charles Mann. There’s a lot of discussion there about the impact of agriculture on the land.
O my God, civilization is going tobe kill us through climate change.
Thanks, SunkenCiv!
It’s our education system producing advanced degrees and doctorates as if getting charged piece work rates that is producing so many unfit scientists.
Since there's no apparent impact on anything from the change in nitrogen isotopes, this is one of those 'first shoe" studies that will be trotted out in footnote as if it supported the notion of AGW. There's not any evidence that there has been any deleterious impact on ANYTHING or ANYONE from this alleged change. Int the topic about rats' impact in Polynesia, I included a snip about nitrogen.
Thank you.
I was mistaken about when the new map is published. That should be this morning at 8:30 AM Eastern—not yesterday.
