I recently read a paper on a theory that anthropogenic warming
actually started thousands of years ago. The gist of the paper is
that anomalous quantities of CH2 and CO2 have been dated to the
early part of the holocene period. The methane increases are along
the same timeline as the increased use in domesticated ungulates and
the CO2 increases are on the same timeline as deforestation by humans
for use as farmland. The hypothesis is that the domestication of
animals and clearing of land got the global warming ball rolling and
extended the cyclical warm period between glaciation and that we'd be
well into an ice age if it wasn't for human activity. Essentially,
agriculture created global warming and industrialization made it more
severe. I'm not a climate scientist but the data and the basic
premise seemed to make sense.
Here is a link to the paper on Stanford's website.
