permaculture

["J. Kolenovsky" <garden@hal-pc.org>]

Travis, I had a thought that the caron emmision started during the
Industrial Revolution but now see it could go back to the early Holocene
period. If it goes back that early, it could be that all of the history
since has been on a normal path and timeline.

Hmmm. I always wondered about the efficiency of those wood-burning steam
locomotives. They are romantically nostalgic.

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.

This may have some bearing on discussion of how Permaculture can and  
should be used as part of a mitigation response to climate change.
