[Terrapreta] Anthropogenic casue for Global Warming

[David Yarrow]

i have lived in the finger lakes, at the southeast corner of the great lakes.  i can vouch that clouds forms over lakes.  i have watched summer cumulus condense over a finger lake, then slowly fade to wisps as the prevailing winds blew the clouds beyond the lake.  it's rather magical to watch at higher speed.

a similar system operates on a grander scale to create the lake effect snow storms that last winter dumped over 12 feet of snow south and east of lakes michigan, erie and ontario.  these lake effect snow bursts are already cranking up this year as arctic air descends and crosses the warmerthan usual lake waters.

however, in the final equations for the overall global condition, i think the warming of surface waters (oceans, estuaries & lakes) has a greater effect than any extra surface area created by man-made dams.  actually, despite the man-made reserviors, overall water surface area may have declined due to the widespread drainage and destruction of swamps, wetlands, floodplains, and other loss of natural wetlands to agriculture & development.  add to the greenhouse heating of water the warmth added by powerplants (nuclear & coal) and other industries, plus sewage treatment plants, and we are looking at a significant bump in water temperatures woldwide -- especially waters of the industrialized world.

and it is a rule in these northern climates that in a winter greenhouse, soil temperature is more critical than air temperature.  and water is nature's ultimate natural heat sink.

              Thanks Michael,



              So it's a bit of anthropogenic global warming theory compounded with direct observations over the last 30 years or so.



  My questions were a bit rhetorical and intended to illustrate that there are is lot of speculation floating around the global warming sphere that is not necessarily supported by empirical evidence. I guess those dams would have an effect even if not easily measurable on a global scale. Having lived near the Great Lakes in Canada, I can vouch for their efficacy in creating "lake effect" snow. I'm looking forward to your evidence.

  Michael! I wonder how that alleged increase of water vapor was determined and what the base case of comparison is? Is it an assumption of increased evaporation from global warming? Warmer oceans? Inferred from some other kind of

  Here is the article

    I do not know how much the area of water surface was increased by the construction of dams above the existing area of water surface in the oceans already.    Wouldn't you think so?


  Yes intuitively you would. but I remember reading an article about this and being shocked by the area of new man made lakes we had made in the last 70-100 years.
  I am sorry I read this along time ago and I read so many environment science type articles I can't remember the details.. 
  (Later toady-got to go now-I wll see if I can support my bold assertion with some facts via google.)

  This is "two birds with one stone"!  Why not?  Why isn't "biochar" (charcoal made from biomass) the best choice for Terra Preta Nova?



  You will get no arguments from me on this.
  Although i would like to see most char come from pyrolisis so the energy can be harvested and as many polluting gasses as possible are contained. The rush to make char in the backyard worries me a bit. 

  I think TP is the best way of sequestering carbon I have seen or read about. That is why I keep protelyzing  about it
