Guest post by David Motes- "GW driven by Plant Evapotranspiration Reduction, not CO2 GHG. Solution- More Plants".

"David Motes is a 43-year professional chemical engineer residing in Houston, TX.  His 23 page engineering paper as a guest post is titled: "Global Warming Driven by Plant Evapotranspiration Reduction, Not CO2 GHG!  Solution- More Plants".  The paper is summarized as follows:  Anthropogenic Global Warming (AGW) is quantitatively driven by CO2 induced Plant Evapotranspiration Reduction (PER), not CO2 GreenHouse Gas (GHG) effects.  David uses consensus science facts and diagrams from CO2 GHG proponent sites such as the IPCC, NASA, NOAA, and the International Energy Agency to quantitatively prove the scientific fact that PER is a significant driver in AGW.  Conversely, CO2 GHG theory remains a largely unquantifiable, problematic theory.  By example, 10 CO2 GHG theory problems are quantified and graphically presented.  His focus was on engineering quantification versus hereto date presentation of GHG data and theories.  Increasing plant life is less expensive and substantially more effective than just reducing annual fossil fuel CO2 emissions (contributes only 1% of existing atmospheric CO2).  His paper, engineering quantification, and science is well worth reading and further research" Click to view a pdf on DocDroid.com.

This is David, the author. I am happy to reply to any comments or questions on the post. I realize this engineering paper takes time to read and understand. Thanks! David.

Thanks for your work David. Much of it dovetails with work I and others are working. Question: What mechanism do you think is causing humidity should to be decreasing?

Thanks for your work on this David.

What mechanism do you think is causing humidity to decrease?

Much of your work seems to dovetail well with the Henry's Law theory I attempt to explain, but the references may do a better job.

Bud Bromley, thanks for the feedback.
Cause of relative humidity drop- 81% of the relative humidity decrease is generated by a CO2 induced 0.70%/year plant water use efficiency increase. See my paper, page 21, Botanical Quantifications, calculation on page 22.
Concerning Henry's law application to ocean and atmospheric CO2 concentration- Henry's law unfortunately does not apply because the liquid and gas must be in equilibrium contact, not the case. "Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality factor is called Henry's law constant. H = Ca / p." The ocean on average is ~5% saturated (undersaturated) with CO2 per Henry's law at 410ppm CO2 in atmosphere and 41ppm average CO2 in oceans.
See my paper, calculation on page 6, Problem 4. The ocean concentration is limited by mass transfer between liquid ocean and gas atmosphere, not by CO2 solubility in sea water.
I hope this helps. My email is davidmotes7-at-gmail-dot-com if you want to contact me. Thanks! David.
