Why not use treated sewage water for fracking?  Hmmmm?

One, you're really drawing an analogy between combustion of carbon in your little fire and fusion, well because "nobody's ever actually been there right..."? 

Two.  You don't think that scientists ever take solar cycles into account?  Have you ever even taken a basic grade 9 Earth Science class?  There are many broad factors that control climate cycles.  Solar cycles and orbital variations are major drivers and no scientist anywhere will tell you different.  However, those operate on different time scales than the current observed change.  That is why most scientists think that there is another forcing mechanism at play, one that is operating on a shorter time scale. 

While you're educating us about solar radiation fluctuation and climate change, perhaps you can tell us how many watts per meter squared, on average, were recieved from the sun to the surface of the Earth in each decade for the last several decades.  That way you can demonstrate unequivocably that it is indeed a solar campfire style flare up that accounts for any warming that's been observed over the period of modern temperature records.

Quantity, delivery, cost. 

Not enough generated near fracking locations.  Have to pipe it there.  Much cheaper to suck PA's trout streams dry than to pipe wastewater from PHL. Somebody tries to regulate the industry down that road and you'll be back here complaining about libtarts and job killing regulations.

Besides, in areas with really heavy water use, highly treated wastewater becomes an important source of surface water to sustain flows downstream.

Yeah was a drastic "over simplification - comparison "  but the idea is the same and in all reality just like my "we have not been there" statement I'm not so sure we really have enough true data to draw the conclusions of long term vs short term cycles...  yes lots of hypothesized make us feel good as human being data but I don't think we have enough true hard data.

Do like your idea of

"blah blah were recieved from the sun to the surface of the Earth in each decade for the last several decades"

And iff I didn't arealdy work a full time reseach job in flud mechanics + a second job on the side then other life commitments I would be very very interested to study that. Hmmm if that is monitored and is consitentley going up and up then ughh  we're all fucking screwed

Bottom line is what I was really saying is we are just human - really still animals - and as hard as it is to accept we don't know everything nor will we ever... Somethings are just bigger than us. yes it is good to disccuss and think but something we may never know.Worse thing is we don't learn from our mistakes... take for an example a current event that is a little more concerning than a few degree temp change: the financial situation. What caused the great depression ( other than over extending & greed in the twenties). Goverment intervention ( the tarrif act) and now WTF are we doing trying to solve a problem with goverment intervention @@

BTW do gotta give you props for coming back with a response with some thought in it as oppsoed to the usual crap I read on here like " blah lib this consv this blah f aghh"

And to answer your question about 9th grade... no I was out at the beach that semester with some chicks and a surfboard, but I did go on to college where I took about 4 semesters of quantum theroy then wrote a thesis on nuuclear physics... so can I get half credit from you mister tough guy keyboard?

get up early and go surf - it'll make that hangover go away and/or make the workday more tolerable :)
