"What the F*** is a closed feedback system?"
"Thank you Buck Wheat. Yes, The Earth is an excellent example of a closed feedback system. A Closed Feedback System, or CFS 'cuz I'm gonna get damn sick of typing that, is a cycle (or circular path) of some stuff in which none of that stuff can be taken out or added. What you see is what you got. "
"LIKE DAH ERF!!!"
"Yes Buck Wheat, like the Earth." They (the people that employ teachers) don't pay me enough for this shit,
"In a CFS, like the Earth, material cannot be added nor removed (for all intensive purposes we'll leave out a few tons of meteors and man-made satellites), the material just changes forms. A very complex cycle within the earth that can be explained in an oversimplified, but not horribly inaccurate, way is the planet's hydrologic cycle."
"Well Sindy*, The basic pattern of movement of a water molecule around & within the Earth (including the atmosphere) is what is referred to as the HYDRO- (Greek for water) - LOGIC (from the Greek logos, "to go") Cycle (not spelling that one out- GOOGLE it)."
"SOH, MIZ TEECHA... HOW DAT LIIK DAH ERF?"
"FIRST., it is not like the earth, it is part of the earth. and the earth is composed of an infinite number of closed, open, circular, linear and web-like systems. The hydro-cycle is just one of them...."
"SINDY! MOVING ON!,... The hydrologic cycle's main reservoir, its base, is the Ocean. (they're all connected- there's really only one. Tell the fish otherwise.) Water starts in the Ocean, it evaporates into the atmosphere, is held in clouds, condenses and falls as precipitation, lands either back in the ocean, or on land.
When it falls on land; it either drains into rivers (& back to the Ocean), is consumed by animals, plants or aquifers. Animals get the water from plants, atmosphere, rivers and aquifers and then piss the water back into where they got it from. Plants get water from the atmosphere, rivers, or aquifers and then give it back to the same places they got it from. Aquifers just store it underground to be taken out later. And rivers take all the water from the runoff from all the land-based intakes and bring it all back into the Ocean,
where it came from in the first place. A closed circuit...
...Shit. that got a little wordy in the land area of the cycle... so... from sea to air to land to river and back to sea. oooohff."
"You said there were others?"
"You betcha baby! There is the cycle of the earth's crust, nuclear waste, the CIRCLE OF LIFE - OH-OOH-OH-OH-OH-OH! <down Elton! down!>,
<<<<Ahhhh! side note, i realize that the cycle of planetary warming and cooling due to its elliptical orbits around the sun, center of galaxy, etc. prove that the earth is not a closed circuit system, but for the sake of argument (and the planet of which i would like to save, maybe not here but it would be nice - & i would like to, want to bring a child into the world, but only a world i actually believe will be there for them) just let the particulars that i don't need to explain to the people who i don't need to convince otherwise because they already get this slide. I want the 'pop' audience to be able to be both able to grasp this shit and be entertained enough to read it to get to the point... and maybe, just maybe, get the point i am trying to make; GET OVER YOURSELVES! YOU CAN'T-WON'T-SHOULDN'T MATTER IF YOU DON'T LEAVE A PLACE FOR YOUR FUTURE DESCENDANTS TO APPRECIATE OR EVEN REMEMBER YOU, & - FOR THAT MATTER LIVE!!!.
Yeah ALL CAPS, unleash the fury.>>>>>
....cont. from earlier... "So the Earth is composed of many of these systems."
"SOH HOW DAT MATTAH?"
"Thank you Buck Wheat for cutting off Sindy. Now, that matters because of the nature of a closed feedback system. everything moves around the system in, essentially, a circle. But, like swinging a weight tied to the end of a rope---- the heavier the weight, the hard and faster it will spin, with less and less input on your behalf, as you swing it around. Yup, that fundamental law of Newtonian Physics - INERTIA BITCHES!'
So, the more weight lumped one end of a Closed Feedback System the harder and faster it will cycle.
"BUT HOW DIS GONNA HEP ME? WHAD ID AWWL MEEEEEN? WHAT ABOUT DAH ERF?"
"Seriously Buck Wheat, we get it. The Eart-"
"NO U DONT U DUMB BITH!!! HOO DAH HEWW GONNA SABE ME FROM MY NAN'S SPRINKLA SI-TEM, BEEPH BURGAH EV-Y DAY, AND DAH DAM OWD-MOBEEL!!! HOO DA HEWW DO I GOTTA CLUB WIFF MAH SHOOO?!?!?!?!?
So if you drain all the planets aquifers, melt all its stored ice, heat up the atmosphere, and dam & drain the rivers, and cut down the trees.... emptying all the stores of water but one.... don't be surprised when the one remaining store of water gets really really full and tries often and violently to put some back...
....yes the Ocean. it will fill up. the water will move up the rim of the glass, and a full glass is much easier to spill than an empty one...
how does the glass of water that is the ocean spill onto the land? Rain, Sleet, Snow, and big fucking waves...
...YOU GET IT YET?"

Consider this next time you hear or see a story about weather/ climate change/ global warming:
Why is it still news that: IF you have a bunch of closed feedback systems all interacting with each and every other system, in that lager system, that is composed of almost all closed feedback systems & subject to the patterns of exponential growth that closed systems typically are, THEN when one or two systems spiral out of balance it is almost guaranteed that all the other systems will follow, spiraling out of control – so far beyond any known tipping point that it is to the edge, or beyond, current comprehension? And why is survival in the face of this reality NOT THE ONLY discussion being had?
