wow that avatar is the most depressing thing i have ever seen.
ha ya and us drill baby drill is the cause of it. truth hurts huh.
and yes i posted hundreds of times just so i can do that. go to speculation....jr members are getting ripped to pieces. just saying. but in the end my PA is pointless and is on deaf ears. oh well i tried.
How is drilling for oil responsible for killing polar bears? im not saying it isn't i just wanna understand the mechanism.
anytime that we release cretin gases in the air like carbon dioxide it has a positive feedback system. a positive feed back system would be like this the sun heats and melts the snow at a slow pase but with polution the snow is not so white so black (even off white) absorbs more heat instead of reflecting back into the atmosphere, then since the surrounding few rocks that are poking out are darker in color absorb more heat more snow melts this creates more patches of snow free areas this in turn makes the snow melt even faster. etc etc etc. or the other way like say it gets cold and its fall and we get out first snow. the next day we have clear skys but its freeeeezing...why? because all the suns rays are being reflected back to space making it colder still so then the next rain/snow storm comes in and its so cold still that you ge tmore snow ans so on and so forth. also the heat from all the engins and machines and coal being burned heats up the earth. also when the earth heats up a little then the perm a frost melts .....under the perm a frost you have methane 50 to 100 times more powerful global warming agent than carbon... also interestingly the half life of methane is carbon. so after 50 years of methane killing the ozone and heating up the earth it turns into carbon the second worst contributer to heating up the earth this lastes for another 150 to 200 years. also we dont see the polutin that we put out for 50 years .... meaning that what we see today is from what polution we put in to the air 50 years ago...in the 1963. In fact the earth in the normal heating and cooling cycles should be going back to an ice age where the ice would be adventuring every winter. instead we see the poller ice caps melt at unprecedented rates. also we will see (with warmer sees) more mass destruction from weather and hurricanes.
so to answer your question polar bears are suted and addapted for pur snow and ice coverd seas. if these melt then we will not have polar bears as a species anymore. and we will see them as stuffed atractions like the saber toothed cat and the woolymamoth.
reference from: in getting my BS in Psychology i got a minor in earth science. i have also worked on an oil rig... well a fracking rig and a deep deep BIG rig that goes 4 miles into the earth. huge blow outs of pure gas goes strait into the atmosphere. we are slowly killing the beautiful place we call home.....all for a buck. so sad. thats why i quit .... 36 per hour but my morals are worth more than that. ill work at a zoo or a forest ranger for 8 hr as long as im not contributing to killing our planet home
so
Every positive feedback model that has been around long enough to be tested against the empirical data has been proven false. Yes co2 causes some warming but sorry there are no feedbacks. See the work of David Evans, he has written extensively the feedback amplification its testing against empirical data.
which is unfortunate really, because we could really deal with a bit of global warming. Planet earth has a great deal more landmass that is uninhabitable due to extreme cold than extreme heat, so i higher global temperature would allow for a higher population.
this is so incredibly false i dont know where to begin. lets see most of the earth is coverd in water, the land mass is 60% desert. with higher temps we would have even more droughts. thus less crops thus less people. also 80% of all humans live in costal areas. if all the ice caps melt then we are talking 6+ feet water increase. thus these people must move and again less land and crops to suport lives. imo redneck republican thinking is going to kill the planet but unfortunatly by the time we enlightend taken a class and got a degree type can say "told ya so" it will be to late.
Positive feedback is a process in which the effects of a small disturbance on a system include an increase in the magnitude of the perturbation.[1] That is, A produces more of B which in turn produces more of A.[2] In contrast, a system in which the results of a change act to reduce or counteract it has negative feedback.[1][3]
Mathematically, positive feedback is defined as a positive loop gain around a feedback loop.[1][3] That is, positive feedback is in phase with the input, in the sense that it adds to make the input larger.[4][5] Positive feedback tends to cause system instability. When the loop gain is positive and above 1, there will typically be exponential growth, increasing oscillations or divergences from equilibrium.[3] System parameters will typically accelerate towards extreme values, which may damage or destroy the system, or may end with the system latched into a new stable state. Positive feedback may be controlled by signals in the system being filtered, damped, or limited, or it can be cancelled or reduced by adding negative feedback.
Positive feedback is used in digital electronics to force voltages away from intermediate voltages into '0' and '1' states. On the other hand, thermal runaway is a positive feedback that can destroy semiconductor junctions. Positive feedback in chemical reactions can increase the rate of reactions, and in some cases can lead to explosions. Positive feedback in mechanical design causes tipping-point, or 'over-centre', mechanisms to snap into position, for example in switches and locking pliers. Out of control, it can cause bridges to collapse. Positive feedback in economic systems can cause boom-then-bust cycles. If a PA system's microphone picks up sounds from its own loudspeakers, and these sounds are re-amplified enough, the effect of this feedback can be loud squealing or howling noises from the loudspeakers. it is a term often used in collage type atmosphere. probably not much on the ol ranch a buddy
thats ok if you dont understand it, its not my job to teach every closed mined individual on this amazingly diverse and oh so intelligent forum.
you bring a quality that this forum so desperately needs. congratulations on your success and good luck in the future. haha
