$this->bbcode_second_pass_quote('GHung', 'K')J: "I have confronted this simple binary choice".
Reducing this to an either/or choice is creating a false choice. I find it rather absurd.
GHung, you haven't been paying attention. I assumed you had the common knowledge of most PO.com members.
The situation was once more complex than it is today. But two centuries ago when we crossed over that magic sustainable population number, our full spectrum of choices were reduced to two. We have discussed this many times here. There are a variety of opinions about what that sustainable population number is. The pessimistic lower limit is around 125 million humans, which assumes nothing in the way of new tech, it simply says we take away mechanized agriculture and petrochemical fertilizers/herbicides/pesticides and use 19th century style agrarian farming methods. The optimistic upper population bound is right around one billion humans, which is the case when you make a series of unlikely assumptions. Among these assumptions is that we can re-purpose and re-deploy 1/4th of the US population as agricultural workers and that they will move voluntarily from the cities to the countryside. Then some modern high efficiency organic agricultural methods can be used and that 75 million Americans will adopt this method and use it as their career, which is growing food for the other 250 million Americans. The most common alternative to modern corporate farming is called "Permaculture", and you will find dozens of threads talking about this topic.
But of course, we crossed over that optimistic high world population bound for the world over two centuries ago, right around the time when the Reverend Thomas Robert Malthus published his treatise
An Essay on the Principle of Population in 1798, and certain educated "Scientists" realized that we had to stop reproducing or the world would end. Over two centuries after that, with that "overshoot population" of more than 6.3 billion humans, our infinite alternative choices are reduced to two: Die here on Earth, or leave it and live. The "answer" of course is BOTH - most humans will perish on the Earth, a few will live in space. As long as that few includes at least 100 or so with the right sets of human genes, we have a viable sample of human diversity. If that few is at least 3500 people, and we select the right 3500 individuals, we can preserve all the diversity of the human species. Has that light bulb come on in your head yet? Because this is only about the two dozenth time I have repeated this to various PO.com members, and told them to search out those earlier threads.
kanon, much of the same comments as above. Many many threads exist here and you seem to be unaware of their contents. But the basic choice available to you is a simple one: You can advocate and support the present world population figure of 7.3+ Billion humans, who are collectively destroying species habitats and generally killing the Earth with a rate of species extinctions that constitute the most rapid and most deadly "extinction event" in the history of the world, or you can profess to be an advocate of the Earth's species diversity, aka the Biosphere, Mother Earth, Gaia, etc. This is a simple binary choice today, those 7.3 billion humans ARE HERE ALREADY, they will not silently vanish into the night for the convenience of a select few such as Americans and Europeans who are fortunate to have more than they need to survive, and therefore may conceivably survive the end of cheap oil, which is certainly going to kill almost everybody on this planet, barring a new miraculous energy source yet to be discovered. In their struggle to survive, the 6.3+ billion excess humans will complete the planet's destruction - either by species extinctions, nuclear or conventional warfare, or pestilence and disease caused by the collapse of modern medicine (the lack of sterile petrochemical items such as the plastics, or the inability to import pharmacology items from around the world, or the lack of affordable energy to synthesize other medicines and run modern medical equipment).
That all of us are LIVING in the midst of this incredibly fast "extinction event" and it mostly escapes our notice does not change anything - you know that the last two centuries are an eyeblink on a geological time scale, and you understand that the second most recent extinction level event recorded in the fossil record happened in the 1300 years or so following the impact of the Chicxulub asteroid as evidenced in the "KT Boundary layer" (aka that thin line of iridium dust that covered the entire planet) 62 million years ago on the Yucatan peninsula. The most deadly mass extinction event recorded in the fossil record was the one in the Permian age when we believe that several simultaneous mega-volcanoes destroyed 95% of existing species and at least 95% of the population of the remaining 5% of species that survived, both plants and animals. If you want to understand the true scope of the problem we face today, the 6.3+ Billion human overshoot population is killing species over 5X as fast as that huge asteroid impact event, and the ecosphere destruction is accelerating and may prove more extensive than the Permian Age event when we had one continent on the Earth called Pangaea.
I am a conscious advocate for Humanity, realizing all too well that we will kill the Earth's ecology for a geological age as we go extinct ourselves. It is a dubious honor at best, to realize that humans are the deadliest thing to ever harm the planetary ecology so far. But you can only be an advocate for the planet by also advocating the genocide of at least 6.3 Billion humans, and I stop short of that position, and consider anybody who is a conscious advocate of "Mother Earth" or whatever other nonsensical term, to be both a genocidal maniac and a hypocrite. As are all PO.com members who claim such a position as an advocate of the planet, while using a PC powered by coal, driving a car powered by oil, and benefiting from sanitation, nutrition, and medicine that are enasbled by fossil fuels alone.
Although it will take another 1-2 centuries to complete, the status of the Earth is GAME OVER MAN. Most of us here (including me) have settled on a timeline for TEOTWAWKI which is on the order of 80 years from today, and is a direct result of running out of cheap oil. That actually means that we would be surprised to have the world end faster than 8 years from today, or longer than about 160 years. The "most likely" date, the peak of the bell curve, the highest probability, is about 2095 AD.
I cannot prove that there are no working climate models either, since no one person has access to all of them, and only some are in the public domain. If I remember my undergraduate Philosophy courses, it is impossible to "prove a negative". So I will reverse that one on you, and if anyone knows of an actual working climate model, we can examine the claim. I believe that they are ALL defective, because nobody has produced a model that survives what I call the "acid test", which is you feed the model historical data and use it to predict future temperatures (either at a single location, a single altitude, or the entire planet depending upon the model being discussed). Those temperatures exist as recorded temperatures and none of the models used have had any accuracy to speak of outside of a single decade, beginning with Al Gore's "Hockey Stick" temperature spike that was going to kill us all by 2002. However, for the last 35 years we HAVE had access to the direct temperature data (based on integrating the infrared radiation intensity over the visible hemisphere as observed from Earth facing satellites). Unfortunately these temperatures are not rising as predicted by any AGW theories I know of - and the AGW fanboys do have an incredible number of excuses for this, some of which were regurgitated in this thread.
The information that the higher carbon dioxide levels of the atmosphere have caused an observed increase in greenery of 14% worldwide was news to me, and generated my speculation about negative feedbacks and Homeostasis.
