Hi Folks,

I found this JASON study on "Methods for Remote Determination of CO2 Emissions" and here is the link http://www.fas.org/irp/agency/dod/jason/emissions.pdf

One of the conclusions of the study is the need for a $500 sensor which can be used in a large network. A preliminary proposal for a "Challenge" type competition is mentioned.

Just to note, that even if there were no fossil-fuel CO2 emissions from the 5.5 or so billion people in the developing world, continued emissions at the level of emissions of the 1+B or so in the developed world, climate change would be a pending risk—to keep the CO2 concentration from changing, emissions need to drop by 80+% or so. Thus, it is really our choices that are critical—a small number of people could also cause a significant impacts (CFC use being another example). So, let's not try blaming others—developed nations made an unfortunate choice (and that this was the case was recognized quite a few decades ago—so, even if necessary at the start, the level of emissions could have been a good bit lower) and developing nations are just following our unfortunate example—and now we all need to change where our energy comes from. Developed nations need to demonstrate that a modern economy can prosper with low fossil fuel emissions—until committed to that, preaching to others is rather hypocritical.

Steve,



The world may well be a better place with an order-or-magnitude fewer people, and this would markedly diminish environmental problems.



However, in the next decades the increase in emissions tied to population growth is likely to be substantially less than 50% (ie, a factor of 1.5), whereas per-capita development at 3% per year sustained for a century is approximately a factor of 20.



So, population growth without development might increase emissions by a factor of 1.5. Development without population growth might increase emissions by a factor of 20. Together, they would increase emissions by a factor of 30. If we want to knock that 30 down to a factor of 0.5 or 0.1 or 0.01, we will need to depend heavily on technological innovation. Population measures just don't give us all that much leverage.



So, it is important to recognize the role of population, but we should not neglect the other processes driving increased resource use and pollution creation.



Best,



Ken

Many thanks for all Ken, Mike, Andrew, John Latham, John Gorman and other colleagues are doing to protect biodiversity from massive extinction and preserve Earth's ecology from irreversible degradation.



I hope it is all right for me to post now here a presentation on the issue of population, that appears to have everything to do with climate change.



As humanity's most luminous beacon of truth, science provides us with a last best hope for the survival of life as we know it on Earth. We must make certain that scientific evidence is never downplayed, distorted and denied by religious dogma, politics or ideological idiocy.



Let us not fail for another year to acknowledge extant research of human population dynamics. The willful refusal of many too many experts to assume their responsibilities to science and perform their duties to humanity could be one of the most colossal mistakes in human history. Such woefully inadequate behavior, as is evident in an incredible conspiracy of silence among experts, will soon enough be replaced with truthful expressions by those in possession of clear vision, adequate foresight, intellectual honesty and moral courage.



Hopefully leading thinkers and researchers will not continue supressing scientific evidence of human population dynamics and instead heed the words of Nobel Laureate Sir John Sulston regarding the emerging and converging, human-driven global challenges that loom ominously before humankind in our time, “we've got to make sure that population is recognized.... as a multiplier of many others. We've got to make sure that population really does peak out when we hope it will.”



Sir John goes on, “what we want to do is to see the issue of population in the open, dispassionately discussed.... and then we'll see where it goes.”



In what is admittedly a feeble effort to help John Sulston fulfill his charge to examine all available scientific evidence regarding human population dynamics, please give careful consideration to the following presentation and then take time to rigorously scrutinize the not yet overthrown science from Russell Hopfenberg and David Pimentel regarding human population dynamics and human overpopulation.

Please accept this invitation to discern the best available science of human population dynamics and human overpopulation; discover the facts; deliberate; draw logical conclusions; and disseminate the knowledge widely.



Thank you,



Steve Salmony

Hello All,



Absence of perfection in any human activity involving

more than one person (at most) is virtually inevitable.



Overall,I have found the blogs that Ken initiated to be of

great value in many ways, and in my view we owe him

a hearty vote of thanks, which should also be extended

to those others who have devoted a lot of time to keeping

them running.



Cheers, John. [email protected]
