Some blog followers might be interested in a recent post “CU-Boulder Plots To Extend Life of Al Bartlett's Famous Lecture on Arithmetic, Population, and Energy” [Hake (2013)]. The abstract reads:
ABSTRACT: A report “CU-Boulder plots to extend life of Al Bartlett's famous lecture” [Anas (2013)] at http://bit.ly/16Cxvw1 describes a program of CU’s Environmental Center to train people to give Bartlett’s talk “Arithmetic, Population, and Energy” http://bit.ly/1e6wXiy.
As I stated in my post “A Global Tribute to Al Bartlett” [Hake 2013)] at http://yhoo.it/15N8pfj: “I realize that some overpopulation deniers mistakenly claim that exponential growth is not relevant because the human population of developed countries is no longer increasing exponentially and is even starting to level out. But exponential growth is still present in many parts of the world and is responsible for the initiation of the World’s present human overpopulation . . . . . .”
A typical overpopulation denier is one “dancing badger” who commented as follows on Anas’ report: “[Bartlett’s] arguments regarding overpopulation have proven to be flawed. Once a country reaches maturity in terms of its economy and technological advancement its fertility rate plummets. We have seen this in Europe, Asia and the United States where populations are actually shrinking. The United Nations’ own projections show total global population reaching a maximum of around 11 billion and then declining after that. As a threat the population bomb has proven to be a complete bust.”
A cogent response to “dancing badger” is provided by Bartlett himself in one of his latest essays “Close the Fire Department,” now online at http://bit.ly/13wgHCI, thanks to Marilyn Hempel, (2013), editor of the Population Press. In that essay Al describes his experience at a recent AAAS symposium on sustainability where a panelist, in answer to Al’s question as to why the obvious benefits of reducing our present overpopulation were never mentioned, explained that “United Nations figures show that the growth rate of world population is declining and world population growth is expected to stop on its own later in the century. So the population is under control and there is no need to worry ourselves about it at this time.” Al responded by inviting the panelist to come with him to City Hall and seek to convince city government that it doesn't need a Fire Department since it's an established fact that all fires will eventually go out!

A Global Tribute to Al Bartlett
Some blog followers might be interested in a recent post “A Global Tribute to Al Bartlett” [Hake (2013)]. The abstract reads:
********************************************
ABSTRACT: On 23 July 2013 Al Bartlett, in a post “My Cancer,” to the discussion list Physoc wrote that his non-Hodgkins Lymphoma, previously dormant, has returned such that doctors had given him “30 days, plus or minus.”
A discussion list subscriber “S” suggested to me that:
(a) as a global tribute to Bartlett, people be invited to view his famous 8 part You Tube lecture series “Arithmetic, Population, and Energy” at http://bit.ly/1e6wXiy (aptly tabbed “The Most Important Video You'll Ever See”; and
(b) the goal should be to increase the total number of views for the series from its present 9.19 million to at least 10 million.
For information on Al Bartlett and his work see (a) Bartlett’s website http://www.AlBartlett.ORG/ with its extensive collection of his articles, presentations, and interviews; and (b) the Wikipedia entry http://bit.ly/19jfGEU.
Congratulations to Al Bartlett for his indefatigable concentration on human overpopulation http://bit.ly/193LdIx, the overriding threat to life on Planet Earth.
I hope that many of you will now click on http://bit.ly/1e6wXiy so at to view Part 1 of Al’s masterful explanation of exponential growth.

Sad News About Al Bartlett
ABSTRACT: In a disturbing discussion-list post, Al Bartlett http://bit.ly/19jfGEU wrote that his non-Hodgkins Lymphoma, previously dormant, has returned such that doctors give him “30 days, plus or minus.” As a tribute, it may be appropriate to publicize one of Al’s latest attempts to emphasize the crucial but under-appreciated importance of overpopulation.
In his pungent Population Press letter “Close the Fire Department!” soon to be online at http://populationpress.org/, Al describes his experience at a recent AAAS symposium on sustainability where a panelist, in answer to his question as to why the obvious benefits of reducing our present overpopulation were never mentioned, explained that “United Nations figures show that the growth rate of world population is declining and world population growth is expected to stop on its own later in the century. So the population is under control and there is no need to worry ourselves about it at this time.”
Al responded by inviting the panelist to come with him to City Hall and seek to convince city government that it doesn’t need a Fire Department since it's an established fact that all fires will eventually go out!

Would a Carbon Tax Alone Save Life on Planet Earth? Probably Not: Overpopulation Must Also Be Addressed
Some blog followers might be interested in a recent post “Would a Carbon Tax Alone Save Life on Planet Earth? Probably Not: Overpopulation Must Also Be Addressed” [Hake (2013)]. The abstract reads:
********************************************
ABSTRACT (CAPS in quotes are mine): As I pointed out in a post “Would a Carbon Tax Save Life on Planet Earth?” [Hake (2013a)] at http://yhoo.it/16ECfUn, Hansen & Romm (2013) at http://bit.ly/12djtSf wrote:
“We must have a simple, honest, across-the-board carbon fee COLLECTED FROM THE FOSSIL FUEL COMPANIES AT THE SMALL NUMBER OF DOMESTIC MINES AND PORTS OF ENTRY. All of that money should be distributed to the public -100 percent of it - with equal amounts going to all legal residents.”
Art Hobson (2013a) in an OpEd “Our planet passes a climate benchmark” at http://bit.ly/19tBwGD made a similar point but did not indicate, as did Hansen & Romm, that the carbon fee should be “collected from the fossil fuel companies at the small number of domestic mines and ports of entry.”
Al Bartlett (2013a) responded at http://bit.ly/10loNjf to Hobson's OpEd thusly:
“Here I want to comment on the FIRST OF TWO OMISSIONS in your otherwise excellent and comprehensive presentation. . . . . The ‘stop emissions’ is right on but unrealistic. As long as there are humans on earth, emissions of CO2 will continue at some level. It seems to me to be more realistic to say that: ‘We must embark on a long-term program of continually reducing the annual number of tons per year of greenhouse gases that are released world-wide into the Earth's atmosphere.’ . . . . [To do this] we have to STOP GLOBAL POPULATION GROWTH AND THEN REDUCE THE SIZE OF THE GLOBAL POPULATION TO SOME "SUSTAINABLE" LEVEL. And in a later post Bartlett (2013b) at http://bit.ly/11Og32G stated: “You did state that the solution is to put a tax on carbon. . . . . . The next question that needs to be addressed is: Given the real world in which we live, WHAT IS THE PROBABILITY THAT ON ANY USEFUL TIME SCALE WE CAN ACHIEVE THE GOAL . . . .. OF STOPPING CARBON EMISSIONS BY MEANS OF . . . . . . .PUTTING A TAX ON CARBON?”
Bartlett (2013c) discussed the SECOND OMISSION in a post “Exporting U.S. Fossil Fuels” at http://bit.ly/14sPuBM, stating: “Art and most of the environmentalists who strongly advocate the reduction of U.S. carbon emissions omit one important point. The U.S. exports a significant fraction of the coal that it mines. Thus U.S. coal is burned in other countries where it makes about the same contribution to global warming as it would have if it had been burned in the U.S.”
Hobson (2013a) may have “missed a point,” but Hansen & Romm (2013) did not!
As indicated above they, unlike Hobson, specified that “the carbon fee should be collected from the fossil fuel companies AT THE SMALL NUMBER OF DOMESTIC MINES and ports of entry.” Thus Hansen & Romm's carbon tax would discourage coal mining in the U.S. regardless of whether or not U.S. coal is shipped out of the U.S.
Hobson, in a response at http://bit.ly/124gGEU appeared to be unaware of Hansen & Romm (2013) and failed to make the above argument. But Hobson agreed with Bartlett that THE OVERPOPULATION PROBLEM NEEDS TO BE ADDRESSED SIMULTANEOUSLY WITH THE IMPOSITION OF A CARBON TAX. I also agree with Bartlett - see e.g. “L.A. Times Population Report: Beyond 7 Billion - Fighting the Last War?” [Hake (2012)] online on the OPEN! AERA-L archives at http://bit.ly/TeOpJj.

The Second Greatest Shortcoming of the Human Race
Some blog followers might be interested in a recent post “The Second Greatest Shortcoming of the Human Race” [Hake (2012c)]. The abstract reads:
*********************************************
ABSTRACT: Among the “Twenty-eight Quotes Relevant to Overpopulation” in my post “L.A. Times Population Report: Beyond 7 Billion - Fighting the Last War?” [Hake (2012b)] at http://bit.ly/TeOpJj is one by biologist Joel Cohen from his NYT piece “Seven Billion” [Cohen (2011)] at http://nyti.ms/SU6gFM.
Cohen, in a masterful online talk “You are 25 100-Watt Light Bulbs, Burning All Day” at http://bit.ly/VI86rj stated that: “If you have 3 people in a room and it gets warm, it’s because they’re generating 300 watts of heat – it’s like having a 300 watt light bulb going on. If you multiply 100 watts by 6.8 billion, the number of people on the planet, you find that the whole power generation of the human species is about 0.68 terawatts - a terawatt is a lot of watts: there's kilowatts, megawatts, gigawatts, and terawatts - so that's a lot!" . . . . .[[i.e., it's 10^3, 10^6, 10^9, and 10^12 watts]]. . . . .
According to Al Bartlett (2004): “The greatest shortcoming of the human race is our inability to understand the exponential function.” I would propose a corollary: The second greatest shortcoming of the human race is our inability to understand the meaning of large numbers. See e.g. the You Tube video “Powers of Ten” at http://bit.ly/T0UyKM from the Eames Office.

Finnishing Touches
Some blog followers might be interested in a recent discussion-list post “Finnishing Touches” [Hake (2012)].
The abstract reads:
****************************************************
ABSTRACT: There have been several recent posts regarding the evidently exemplary Finnish educational system on the discussion lists Physoc at http://bit.ly/JjCbfH and Math-Teach at http://bit.ly/IJwwwf.

The Jevons Paradox
Some blog followers may be interested in a recent discussion-list post of the above title [Hake (2009). The abstract reads:
ABSTRACT: In response to Bartlett's (2004) article "Thoughts on Long-Term Energy Supplies: Scientists and the Silent Lie,” David Goldstein (2004) wrote:
“Enlightened energy efficiency policy can have much greater effects on the problems addressed in those articles than any of the solutions or scenarios that the authors presented . . . .[e.g., stopping population growth as recommended by Bartlett]. . . . .”
But to what extent, if any, is Goldstein's claim invalidated by “Jevons Paradox” (JP): “TECHNOLOGICAL PROGRESS THAT INCREASES THE EFFICIENCY WITH WHICH A RESOURCE IS USED, TENDS TO INCREASE (RATHER THAN DECREASE) THE RATE OF CONSUMPTION OF THAT RESOURCE”?
Jeff Dardozzi (2009), in his Population Press article on “Jevons Paradox” (JP) states that the comprehensive review Jevons Paradox: The Myth of Resource Efficiency Improvements [Polimeni et al. (2007, 2009)] “clearly supports the proposition that [JP] is present in the US, Europe, and most other economies and that strategies to increase energy efficiency in themselves will do little to improve the energy situation or the ecological crisis.”
On the other hand, Steve Sorrell (2007) in his comprehensive report The Rebound Effect (another name for JP) is somewhat less certain about the influence of JP, writing:
“Rebound effects are very difficult to quantify, and their size and importance under different circumstances is hotly disputed. Also, rebound effects operate through a variety of different mechanisms and lack of clarity about these has led to persistent confusion. In general, rebound effects have been neglected when assessing the potential impact of energy efficiency policies. A key conclusion of this report is that rebound effects are of sufficient importance to merit explicit treatment. Failure to take account of rebound effects could contribute to shortfalls in the achievement of energy and climate policy goals.”
Neither Dardozzi nor Sorrell consider Bartlett's (2004) recommendation to stop population growth as a solution to environmental problems - see e.g., "The Elephant in the Room: Overpopulation" [Hake (2009)].

Is Global Warming a Point of View or a Scientific Fact?
Some blog readers might be interested in a recent post "Is Global Warming really a one-sided point of view or a scientific fact? #2" [Hake (2009)]. The abstract reads:
*********************************************
Bob Fuller, in his PHYSOC post of 11 March 2009, asked: "Is Global Warming really a one-sided point of view or a scientific fact?" I doubt that any scientifically literate person would call global warming a scientific "fact," but the scientific research consensus is that anthropogenic global warming: (a) does indeed exist [IPCC (2007a)], and (b) poses a threat to life on planet Earth [IPCC (2007b)]. Rick Tarara responded that " 'Global Warming' has become a semi-religious doctrine with all kinds of 'facts' of which only some are scientific." Can Tarara pinpoint any "non-scientific facts" in the IPCC reports? In any case, the generally ignored gorilla in the living room is GLOBAL OVERPOPULATION as pointed out by e.g., Al Bartlett (2008), Elmer Eisner (1999, 2009), and Chris Hedges (2009).
