Researchers at the Center for Climate Systems Research (CCSR), a part of The Earth Institute, have developed a high-resolution map of projected population change for the year 2025.
The innovative map shows a world with large areas of population loss in parts of Eastern Europe and Asia, but significant gains elsewhere.
The work, Mapping the Future, is the result of collaboration between CCSR, Hunter College and Population Action International (PAI) and was released this spring in conjunction with an update of PAI’s Web feature, People in the Balance, investigating the relationship between human population and critical natural resources.
The map indicates that the greatest increases in population density through 2025 are likely to occur in areas of developing countries that are already quite densely populated. In addition, the number of people living within 60 miles of a coastline is expected to increase by 35 percent over 1995 population levels, exposing 2.75 billion people worldwide to the effects of sea level rise and other coastal threats posed by global warming.
The map also projects that much of southern and Eastern Europe and Japan will experience significant and wide-spread population decline. Surprisingly, the map further suggests small areas of projected population decline for many regions in which they might be least expected: sub-Saharan Africa, Central and South America, the Philippines, Nepal, Turkey, Cambodia, Burma and Indonesia — areas that have to date been experiencing rapid-to-modest national population growth.
"By bridging these two areas of demography — mapping and long-range, aggregate projections — we're getting a better idea of where people are likely to live in the future and why," said Stuart Gaffin, associate research scientist at CCSR and lead scientist on the project. "Hopefully, work like ours will play a central role in improving environmental policies around the world and in reducing natural hazard risks faced by the most vulnerable parts of society."
Where most projections show future global population for each of more than 200 countries, Mapping the Future displays the projected population for each of nine million cells distributed across the globe. Known as "downscaling," this new arena of spatial analysis and demography is expected to be of particular interest to conservationists, climate specialists and others who need to know where people will live, and in what numbers, in coming decades and in extremely fine detail. The data may also provide a "best guess" of regional populations that might be most susceptible to natural disasters in the future.
"We already have a pretty good idea of how the population of individual countries is likely to change in coming years," said Gaffin. "This map pushes the frontier on projecting high-resolution, sub-national populations so we can begin to examine how internal population dynamics might play out against other environmental, ecological and socio-economic concerns."
To produce the map, Gaffin and his colleagues extrapolated population changes that occurred between 1990 and 1995 out to 2025 in each grid cell. They selected from two methods to arrive at the best and most likely fit consistent with the UN's "medium variant" projection for each country’s population: one based on a particular cell's changing fractional share of the overall national population and another based on the cell's share of national growth during the 1990s.

Japan Times
Is growth driving us to oblivion?
By STEPHEN HESSE | Apr 22, 2008 | 1491 words, 0 images
Last month, when I wrote a column headlined 'Apocalypse when? Can three experts all be wrong on looming disaster?,' I expected that readers would harangue me for taking up ranks with the pessimists. After all, for every doomster, there seems to be a Pangloss reassuring us that all will be well. Recently in The Japan Times, for example, Ray Kurzweil argued that exponential progress in technology will offer solutions to all our problems before they get the better of us ('Making the world a billion times better'; April 17). Nice to think so, certainly, though at least one scientist I'll introduce later believes that the exponential function, and our failure to understand it, is precisely why we have so many problems. In any case, I was wrong. No one wrote to accuse me of being a prophet of doom; just the opposite happened. Everyone who wrote said the experts Lester Brown, president of the Earth Policy Institute in Washington, British scientist James Lovelock, and Jeffrey Sachs, director of the Earth Institute at Columbia University in New York are not critical enough in their assessments. Several readers in particular, from different corners of the globe, were adamant in their criticism. Each sent me Web site links to check out, and they also stressed that planetary survival hinges on the issue of population. This column will share some of their comments and some of the people and resources they introduced, so thanks to you all, worldwide, in advance. Prof. Eric R. Pianka, a biologist at the University of Texas in Austin, didn't waste any words setting me straight: Hi Steve, You, like almost everybody, miss the point. Treating the symptoms of overpopulation while denying the cause is like driving into a brick wall at top speed. We must get out of this state of total denial and face reality. We must confront the source of ALL our problems: Too Many People. Above all, face reality and THINK. Best wishes, Eric If you're interested in knowing more about Pianka's opinions, research and solutions, see his thought-provoking Web site at: www.zo.utexas.edu/courses/THOC/ Another reader, from Switzerland, sent along his Web site address and some pointed criticisms of all three experts. Dear Mr. Hesse, Yes. All three 'learned experts' are wrong. Mr. Sachs is wrong because he still believes in economic growth and progress on a planet that has finite space and resources. Hardly any economist gets that point right! Mr. Brown is wrong because he believes we can at least maintain our present level of exuberant consumption. One has to sound vaguely optimistic to be taken seriously. Optimism and hope and belief in technology are today's civic duties. And Mr. Lovelock has lost his logic. He is right in saying that many solutions are a scam and a waste of time and effort. But his nuclear solution is tremendously off. Humanity's problem is not that we don't have enough energy, but that we have too much. The vast amounts of cheap, easy fossil energy have allowed humanity to reach the enormous overshoot of the Earth's carrying capacity, in numbers and in consumption per capita. The world's population under business-as-usual scenarios is expected to rise to 8.5 billion by 2050 (it is 6.7 billion now), and nobody knows how all those people can live in terms of either space or resources. Kind regards, Helmut Lubbers I asked Lubbers in a followup e-mail what he thought we should be doing to get humans and the planet back in balance. He replied: Relocalization, elimination of motorized transportation, but for emergency services, slowing down in general, using power when nature provides it, i.e., when the wind blows and the rivers carry water, and elimination of all destructive and useless activities, demechanization, and a return to a very frugal lifestyle. All this will only make sense if people realize that we have far overshot the Earth's carrying capacity, that economic growth means increasing the speed of resource depletion, and that as a logical consequence we have to consciously and democratically contract economic activities and population sizes. So in sum I think we are lost as long as the BAU (business-as-usual) scenario reigns in this world, Lubbers wrote. You can visit Lubbers' Web site, an eclectic compendium, at: ecoglobe.ch/ Meanwhile, a third reader, Peter Salonius, provided the most comprehensive comments and links. Salonius is a soil scientist in Canada and he, too, argues that population is overshooting the planet's carrying capacity, resulting in the degradation of ecosystems that already cannot support present population levels. I have taken the liberty of synthesizing parts of his e-mail with other comments he sent. Hello Stephen Hesse, I do hope you have time to run through the material I present below; it is as far as I have gotten after starting to broaden my attention away from the reductionist soil science that occupied me for about 40 years toward more holistic/systems deliberations. Many keen thinkers have understood that the driver that has enabled our numbers to shoot so far over long-term carrying capacity is the planet's one-time gift of fossil fuels, and this overshoot has resulted in our rampant destruction of the biosphere. The global human population before the start of the Fossil-Fuel Revolution was about 1 billion, while it is now about 6.6 billion and rising. These holistic thinkers suggest that without oil, the Earth will only support about 2-3 billion. The other major factor that has enabled our numbers to shoot so far over long-term carrying capacity is the one-time gift of erodible soils and the vast store of plant nutrients they contained. William Rees and Mathis Wackernagel have developed the Ecological Footprint Analysis and believe that humanity overshot global carrying capacity sometime in the 20th century, while it is more likely that the human family has been in overshoot for the last 10,000 years, and has been sidestepping this overshoot by further forest destruction for agriculture, migration to new areas, global trade, and the fossil-fuel-dependent motive power, fertilizers, insecticides and herbicides that make modern agriculture possible, Salonius wrote. Salonius also included two interesting links, one an easy-to-understand slide show on food production and population, and the other an engaging talk by Dr. Albert Bartlett explaining the so-called exponential function. The slide show, titled 'World Food and Human Population Growth,' explains how increasing food production to feed a growing population spurs even further population growth. An important corollary is that industrial agriculture, which we have embraced to feed the hungry masses, is rapidly degrading soils and destroying forest, marine and freshwater ecosystems. The slide show is the work of Dr. Russell Hopfenberg, a consulting associate at Duke University in North Carolina. You can find it at www.panearth.org The talk by Bartlett, an emeritus Professor of Physics at the University of Colorado, Boulder, explains the so-called exponential function in simple terms. This may not be the sexiest topic, but Bartlett makes a clear and convincing case for why we all need to have a better understanding of exponentiation. His talk is titled 'Arithmetic, Population and Energy.' 'Some of these problems are local, some are national, some are global. They're all tied together. They're tied together by arithmetic, and the arithmetic isn't very difficult,' begins Bartlett. He goes on to explain that we need to understand the function better, because our society's addiction to exponential growth is both untenable and undesirable. Population growth, another exponential threat, is 'the immediate cause of all our resource and environmental crises,' he warns. Bartlett makes his point convincingly, with humor and pithy quotes such as this one from Isaac Asimov: 'Democracy cannot survive overpopulation. Human dignity cannot survive overpopulation. Convenience and decency cannot survive overpopulation. As you put more and more people into the world, the value of life not only declines, it disappears. It doesn't matter if someone dies, the more people there are, the less one individual matters,' said Asimov. Clearly, across the globe, from America to Switzerland to Canada, the fate of our planet and the population threat are very real concerns for Japan Times readers. The consensus is that we need to reverse exponential growth of both the numbers of new people and resource consumption, and we need to start now. As Bartlett notes, this will require educating policy-makers worldwide to the lessons of simple math. 'The greatest shortcoming of the human race is our inability to understand this very simple arithmetic,' he chides good-naturedly. Bartlett ends with a quote from the Rev. Martin Luther King on overpopulation: 'What is lacking is not sufficient knowledge of the solution, but universal consciousness of the gravity of the problem and the education of the billions who are its victims.' So, while corporations and politicians continue to reassure us that we can squeeze more energy, more food, and more resources from the planet's shrinking reserves, perhaps the best, real solution is to give women and families worldwide the education and support they need to raise just one or two children well rather than three or more willy-nilly, at the planet's and all children's peril.

Dear Dr. L. B.,
I am imagining that your questions are rhetorical ones.
You ask,
“Why are politicians and skeptics so willing to risk their future and everyone else’s future on blindly clinging to a course of action that has a high probability of leading to a seriously crippled future? If you even suspect that global warming represents a serious risk to your survival (and we have far more than suspicion these days), why wouldn’t you do everything protect and conserve your planet?â€
It would please me to hear from others; but from my humble perspective the “answers†to your questions are all-too-obvious.
First, the leaders in my generation of elders wish to live without having to accept limits to growth of seemingly endless economic globalization, of increasing per capita consumption and skyrocketing human population numbers; our desires are evidently insatiable. We choose to believe anything that is politically convenient, economically expedient and socially agreeable; our way of life is not negotiable. We dare anyone to question our values or behaviors.
We religiously promote our shared fantasies of endless economic growth and soon to be unsustainable overconsumption, overproduction oand overpopulation activities, and in so doing deny that Earth has limited resources upon which the survival of life as we know it depends.
Second, my not-so-great generation appears to be doing a disservice to everything and everyone but ourselves. We are the “what’s in it for me?†generation. We demonstrate precious little regard for the maintenance of the integrity of Earth; shallow willingness to actually protect the environment from crippling degradation; lack of serious consideration for the preservation of biodiversity, wilderness, and a good enough future for our children and coming generations; and no appreciation of the understanding that we are no more or less than human beings with “feet of clay.â€
We live in a soon to be unsustainable way in our planetary home and are proud of it, thank you very much. Certainly, we will “have our cake and eat it, too.†We will fly around in thousands of private jets and live in McMansions, go to our secret clubs and distant hideouts, and risk nothing of value to us. Please do not bother us with the problems of the world. We choose not to hear, see or speak of them. We are the economic powerbrokers, their bought-and-paid-for politicians and the many minions in the mass media. We hold the much of the wealth and the power it purchases. If left to our own devices, we will continue in the exercise of our ‘rights’ to ravenously consume Earth’s limited resources; to expand economic globalization unto every corner of our natural world and, guess what, beyond; to encourage the unbridled growth of the human species so that where there are now 6+ billion people, by 2050 we will have 9+ billion members of the human community and, guess what, even more people, perhaps billions more in the distant future, if that is what we desire.
We are the reigning, self-proclaimed masters of the universe. We have no regard for human limits or Earth’s limitations, thank you very much. Please understand that we do not want anyone to present us with scientific evidence that we could be living unsustainably in an artificially designed, temporary world of our own making…… a manmade world filling up with distinctly human enterprises which appear the be approaching a point in human history when global consumption, production and propagation activities of the human species become unsustainable on the tiny planet God has blessed us to inhabit….. and not to overwhelm, I suppose.
Third, even our top rank scientists have not found adequate ways of communicating to the family of humanity what people somehow need to hear, see and understand: the reckless dissipation of Earth’s limited resources, the relentless degradation of the planet’s frangible environment, and the approaching destruction of the Earth as a fit place for human habitation by the human species, when taken together, appear to be proceeding at a breakneck pace toward the precipitation of a catastrophic ecological wreckage of some sort unless, of course, the world’s colossal, ever expanding, artificially designed, manmade global economy continues to speed headlong toward the monolithic ‘wall’ called “unsustainability†at which point the runaway economy crashes before Earth’s ecology is collapsed.
Sincerely,
Steve
The unexpected lay-off of Alan Schwartz, CEO of Bear Stearns

A “sub prime†example of how the wealthy are destroying the world we inhabit ???
Buddy, Can You Spare a Billion?
By Dana Milbank
The Washington Post
Friday 04 April 2008
Meet Alan Schwartz, welfare recipient.
As the chief executive of Bear Stearns, he’s getting rather more public assistance than your typical welfare mom - specifically, $30 billion in federal loan guarantees to help J.P. Morgan Chase take over his firm. But then, Schwartz has had rather more than his share of suffering of late.
As his firm collapsed, he was forced to forgo his entire 2007 bonus, leaving his compensation for the past five years at a paltry $141 million, according to Business Week. Things have become so bad that, the Wall Street Journal discovered, Schwartz has had to rent out his 7,850-square-foot home on the ninth green of a suburban New York golf course - leaving the poor fellow with only his 17-room, seven-acre home in Greenwich, his condo in Colorado and the athletic center he built for Duke University.
Schwartz’s tale of woe tugs at the heartstrings all the more because he and his colleagues at Bear Stearns were, he believes, blameless for the bankruptcy of two hedge funds and the subsequent collapse of the 85-year-old investment bank. “I am saddened,†Schwartz told the Senate banking committee yesterday. He was saddened that Bear Stearns was undone by “unfounded rumors and attendant speculation,†despite its impeccable balance sheet.
“Due to the stressed condition of the credit market as a whole and the unprecedented speed at which rumors and speculation travel and echo through the modern financial media environment, the rumors and speculation became a self-fulfilling prophecy,†Schwartz told the senators. “There was, simply put, a run on the bank.â€
Sen. Richard Shelby (R-Ala.) asked the corporate-welfare recipient whether he shares any blame for his indigent circumstances. “Do you believe that your management team has any responsibility for the company’s collapse?â€
Schwartz could think of no missteps - not even his decision to remain at a conference at the Breakers in Palm Beach while his firm was imploding. “I just simply have not been able to come up with anything, even with the benefit of hindsight,†said the blameless chief executive, escorted into the hearing room by superlawyer Robert Bennett.
Fortunately for Schwartz, he had a sympathetic audience in the banking committee, whose members have received more than $20 million in campaign contributions from the securities and investment industry, according to the Center for Responsive Politics. “I want the witnesses to know, and others, that as a bottom-line consideration, I happen to believe that this was the right decision,†Chairman Chris Dodd (D-$5,796,000) said before hearing a single word of testimony.
“You made the right decision,†Sen. Evan Bayh (D-$1,582,000) told the regulators who worked out the loan guarantee.
“The actions had to be done,†agreed Sen. Chuck Schumer (D-$6,162,000).
Only a minority of senators, particularly those with smaller pieces of the campaign-cash pie, dissented. “That is socialism!†railed Sen. Jim Bunning (R-$452,000). “And it must not happen again.â€
To the extent the lawmakers objected to the Bear Stearns bailout, they worried that the Fed’s actions would create a “moral hazard†- an economic term of art - that, as Shelby put it, “encourages firms to take excessive risk based on the expectations that they will reap all the profits while the federal government stands ready to cover any losses if they fail.â€
Shelby’s notion was a curiosity for the senators, who don’t often spend a lot of time worrying about moral hazards. No fewer than five other senators invoked the phrase. “I think the moral hazard was minimized,†Federal Reserve Chairman Ben Bernanke, one of the witnesses, reassured the senators.
No moral hazard, however, would interfere with the lawmakers’ compassion for the beleaguered Schwartz and his fellow witness, J.P. Morgan Chase’s Jamie Dimon, who had given a combined $260,000 in political contributions in recent years - a small part of the $1.7 million their co-workers contributed in this election cycle alone. That’s a sizable handout - but a good investment compared with the $30 billion federal hand-up.
“On behalf of all of us here on this dais, our sympathies go out to your employees,†Dodd told Schwartz after his opening statement. “There’s no adequate way we can express our sorrow to them for what happened. Obviously, shareholders, same sort of feelings, but obviously the employees particularly. It’s a particularly hard blow.â€
Of course, some might consider $30 billion an adequate expression of sympathy, but Dodd was apologetic as he gently probed Schwartz. “You both will have forgotten more in the next 10 minutes than I’ll ever probably understand about all of this,†he told the witnesses, but didn’t the irregular trading at Bear Stearns mean than “more than just rumors†were behind Bear Stearns’s demise?
“You could never get facts out as fast as the rumors,†Schwartz explained. “It looked like there were people that wanted to induce panic.â€
Sen. Bob Menendez (D-N.J.) reminded Schwartz that two of the firm’s funds went bankrupt in 2007. “It caused concern, not only here but on Wall Street,†the senator said. “Did that dramatically alter your behavior?â€
Evidently not. “I’m not sure I understand the question,†Schwartz
Refusing to see what is happening

Something is happening that many too many people appear not to be seeing, I suppose.
Scientific evidence is springing up everywhere that indicates the massive and pernicious impact of the human species on the limited resources of Earth, its frangible ecosystems and life as we know it.
Guided by mountains of carefully and skillfully developed research regarding climate change, top rank scientists like Dr. Rajendra K. Pachauri, Dr. James Hansen, Dr. Hans J. Schellnhuber and Dr. Christopher Rapley issued a Climate Code Red emergency declaration this month to leaders of governments and to the family of humanity proclaiming the necessity for open discussion and action by politicians and economic powerbrokers.
From my humble perspective, many leaders of the global political economy are turning a blind eye to human over-consumption, overproduction and overpopulation activities that can be seen recklessly dissipating the natural resources and dangerously degrading the environs of our planetary home. The Earth is being ravaged; but it appears many leaders are willfully refusing to acknowledge what is happening.
Because the emerging global challenges that could soon be presented to humanity appear to so many fine scientists as human-induced, leaders have responsibilities to assume and duties to perform, ready or not, like them or not.
Perhaps leadership in our time has too often chosen to ignore whatsoever is somehow real in order to believe whatever is politically convenient, economically expedient, socially agreeable, religiously tolerated and culturally prescribed. When something real directly conflicts with what leaders wish to believe, that reality is denied. It appears that too many leaders are content to hold tightly to widely shared and consensually validated specious thinking when it serves their personal interests.
Is humanity once again finding life as we know it dominated by a modern Tower of Babel called economic globalization? That is, has human thinking, judging and willing become so egregiously impaired by our idolatry of the artificially designed, manmade, global political economy that we cannot speak intelligibly about anything else except economic growth and profits without sounding like blithering idiots?

Impending ecological catastrophes or economic disasters
January 27, 2008 by Anonymous, 1 year 22 weeks ago

Humanity has been warned repeatedly about the threat to humanity, to life as we know it, to the viability of recognizably frangible global ecosystems and to the integrity of Earth and its limited resources that could be posed to humankind by the unbridled growth of absolute global human population numbers. Because we want human beings to be fed and to have jobs so they can feed themselves and their families, the growth of human numbers has lead great thinkers and scientists to regularly remind the human community of the impacts of unregulated human propagation, unrestrained consumption and rampantly expanding production activities in our planetary home.
Every possible bias, rhetorical device and "spin" appears to have been employed to deny the mounting evidence of the potential for impending ecological calamities and economic disasters from the near exponential growth of human numbers worldwide. Recently, good science about the way the world works has been systematically discredited; leading elders of the political economy have consciously conspired to mislead the public by misrepresenting the science and by turning climate science into a "political football" of sorts; ideological groups sponsored by super-rich, large-scale corporate 'citizens' have spread uncertainty and confusion in discussions about the nature of the biophysical world in which we live; and controversy has been manufactured where none would have otherwise existed.
The illusion of meaningful debate has been foisted upon the public by leaders who are evidently intent on "poisoning the well" of public discourse by knowingly and selfishly fostering disinformation campaigns for the purpose of enhancing their own financial interests........come what may for our children, coming generations, global biodiversity, the environment, and the Earth as a fit place for human habitation.
The elder guarantors of a good enough future for the children appear to be leading our kids down a "primrose path" along which the children could unexpectedly be confronted with sudden, potentially colossal threats to human and environmental health that appear to be derived from human-driven, converging global challenges such as pernicious impacts of global warming and climate change, pollution of the air, water and land from microscopic particulates and solid waste, and the reckless dissipation of scarce natural resources. All the while, these leading elders remain in denial of the fulminating ecological degradation by willfully declining to acknowledge, much less begin to address, humanity's emerging, human-induced predicament. One day, perhaps sooner rather than later, our children could have extraordinary difficulties responding ably to that with which they could soon come face to face; that is to say, because their leaders have so adamantly refused to acknowlege God's great gift of the good science of biological and physical reality, our kids will not even know what "hit" them, much less why it is happening.
Please note the concerns I am trying to communicate are expressed much better yesterday by Cameron Smith at the following link.
