“Humanity at risk:” climate scientist Schellnhuber speaks at the Vatican

Press Release by the Potsdam Institute for Climate Impact Research


Pope Francis’ much anticipated encyclical “Laudato Si” on inequality and the environment mirrors not only religious insights but also the findings of climate science. “Not the poor but the wealthy are putting our planet, and ultimately humanity, at risk,” said Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research (PIK), at the presentation of the encyclical in the Vatican today. “Those who profited least from the exploitation of fossil fuels and contributed least to greenhouse-gas emissions are hit hardest by global warming impacts, unless we strongly reduce emissions.” Schellnhuber is the only scientist who has been invited to speak, alongside Cardinal Peter Turkson.

In the run-up to the encyclical, Schellnhuber participated in a number of workshops organized by the highly renowned Pontifical Academy of Sciences, which made him its member on Wednesday. The document now issued by the leader of more than one billion Catholics around the world is expected to be an important signal on the road to a global agreement on emissions reductions and eventually a full decarbonization of the world economy which will be negotiated by governments at the world climate summit in Paris later this year.

“The atmosphere, heaven above us all, is a global common – yet it is used as a waste-dump for greenhouse gases by the few,” says Ottmar Edenhofer, chief economist of PIK and director of the Mercator Research Institute on Global Commons and Climate Change. “The Pope is making history in highlighting this. If we want to avoid dangerous climate change, we have to restrict the use of the atmosphere by putting a price on CO2 emissions. This would generate revenues which could be used to improve access to clean water or education, especially for the poor.”

Along with other international experts, Edenhofer has been consulted by the Vatican in the run-up to the encyclical. He was joint leader of a recent project on climate justice and development, which resulted in a number of conferences at the Vatican. On the evening of 18 June, he will discuss the encyclical in Berlin at an event hosted by the Catholic Academy and the Deutsche Bischofs-Konferenz. On 1 July, he will debate the Pope’s messages with Cardinal Turkson and author Naomi Klein (“Capitalism versus Climate”) in Rome.

Common Ground

The Papal Encyclical, Science and the Protection of Planet Earth

Hans Joachim Schellnhuber
Potsdam Institute for Climate Impact Research, Germany; Santa Fe Institute for Complex Systems Research, USA

Laudato si’, the Papal Encyclical[1], is compiled at a crucial moment in the history of humanity: today.

We are faced with the great challenge of limiting global warming to below 2°C while fostering development for the poorest. But we are also experiencing a special window of opportunity because the knowledge about the Earth system has never been greater. Moreover, we have the technical and economic solutions at hand to overcome the challenges we are confronted with.

The urgency to act on these pressing issues that is expressed in the Encyclical mirrors the scientific findings which have accumulated into an overwhelming body of evidence. The science is clear: global warming is driven by greenhouse-gas emissions which are the result of burning fossil fuels. If we fail to strongly reduce these emissions and to bend the warming curve, we, our neighbors and children will be exposed to intolerable risks. The scientific consensus as represented by the Intergovernmental Panel on Climate Change (IPCC) has been continuously reaffirmed by the most eminent scientific academies, including the Pontifical Academy of Sciences and the Pontifical Academy of Social Sciences which have congregated several times over the past years to address the topics of climate change and global sustainability ([2]–[5]). As any further delay to mitigation measures may jeopardize climate stability and thus our future, it is time to form alliances, find common ground and act together as humankind — but also to take on individual responsibility and change what is in our power to change.

What we have done

The large-scale production of fossil fuel energy which was initiated by the Industrial Revolution and accelerated in the 20thcentury has led to great human development – for a minority. For the very few, it has even generated extreme wealth. On the other side of this development stand the poor and the poorest of the poor. The structural violence of this development predetermines their lives. Sources of fossil fuel energy are private goods, owned by corporations or controlled by governments. Access to energy thus largely depends on the financial resources of the individual. It follows that the deployment of fossil fuel energy and the connected technological advances have led to unprecedented disparities and to wasteful over-usage of resources. The carbon history of humankind is one of exploitation.


Figure 1:
Distribution of global carbon emissions over the world population (grouped in countries and ranked by their wealth). The left part of the curve is “flat”, indicating that the bottom billion contributes virtually nothing to global warming. Also, the lower income groups contribute little to global emissions on average. The right part of the curve is “steep”, indicating how much more the lifestyle of the average individual in rich countries contributes to the total global problem.
Data sources: CDIAC for emissions and Penn World Tables 8.0 for GDP and population. Not for all countries was the necessary data available, hence the difference to the actual world population number of more than seven billion people.

But not only were the poor excluded from participating in human progress, now they are forced to cope with the dreadful byproduct: climate change. This constitutes an unacceptable double- inequality: the poor are responsible for a tiny share of global emissions (Figure 1), yet they have to bear the greatest consequences. Contrary to what some have claimed, it is not the mass of poor people that destroys the planet, but the consumption of the rich. Global warming is the consequence of this development of a few and will affect everyone, but brings devastation especially to the weakest in society. As has been pointed out in the Encyclical, it is not possible to address climate change and poverty consecutively, in either order. It is indispensable to confront them simultaneously, as human development is deeply intertwined with the services the Earth provides. If these services are under threat through manmade environmental destruction, the poor will be the first to suffer. They live in exposed areas and have no resources to adapt to a changing climate. Furthermore, some climate impacts will disproportionately affect many of the developing countries.

Presently, the disparities are engrained so deeply that the poor remain voiceless, well-aware of the changes to their environment, but without any knowledge about the underlying causes. They are continuously kept from forming an opinion on climate change because they lack a formal education, yet their need for a life of dignity has been repeatedly misused as an excuse for inaction on climate


change. Hitherto, dignity has remained impossible to attain for the many who live in their own and foreign waste, without access to clean water, exposed to environmental hazards and without the power to shape their own future. The unnecessary hardship the poor have had to experience in a world of abundance can no longer be accepted.

Already, we have not only violated the moral boundaries of our global civil society, but are also leaving the safe operating space of our planet by crossing planetary guardrails [6]. The continuation on this development pathway will not bring prosperity for all, but may end in disaster for most. But it is not an inevitable fate to which humanity has to succumb. As climate change is human-made, it is also in our hands to turn the trend around. Although the Earth system is characterized by great complexities and further research is needed in many areas, the scientific knowledge on climate change impacts is already so profound that it will be impossible to refer to ignorance as a justification for our inaction.

What we have learned

“If the Lord Almighty had consulted me before embarking on the Creation, I would have recommended something simpler” stated Alonso X of Castile in the 13th century. Were this advice taken, we would have been deprived of the exquisite joy that lies in the admiration of the complexity surrounding us – nature itself. Even the most abstract-minded mathematician recognizes the awe- provoking mystery behind the fact that a very simple-looking equation can wonderfully unfold into a beautiful picture of intricacy. The Earth’s climate (in keen competition with the human brain) constitutes perhaps one of the most breathtaking manifestations of this complexity [1, No.20]. We live in an age that grants us the privilege of building on centuries of tradition in natural sciences fueled by human curiosity – this enables us more than ever before to assess the causes of climatic change.

I have had the honor to elaborate on that subject in a contribution to a workshop of the Pontifical Academies of Sciences Sustainable Humanity, Sustainable Nature: Our Responsibility last year [7]. It states that “The climate system is a most delicate fabric of interwoven planetary components (such as the atmosphere, the oceans, the cryosphere, the soils, and the ecosystems) that interact through intricate physical, chemical, geological and biological processes (such as advection, upwelling, sedimentation, oxidization, photosynthesis, and evapotranspiration). […] We eventually become aware of the fact that even slightly pulling one single string might have the potential to tear apart the entire fabric.“

This fabric constitutes the parachute for our daily flight in the environment surrounding us, shaken by the mighty forces of nature – and yet a small, privileged group of mankind has been pulling strings ever more strongly since the start of the Industrial Revolution in the 18th century. And as a result, we are already starting to tailspin. For instance, after a “decade of weather extremes” [8] it is now clear that local heat records happen about five times more often than they would in an unchanged climate – that is with an intact parachute [9]. At the same time, although still too far away to be directly visible to most of us (but not to all!), major turbulence is approaching inexorably: almost 20 cm of global mean sea-level rise since 1880, for example, is starting to impact entire societies, washing away the ground they live on or degrading the soil on which they grow their food through salt-water intrusion.


Sea-level rise distinctly illustrates many dilemmas often involved also with other climate change impacts. Rising gauges, for example, are on the one hand caused by the expansion of sea water as it warms, on the other hand by the extra amount of water in our ocean basins stemming from melting glaciers and ice caps. Since most of the Earth’s ice – inherited from many ice ages over countless millennia – is located near the poles on Greenland and the Antarctic continent, its loss by melting reduces the gravitational pull and sets the water free to float more towards the Equator. This is the region on the globe where most of those people are living who do not have the means to purchase reserve parachutes in the form of uphill estates. Another dilemma lies in the long time span between cause and effect – the already damaged fabric will silently but inexorably unravel more and more until the consequences can no longer be ignored. Ice flow changes that are happening now, for instance, in a large ice basin in West Antarctica ([10], [11]) seem to have been triggered by warm ocean waters bathing the floating tongues of the glaciers. But the resulting speed-up of the ice flow – once initiated – can likely not be halted due to nonlinearities in the underlying dynamics. This means that ultimately about 1.2 meters of sea-level rise – in addition to all the anticipated contributions stemming from human interference with the climate system – have to be expected from that single source over the centuries to come.

The West Antarctic ice sheet is – due to the mentioned nonlinearity – a classic example of a tipping element in the Earth System [12]. But there are many more: from the ice sheets and glaciers, to permafrost in the vastness of Siberia and northern North America, to monsoon systems, the Jet Stream and the El Niño-Southern Oscillation pattern, and to biological systems like coral reefs or the Amazon rainforest. What they all have in common is that fundamental changes of state, caused by a relatively small external disturbance, are possible due to the complexity of the associated nonlinear system. Although the respective dynamics of those elements is beginning to be better understood, our ability as human beings to intuitively grasp nonlinearities is surprisingly limited: in our everyday experience, cause and effect are usually closely connected in time, space and extent. This, however, is not the case with the tipping elements: Climate change, caused by this tiny molecule of CO2, can trigger sudden, irreversible and large-scale disruptions in the above-named interwoven physical and ecological systems. It is therefore of utmost importance for the scientific community to clearly communicate the risks involved with altering our climate – crossing certain thresholds may turn tiny holes in the fabric into long, ever increasing ladders.

The visualization of those risks in Figure 2 aims at making these sometimes dry scientific results come to life: it illustrates a crucial reasoning behind the well-known 2°C guardrail. While for many millennia, human civilization has had the privilege to relish a largely stable Earth temperature (in blue), we are now on track to abandon this climate paradise, as can be seen by the sharp increase in temperature (in black). Depending on the choices we make today, in our future we may follow the green path, respecting the 2°C guardrail, or – if we continue with business as usual – greenhouse gas emissions will lead us along the red path, past 4°C by the end of this century and with even higher warming levels in store after that.


Figure 2:
Global-mean surface temperature evolution from the Last Glacial maximum through the Holocene, based on paleoclimatic proxy data ([13], [14]) (light gray), instrumental measurements since 1750 AD (HadCRUT data, black) and different global warming scenarios for the future (see [15] for the latter). Threshold ranges for crossing various tipping points where major subsystems of the climate system are destabilized have been added from refs. ([15]–[20]).

What difference does it make? This question is often asked with the notion that a doubling of temperature increase would mean a simple doubling in the severity of the consequences. And it reveals the linear thinking that is so natural to most of us. However, this assumption is completely misleading. The complexity of nature gives rise to temperature thresholds which – if crossed – leave the associated tipping element in a fundamentally different state. Those thresholds are visualized in Figure 2 for a number of climatic elements. The coral reefs, for example, are at risk of long-term degradation [16] and the Greenland ice sheet may melt down in the end [20], even if the 2°C guardrail is respected. But the further the temperature rises, the higher is the risk of crossing the tipping point for each element, and the more climatic elements are in danger. The consequences such as the collapse of the “lung of the Earth”, the Amazon rainforest, would be disastrous, not to mention a complete disintegration of the West Antarctic and Greenland ice sheets, associated with about 3.3 and 7 meters of sea-level rise, respectively. As has been addressed also in the Encyclical [1, No. 34], technological advances would not be able to keep up in providing solutions to manage changes of this scale.

The difference between 2 and 4 °C global warming is reflected in these tipping elements. But even without explicitly considering these potential large-scale, non-linear changes, it is indisputable that a 4 °C warmer world has to be avoided ([21]–[23]). For instance, heat extremes, which are virtually absent today and almost certainly never occurred since the rise of human civilization (and not even since the formation of key ecosystems), would become normal in central West Africa following the red path – this is the scenario for business as usual. Such a drastic change would again strike most heavily those who have not eaten from the fruit of fossil fuel burning to any noteworthy extent: the poor.


Figure 3:
Regional distribution of the frequency of extremely hot months (“5σ-months”) in a 4 °C world ( June, July and August between 2080 and 2100). The color coding indicates the percentage of months which are hotter than today by five standard deviations (5σ) – those heat extremes would be virtually absent without climate change. On one end of the color scale is dark blue (0%-10% of all months are hotter by five σ); on the other end dark red (90%-100% of all months are hotter by 5σ). This shows clearly that 5σ-months become the new “climate normal” in the tropical land regions ([24]– [26]).

What we need to do

The long-term perspective illustrated through the tipping thresholds in Figure 2 reveals a far-reaching insight: Although the poor are the first to suffer and will be most fundamentally affected, all of mankind are ultimately reliant on the same parachute, irrespective of the temporary short-term benefits for a handful. This parachute – a stable climate – being destroyed by the few, is our common good. The Encyclical confirms this assessment which scientists and moral philosophers have claimed in the context of climate policy: “The climate is a global commons of all and for all” [1, No. 20]. The atmosphere is a global good because of its limited disposal space for greenhouse gas emissions. Presently, the upper-middle classes worldwide are rapidly depleting this scarce resource by emitting greenhouse gases in vast amounts. In contrast to the limited disposal space in the atmosphere, fossil fuels, especially coal, are abundant. Hence limiting the increase of global mean temperature to 2°C requires confining the amount of carbon still to be released into the atmosphere to 1000 gigatons of CO2 (or less). Whereas restricting the use of the atmosphere as a carbon dump is absolutely necessary to avoid intolerable damage and suffering for the many, it will devalue the assets and the property titles of today’s owners of coal, oil and gas. Almost 80 % of coal has to remain underground in a climate-change mitigation scenario compared to a business-as-usual case. Hence, climate policy implies shifting property rights for using the atmosphere from fossil fuel owners to a novel owner – humankind as a whole [27].

It is understandable that there are claims for compensation for the devaluation of the assets in the fossil fuel sector. However, the devaluation of these assets is by no means an illegitimate expropriation because it serves the common good – the avoidance of catastrophic climate risks. The Encyclical draws attention to the principle of “the social obligation of private property”. This goes back to St. Thomas Aquinas and has been further developed by the social teaching of the Catholic Church, in particular by this Encyclical “Laudato si’” of Pope Francis [1, No. 20, 93-95, 156-158]. It maintains that private property, in general, and in natural resource endowments, in particular, is


ethically justifiable only if it serves the common good. Moreover, the upcoming devaluation of fossil resources could be viewed as an act of ‘creative destruction,’ instigating a new integral industrial revolution that would bring enormous economic opportunities – possibly also to those who have so far not participated in human progress. The transformation of the way we produce our energy may well cause a greater transformation of society as a whole.

International negotiations over national emission reduction goals, national carbon prices or even a global price, implicitly or explicitly allocate rights for use of carbon space in the atmosphere to nation states, firms and consumers. “Laudato si’” does not provide technical guidance on how to allocate user rights for the atmosphere. However, Pope Francis highlights the ethical dimension of the climate problem and provides fundamental principles to be applied for solutions: the preferential option for the poor, inter- and intragenerational justice, common but differentiated responsibility, orientation to the common good. The Encyclical argues for a global governance structure for the whole spectrum of the planetary commons [1, No. 174]. Putting a price on CO2 emissions – either in the form of emissions cap & trade systems like the one in Europe or the one that China plans to set up, or through national CO2 taxes – is an effective instrument to protect the common good.

Figure 4 shows that a mitigation pathway is economically feasible, without significant consumption losses, compared to a business-as-usual scenario. Further, a strong, legally binding target and an adequate CO2 price would provide businesses with more predictable frameworks to operate in – something that even major oil companies recently called for – and give incentives to invest in clean technologies. This would significantly accelerate innovation in the fields of renewable energy production, distribution and storage and at the same time bring down production costs and retail prices. To spur the build-up of new energy systems in the developing world, to support them in their mitigation efforts as well as in adaptation measures to build climate resilience, financial instruments such as the Green Climate Fund are indispensable. Controlling efficient use of the funding for the benefit of the poor of course is a challenge. Yet insurance systems, for instance, which enable subsistence farmers to economically survive climate-related yield failures and other disasters, illustrate how much can already be done today. Moreover, a variety of solutions have emerged from the scientific discourse, including, for example, international monitoring of national emissions reductions or the establishment of a global ‘climate bank’ to manage the emissions allowance.


Figure 4:
“The cost of saving the planet”. The blue mitigation path shows the median reduction of consumption and its uncertainty range as estimated by IPCC, illustrated here relative to a baseline example (red) with 2.3% annual growth. The nearly 8-fold increase in global consumption by the year 2100 in the baseline case is reached 2 years later in the case that includes the median climate mitigation costs. Note that these cost estimates do not consider damages from climate change, which would likely turn out to be a much greater burden than the mitigation costs, nor does it include co- benefits or side effects of mitigation

Technologically, the deployment of clean energy for all is feasible [28]: this energy, in fact, is available in abundance. All we have to do is develop the means to properly harvest it and responsibly manage our consumption. While we have been working decade after decade on developing an incredibly expensive fusion reactor, we are already blessed with one that works perfectly well and is free to all of us: the Sun. Photovoltaics, wind and energy from biomass are ultimately all powered by sunlight. These new technologies could unfold potential in poor countries where no grid exists to distribute electricity produced by centralized power plants and where settlements may be too distantly located from one another to make such a system feasible. Just like the evolving use of mobile phones without the previous establishment of landlines, developing countries could leapfrog the fossil episode and enter the age of decentralized renewable energy production without detour.

The care for our planet therefore does not have to evolve into a tragedy of the commons. It may well turn into a story of a great transformation in which the opportunity was seized to overcome the profound inequalities. These disparities arose from the geological coincidence of regional fossil fuel distribution controlled by the few and the concomitant exploitation. Today, the implications of our actions and the pathways are clear. It is solely a question of what future we choose to believe in and to pursue [29].

    The high priests of Flummery have finally married. Comedy is at such a low ebb it is fitting that these 2 finally got together. Will there still be a collection plate? Not to worry, there will be and more of them too. It was only a matter of time until the new religion merged with the old. At least it keeps all the intolerant hypocrites in one place. It was only natural that the One Government types join their forces for comfort, alarmism and world dominance. ‘End of the World’ threats arouse the requisite feelings of guilt and sin so necessary to a true calling. Pass the collection plate! Anything less than complete devotion to their shared dogma is now officially a sacrilege. I can hardly wait to see the penalties. Good to know burning at the stake will not be one of them. Too much carbon, you see.

    Throughout time, the more primitive amongst us have always viewed the weather as central to our belief system. “Extreme” weather events are seen as punishment from the god(s) for the sins of the tribe. In modern speak this has become the rant against industrialization and capitalism even though both have increased wealth, improved health and living standards worldwide. Google standards in the 1200s, for example, if you doubt the veracity of the statement. Pick an Age, any Age. Life has not improved for everyone nor will it ever if the new religion succeeds in taking away their only sources of heat and power.

    It puzzles me how the Left can support the transfer of wealth from the poor to the rich. I’m speaking of the system of heavily subsidizing wealthy landlords to have wind farms on their land so that the poor can be supplied with one of the most expensive forms of electricity known to man.

    In the end both P&P (Pope and Potsdam) want to transfer wealth from the developed west to the developing world also known as the emerging economies. Please note, neither is giving up their own wealth most especially the Pope who controls vast holdings in land, buildings and art. He got this from the poor people he so cares about. I wonder if he ever thinks about giving it back.

    The World Resources Institute identifies 1,200 coal plants in planning or building stages across 59 countries. India is planning 455 new plants compared to 363 in China. The lower number for China represents a slowdown after a vast building programme in the past decade. The Narcissist in Chief made his deal on reductions with a country that was completing its build out and has no current need for future growth. Brilliant, for the Chinese.

    With economic growth now firmly on the march it is inevitable that China, India and the lesser developed will increasingly account for the majority of global emissions. Still, despite their recent success, there are still hundreds of millions of people in these countries in dire poverty, suffering malnutrition, preventable disease and premature death. P&P will attempt to force these countries to abandon the cheapest available sources of energy while they frivolously attempt to conquer the world and transfer its wealth. While they are at it P&P might as well ask these nations to ignore malnutrition, to perpetuate preventable disease and to increase the number of premature deaths. I guess even Climate Orthodoxy has its price.

    Oh, I know the Paris Conference of wine, canapes and 5 star suites is coming but guess what? The G7 just drove a knife through its heart. Based on all the evidence presented, the G7 were forced to note that for the last 35 years the doom and gloomers have predicted fossil fuels would cause catastrophic global warming, catastrophic pollution or a catastrophic shortage of fossil fuels. If not those things then extreme something or others with lots of catastrophics in between. The reality is that CO2 causes mild, manageable and arguably, for most people, a desirable warming and an increase in plant and crop growth. The further reality is that human technology progressively purifies our endeavours.

    U.S. air pollution has declined radically despite a 25 per cent increase in fossil fuel use. They won’t “run out of fossil fuels” anytime soon. Nor will we. There are many times more potential resources underground now than we have used in the entire history of civilization. There are new technologies like shale and oil sands energy that are turning these resources into the fuels that heat our homes, power our tractors, and run our hospitals. For those interested, they create jobs as well.

    The G7, having international economic responsibilities, naturally questioned the people and institutions whose faulty thinking and methodologies have led to the shocking array of false predictions and exaggerations. They also rightfully became suspect of the obvious bias against fossil fuels.

    The G7 did notice the benefits, however. In the 25 years since 1980 the 7 billion residents of the world have increased their use of coal, oil and natural gas by some 80 per cent. Also during those 25 years, the average life expectancy of these same residents has gone up by 6 years! Every other metric of human well-being has also improved, from income to health care to food supply. Perfect no, but constant and steady improvement all the same.

    Like it or lump it the energy industry powers every other industry. Cheap, plentiful and reliable energy empowers people to use machines and to improve their lives. China and India each increased fossil fuel use fivefold. Hundreds of millions got their first light bulb, their first refrigerator and their first decent-paying job. Restrict energy development and you restrict the development of people. They are not all going to have solar panels, windmills and electric cars. They are also not going to have oodles of other people’s money. That too is reality.

    Germany, a leading member of the G7, is the best story. They have failed to run their country on solar and wind. Their entire solar and wind apparatus is not a productive energy source but an absurd consumer expenditure. We have the same here in Ontario. It delivers a modicum of prestige, guilt alleviation for those who need but no net energy. It is also unreliable.

    In 1985, John Holdren predicted that “carbon dioxide climate-induced famine could kill as many as a billion people” by 2020. He became an Obama Science Advisor. The international disaster database reveals that climate-related deaths are down 98 percent over the past 80 years. I guess the energy that allows us to produce substantial homes, heating, air-conditioning, irrigation, drought-relief and advance warning systems isn’t so bad after all.

    The G7 did declare that after they were all dead, say 2050, the world would need to make illegal the use of up to 70% of today’s fossil fuels. Mind you the population will be about 9 billion then so about half of them will have virtually no energy.
    Some plan.

    P&P will no doubt throw in their hands with the IPCC and the lot in Paris. There they will no doubt join the wildly irrational anti-nuclear movement that opposes the most efficient non-CO2-emitting technology. Works fine here. P&P, the IPCC and all the other delegates will further promote all the same old forms of highly subsidized and unreliable energy on a large scale. These are the very same forms that have proven to be so ruinous on a small scale. There they can all trumpet more outlandish predictions based on the same assumptions that proved false the last time they met. The more things change………………

    The Pope, noted scientist and philosopher that he is, has simply regurgitated the same old anti-capitalist foofrah the church has been dining on for centuries. Meanwhile he protects the vast wealth and holdings of this very same church. No surprises there. He has chosen the perfect mate. Francis has his priests. Schellnhuber has his acolytes. They have more in common than the quest for world domination. They love other people’s money too.

    Sadly, there is a fly in this new fusion of fanatical ointments. The Pope’s encyclical rejects one of the eco-warriors core tenets, indeed a building block of their irresponsible economics. He is against carbon trading. What to do, what to do? Best we all get down on our knees and pray. But to whom, the Pope or Potsdam? Decisions, decisions.
