the garden of limited delights.....

The year 2022 was a year of great transformation and great difficulty. To assess what lies ahead in the coming year, we might start with the fact that 2022 was the 50th anniversary of the publication of the 1972 study The Limits to Growth. It was not a prophecy, but an analysis of current trends. It said that, if nothing changed, we could expect the beginning of an irreversible decline of the world economy in the first decades of the 21st century. The result of the combined effect of natural resource depletion and pollution.


2022 has been a difficult year for climate and energy. But there is still some hope

These are phenomena that occur over a multi-decade span, but the events of 2022 are in line with the trajectory already outlined 50 years ago. Today, the "World System" looks like one of those old cars that loses parts all over the place, consumes fuel like a truck, and pollutes like a coal-fired power plant. In addition, the mechanics not only do not know how to fix it, but they spend their time fighting each other.

We are in trouble on all fronts, first and foremost with fossil fuels. After the Covid-19 crisis of 2020, production showed some recovery, but only a partial one. As for natural gas, Europeans had become accustomed to cheap Russian gas, and this year they got a nasty surprise. Replacing Russian gas will not be easy, and surely the costs of liquefied natural gas are much higher. Not to mention the costs of the infrastructure needed to handle it. And let's say nothing about coal, which is expensive, impractical, and polluting. As for nuclear power, the costs are truly out of this world. It is discussed seriously only where dictatorial governments can afford to embark on expensive and uncertain ventures.

Then there is agriculture, for which fossil fuels are needed for fertilizer and all production operations. At present, the world's agricultural production is fairly stable, but prices are rising everywhere. This is putting the poorest in dire straits. According to FAO data, we are close to having one billion hungry people, and the numbers are growing. In parallel, the growth of the world population has seen a remarkable slowdown. Globally, it is still growing but, if current trends continue, in a few years we may see the beginning of an irreversible decline. On this point, The Limits to Growth was even too optimistic, proposing that the human population could continue growing despite the economic downturn.

About climate, The Limits to Growth saw climate change (part of the general pollution problem) playing a major role only after the beginning of the collapse of the economic system. It may be that, even in this area, the analysis was correct. For the time being, climate change caused regional disasters, rather than global catastrophes. That does not mean we can ignore the problem. The concentration of greenhouse gases in the atmosphere continues to increase and, with it, the earth's temperature. At the same time, no one seems to care about doing anything serious about it anymore, as seen with this year's Cop27.

In short, we are in bad shape. It certainly seems that The Limits to Growth was even more prophetic than its creators themselves expected.

But there are also positive findings that the 50-year-old study could not account for. One is the discovery that the Earth's ecosystem can have an important cooling effect on climate. Not that this will get us off the hook but, if we treat both forests and marine ecosystems better, we can do something good to reduce the effects of greenhouse gases. Another positive factor is the disruptive growth of renewable energy, which today has such low prices that it has no competitors.

If we can get a few decades of peace, perhaps even just one or two, we can expect solar and wind power to replace most fossil fuel energy production. By coupling renewables with higher efficiency of use, we could greatly reduce the problems of both energy availability and emissions.

Can we do it? Maybe we can. And if we work at it, the most pessimistic scenarios of the Limits to Growth will not come true. So happy new year to all!




Some examples of comments (translated from Italian)


From "Diomedes01" (insults)


The usual idiocies of the end of the year! The author is not an ecologist but an anti-nuclear and is willing to write baloney. The IEA wrote that the most economical energy ever is nuclear energy in any way you count! Instead the author says it is the most expensive when the most expensive are renewables that are made competitive by excluding from costs more or less everything! At the end of the day for the author better fossil and gas than nuclear and we talk about green transition! Ha ha ha.


From "Cortisol0" (nearly completely incomprehensible)


... If we are to have any hope people like you must be relieved of the social role you have, as you of how to solve this crisis from innate human behaviors incompatible with having developed science and technology that combined in tools=machines allow you to release and apply monstrous amounts of energy modifying both the natural energy flow, and the ecosystem, you will never admit it, as it is to develop precisely science and technology claiming endless growth, that the current environmental disaster is being produced and it is only possible with your PRIMARY contribution and denying that it is the fault of this combined conjugate because you are the most guilty of all and once it emerged you would be immediately prosecuted popularly for it and your career and life would be irremediably ruined, while the state and its power demand more and more science and power for weapons and social control, so you pretend to seek a solution when the solution as the initial act is to eliminate this dynamic you are part of with the state.


From "MarcoMx" (good understanding of the matter)


"One is the discovery that the Earth's ecosystem can have an important cooling effect on climate." I'll bet a coffee on that. The planet will not watch unresponsive to our stupidity, it will find a way to cool itself, plants and greenery we are late in defending will grow them themselves. If, however, in the equation we were able to bring the war factor, including armaments and related costs, to zero, or almost zero, the equation would become solvable without much difficulty. We would have much more resources for everything, hunger, energy transition, and pollution. By the way, the popularizers of the climate crisis almost never talk about the burden of weapons and wars (to think the worst...). But one only has to look at the figures to see that it is decisive, over $2 TRILLION each year.  If we fail to do this, well then all the consequent problems we deserve, including eventual extinction. In that case, we would be left with billions of cell phones full of the latest selfies ... the aliens who find them after thousands of years will come to the inevitable conclusion, "What a cocksucker civilization."









energy budget.....

A defunct American satellite is expected to fall out of the sky this weekend, but it most likely won’t hurt anybody, the US space agency NASA revealed on Friday, stressing the odds of debris actually harming anyone were “very low,” at approximately 1 in 9,400. 

The 38-year-old, 5,400-pound (2,449 kg) Earth Radiation Budget Satellite is expected to reenter Earth’s atmosphere on Sunday night around 6:40pm Eastern Time, plus or minus 17 hours, according to the Defense Department. While most of it is expected to burn up upon reentry, some parts may survive the fall. 

Aerospace Corp., a space-focused research and development firm, predicts a Monday morning landing for the debris, which will cross Africa, Asia, the Middle East, and the western areas of North and South America.

The ERBS was launched in 1984 from Space Shuttle Challenger as one of three satellites comprising the Earth Radiation Budget Experiment mission. It was released into orbit by Sally Ride, the first American woman in space. While its lifespan was only supposed to be two years, it continued to take measurements until 2005.  

The satellite was outfitted to measure the earth’s “energy budget,” the balance between how much of the sun’s energy the planet absorbs and how much it radiates, and to measure the amount of ozone, water vapor, nitrogen dioxide, and aerosols in the stratosphere. Its stratospheric measurement instrument, known as Stratospheric Aerosol and Gas Experiment II, is credited with confirming the thinning of the ozone layer, which absorbs most of the sun’s ultraviolet radiation.  

Neither NASA nor the Defense Department explained why the satellite fell out of orbit. While satellites occasionally collide with each other, this is supposedly rare. However, Earth’s orbit is becoming increasingly crowded with thousands of private-sector satellites from Starlink and other wireless internet providers, so much so that astronomers are concerned that the amount of light they reflect may soon make it impossible to see into space and are calling for a moratorium on their launch.
