to deny the evidence. Regrettably, the climate crisis is not exactly a matter that interests the great economic powers, whose concern is with the greatest profit possible at minimal cost and in the shortest amount of time. 14. I feel obliged to make these clarifications, which may appear obvious, because of certain dismissive and scarcely reasonable opinions that I encounter, even within the Catholic Church. Yet we can no longer doubt that the reason for the unusual rapidity of these dangerous changes is a fact that cannot be concealed: the enormous novelties that have to do with unchecked human intervention on nature in the past two centuries. Events of natural origin that usually cause warming, such as volcanic eruptions and others, are insufficient to explain the proportion and speed of the changes of recent decades. [11] The change in average surface temperatures cannot be explained except as the result of the increase of greenhouse gases. Damages and risks 15. Some effects of the climate crisis are already irreversible, at least for several hundred years, such as the increase in the global temperature of the oceans, their acidification and the decrease of oxygen. Ocean waters have a thermal inertia and centuries are needed to normalize their temperature and salinity, which affects the survival of many species. This is one of the many signs that the other creatures of this world have stopped being our companions along the way and have become instead our victims. 16. The same can be said about the decrease in the continental ice sheets. The melting of the poles will not be able to be reversed for hundreds of years. As for the climate, there are factors that have persisted for long periods of time, independent of the events that may have triggered them. For this reason, we are now unable to halt the enormous damage we have caused. We barely have time to prevent even more tragic damage. 17. Certain apocalyptic diagnoses may well appear scarcely reasonable or insufficiently grounded. This should not lead us to ignore the real possibility that we are approaching a critical point. Small changes can cause greater ones, unforeseen and perhaps already irreversible, due to factors of inertia. This would end up precipitating a cascade of events having a snowball effect. In such cases, it is always too late, since no intervention will be able to halt a process once begun. There is no turning back. We cannot state with certainty that all this is going to happen, based on present conditions. But it is certain that it continues to be a possibility, if we take into account phenomena already in motion that “sensitize” the climate, like the reduction of ice sheets, changes in ocean currents, deforestation in tropical rainforests and the melting of permafrost in Russia, etc. [12] 18. Consequently, a broader perspective is urgently needed, one that can enable us to esteem the marvels of progress, but also to pay serious attention to other effects that were probably unimaginable a century ago. What is being asked of us is nothing other than a certain responsibility for the legacy we will leave behind, once we pass from this world. 19. Finally, we can add that the Covid-19 pandemic brought out the close relation of human life with that of other living beings and with the natural environment. But in a special way, it confirmed that what happens in one part of the world has repercussions on the entire planet. This allows me to reiterate two convictions that I repeat over and over again: “Everything is connected” and “No one is saved alone”. 2. A Growing Technocratic Paradigm 20. In Laudato Si’, I offered a brief resumé of the technocratic paradigm underlying the current process of environmental decay. It is “a certain way of understanding human life and activity [that] has gone awry, to the serious detriment of the world around us”. [13] Deep down, it consists in thinking “as if reality, goodness and truth automatically flow from technological and economic power as such”. [14] As a logical consequence, it then becomes easy “to accept the idea of infinite or unlimited growth, which proves so attractive to economists, financiers and experts in technology”. [15] 21. In recent years, we have been able to confirm this diagnosis, even as we have witnessed a new advance of the above paradigm. Artificial intelligence and the latest technological innovations start with the notion of a human being with no limits, whose abilities and possibilities can be infinitely expanded thanks to technology. In this way, the technocratic paradigm monstrously feeds upon itself. Regrettably, the climate crisis is not exactly a matter that interests the great economic powers, whose concern is with the greatest profit possible at minimal cost and in the shortest amount of time.
