Semi-permanent El Niño prevailing? Our generation may witness the end of human civilization in the future
El Niño is semi-permanent
If the biggest dilemma facing humanity this century is, it may not be the energy crisis, but the climate Variety. The anomalous phenomena of the global climate in recent years have made many people realize how serious the deterioration of the climate is, and the high temperature alone is unacceptable. The floods brought about by the worsening climate, not to mention that there may be continuous floods, high temperatures, extreme cold and other abnormal climate phenomena in the future. Perhaps before the day when humans use up fossil energy, the natural climate will wipe out humans. Recent research by scientists has shown that the El Niño Southern Oscillation can trigger changes in the state of the global terrestrial ecosystem if it enters a permanent or semi-permanent phenomenon. In the Earth's climate system, the components of the large-scale structure of the climate system have been identified as important factors related to the Earth's environment. Related research indicates that anthropogenic forcing and disturbance may push it to a tipping point threshold, with impacts on ecosystems and accompanying environments on a global scale. Precipitation simulations for a permanent El Niño state Current climate models state that the Earth's climate is a stable state but in a period of non-equilibrium, with imbalances due to solar radiation and internal feedback mechanisms. Therefore, the properties of the climate system can be relatively maintained at a level close to the average. In a 2008 research investigation, scientists identified several triggering factors in Earth's climate system. These elements are large-scale components of the Earth system that may cross a tipping point that has the potential to change the global climate. Significant changes in the magnitude and frequency of the El Niño Southern Oscillation, including transitioning it into a permanent El Niño state. El Niño state And in the 2015 survey, global climate modelling studies did demonstrate that the possibility of the strengthening of the El Niño Southern Oscillation in the 21st century is due to anthropogenic forcing. This makes greenhouse warming in climate projections more frequent El Niño events, as it lowers the temperature disintegration late in the eastern Pacific, further contributing to the changes in the convective belt observed during the phenomenon. To further assess and identify potential impacts, scientists modeled a control scenario for Earth's climate and used the dataset to compare observations of the current climate to understand the limitations of the model, among other comparisons. Studies related to the southward movement of the Pacific jet and further eastward dispersal show that, under the global large-scale aerodynamic model, the permanent transformation of the El Niño Southern Oscillation into a strong warm phase can trigger the state transition of global land. Areas of asymmetric effect appear between the tropics and temperate zones, with more susceptible areas further shifting into arid biomes. Examples include Central America, the Amazon rainforest, southeastern Africa, and Australia, while parts of North America and Eurasia will become more dynamic as a result. At the same time, related experiments also show that a permanent El Niño phenomenon may trigger a dumping cascade. But in any case, as a global climate event, if it is in operation for a long time, it will undoubtedly bring unpredictable losses and risks to the entire global environment.Changing Ecology
Normally, the ocean trade winds travel westward to the equator and carry warm water from South America toward Asia. Cold water rises from the depths, a process known as upwelling. El Niño and La Niña are both global climate events, and they behave in diametrically opposite ways. The average timing of both events is about every 2 to 7 years, but they don't happen regularly, based on how the climate works. But if nothing else, a long-period El Niño alone is enough, especially for the marine environment. Coral reefs in the normal Pacific model sea serve as an important foundation for marine ecosystems, and not only El Niño, but pulsed heat stress events are also amplifying the impact of global climate change on coral reefs. Scientists have found that the warm phase of the El Niño Southern Oscillation can cause widespread coral bleaching and lead to massive coral die-offs, with a mortality rate of 97 percent. Heat Pulse Stress Causes Starfish Death Normally, coral animals live in symbiosis with endosymbiotic algae. These single-celled algae are found in coral tissue and provide corals with the metabolites they need to survive. The warming of the sea water caused by the El Niño Southern Oscillation will bring pressure to the survival of symbiotic algae. The red and white dots mark the affected reefs as the symbiotic algae have lost their original role, and this symbiotic relationship has been broken, eventually causing the coral to lose its pigmentation. Because the photosynthesis of symbiotic algae can help coral reefs excrete metabolites from the body, but if there is no normal symbiotic relationship before the energy reserves are exhausted, death problems may occur. There are many factors that affect the death of coral bleaching, but the biggest impact is the increase in temperature, including the state of sea surface temperature, which will also put pressure on it. In fact, this is not the first time scientists have observed the impact of El Niño on coral reefs. Since the early 1980s, scientists have observed the impact of extreme events on global coral communities. After bleaching coral reefs in the eastern Pacific Ocean, Indonesia and other places, the mortality rate of coral reefs is as high as 90%. Although corals have some resilience, past surveys suggest that the effects of El Niño and La Niña events may be permanent. From related studies, coral cover decreased significantly after the El Niño event. In the worst cases, coral reef cover was reduced by up to 100%. As an important part of the earth's ecology, coral reefs provide a living environment for many marine plants and a growing environment for many animals. Coral reefs have their own ecological performance Coral reefs account for 25% of marine species in the ocean, and are known as marine tropical rainforests. If there is a lack of healthy coral reefs in the ocean, the consequent blow to the marine ecology will be severe, and the fisheries associated with human beings will also disappear. Climate change is getting worse today, and the human push is clear. Perhaps climate alone cannot destroy human civilization. But the entire natural environment in relation to climate would be severely affected, eventually engulfing humans. The regions with the greatest heat stressclimate tipping points
Warming is bringing more of a boost to the global climate, but the boost will continue Various tipping points arise in gradual changes. The triggering factor or tipping point we mentioned earlier is the climate theory associated with it. Research by climatologist Wally Brock shows that Earth's climate does not appear in a smooth and gradual fashion. Climate change comes quite abruptly. Instead, climate change is abrupt and involves a massive reorganization of the Earth's system. Technically, the climate changes suddenly when the climate system is forced to cross a certain threshold. Scientists now divide the definition of tipping points into two categories, among which are explanations for threshold behavior. What happens after a critical threshold is exceeded? Once the climate system jumps to a different state, then removing this climate forcing, the climate system not only jumps to the original state, but maintains this change for a considerable period of time, possibly even permanently. So in this regard, the semi-permanent El Niño Southern Oscillation model predictions are already revealing this dire change. Global warming can be a hot topic of environmental debate today because it is related to the future of mankind. Research from the Centre for Risk Research at the University of Cambridge in the UK shows that when a planet enters an unstoppable positive-feedback warming loop, it absorbs more heat than it emits until the oceans start to evaporate. At this point the claim can no longer be maintained and this runaway effect occurs. Ancient extinction events are also linked to climate. Scientists have found in past research investigations that every mass extinction event involved some kind of climate change. These events included cooling during the Ordovician, climate change from the Triassic to the Jurassic. species extinction, etc. Human civilization may not be long in history, but it is not that human beings have not experienced it in the past. For example, Homo sapiens during the Ice Age, and the drought in ancient Greece 3,200 years ago. Perhaps the demise of Neanderthals was not an accident, and there are still many thoughts that humans need to face today. Are human beings today the same as in the past? For now, the most critical issue is climate-driven conflict. Future climate deterioration may become a condition that threatens human existence, and we have reason to believe that there will be wars and disputes in the future. From this point of view, climate change may not cause human extinction, but it will definitely affect the survival of billions of life on this blue planet. How the future changes will largely depend on what we do today.- Last：Artificially put in?
