Recently, a news from the US Oceanic and Atmospheric Administration has sparked a strong heated discussion on the Internet, according to this report, the sea temperature in the south coast of the United States has exceeded 32 degrees Celsius.
As a matter of common sense, the normal temperature of the ocean should be between 25 and 27 degrees Celsius, and now reaching 32 degrees Celsius means that the marine environment may have suffered serious damage, which is an extremely dangerous signal.
In this regard, experts from Florida, USA, said: The world is experiencing a serious crisis, and a large area of whitening areas has appeared in the ocean, which is one of the phenomena of high temperature seas.
The earth's ecology is a whole, and the sudden change in the vast ocean, which has always been stable, means that the ecology in other fields will also undergo mutations? Combined with the unusual climate of real life, what is wrong with the world?
The pain of the ocean, the sudden high temperature
According to the sea temperature monitoring chart released by the United States on August 9, the northern Atlantic region has been caught in an endless heat wave, as far as the Caribbean Sea and as close as the North Atlantic Ocean off the coast of Florida, it is red.
Because data monitoring in order to achieve more intuitive visual information transmission, so the high temperature sea area is generally marked in red, the darker the color represents the higher the temperature, if there is pink or even white, it means that the temperature has exceeded the upper limit of the tolerable range.
According to accurate data reports from local observatories in the United States, water temperatures along the coast in Florida have exceeded the 30-degree Celsius mark, especially in the Southwest, where the maximum temperature has reached 33 degrees Celsius.
As we all know, this year has seen a very strong El Niño, which means that the Pacific will continue to experience temperature spikes for the next 10 months or so.
El Niño is a natural climate model, usually the result of a continuous large change in ambient temperature, usually once in 2 to 7 years, but there are also strong and weak, although under normal circumstances will raise the ocean temperature, but it will not be as exaggerated as this time.
On July 6 this year, a data monitoring result in the United States showed that the average surface temperature soared to 17.23 degrees Celsius that day, directly setting a new record in the history of world temperature.
A professor of meteorology at the University of Leipzig in Germany said: "The persistence of hot weather is symbolic, and the last such exaggeration was the interglacial period, but that is now 120,000 years old. ”
The World Meteorological Organization speculates that the average temperature of the equatorial region of the Pacific Ocean is already 2 degrees Celsius higher than in normal years, which will not only cause wind direction disturbance on the sea surface, but also bring tropical warm winds to the southern region of the United States, further exacerbating the sea temperature in the Gulf of Mexico and other places.
The most perverse thing is that in June and July this summer, the southern part of the United States was not affected by cold air masses, and at the same time suffered from strong direct sunlight, and high temperature weather was unusually frequent, which would not be the norm under normal circumstances.
At the same time as the high temperatures of the oceans, other unconventional natural climates began to surface. On August 9, a fire broke out on the Hawaiian island of Maui, USA, killing 36 people and many missing people unaccounted for.
The polluting gases from the fires spread all around, causing 14,000 households to lose power and making it difficult to purify the smoke after the fire, so many local residents chose to jump into the sea to take shelter.
At the same time, there are strong thunderstorms in the eastern United States, accompanied by lightning and powerful hurricanes raging on the sea, you must know that marine heat waves often produce hurricanes, and these natural disasters are inextricably linked to the sudden warming of the sea.
Global climate issues, red flags
Global warming is no longer new, this phenomenon has been increasing day by day for more than a decade, greenhouse gas emissions day after day, the ocean, as the largest thermal energy storage space on the earth's surface, absorb all these negative hazards.
But today, it's clear that the oceans are beyond their limits, and over-absorption of heat leads to rising sea temperatures, creating a vicious cycle.
Limited to the North Atlantic region, the increase in the average temperature of the sea is a catastrophic event, no one can know exactly how large the ocean is, and it is impossible to accurately consider how the ecosystem it contains can affect the world, but once the original stable balance is broken, the consequences will inevitably occur.
The recent streak of typhoons around the world is a perfect illustration of the impact of catastrophic ocean hurricanes, which require enough heat to sustain formation, and once the ocean temperature exceeds 32 degrees Celsius, megahurricanes tend to occur.
At this time, it is already irrational for people to think about how to respond, and the rainfall and storms brought by hurricanes are difficult to resist, not to mention the powerful hurricanes that directly make landfall.
According to NOAA's forecast, there will be at least 15 named hurricanes around the United States, and even 5 super hurricanes, which will affect not only the United States, but also many South American countries.
If hurricanes move along the Pacific Ocean and are again affected by warming at sea levels, there may even be unacceptable hurricanes around the world.
In addition to the hazards on the surface, there are also changes below the surface. It is well known that coral reefs are one of the richest ecosystems in the world, and their presence plays a huge role in maintaining the stability of the marine environment.
Recently, the ocean temperature has soared, and corals have also experienced many bleaching symptoms, they are dying one after another, and those miniature creatures that were originally protected by corals have also been affected to varying degrees.
At the same time, corals play an important role in medicine, tourism and coastal protection, not only for drug production, but also to protect the safety of coastlines.
However, according to the NOAA data report, there is widespread bleaching of coral reefs in parts of the North Atlantic in the United States, and up to 90% of the most serious areas, which will cause serious losses to the stability of marine life.
Viruses or marine parasites that are otherwise unsuitable may also come to their paradise, after all, heat waves carry many things that can pose a threat to humans.
At present, there have been many times in the North Atlantic Ocean surface heat flow accumulation phenomenon, according to the data given by NOAA, the world is indeed warming.
Experts warn of the eventual catastrophic consequences
According to decades of meteorological research, rising ocean temperatures mean to some extent a spike in the world's environment, but every increase in the world's average temperature brings severe drought.
In 1965, precipitation in northern China began to decrease year by year, and the precipitation in northern China decreased by one-third compared with the past decade, which means that the available water resources are decreasing, thus forming a vicious circle.
This year's floods in North China are related to the previous years of drought, and excessive temperatures will make the environment lose its stability, and it is prone to the danger of frequent natural disasters.
It is widely recognized in the world that the equator is hottest and the north and south poles are the coldest, but as the temperature continues to rise, glaciers are melting rapidly every year.
The global surface has been short of water for the past hundred years, and today there is an anomaly that the Arctic is not cold enough and the equator is too hot.
According to the conclusions of the World Meteorological Organization, the cold air in the North and South Poles can easily leave the Arctic region, and the warm currents and hot air from the outside continue to invade, so that the temperature will only become more and more extraordinary.
It is not difficult to see in our daily life at this stage that today's summers are hotter earlier and last longer, and winters are falling less and less under snow, but the weather is getting colder and longer.
But when the seasons are no longer clear, extreme weather will only increase. Academician Ding Yihui of the mainland said: "Before the temperature difference completely disappears, there will definitely be a big warming in the Arctic."
At that time, rising sea levels will definitely cause many cities to suffer, such as those coastal areas, China's Shanghai, Hong Kong, etc., will be seriously affected, and even island countries like Japan may become the first wave of waves to fall.
Therefore, we should be more aware of the urgency of global warming, the high temperature of the sea south of the United States has once again sounded the alarm, and mankind is facing severe challenges.
Slowing global warming can only become a reality when the world cooperates more.
epilogue
The earth is the earth of all, and the protection of the environment of the homeland is important, and when we lose the basic environment on which we depend, we may regret it.
The sudden rise in temperature has sounded the alarm for mankind, and although it is difficult for us to intuitively feel the harm caused by abnormal temperatures in our daily lives, it is still a problem that everyone needs to consider.
In any case, I hope that the natural environment can return to normal, after all, it is related to everyone's normal survival, if you can't even get out, why talk about daily life?
