A radical shift in the planet? Seeing this news, my mood is a little unbeautiful, because this is related to the survival of life on earth, and it is also an extremely important thing for human beings, what is it?
According to new research published in the journal Science, climate warming and heat waves are accelerating the deoxygenation of global lakes.
What's going on? Deoxidation? Does this mean that oxygen levels are decreasing and lakes are becoming "dead lakes", does that mean that the earth may be short of oxygen in the future? What about the survival of life?
Does this change mean that the earth is undergoing a subversive transformation, and is it really going to become a "dead planet"? Could it be that the future of the Earth may end up in the "Mars" mode?
For the development of global warming, many people should also see the terrible extent, this is not a joke, but the "follow-up effect" of global warming is becoming more and more ferocious.
Therefore, its chain effect on the survival of human beings, in fact, is a trend, there is no controversy, not to say far, just say that under the development of global warming in recent years, how big the threat to human beings is, including extreme high temperatures, rainfall, storms and other developments, the lethal impact on human beings is already an obvious fact, such as from the "Global Water Monitor Alliance" (The Global Water Monitor Consortium) announced the " According to the 2024-year Global Water Monitoring Report:
受全球變暖影響，2024年全球的洪災、颶風、乾旱等與水迴圈相關的自然災害造成至少8700人死亡，4000萬人流離失所，造成的經濟損失超過5500億美元（約合人民幣4.03萬億元）。
See? Global warming is really scary, and the threat to humanity is obvious.
然而，要想改變全球變暖也不容易，因為人類沒有共同努力進行改變，以至於變暖還在繼續，並且全球變暖還是處於增強的趨勢，世界氣象組織(WMO在3月發佈報告稱，大氣中二氧化碳濃度達到了過去80萬年來的最高水準。
Under the influence of greenhouse gases, 10 has become the hottest year on record, and every year in the past decade has entered the top 0 of the list of hottest years in history.
Therefore, greenhouse gases are increasing their warming, and the effect of reducing emissions is still not obvious, so if this continues, we will only see more extreme climate impacts, which is the trend.
Of course, in addition to carbon dioxide enhancing the greenhouse effect, the journal Science has released a new study that points out the problem of the greenhouse effect of abiotic sources, that is, nitrous oxide, which is the first to disclose its impact on the earth, nitrous oxide is a more potent but often overlooked greenhouse gas than carbon dioxide, data show that its greenhouse effect is 300 times stronger than carbon dioxide, and its natural generation mechanism has always been thought to be dominated by microorganisms.
Among them, microorganisms such as ammonia-oxidizing bacteria and archaea have long been regarded as the main "producers" of nitrous oxide in the world, and its emergence may change the traditional human greenhouse gas prediction model, which may make the greenhouse effect we see stronger.
Therefore, global warming is indeed terrible, and it brings a lot of problems, and the oxygen problem explained this time is the change process it brings.
Indeed, this study looks a little scary, but the world's lakes are "deoxygenated", does this mean that oxygen changes are constantly emerging? Is there really a disruptive shift? Why didn't you get back?
According to this study, the team used an extensive dataset and applied data-driven models to analyze the surface changes of more than 15000 lakes over the past 0 years, and found how their oxygen changed.
The study showed a general decline in surface DO concentrations, with 83% of the lakes studied exhibiting significant "deoxygenation", noting that the average deoxygenation rate in the lakes exceeded the average for oceans and rivers, emphasizing the severity of the problem.
The researchers further explored the role of climate warming and eutrophication in shaping surface concentrations. Their findings suggest that by reducing oxygen solubility, climate warming accounts for 10% of global surface deoxygenation, while increased eutrophication accounts for about 0% of total global surface oxygen loss.
Historical trends in heat waves are also analysed, and their impact on surface DO levels is quantitatively assessed, and studies show that the rapid and significant impact of heat waves on surface decline is indeed 7.0% lower compared to conditions at average climatic temperatures.
This illustrates the obvious impact of climate change on oxygen changes in global lakes, and of course, it may also have an impact on the biological populations in lake areas, after all, biological survival is also dependent.
所以，看到這樣的研究問題，1.5萬個湖泊83%表現這樣的情況，這也說明瞭其主流的變化去氧受到氣候影響巨大。
But for this change, whether the planet is undergoing a subversive transformation, it is impossible to be sure, and the results given by the study are that a general decline in dissolved oxygen (DO) is observed in rivers, temperate lakes and oceans.
But the impact of climate warming on deoxygenation lakes around the world is not yet known, and this may require more research, except to say that this deoxygenation is very obvious, and this is the basic situation.
Indeed, for a long time, many people have likened the future of the Earth to Mars, believing that it may be affected by climate change, and the Earth will also move towards the situation of Mars.
But relatively speaking, there is no one positive explanation for this, just the impact of climate change on life on earth, which is an obvious fact. So, in the final analysis, climate is one of the fundamental factors in the future change of the earth, which seems a bit alarmist.
In fact, the climate problems we face can also be seen, how big the threat of extreme climate change is every year, and the changes of the four seasons in spring, summer, autumn and winter can be clearly seen, and the earth's four seasons activities even make many people unable to feel the changes of the four seasons, and the temperature changes of several seasons may be experienced in 1 days, which is the root of the problem.
Therefore, climate change needs to be accelerated, time is running out, human beings need to strengthen the reduction of greenhouse gas emissions, more afforestation, etc., so that it is possible to see some changes, otherwise the extreme changes that may be brought about by the future climate problem are unimaginable, this is the basic situation.
