Scientist: The volcanic eruption in Tonga is a wake-up call, and humanity should be prepared

author:The little red of popular science every day

Preamble:

In 2022, extreme heat events around the world, some places hit record highs, sparking renewed attention to the issue of global warming. Under the influence of this wave of heat waves, severe droughts and river outages have occurred in many places, which have had a great impact on the local ecological environment and agricultural production.

At the same time, a recent issue of the journal Nature published research suggesting that the Earth may return to a "summerless year", raising concerns about the future of climate change. At a time when there is speculation about whether there will be a volcanic eruption to "save" the earth, scientists have also explained this, saying that although volcanic eruptions can indeed bring some cooling effects, they cannot reverse global warming, and may have a greater negative impact on the earth.

So, in the face of a possible "summerless year" in the future and the risk of large-scale volcanic eruptions, how should humanity respond to the challenge of climate change?

1. The earth may reappear in the "year without summer", and volcanoes cannot reverse global warming

1. This year, extreme heat has occurred in many parts of the world, and many places have reached record highs

This past summer, many parts of the world experienced extreme heat, including some areas with milder temperatures all year round, and in some places even set record highs since meteorological records began.

For example, in Australia, the local meteorological department has issued an alert, saying that the temperature in the southern part of Australia will reach 50 degrees Celsius, which is like being in a furnace, and such high temperature weather has also brought a great impact on the local ecological environment and agricultural production.

In some European countries, this year's summer has also been unusually hot, and in some places there has even been persistent high temperatures, which has exacerbated the already dry climate, and local farmland and forests have also been hit by fires.

2. The Earth may return to the "Year Without Summer", and volcanoes cannot reverse global warming

And just when there is a lot of talk about this year's hot weather, a recent issue of the journal Nature published a study that pointed out that the earth may return to the "year without summer" in the near future, when the temperature will continue to rise on a global scale and there will be no summer everywhere.

Such a prediction undoubtedly has a great impact on people's lives, after all, summer is an extremely important season, many crops are grown and matured in this season, if it really reproduces the "year without summer", it will undoubtedly be a devastating blow to local agricultural production.

In the face of such climate change, many people may have high hopes for scientists, thinking that they must have a way to solve this problem, and perhaps the most common thing that comes to mind is to use volcanic eruptions to "save" the earth, because volcanic eruptions can release large amounts of volcanic ash and sulfur dioxide into the atmosphere, thus forming a "parasol" to reduce the exposure of sunlight and bring a certain cooling effect.

However, scientists say that the current climate problem of the earth is not because the sunlight is too strong, but is inextricably related to the emission of greenhouse gases, so even if the volcanic eruption reduces the exposure of sunlight, it cannot change the amount of greenhouse gases in the atmosphere, let alone fundamentally solve the problem of global warming.

On the one hand, a large amount of volcanic ash and sulfur dioxide will cause damage to the local ecological environment, on the other hand, it will also have a certain impact on human life and health, and may even cause more natural disasters, so volcanic eruptions are not a "panacea" for climate problems.

Second, the recurrence rate of large-scale volcanic eruptions is high, and human beings need to have countermeasures

1. Volcanic eruptions can cool down, but they can cause more casualties

Although volcanic eruptions cannot reverse global warming, they can indeed bring a certain cooling effect to the earth, which should not make people feel a little "lucky" about it, thinking that volcanic eruptions may be able to alleviate the impact of hot weather on the earth.

However, in fact, the recurrence rate of large-scale volcanic eruptions is not low, and once such a natural disaster occurs, it will have a very big impact on the earth's ecological environment and human life, and may even lead to more casualties.

Take the previous Naples volcano, for example, a volcano that had been dormant for centuries and had a devastating impact on the local population when it erupted, and such volcanic eruptions are not unique, there are many similar volcanoes around the world that are "sleeping", and if they erupt repeatedly, they will have a catastrophic impact on the surrounding area.

2. Humanity needs to have a response and a contingency plan

In the face of the hidden danger of large-scale volcanic eruptions, human beings cannot control the forces of nature, but there are ways to mitigate the impact, and this requires the joint efforts of all countries in the world to jointly formulate measures and emergency plans to deal with volcanic eruptions.

First of all, scientists should strengthen the monitoring of volcanic activity, and once signs of a possible eruption are found, they can notify local residents to evacuate as soon as possible to reduce the occurrence of casualties.

Second, the volcano can also be artificially "detonated", and if conditions permit, scientists can appropriately inject some water or other substances into the volcanic vent, so as to release the volcano's energy in advance and reduce the power of the eruption.

In addition, governments need to have a well-developed disaster response plan in place so that in the event of a large-scale volcanic eruption, they can act quickly to protect the lives and property of local residents.

Third, greater efforts must be made to change the climate and reduce disasters and human casualties

1. Warming is already causing casualties and is sustaining or triggering more disasters

At present, global warming has brought extreme climate phenomena to the earth, such as this year's high temperature weather, as well as the extreme rainfall and floods that occurred not long ago, which are the results of warming, and have caused immeasurable losses to human life and property security.

If this climate phenomenon continues, the resulting disasters and impacts will become more severe, and there is a risk of more casualties, so it is imperative to take action to change the current situation of global warming as soon as possible.

2. Humanity needs to act, not rely on volcanic eruptions

In the current climate problem, human beings can no longer have a fluke mentality about nature, thinking that the earth will definitely "get better" because of volcanic eruptions, but should clearly understand the root cause of warming, reduce greenhouse gas emissions, and protect the earth's ecological environment.

Only in this way can we fundamentally solve the climate problem, instead of waiting for natural disasters such as volcanic eruptions to "help" the earth, because once a volcanic eruption does bring a cooling effect, it will also bring more harm to the earth and more disasters to human society.

Epilogue:

The emergence of a summerless year has made mankind full of worries about the future, and the risk of large-scale volcanic eruptions has brought a certain uncertainty to the earth, and the climate challenges facing humanity are also unprecedented, but we should not be intimidated by these problems, but should bravely face them and take action to work together to change the future of the planet.

May everyone be aware of the urgency of climate issues, protect the earth we live in, start from themselves, reduce energy waste, choose more environmentally friendly travel methods, and participate in climate change actions together, so that our future is no longer full of worries, but full of hope and beauty.
