Which of Hawking's predictions do you think is the most incredible?

Hawking has four major predictions, and the most incredible prediction is about the "Earth". Hawking predicted: If global warming continues to intensify, humans will not be able to survive on the Earth. Judging from today's trends, it is true that the earth is now developing in the direction predicted by Hawking.

Of course, in addition to this prediction, there are three others that are recognized, namely: there was nothing before the Big Bang, the universe has no boundaries, and the thorough development of artificial intelligence may lead to the demise of mankind.

Although the development trend of artificial intelligence is affecting human life, there is no such trend in predicting that artificial intelligence may lead to the demise of mankind. The most incredible thing is the problem of the earth. Warming is indeed happening, and it is becoming It's getting more and more severe.

Will 2020 be a disastrous year?

According to data released by NASA, the earth once again set a new high in average temperature in 2020, with the overall temperature already about 1.25 degrees Celsius higher than in the pre-industrial era. Some studies point out that land areas The average temperature is even 1.96 degrees Celsius higher, so the earth is really getting hotter. 2020 is basically the same as the record set in 2016. However, the temperature rise in 2020 still occurs under the La Ni?a phenomenon that affects the climate.

Everyone knows that the La Ni?a phenomenon will cause the earth to cool down and alleviate global warming. In 2016, there was still a strong El Ni?o phenomenon, which increased the temperature of the earth. What will happen? Cooling has leveled off to rising temperatures, so the earth is still warming, and catastrophic problems are becoming more and more serious. Therefore, many people say that 2020 may be a catastrophic year. This conclusion is not a big problem. Except that warming is catastrophic.

There is another typical example in 2020, and that is the Australian fires. Australia's record high temperatures and drought triggered catastrophic forest fires in early 2020. The fires burned nearly a quarter of the forest in southeastern Australia, destroyed more than 3,000 homes, and killed an estimated 143 million mammals, 2.46 billion reptiles, 180 million birds, and 51 million frogs. Death or displacement, so this is a common disaster between animals and nature. It is really too serious.

Of course, if humans do not change the climate, the earth will become even more extreme in the future. But what we see now is only the "tip of the iceberg", and many phenomena on the earth are still unknown to humans.

Is Hawking’s most incredible prediction accurate?

As we said before, the extreme changes of the earth are what Hawking predicted, but it is impossible to judge whether they are accurate or not. Although the extreme climate phenomena we are facing today are relatively severe, what Hawking predicted is true. It's more serious, it can be said that it's beyond everyone's knowledge. Hawking pointed out in his prediction that if the earth continues to warm in the future and global warming continues to intensify, then the future area may become today's Venus, and the surface temperature of the earth will be as high as 460 C by then.

At this time, the life of the earth is in a "special pan-yaki" state. Human beings will definitely not be able to survive in the deep-fried mode. Therefore, Hawking predicted that it can still resist the high temperatures we are facing today. , it will not be possible in the future. At the same time, his basis is that Venus was the same as our earth in the past, and it was a celestial body suitable for life. However, with the continuous increase of carbon dioxide gas, the temperature of Venus gradually increased, and eventually turned into a fireball, that is, Today's appearance.

Therefore, Hawking believes that if the carbon dioxide concentration in the earth's atmosphere reaches an extreme value, which is what we call the earth's "critical value", then the earth will also face the same consequences, which is very worrying. Although I personally believe that it is impossible for the earth to experience temperatures as high as 460 C, the continued warming of the earth is an obvious fact that is undeniable. So it doesn’t matter whether Hawking’s prediction is accurate or not. The most important thing is that the climate has really become more extreme.

Will 2021 be a year of disaster?

Judging from the phenomena that have occurred on the earth today, it is true that the extreme nature of the earth has increased, and the catastrophic problems caused by it have also become stronger. For example, nearly 85% of Mexico's regions are experiencing drought, with none of the 210 major reservoirs holding 100% water, 30 reservoirs holding more than 75% water, and 19 reservoirs holding less than 50% water. So it's really an extreme drought attack. As for our country, we are actually facing an extreme climate.

The most typical one is the "sandstorm". Sustained drought has occurred in southern China, southwest and other places. Although it has been alleviated in many areas, it has still not been completely relieved in all areas, so extreme climate phenomena It has sounded a "wake-up call" to us, which means that 2021 may not be better than 2020, and there may be more catastrophic problems, so 2021 may also be a catastrophic 100 million years.
