Are Hawking's predictions scientific?

Hawking has made many predictions, one of which is very important to each of us, and that is global warming.

Since humans entered the industrialization era, the problem of global warming has been intensifying, and in recent years, changes in the earth's climate have been clearly felt. For example, the average temperature has increased by 1.2 degrees Celsius compared with previous years, and may even exceed the "critical point" of 2 degrees Celsius in the future!

Even as ordinary people, we can feel that winters are getting shorter and warmer, and summers are getting hotter and hotter. This year, North America even experienced high temperatures of nearly 50 degrees Celsius, and they did not last long. short. Are Hawking's predictions scientific?

From the perspective of global warming, Hawking’s prediction is very reasonable, because the phenomenon of climate warming is indeed intensifying now. However, Hawking's prediction also has some one-sidedness, that is, he believes that as the earth's warming continues to intensify, the earth will become "another Venus" and the surface temperature will reach several hundred degrees Celsius. By then, humans will no longer be able to continue on the earth. Survive.

However, the possibility of the surface temperature reaching several hundred degrees Celsius is not high. Although the earth has been heating up and greenhouse gases in the atmosphere are also increasing, scientists currently do not agree with this statement, that is Said they don't think the surface temperature will become as high as Hawking predicted.

It is a fact that the earth's temperature continues to rise, but this change brings not only extreme high temperature weather, but also extreme cold weather, so a surface temperature of several hundred degrees Celsius is too "exaggerated" . Will disasters be frequent in 2021?

In recent years, extreme weather has occurred every year, such as the rare high temperature weather in the Arctic in 2020 and the wildfires in Australia, which have affected the living environment of three billion animals. In 2021, there will be more such situations, such as extreme rainfall, tornadoes, floods, high temperature weather in North America, etc., which have indeed affected the living environment of many people.

From this point of view, climate problems are indeed getting worse year by year, and extreme weather events are becoming more frequent year by year. Perhaps the earth’s climate is approaching a “critical point”. If we still want to If we live on earth, we need to increase environmental and climate protection efforts, reduce greenhouse gas emissions as much as possible, and perhaps "slow down" the pace of climate change.

Judging from the trend of global warming, the possibility of extreme weather may become higher. Whether 2021 will be a "disaster-prone" year depends on the year-end summary. Analysis report. However, judging from the phenomena that have already occurred, this year is indeed not easy, and the weather is really weird.

Whether Hawking’s prediction is accurate or not, global warming has indeed become a serious trend. But as he said, in the future, the temperature of the earth’s surface will reach hundreds of degrees Celsius. This possibility is Not very high anymore. Therefore, Hawking's prediction about the temperature of the earth has a certain basis for reality, but it is not completely correct.

For us, it is important to work hard to improve the current climate state and not make it worse, whether it is 2021 or any future year, if we do not change the climate, Extreme weather will become more frequent and severe.

If we can reverse the phenomenon of global warming, we can reduce the frequency of extreme weather from the root. Therefore, start working hard to protect the environment and reduce carbon emissions from now on!
