Which is more terrifying, global warming or global cooling?

Equally scary, but global warming is even scarier!

If global warming will become like Venus, it will rain sulfuric acid, absorb carbon dioxide, see desertified land, and experience a high temperature of 500 degrees Celsius...

And global cooling is just like Europa, or like the popular movie "The Wandering Earth" at the beginning of the year. People in the ice and snow can still make engines to deorbit the earth and go into space. Traveling in the middle. The highest and lowest temperatures of the universe

The most important thing is that in the temperature of the universe, the temperature can increase infinitely, but it cannot decrease infinitely.

The lowest temperature in the universe is absolute zero -273.16. At this temperature, atoms will also stop moving. However, the Boomerang Nebula, the lowest in the universe, also has -272; most of the vacuum in the universe has -270.15 (cosmic microwave background radiation); interstellar dust has -260; Pluto, the coldest in the solar system, has -240; Titan has -200; Europa has a temperature of -163; the temperature of Mars is -63; the minimum temperature of the moon is -120; the minimum temperature of the earth is -90, and the average temperature of the earth is 15; the minimum temperature of Venus is as high as 400; the sunspot temperature is 4000, and the prominence is 5000.

The livable temperature for humans is -10°C, the human body temperature limit is 40°C, and the current average temperature of the earth is 15°C, which is a suitable climate. Global Warming

However, since the Industrial Revolution in the 1760s, humans have burned a large amount of coal, oil, fossils and other fuels, and the release of carbon dioxide and other greenhouse gases into space has increased dramatically. rising, creating an increasingly intensified greenhouse effect. From 1860 to 1900, the average temperature of land and ocean increased by 0.75; from 1981 to 1990, the average temperature of the earth increased by 0.48 compared with 100 years ago; in the 20th century, the average temperature increased by 0.6. Global warming is causing glaciers to melt and sea levels to rise, seriously threatening the ecological balance and endangering humankind's own survival.

Scientists from the American Center for Atmospheric Research said that even if human greenhouse gas emissions are maintained at 2000 levels, global warming and sea level rise are irreversible. Unless humans return to the primitive farming and burning society, all carbon emissions will stop.

But which country is willing to stop? If humans continue to destroy the earth in this way, it will not take 1,000 years for the earth to become an extremely hot but dead planet like Venus. Scientists predict that the earth will become a planet shrouded in the greenhouse effect like Venus in about 3 billion years.

And if the earth cools down, it will be like Mars or Europa. Although it is cold, as long as there is water and air, you can still live in a space suit. Global warming or global cooling are both terrible. They will cause global ecological disasters and cause huge survival and life crises for mankind. But which one is more terrifying? There is currently no clear scientific answer!

Global warming and global cooling are nature’s most obvious and strongest warnings to humans: the earth’s ecological balance is out of balance, and nature is about to fight back and punish humans! 1. Global Warming - Greenhouse Effect

Since the Industrial Revolution in the 1760s, humans have released large amounts of carbon dioxide into space due to the burning of coal, oil, fossils and other fuels. Greenhouse gases such as carbon dioxide are rising sharply, creating an increasingly intensified greenhouse effect. Due to the continuous accumulation of the greenhouse effect, the energy absorbed and emitted by the earth-atmosphere system is unbalanced, and energy continues to accumulate in the earth-atmosphere system, resulting in temperature rise and global warming.

Global warming will redistribute global precipitation, melt glaciers and permafrost, and raise sea levels. It will not only endanger the balance of natural ecosystems, but also threaten human survival.

On the other hand, due to the emission of land-based greenhouse gases, the temperature on the mainland has increased, and the temperature difference with the ocean has become smaller, which has slowed down the air flow and prevented the haze from being blown away in a short time, causing haze in many cities. Increasing weather conditions affect human health. Measures such as vehicle restrictions and production suspensions have only short-term and partial effects, and cannot fundamentally change climate warming and haze pollution. 2. Global cooling - the sun’s luminous intensity decreases

Global cooling became the academic mainstream in the early 1970s.

Scientists claim: Because the sun continued to maintain unusually high luminosity almost throughout the 20th century, the earth passed the peak of global warming from 1998 to 2005. After that, the luminous intensity of the sun gradually decreases and will reach its lowest point around 2041. This is the reason for the significant cooling of the earth. However, the ocean will delay the process of significant cooling of the earth, and the peak period of global cooling will occur. In 2055 to 2060.

When global cooling occurs, sea levels will first drop and the continental shelves will be exposed. Then there would be massive migrations of plants and animals across the globe, and we humans would continue to migrate along the continental shelves to warmer places around the world.

Global agricultural output will generally decline significantly, but it does not rule out the emergence of new oases in high-temperature and dry areas that will be revitalized. The Sudan region may become humid, but this will not affect the overall food output. Food production will decrease, there will be more violence in Africa and the Middle East, and famine will occur in all countries. Conclusion:

The earth is the only home for human beings to survive. When humans treat nature well, they treat themselves well. Protecting the environment means protecting ourselves. Protecting the environment is a matter for everyone.

Global warming is even scarier. Global warming will lead to water shortage over time. Without water, there will be no life; cooling will be equally terrible. However, in a short period of time, intelligent human beings will gradually use scientific and technological means (light, electricity, heat energy) to maintain The continuation of life. In short, both warming and cooling are ominous signs. Human beings must take care of their home planet and protect the ecological environment.
