Earth's environmental changes have caused many scientists headaches, because,
with the rapid development of human beings, the Earth's global warming problem is becoming more and more serious, due to the continuous rise in the Earth's temperature, resulting in the melting of the Earth's glaciers, the sea level is also rising rapidly, this series of changes are making the survival of mankind is facing a crisis, many areas are also facing the crisis of being swallowed by the ocean.
The Earth's ecosystem has been destroyed and the environment is in danger, making humans feel the unprecedented crisis, but one wave has not yet subsided, the Earth's environmental problems have not yet been solved, and the Sun has anomalies, some scientists said that the Sun will welcome the rare "Little Ice Age", sunspots will continue to disappear for several years or even decades.
As the center of the solar system, the sun is very important to the role of the solar system, and the Earth is also dependent on the energy provided by the sun, if the solar activity is no longer active, then the Earth's life will also be affected. It is known that the sun's magnetic poles change every 22 years, and sunspot activity takes place in an 11-year cycle.
The sun's cycle of activity started in 2009, so the next cycle of solar activity will start in 2030 according to the sunspot activity cycle. In 2015, scientists warned that the sun will enter a "dormant period" in 2030, which will cause the Earth's temperature to drop significantly and make the Earth enter a "mini ice age".
In addition, scientific studies have shown that the sun is becoming "quieter" and solar activity will decrease by 60%, which will lead to a sudden drop in the earth's temperature and the earth's environment will enter an extreme again. Due to the cold climate, crops will not be able to grow and people will face famine and other problems.
The Little Ice Age is no stranger to the Earth. Starting around the beginning of the 15th century, the global climate entered a cold period, commonly known as the Little Ice Age, which ended in the early 20th century. At that time, the Little Ice Age in Europe led to the shrinking of farming areas, and as the northern winters became colder, fish stocks changed their migration paths, making life difficult for fishermen and farmers.
It is known that at that time in Europe because of the cold climate led to more than 400 deaths, some shipping lanes were also frozen, the life of the inhabitants had a big problem, so once the Earth entered the Little Ice Age, it will be a big blow to human beings, which also means that the Earth's climate again becomes bad, human survival is really a problem.
Now the global warming problem facing mankind has not been solved, Stephen Hawking has also predicted that the Earth's temperature will get hotter and hotter, and ultimately unsuitable for human survival, perhaps in the future the Earth is really no longer the only home for humans, humans want to survive in the long run, may really have to move to outer space.
