Throughout this summer, heat waves have swept across the northern hemisphere. The National Meteorological Center has issued heat alerts for 24 days in a row, with red alerts, the highest level, issued twice in the past two days.
Much of the high temperature records have been refreshed, couldn't even on the temperature of the national ranking 40 degrees, nearly 10 years, global warming trends, polar sea ice to melting, the frequencies of extreme high temperature are also more and more high, in addition to human emissions of greenhouse gases, the sun's recent activity also cannot be ignored.
The sun is closely related to the earth. The earth receives all the light and heat from the sun, so if the sun changes, the earth will be affected.
The observed data show that the sun has been much more active since August, with 36 coronal mass ejections occurring in just two weeks, which is almost a blowout 39bet-kết quả bóng đá-kết quả xổ số miền bắc-kèo bóng đá -soi cầu bóng đá-đặt cược. What is the relationship between the recent extreme heat in China and the sun's activity? Will this situation continue to intensify in the future?
Our sun is a yellow dwarf star with a spectrum of G2V and a lifetime of about 10 billion years. It was born in a primitive nebula about 4.5 billion years ago, so a conservative estimate of its life span is over 5 billion years.
When hydrogen consumption after the completion of the solar interior, the sun will swell into a red giant, earth will be affected by the big, red giant phase, the sun at helium fuel for nuclear fusion, but the helium fusion is not stable, the surface of the gas will expand, the earth may be consumed by the sun's surface, in the internal operation of the sun, the earth also will become a real ball of fire, Completely inhospitable to life.
So how did the Sun's recent coronal mass ejections affect Earth?
The corona, the outermost part of the sun's atmosphere, is a million degrees Celsius and is made up of high-speed electrons and plasma. When the magnetic field of the corona is disturbed, for example by a solar flare, a coronal mass ejection is the largest and most violent release of energy in the solar system, with the ability to destroy the earth and the sky.
During the eruption, clouds of extremely hot particles and plasma will blast around at tens or even thousands of kilometers per second, some of which will be deflected by the Earth's magnetic field, while others will hit the Earth directly.
According to NASA, similar eruptions from the sun will continue to increase over the next few years, peaking in 2025 and continuing to affect Earth.
These high-speed plasma magnetism, and damage the earth's ozone layer, satellite and radio communication will be affected by the larger. The outbreak of such phenomenon belongs to the normal cycle of change, it is currently in a solar cycle 25, 2022, is a straight line development phase, so the activity will continue to upgrade.
Some solar storms do have an impact on Earth's climate, so it has been suggested that this year's extreme heat across many parts of the globe may be linked to a recent coronal mass ejection. However, scientists have not yet determined the effect of solar activity on short-term climate, and cannot conclude that this event is completely related to the sun.
What is certain is that there is a direct link between the recent high temperature and high pressure anomalies.
Under the control of high pressure system, downdraft prevails in most areas. When air masses sink from high altitude to low altitude, the ground will be heated and pressurized, and the air will become dry and unable to form clouds and fog.
Thus on the one hand, because of the reduced cloud cover, and the sun through the heat of the ground will be increased to make the surface to heat up, on the other hand, the bottom of the air near the ground by the sun's radiation would have rising inflation after warming, but high pressure sinking airflow would like to cover the hot air in low pressure, prevent cold air into the, cycling can lead to temperature rising, caused the extreme heat.
Whether it's because of the subtropical high or because of the sun, Earth's climate is getting more extreme.
The Sixth Assessment Report of the United Nations Intergovernmental Panel on Climate Change points out that global warming in the last 50 years is occurring at a rate unprecedented in the past 2000 years, which is a red alert for all mankind.
In addition, it is clearly pointed out that greenhouse gases emitted by human activities are the main reason for the increase in the intensity and frequency of extreme high temperatures. When global warming reaches a certain extent, the extreme high temperature we are experiencing now may become normal.
So change is imminent, destiny is in their own hands, and if the status quo continues, it is obvious what will happen in the future.
