NASA scientists warn that the absence of sunspots could lead to record cold temperatures on Earth in just a few months
A new alarming trend in the atmosphere could mean a significant decrease in the temperature of the thermosphere, and could happen sooner than anyone could have predicted previously.
Using NASA's TIMED satellite, which measures changes in the Earth's atmosphere, scientists have determined that the atmosphere is losing thermal energy. in a Space weather characteristic, Dr. Mlynczak explained to Dr. Tony Philips how this development is well above the surface of the Earth at the edge of space It could bring record cold temperatures.
Sunspots no more?
The usual sunspots seem to have disappeared for most of this year, which led to these massive losses of thermal energy and caused the thermosphere to cool and contract.
The SABER instrument installed in the TIMED satellite controls the infrared emissions of carbon dioxide and nitric oxide. Both substances are crucial to maintain the overall balance of energy. Part of the SABER instrument is the Thermosphere Climate Index (TCI), created by a group of researchers led by Dr. Mlynczak, which shows the amount of molecules that trap heat such as carbon dioxide and nitric oxide free in space. The current measurement of 33 billion watts of infrared power of nitric oxide is ten times less than what is considered normal during the most active phases of the solar cycle. According to Dr. Mlynczak, this terribly low number could lead to record cold temperatures in "a matter of months".
Solar activity cycles generally last about eleven years, and the prolonged inactivity of last year, as evidenced by the lack of sunspots, could cause temperatures to plummet into the thermosphere, which is a gas layer located 60 180 miles (100 to 300 miles). kilometers) on the surface of the planet.
Scientists do not yet understand the full implications of sunspots, but they occur in areas of strong magnetic activity as part of the eleven-year solar cycle.
The particles in Earth's atmosphere are agitated by ultraviolet radiation emitted by sunspots, which causes these particles to heat up. With the absence of sunspots for most of this year, which results in a lack of agitation, this is what is causing the upper atmosphere to lose thermal energy. The research seems to indicate that, while significant changes may occur on Earth, it is unlikely to have much effect on the climate that is experienced on the surface of the planet. The absence of sunspots will not lead to climate change.
During the solar minimum phase of the eleven-year activity cycle, the ultraviolet output of the sun drops substantially and the Earth's upper atmosphere reacts accordingly, says Dr. Martin Mlynczak.
The Solar Minimum phase also leads to an increase in the amount of space debris that can be allowed to accumulate in Earth's lower orbit.
Another effect is the increase in solar winds, which can be the cause of more lightning and abnormal cloud formation due to the alteration of the chemistry of the Earth's upper atmosphere.

Air transport can also be affected, since the increase in solar wind can increase the amount of radiation that can penetrate the plane. Passengers traveling on long-haul flights may be exposed to radiation doses equal to that of a dental x-ray. This also poses an additional risk to flight crews who spend many hours in the air.
In addition, Solar Minimum can increase the effects of space weather and cause the interruption of navigation. technology and communications.
Earlier this year, cameras on board the satellite of NASA's Solar Dynamics Observatory (SDO) captured images of the solar surface that showed an unusual stillness amid the lack of sunspot activity in the magnetic field.
According to NASA's calculations, it was originally predicted that the minimum predicted low point for solar energy would come in 2019 or 2020, but now researchers say that sunspots are disappearing at a much faster rate than anticipated and that the cycle Current solar may end earlier than planned.
Why does the lack of sunspots create interruptions for the Earth?
Inactivity in the sun's magnetic field leads to a decrease, or even cessation, of sunspot activity. Throughout the average solar cycle of eleven years, there are periods known as Maximum Solar, with more activity, and Solar Minimum, with little or no activity.
While sunspots and solar flares decrease during the Minimum, the long-lived phenomenon, such as coronal holes, is expected to increase. Coronal holes are produced when the star's magnetic field opens into space, creating fast-moving solar winds. As the sun's magnetic field becomes less active, solar winds become more frequent and begin to bombard the Earth. Coronal holes allow charged particles to enter the solar system, hitting the planet's atmosphere.
This results in complications such as magnetic storms, affects satellite operations, causes fluctuations in the electrical network and can also affect the migration pattern of the animals.
With all these potential problems that can be caused by the fall of solar activity, people should be aware and cautious.
