Back-to-back geomagnetic storms raise Earth’s atmospheric temperature to the highest level in 20 years.
According to Space, Earth’s atmosphere recently hit a new temperature record, having recently absorbed energy from intense solar storms (or geomagnetic storms).

Martin Mlynczak, researcher of the ƬIMED mission at the ASA research center, said: “The Thermosphere Climate Index (TCI.)) peaked on March 10, peaking at 0.24 TW (Note: 1 TW equals 1 trillion watts). It is known that the last time the TCI was so high was on December 28, 2003.
According to this expert, the reason for the sudden increase in the temperature of the earth’s atmosphere is due to three geomagnetic storms that occurred in January and February and caused great disturbances in the earth’s magnetic field.
These storms build up energy in the ionosphere, Mlynczak said, which then heats it up by increasing levels of infrared emissions of nitric oxide and carbon dioxide.
Normally, infrared radiation after a solar storm cools the ionosphere, but due to subsequent storms, the temperature has always remained high and not reduced.
Since the temperature of the atmosphere has increased, at least two other geomagnetic storms have hit our planet. A storm occurred on March 24, the strongest storm to hit land in over 6 years. Another storm occurred on April 24.

Scientists from the US National Oceanic and Atmospheric Administration (NOAA) have predicted that the next solar peak will occur in 2025.
This means that the warming trend of the atmosphere is expected to continue over the next few years, causing effects on the functioning of satellites orbiting the Earth.
“The thermosphere expands as it heats, causing increased aerodynamic drag on all satellites, as well as space debris.”explains Mlanczak. “It could bring satellites closer to Earth, colliding them or knocking them out of orbit.”
The same thing happened to SpaceX Starlink satellites in February 2022 after a sudden geomagnetic storm.
