Cold weather warning: Atmosphere SHRINKS as sun cools down for solar minimum

PART of the Earth’s atmosphere is shrinking and cooling as the sun gives off less heat as our host star enters the solar minimum.

The sun has now entered a “deep solar minimum” now and Earth could be in for a very long period of cold temperatures.

The sun follows cycles of roughly 11 years where it reaches a solar maximum and then a solar minimum.

During a solar maximum, the sun gives off more heat and is littered with sunspots. Less heat in a solar minimum is due to a decrease in magnetic waves.

Scientists are adamant we are now entering the solar minimum as part of the sun’s atmosphere is shrinking.

This happens every time the sun changes cycle – when it enters a solar minimum, the thermosphere contracts, and during a solar maximum it expands to give better protection agains solar rays.

Website Space Weather states: “The sun is entering a deep Solar Minimum, and Earth's upper atmosphere is responding.

“Data from NASA's TIMED satellite show that the thermosphere (the uppermost layer of air around our planet) is cooling and shrinking, literally decreasing the radius of the atmosphere.”
