Greta will blame this on fossil fuel use…
Sunspot activity on the surface of the Sun follows a well-known but little understood 11 year cycle. Activity rises and falls creating the so-called solar maximum and then solar minimum. During a solar maximum, the Sun is more powerful and is littered with sunspots.
Conversely when the Sun enters a solar minimum – which it did about two years ago – energy from our host star begins to lessen.
However, one expert has warned that the Sun will enter a period of “hibernation” this year, in what as known as a Grand Solar Minimum (GSM).
…the Sun’s hibernation period could last for three decades, which will lead to wetter and colder summers.
Prof Zharkova told The Sun: “The Sun is approaching a hibernation period. “Less sunspots will be formed on the solar surface and thus less energy and radiation will be emitted towards the planets and the Earth. The reduction in temperature will result in cold weathers on Earth, wet and cold summers, cold and wet winters.”
Here, the International Space Station transits a spotless sun:
