Based on a new scientific report it is estimated that the sun will be cooler and dimmer soon
They believe that there is a cycle among the 11 year cycles, but this other cycle occurs roughly every 400 years (last occurring in the year 1645) called the Maunder Minimum, or grand minimum. During this time, the sun’s surface goes calm and less ultraviolet radiation is is created. Back in 1645 until roughly 1715, there was a grand minimum.
Pictured is the sun when it has surface activity such as sunspots and solar flares. During a solar minimum, the sun's surface becomes almost clear as ultraviolet radiation diminishes
The study titled “Ultraviolet Flux Decrease Under a Grand Minimum from IUE Short-wavelength Observation of Solar Analogs,” was published in Astrophysical Journal Letters. The research states that the sun will be cooler and dimmer by 2050. The decreased activity means far fewer solar flares and sunspots, which equates to much less ultraviolet radiation being flung at Earth. This lower solar activity can affect our planet in different ways including changes in the thickness of the stratospheric ozone layer as well as lower temperatures.
One of the most severe grand solar minimums, named the “Maunder Minimum,” happened between 1645 and 1715. This caused temperatures on Earth to plummet so much that it turned seas into ice. The Baltic Sea was so covered in thick ice in 1658 that it allowed the Swedish army to march across the solid ice to invade Denmark. During the Maunder Minimum, the Thames River froze over in England. However, the cooling was not the same around the globe because the grand solar minimum actually caused warmer temperatures in Alaska and Greenland.
Lubin warns that the decrease in temperatures will not be enough to counter the expected models of climate change. “The cooling effect of a grand minimum is only a fraction of the warming effect caused by the increasing concentration of carbon dioxide in the atmosphere,” a statement from the research team reads. Air temperatures on Earth’s surface would cool by as much as several tenths of a degree according to the study. “A future grand solar minimum could slow down but not stop global warming,” the study claims.
