Explanation: Our Sun is becoming a busy place. Only two years ago, the Sun was emerging from a solar minimum so quiet that months would go by without even a single sunspot. In contrast, already this year and well ahead of schedule, our Sun is unusually active, already nearing solar activity levels seen a decade ago during the last solar maximum. Our increasingly active Sun was captured two weeks ago sporting numerous interesting features. The image was recorded in a single color of light called Hydrogen Alpha, color-inverted, and false colored. Spicules carpet much of the Sun's face. The brightening towards the Sun's edges is caused by increased absorption of relatively cool solar gas and called limb darkening. Just outside the Sun's disk, several scintillating prominences protrude, while prominences on the Sun's face are known as filaments and show as light streaks. Magnetically tangled active regions are both dark and light and contain cool sunspots. As our Sun's magnetic field winds toward solar maximum over the next few years, whether the Sun's high activity will continue to increase is unknown.

Somebody do something!

How can we stop global warming unless we do something about the sun?

During every solar cycle, there’s a maximum and a minimum. Over all, the solar irradiance and magnetic activity has been trending downward for the last few cycles.

As with earth’s seasonal weather, the effects are delayed and it’s only from about the mid-2000s where earth average temps have been falling, down about 1.5 degrees F since then. Expect the quiet solar cycles to continue for at least another 2 1/2 cycles, about 30 years, where the temps will continue to degrade toward Maunder LIA conditions.

More average cold, snow, ice, clouds, rain, volcanic activity & earthquakes. Worse, the colder temps mean lower crop yields and scarcer foodstocks, leading to famines.

Our Sun is becoming more active?

That just burns me up.
