"MAJOR FLARE WARNING: Sunspot AR2860 is big, angry, and it's directly facing Earth. The active region just unleashed a significant M4.7-class solar flare (Aug. 28 @ 0611 UT), probably hurling a CME toward Earth: movie. If current trends continue, a major X-flare could be in the offing, so stay tuned."

Just noted this bit... Increased cloud cover can cool the planet in the longer period due to increased albedo constant.
Now that Solar Minimum has passed, the sun is waking up again. Solar magnetic fields are strengthening, providing a stiffer barrier to cosmic rays trying to enter the solar system. The decline of cosmic radiation above California is a sign that new Solar Cycle 25 is gaining strength.
.Who cares? Cosmic rays are a surprisingly "down to Earth" form of space weather. They can seed clouds, trigger lightning, and penetrate commercial airplanes. According to a study from the Harvard T.H. Chan school of public health, crews of aircraft have higher rates of cancer than the general population. The researchers listed cosmic rays, irregular sleep habits, and chemical contaminants as leading risk factors. Somewhat more controversial studies ( #1, #2, #3, #4) llink cosmic rays with cardiac arrhythmias and sudden cardiac death.
Just noting the clouds bit.

In fact I see most of the Albedo monitoring web sites are way out of date....

Some sort of update would be handy, if available. |
