Sunspots Vanish and Cosmic Rays Increase, Will Cooling Follow?

SPACE WEATHER: So far in 2017, the big story in space weather is sunspots–or rather, the lack thereof. The sun has been blank more than 90% of the time. Only one very tiny spot observed for a few hours on Jan. 3rd interrupted a string of spotless days from New Years through Jan.11th. Devoid of dark cores, yesterday’s sun is typical of the year so far:

A lot of interesting things happen when sunspots vanish. For instance, the extreme ultraviolet output of the sun plummets. This causes the upper atmosphere of Earth to cool and collapse. With less air “up there” to cause orbital decay, space junk accumulates around our planet.

Also during Solar Minimum, the heliosphere shrinks, bringing interstellar space closer to Earth. Galactic cosmic rays penetrate the inner solar system with relative ease. Indeed, a cosmic ray surge is already underway, with implications for astronauts and even ordinary air travelers.

There is growing evidence that cosmic rays can increase the planet’s cloud cover, resulting in planetary cooling. With a surge in cosmic rays,  can we anticipate increased cloud cover, resulting in temperature decline?  The real question is how much?
