The sun is spotless again!

The sun is once again spotless after a period of 10 days or so of sunspots present.

Spotless sun

The current solar minimum continues and the level of activity from the sun remains very low. So what does this mean for us? Well, colder and colder weather is on the way this winter.

There is one school of thought out there that suggests that the solar winds directly impact the generation of clouds in the Earth’s atmosphere. The higher the solar winds, then the less clouds are generated resulting in higher temperatures in Earth’s atmosphere. If high solar winds mean more clouds then the converse would mean that the lower the solar winds, the more clouds are formed which would reflect the sun’s energy and result in lower temperatures.

When the Sun is active, its magnetic field is better at shielding us against the cosmic rays coming from outer space, before they reach our planet. By regulating the Earth’s cloud cover, the Sun can turn the temperature up and down. High solar activity means fewer clouds and and a warmer world. Low solar activity and poorer shielding against cosmic rays result in increased cloud cover and hence a cooling. As the Sun’s magnetism doubled in strength during the 20th century, this natural mechanism may be responsible for a large part of global warming seen then. …Read the rest of the article

Right now solar winds are a minimum and cosmic rays are at record highs. Here is a good article on cosmic rays.

This theory seems more plausible than the idea that more and more CO2, generated by man, is driving up temperatures due to greenhouse warming effects. I believe that we are heading toward much cooler temperatures in the coming months and I think that the sun is the key.
