How do sunspots affect global warming? i know that they%26#039;re linked to cmic rays, but how%26gt;
please be as clear as possible as im having real problems with this
lol
thnx

• The way I understand it has some holes, but here goes. The earth has a magnetosphere. It is produced by liquid metallic outer core. The Earth%26#039;s magnetosphere deflects many cosmic rays. Cosmic rays theoretically help produce water droplets from water vapor. The sun also has a magnetosphere but many magnitudes stronger than the earth%26#039;s. I believe it is formed from %26quot;metallic%26quot; hydrogen eddies in the sun%26#039;s interior but not absolutely sure about that. In any event, the sun goes through various cycles that increase and decrease its total output. At times when the sun is producing lots of radiation, it tends to have more sun spots. The sun spots are like magnetic storms. Sometimes they can produce flares that interfere with the Earth%26#039;s magnetosphere. Perhaps this is why there is a 11 year warming and cooling cycle that seems to go beyond what you would expect from just measuring the solar output. 9% 1 Vote 0% 0 Votes
  
  %26quot;there is little evidence for any solar variability in irradiance that is not related to the shielding/enhancements of sunspots and faculae - which implies only a modest decrease in solar flux at the Maunder Minimum%26quot;
  
  And here%26#039;s the scientific paper which showed conclusively there is no significant link:

• Something that might undermine sunspots, could be corona projections. Very little if nothing is understood about them.
  
  Sunspots are expressed in order of magnitude and cycles. Nether are truly predictable, and NASA knows it%26#039;s something to be concerned over. 36% 4 Votes
