I'm pretty sure that this sentence is all f*ck*d up. Its the earth's magnetic field that shields it from the sun's cosmic rays. The earth doesn't produce cosmic rays. At least it didn't when I was in school which admitttedly was a long time ago. Is this a peer reviewed study and who were the peers ?
I think they’re saying that both sun and earth magnetic fields would tend to shunt incoming heavy nuclei aka cosmic rays away from the earth. But in what experimental vessel did anybody ever verify this basic assertion about cosmic rays and clouds?
Your confusing the reporting with the science.
I saw that, I can only assume it was typo, but you would certainly expect better since the topic seems to be closed to further study. You know the alternate theory being so firmly dispensed and all.
Two renowned climatologists named Marx and Lenin, that's who you insolent capitalist pig.
They have a suggestion for an economic policy that will reduce man-made CO2 emissions to almost zero. It calls for a slight modification of the West's socio-economic system, but they are confident that the masses will soon adjust to it as they become more accustomed to wearing leg chains.
The sun also has a magnetic field, which helps to deflect cosmic rays coming from outside the solar system. See this page on Solar magnetic field and cosmic rays
