Several errors in just those two sentences ...
Gee. And the “article puts to rest the whole sun-warming theory”, eh? And article written by, as larrylib so eloquently puts it, “by professionals.” Who are not “in it for the money or idealism” (unlike everybody else in the global warming crowd), but who do charge very high prices for their product. Gee. Who would have thought?
See, I understood that the EARTH’S magnetic field helped shield us from the SUN’S (and other star’s!) cosmic rays, (note that the earth’s magnetic field is reducing and moving as we apparently are swapping north magnetic poles again!), and that the cosmic ray-influence on cloud formation tracks very, very closely with measured temperatures over the past 30 years.
See, what the original sun-level studies measured (what MIGHT be measured in this study- we can’t tell because the greedy scientists won’t tell us!) was solar (visible) radiation, not solar & stellar cosmic ray radiation.
While CO2 levels don’t track (they precede temperature changes) temperatures at all. Even in the short terms trends, CO2 levels don’t track with temperatures: temps for 8 years have declined since 1998’s peak, but CO2 levels have steadily risen as India, Brazil, Indochina, and China continue to pollute.
Note that 1998’s peak matched a solar radiation/cosmic ray peak, but not anything else.
CO2 does track temperature. Higher temperature forces outgassing of CO2 from the largest volatile resource of CO2 on earth - the oceans. The lag between temp change and CO2 outgassing from the bulk of the ocean is an average of 800 years (see my post 31 for a neat graph of this behaviour).
Its this ~ 800 yr lag which makes the picture so fuzzy. It was hot in 1200 AD, so CO2 from outgassing is peaking now!
But the ocean lag depends on ocean depth, so the CO2 "echo" from high temperatures in 1200 comes back over a range of centuries, not as a clear spike 800 years later. Very confusing and hard to read. And it renders 25 yr "snapshot" experiments more or less useless.
The Earth's field protects from cosmic rays. The Sun also has a magnetic field that deflects extra-solar cosmic rays. The galaxy also has a magnetic field that helps deflect extra-galactic cosmic rays, and the degree of protection we get from that varies as the sun orbits the galaxy (the sun's galactic orbit brings it deep into the field and peeks us out of the field on a long cycle)
Depending on how important each field is, we may see very complicated cycles
