New evidence suggests that high-energy particles from space known as galactic cosmic rays affect the Earth's climate by increasing cloud cover, causing an "umbrella effect."

When galactic cosmic rays increased during the Earth's last geomagnetic reversal transition 780,000 years ago, the umbrella effect of low-cloud cover led to high atmospheric pressure in Siberia, causing the East Asian winter monsoon to become stronger. This is evidence that galactic cosmic rays influence changes in the Earth's climate. The findings were made by a research team led by Professor Masayuki Hyodo (Research Center for Inland Seas, Kobe University) and published on June 28 in the online edition of Scientific Reports.

The Svensmark Effect is a hypothesis that galactic cosmic rays induce low cloud formation and influence the Earth's climate. Tests based on recent meteorological observation data only show minute changes in the amounts of galactic cosmic rays and cloud cover, making it hard to prove this theory. However, during the last geomagnetic reversal transition, when the amount of galactic cosmic rays increased dramatically, there was also a large increase in cloud cover, so it should be possible to detect the impact of cosmic rays on climate at a higher sensitivity.

    Easy and simple, as nature likes to do.
    Magnetic poles (finally) flip over, cooling effect ensues, cancels mankind's "global warming" fiasco. People can continue flying jets everywhere and pounding the atmosphere with more rocket launches. Your car - negligible impact - just a lot of political hot air. Your clean rivers - good; but look at China, India, etc. THAT is whgere the problem lies and we keep on buying their stuff....

    Even though that was funny, I have to object that there's an order of magnitude problem here. The two factors may oppose, but one is so much stronger than the other that the secondary one will be overridden...and we'll keep getting warmer.

    Unfortunately, I've seen argument as silly as that one (the parent's) taken seriously.
