global mean temperature galactic cosmic ray flux solar minimum magnetosphere sun spot correlation..

Cosmic ray flux on Earth has only been monitored since 1950 but since 1990, galactic cosmic ray flux detected on Earth has changed in the opposite direction to that required to explain away the observed rise in global mean temperatures
so their is no significant trend correlation over that period concerning temperature

The magnetic poles are where the magnetic fields are the strongest, Changes in Earth's magnetic field on a time scale of a year or more are referred to as secular variation. Over hundreds of years, magnetic declination is observed to vary over tens of degrees

WARNING! Watts Up With That , Anthony Watts climate change denial blog in opposition to the scientific consensus on climate change is shit!
