(PhysOrg.com) -- The magnetic north pole is slowly moving, and the shift is affecting runways at airports in Tampa, Florida, with the major runway at Tampa International Airport closed until January 13th to allow for the ...
(PhysOrg.com) -- The Earth's magnetic poles flip around every 200,000 years or so, with north becoming south and vice versa. Normally, the process takes 4-5,000 years and it ought to be impossible for the flip to be much ...
The temporary breakdown of Earth's magnetic field 42,000 years ago sparked major climate shifts that led to global environmental change and mass extinctions, a new international study co-led by UNSW Sydney and the South Australian ...
