Earth's Magnetic pole

National Centers for Environmental Information (NCEI) scientists have updated the world magnetic model (WMM) mid-cycle, as Earth’s northern magnetic pole has begun shifting quickly away from the Canadian Arctic and toward Siberia, an NCEI report said this week. The new WMM more accurately represents the change of the magnetic field since 2015. The alteration could have an impact on government, industry, and consumer electronics.
“Due to unplanned variations in the Arctic region, scientists have released a new model to more accurately represent the change of the magnetic field,” the report said, noting that updated versions of the WMM are typically released every 5 years. This update comes about 1 year early.
“This out-of-cycle update before next year’s official release of WMM 2020 will ensure safe navigation for military applications, commercial airlines, search and rescue operations, and others operating around the North Pole,” said NCEI, which is part of the National Oceanographic and Atmospheric Administration (NOAA). “Organizations such as NASA, the Federal Aviation Administration, US Forest Service, and many more use this technology. The military uses the WMM for undersea and aircraft navigation, parachute deployment, and more.”
