When ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war warn us about threats to our ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war , we usually hear about climate change, asteroids or nuclear ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war . Now scientists have warned of the ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war of Earth's magnetic poles flipping upside down. The poles are ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war for the magnetic shield around Earth. This protects us from ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war radiation. Life on Earth depends on this shield. Radiation and solar ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war cause a lot of damage. The poles could flip in the next thousand years. This is because the ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war iron revolving around Earth's center is changing ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war . The molten iron acts as a ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war electromagnet. Earth's magnetic poles have flipped ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war 250,000 years. The last time was 780,000 years ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war . The next flip is long overdue. The flip could destroy ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war and power grids; deadly solar ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war could greatly increase rates of cancer; and ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war change could kill many life ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war . Some scientists say a polar flip could blow Earth's atmosphere away. One scientist dismissed any ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war from the poles flipping. He believes any increased ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war would be as harmful as lying on a ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war for a day. He said a "floppy hat" would be ago beach climate communications danger deadly direction enough every existence forms gigantic molten radiation rays responsible scientists threat war to protect us.
