Weakening of Earth's magnetic field is a harbinger of increase in frequency and severity of natural disasters. Changes in the tension of Earth’s magnetic field are happening unevenly along the surface and reach maximum values in the Western Hemisphere, particularly in North and South America. This suggests that on these territories the strongest disasters should be expected in the coming years. http://allatra-science.org/en/publica...
