Recently��global earthquakes occur frequently��which may be caused by geomagnetic weakening�� The study showed that the reasons of geomagnetic weakening were the increase of crust-mantle rotatioanal inertia and the reduction of earth rotation led by polar ices melting��which caused the change of core-mantle differential ro tation on numerical value and direction��During the process of geomagnetic weakening and polarity reversal��the increase of solar radiation and the release of core-mantle thermal energy were in one-to-one correspondence with disasters��This conclusion was consistent to the "shallow core field" discovered by American scholars��The correlation of global warming to geomagnetic weakening showed that climate warming not only caused sea level rise��but also led to frequent earthquakes and volcanic activities��
