The research scientists have noted that the change in temperature of the ocean waters at the mouthof the Jakobshavn Isbrae Glacier has caused the velocity and melt rate for the glacier to change overthe last few years. The glacier’s maximum velocity due to warm ocean waters occurred in 2013 a yearafter the impact of the debris stream of a supernova, SN1006. The supernova was observed explodingin 1006AD and debris from the explosion impacted Earth in 2010. The eastern terminus, ET, of SN1006provides energy input to the ocean and area near the mouth of the glacier on May 2 of every year afterimpact and this energy cause the warm up for the waters surrounding the glacier, global warming. Intime, the strength of the impact stream wanes and the glacier begins to refreeze, global cooling
