The mind-bending mystery of the Hawaiian-Emperor Bend
June 28, 2017 9:39 PM
The Hawaiian-Emperor volcanic island chain in the NW Pacific Ocean is well known for its peculiar 60° bend. This bend has been heavily debated for decades. Researchers from University of Oslo, GFZ Potsdam, and Utrecht University now definitely demonstrate that to form the observed bend requires an abrupt change in the motion of the Pacific tectonic plate, while southward drift of the mantle plume that has sourced the chain since ~80 Ma is required to explain its entire 2000 km length.
Global mean sea level rise accelerates faster than previously thought

Across the globe, sea level has been rising for decades, but we don’t know how fast. Researchers have now analyzed tide gauge data and reconstructed global mean sea level since 1902. Their record yields a slower average rise before 1990 than previously thought, but similar high rates of about 3.1 mm/yr as observed from independent satellite observations from 1993-2012. This suggests that global mean sea level has been accelerating much faster than previously assumed in the past two decades.
