This week saw the conclusion the UiO International Summer School course "A Changing Arctic". The annual 6 week course is a blend of social science, law, and natural science lectures, and this year saw 13 students from a range of professional backgrounds and nationalities attend. As in previous years, CEED is heavily involved in the program; Carmen Gaina is course leader and a lecturer, course assistant is Grace Shephard, and this year's line-up included a lecture from Anne Hope Jahren

According to a new study is the global sea level rising faster than previously thought. The accelerating sea level will have impact on coastlines around the world.  Several of the World’s largest cities are near a coastline, here New York. For others see U.N. Atlas of the Oceans.  Illustration photo: Colourbox.com

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.

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.

Mauritius is best known as a tropical holiday paradise island in the Indian Ocean, but for an Earth Science research team led by Professor Trond H. Torsvik it is piece of a geological puzzle. Now they have found a new fragment of an ancient continental crust beneath the young, but inactive volcanoes on the island.
