The GlacierHub News Report is a bi-monthly video news report that features some of our website’s top stories. This week, GlacierHub news is featuring an interview with Sophie Elixhauser, a new study on the Atlantic Meridional Overturning Circulation, a discussion of hazardous development in Nepal, and a theory about snowballs and slushies!

East Greenland’s Iivit Communities: An Interview with Sophie Elixhauser
By: Natalie Belew
Summary: GlacierHub interviewed anthropologist Sophie Elixhauser to discuss her recently published book, “Negotiating Personal Autonomy: Communication and Personhood in East Greenland.” She shared her perspective of her time observing the Inuits in East Greenland. She explained that she began her research in East Greenland with a very broad question about how people relate to their environment.

A New Low for the Atlantic Meridional Overturning Circulation
By: Sabrina Ho
Summary: A new paper published in Nature has shown that the Atlantic Meridional Overturning Circulation has decreased drastically in strength, especially in the last 150 years. Increasing freshwater input from melting glaciers and ice sheets in the Nordic and Arctic Seas have contributed to the slowdown. GlacierHub interviewed Wallace Broecker, a well-known geoscience professor in Columbia University’s Department of Earth and Environmental Sciences who coined the term “the great ocean conveyor belt.” He claims that there are dozens of “water hosing experiments” that simulated freshwater input of higher magnitudes coming from Greenland. “Still they failed to shut down the AMOC,” he said.

Communities in Nepal Expand to Risk Areas, Despite Hazards
By: Jade Payne
Summary: A recently published study in the journal Land has found that more than a quarter of the new houses in Pokhara, the second-largest city in Nepal, are being built in highly dangerous areas susceptible to multiple natural hazards, including glacier lake outburst floods (GLOFs) and avalanches. The study lists a number of challenges for this rapidly-growing city, located in a region with a number of geological hazards. Most of the newly settled areas are located in agricultural areas, which are attractive to prospective residents because they are flat and have owners who permit construction. However, these locations place new houses at great risk. The researchers indicate that this growth will continue until at least 2035.

Was the Earth Frozen Solid
By: Tae Hamm
Summary: Many scientists are coming up with hypotheses about a global ice age during the Cryogenian geologic period that took place between 720 to 635 million years ago. Two main hypotheses are on the table: “Snowball Earth” theory, which argues that ice covered the entire Earth, and “Slushball Earth” hypothesis, where the sea near the equator stayed open, allowing the evaporation and precipitation of water to persist. However, neither of these hypotheses are set in stone, but are rather part of an ongoing debate that requires much clarification. Developing different climate models with many parameters is necessary to better understand what happened during the Cryogenian period, giving flexibility to the ever-unknown complexity of past climate conditions. Moreover, careful study of the organisms that survived during this period could further help us understand the truth behind the Cryogenian ice age.
