In this week’s Roundup, GlacierHub reports out from AGU 100, exploring a basis for calling the Himalayas the Third Pole, and what a rising Lake Superior means for Duluth.
Smoke and dust from bushfires in Australia have crossed the Tasman Sea and settled on glaciers in New Zealand. This coating of ash threatens New Zealand’s glaciers by increasing melting. It also highlights the severity of Australia’s bushfires.
As a climate threat, sea level rise has been well-documented. However, it’s rising lake levels, linked to the warming climate, that may be threatening the shores of Duluth, Minnesota, a city recognized for its climate-safe attributes and that is being advertised as a safe haven for climate refugees.
The physical geography of the Arctic Ocean is evolving as climate change causes ice melt to reveal new islands and waterways in remote areas near the North Pole. The exposure of this new frontier will alter the behavior of Russia’s strategic militaristic forces as well as shift the geopolitical environment of the region in terms of shipping and resource extraction.
Former GlacierHub writer Sam Inglis shares a video of a debris fall from a glacier on a traverse of the Ganja La in Nepal. The region’s 56,000 glaciers are melting into a high mountain land of unstable lakes.
The World Meteorological Organization convened a three-day summit to identify priority actions to support more sustainable development, disaster risk reduction, and climate change adaptation in high-mountain areas and downstream.
Scientists from the Lamont-Doherty Earth Observatory travel the world each year for the purposes of their research. An exhibition displaying their photographs provides a glimpse into a fragile world that few get the opportunity to see.
The World Meteorological Organization released a video detailing changes high mountain ecosystems are undergoing as a result of global climate change. This video announced the High Mountain Summit, which convened in Geneva, Switzerland last week.
In Grand Teton National Park, two groups of researchers are investigating glaciers from different, but complimentary perspectives. National Park Service scientists are tracking glacial melt on five of the park’s eleven glaciers while Washington State University biologist, Scott Hotaling, examines the effects of glacial meltwater on the microbiota downstream.
The European Space Agency (ESA) released a video this past week showing the evolution of two very large and disconcerting cracks in Antarctica’s Pine Island Glacier. They have each grown to 20km in length and could shear off a hunk of ice the size of Paris and Manhattan combined.
Melting glaciers are threatening Aoraki/Mount Cook National Park in New Zealand. A new study examines the impacts of receding glaciers on geotourism and visitor experience within the park.
