With news breaking that Alaska just had its warmest March to May on record with a statewide average temperature of 32.6°F, 8.6°F above the long-term average – the previous warmest spring in Alaska was in 2016, one must ask how this performs in relation to seismicity. First we learn that according to the University of…
Exciting polar bear cam b-roll USGS footage from the bear’s perspective from 2014, 2015, and 2016. The USGS Alaska Science Center Polar Bear Research Project conducts long-term research on polar bears to inform, local, state, national and international policy makers regarding conservation and management of the species and its habitat. The USGS’s studies are primarily…
Volcanism triggered by deglacial unloading may plausibly accelerate melting and water runoff through an albedo effect of dark tephra on snow and ice. http://www.sciencedirect.com/science/article/pii/S0012821X16303892
This is climate change: Alaskan villagers struggle as island is chewed up by the sea In this town of 403 residents 83 miles above the Arctic Circle, beaches are disappearing, ice is melting, temperatures are rising, and the barrier reef Kivalina calls home gets smaller and smaller with every storm. There is no space left…
The U.S. Geological Survey Gas Hydrates Project Release URL | Access date: January 3rd 2014. Climate studies in the USGS Gas Hydrates Project have become increasingly important since 2007 and focus on the impact of Late Pleistocene to contemporary climate change on the stability of methane hydrate deposits. The goal is to determine how much, if any,…
By Joe Romm / Climate Progress – on Jun 13, 2013: A NASA science team has observed “amazing and potentially troubling” levels of methane and CO2 from the rapidly warming Arctic. Given the staggering amount of carbon trapped in the permafrost — and the fact that methane is a very potent heat-trapping gas — the…
Five Myths About Arctic Sea Ice http://sites.agu.org/sharingscience/f… Changes in Arctic sea ice coverage are happening at unprecedented rates, with 2012 setting a new record low for sea ice extent. Our ability to predict changes of sea ice loss and understand the impacts on society, from commercial shipping to resource availability, will be driven by further…
Release of 14C-depleted methane to the atmosphere from abundant gas seeps concentrated along boundaries of permafrost thaw and receding glaciers in Alaska and Greenland Nature Geoscience (2012) Abstract Methane, a potent greenhouse gas, accumulates in subsurface hydrocarbon reservoirs, such as coal beds and natural gas deposits. In the Arctic, permafrost and glaciers form a ‘cryosphere…
