What's Normal in a Changing Arctic Climate?

"Is Updating Once a Decade Enough?
Part of the impetus for updated baseline every ten years is to keep up with the changing climate. The Arctic though is warming so fast that this once-a-decade update is not sufficient to keep up the pace of change." https://alaskaclimate.substack.com/p/whats-normal-in-a-changing-arctic From Rick Thoman @AlaskaWx
The nuclear legacy of the Russian Arctic
"The nuclear legacy in the north-west of Russia includes the building of a former military base in Andreyeva Bay, spent nuclear fuel from nuclear submarines, sunken nuclear and radiation hazardous objects at the bottom of the Arctic sea" https://bellona.org/publication/nuclear-legacy-arctic#Arctic#Cryosphere#Nuclear#Russia
Gustaf Hugelius on thawing permafrost
Gustaf Hugelius, Professor at the Department of Physical Geography and Vice Director of the Bolin Centre of Climate Research, gives a talk about the global carbon cycle, how thawing permafrost affects the global climate, ecosystems and Arctic peoples. https://www.youtube.com/watch?v=hO-6x7waPNY#Permafrost#Cryosphere
Predicting greenhouse gas fluxes to the atmosphere from thawing permafrost
"Abstract: Arctic permafrost is thawing at rapid rates, which threatens to expose large stores of soil organic carbon to microbial degradation" https://www.youtube.com/watch?v=d4tBmBbY5mg#Permafrost#Arctic#Cryosphere

Ocean currents threaten to collapse Antarctic ice shelves
"Our findings challenge conventional wisdom," Nakayama says. "Our study underscores that the interplay between meandering ocean currents and the ocean floor generates upwelling velocity, bringing warm water to shallower depths. Subsequently, this warm water reaches the ice-ocean interface, accelerating ice shelf melting
Four decades of glacial data reveals substantial losses and water worries
An analysis of glacial data spanning four decades has provided valuable insights into the changes taking place in the #glaciers of the Pir Panjal range within the #Kashmir basin in India. The research, published in the International Journal of Hydrology Science and Technology, analyzed data for the period 1980 to 2020.
It reveals significant losses in glacial mass.
Rapid melting of ice sheets and glaciers drives a unique geometry, or fingerprint, of sea level change. As an ice sheet loses mass, its gravitational attraction on the nearby ocean is reduced, causing ocean water to migrate away from the ice sheet. https://www.youtube.com/watch?v=lD_t-7YQnO8#SeaLevelRise#Glaciers#Cryosphere

Study reports enormous ice loss from Greenland glacier "Ground-based measuring devices and aircraft radar operated in the far northeast of Greenland show how much ice the 79° N-Glacier is losing. According to measurements conducted by the Alfred Wegener Institute, the thickness of the glacier has decreased by more than 160 meters since 1998. Warm ocean water flowing under the glacier tongue is melting the ice from below" https://phys.org/news/2024-03-enormous-ice-loss-greenland-glacier.html#Greenland#Glaciers#Cryosphere#SeaLevelRise
