Northern permafrost region emits more greenhouse gases than it captures, study finds
2024-04-15 in Phys.org - News and Articles on Science and TechnologyPermafrost underlies about 14 million square kilometers of land in and around the Arctic. The top 3 meters contain an estimated 1 trillion metric tons of carbon and 55 billion metric tons of nitrogen. Historically, the northern permafrost region has been a sink for carbon, as frozen soils inhibit microbial decomposition. But rising temperatures contribute to thawing permafrost and enhance the biogeochemical activities that exacerbate climate change by releasing greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

European summer weather linked to North Atlantic freshwater anomalies in preceding years
2024-03-14 (or before) in wcd.copernicus.orgAbstract. Amplified Arctic ice loss in recent decades has been linked to the increased occurrence of extreme mid-latitude weather. The underlying mechanisms remain elusive, however. One potential link occurs through the ocean as the loss of sea ice and glacial ice leads to increased freshwater fluxes into the ocean. Thus, in this study, we examine the link between North Atlantic freshwater anomalies and European summer weather. Combining a comprehensive set of observational products, we show that stronger freshwater anomalies are associated with a sharper sea surface temperature front between the subpolar and the subtropical Nor...

Manifestation of Gas Seepage from Bottom Sediments on the Sea Surface: Theoretical Model and Experimental Observations
2024-01-20 in MDPI - Publisher of Open Access JournalsThe key area of the Arctic Ocean for atmospheric venting of CH4 is the East Siberian Arctic Shelf (ESAS). Leakage of methane through shallow ESAS waters needs to be considered in interactions between the biogeosphere and a warming Arctic climate. The development of remote sensing techniques for gas seepage detection and mapping is crucially needed for further applications in the ESAS and other areas of interest. Given the extent of the seepage areas and the magnitude of current and potential future emissions, new approaches are required to effectively, rapidly, and quantitatively survey the large seepage areas. Here, we consider...

Effect of Wind Speed and Leads on Clear-Sky Cooling over Arctic Sea Ice during Polar Night
2023-12-27 (or before) in American Meteorological Society JournalsAbstract A simple analytical model of the atmospheric boundary layer (ABL) coupled to sea ice is presented. It describes clear-sky cooling over sea ice during polar night in the presence of leads. The model solutions show that the sea ice concentration and wind speed have a strong impact on the thermal regime over sea ice. Leads cause both a warming of the ABL and an increase of stability over sea ice. The model describes a sharp ABL transition from a weakly stable coupled state to a strongly stable decoupled state when wind speed is decreasing. The threshold value of the transition wind speed is a function of sea ice concentrat...

An earth system model shows self-sustained thawing of permafrost even if all man-made GHG emissions stop in 2020 - Scientific Reports

Recently, there have been warnings that some of these tipping points are coming closer and are too dangerous to be disregarded. In this paper we report that in the ESCIMO climate model the world is already past a point-of-no-return for global warming. In ESCIMO we observe self-sustained thawing of the permafrost for hundreds of years, even if global society stops all emissions of man-made GHGs immediately. We encourage other model builders to explore our discovery in their (bigger) models, and report on their...

Subsea Methane Hydrates: Origin and Monitoring the Impacts of Global Warming
2022-11-23 in MDPI - Publisher of Open Access JournalsThe East Siberian Arctic shelf is the area where the largest natural gas reserves are concentrated. The formation of permafrost of the Arctic shelf during the Ice Age contributed to the emergence of a zone of stable existence of gas hydrates in the sedimentary layer, and subsequent flooding of the shelf led to its gradual degradation, the thawing of gas hydrates and the subsequent emissions of methane into the atmosphere. In the first part of the paper, we use mathematical modeling to study the processes of the formation of subsea permafrost on the Arctic shelf considering changes in the sea levels over the past 200 thousand yea...

Exceptional warming over the Barents area - Scientific Reports
2022-06-15 (or before) in NatureIn recent decades, surface air temperature (SAT) data from Global reanalyses points to maximum warming over the northern Barents area. However, a scarcity of observations hampers the confidence of reanalyses in this Arctic hotspot region. Here, we study the warming over the past 20–40 years based on new available SAT observations and a quality controlled comprehensive SAT dataset from the northern archipelagos in the Barents Sea. We identify a statistically significant record-high annual warming of up to 2.7 °C per decade, with a maximum in autumn of up to 4.0 °C per decade. Our results a...

Caribou and reindeer migrations in the changing Arctic
2021-10-05 in De Gruyter Academic PublishingCaribou and reindeer, Rangifer tarandus , are the most numerous and socio-ecologically important terrestrial species in the Arctic. Their migrations are directly and indirectly affected by the seasonal nature of the northernmost regions, human development and population size; all of which are impacted by climate change. We review the most critical drivers of Rangifer migration and how a rapidly changing Arctic may affect them. In order to conserve large Rangifer populations, they must be allowed free passage along their migratory routes to reach seasonal ranges. We also provide some pragmatic ideas to help conserve Rangifer migr...

On avoiding dangerous anthropogenic interference with the climate system: Formidable challenges ahead
2021-07-04 (or before) in PNAS - Proceedings of the National Academy of ScienceThe observed increase in the concentration of greenhouse gases (GHGs) since the preindustrial era has most likely committed the world to a warming of 2.4°C (1.4°C to 4.3°C) above the preindustrial surface temperatures. The committed warming is inferred from the most recent Intergovernmental Panel on Climate Change (IPCC) estimates of the greenhouse forcing and climate sensitivity. The estimated warming of 2.4°C is the equilibrium warming above preindustrial temperatures that the world will observe even if GHG concentrations are held fixed at their 2005 concentration levels but without any other anthropogenic forc...

The two predominant mass loss mechanisms are increased surface meltwater run-off and mass loss associated with the retreat of marine-terminating outlet glaciers. In this paper we use a large ensemble of Greenland ice sheet models forced by output from a representative subset of the Coupled Model Intercomparison Project (CMIP5) global climate models to project ice sheet changes and ...

Harvard chemist: Permafrost N2O levels 12 times higher than expected
2019-06-06 in Harvard GazetteA recent study shows that nitrous-oxide emissions from thawing Alaskan permafrost are about 12 times higher than previously assumed. About a quarter of the Northern Hemisphere is covered in permafrost, which is thawing at an increasing rate. And, even though researchers are monitoring carbon dioxide and methane, no one seems to be monitoring N2O, the most potent greenhouse gas.
