What factors contribute to the accelerated decay of Antarctic sea ice in recent years?
Best insight from top research papers
The accelerated decay of Antarctic sea ice in recent years can be attributed to multiple factors. The decline in sea ice extent (SIE) is influenced by the intensification of atmospheric zonal waves and enhanced poleward transport of warm-moist air, along with anomalous warming in the Southern Ocean mixed layer . Additionally, there has been a decoupling of the surface from the subsurface ocean, with a release of heat from the subsurface contributing to the sea ice decline . Changes in Southern Ocean temperature and subglacial water dynamics have also played a role in the rapid ice response to climate change . Furthermore, the decrease in sea ice is related to the warming trend of 2m air temperature and increased absorbed energy, as well as southward energy transportation . These factors combined have led to the accelerated decay of Antarctic sea ice in recent years.

How long does ice last?4 answersIce longevity varies depending on the environment. In the Southern Ocean, most ice lasts less than a year, with an average thickness of 1 m. In contrast, Arctic Ocean ice can persist for several years with an average thickness of 2 m. Buried ice on spherical bodies 2-3.3 AU from the Sun can last billions of years under specific conditions, such as mean surface temperatures below 145 K and surface properties favoring ice retention. Methamphetamine "ice" can have a high lasting from four to twenty-four hours when smoked. In a structural context, a model estimates the fatigue life of a cylindrical structure interacting with ice, with fatigue life ranging from 7 to 4911 years depending on the conditions and assumptions.
What impact does sea ice have in the antarctica?4 answersSea ice in Antarctica has a significant impact on the polar iron cycle, phytoplankton production, and the climate. The decline in Antarctic sea ice cover has led to a reduction in phytoplankton production, negatively affecting marine ecosystems. The reduction or removal of sea ice in the Arctic also affects the energy budget and climate of the Northern mid-latitudes, leading to changes in heat and radiation fluxes, precipitation, and energy transport. Sea ice in the Arctic acts as a source of dimethyl sulfide (DMS), which can impact the dynamics of summertime Arctic clouds. Additionally, sea ice cover influences the annual production of Arctic benthos, with areas of pronounced sea ice cover resulting in reduced growth rates of bivalves. The disappearance of Arctic sea ice would increase the absorbed solar flux, leading to higher solar absorption at the Arctic Ocean surface.
Who theorized antarctic permanent glaciation?3 answersThe theorization of Antarctic permanent glaciation is attributed to DeConto and Pollard. They proposed a threshold atmospheric CO2 concentration of approximately 780 ppmv for the onset of Antarctic glaciation, based on their ice sheet model and the GENESIS climate model. This threshold was suggested to have been crossed during the Eocene-Oligocene transition around 34 million years ago. However, it is important to note that the timing of this threshold crossing may vary depending on the climate model used and its configuration. Other studies have also investigated the role of tectonic mechanisms, such as closing the Drake Passage and changing the elevation of Antarctica, in Antarctic glaciation. These studies suggest that oceanic heat transport plays a relatively minor role, while lowering the elevation of Antarctica has a larger effect on the likelihood of glacial conditions.
How much has Arctic sea ice declined since 1979?5 answersArctic sea ice has declined since 1979. The multi-channel satellite passive-microwave record shows an overall increase in Antarctic sea ice coverage until 2015, but since then, both hemispheres have experienced losses in sea ice coverage. Using a long-term time series of sea ice products from satellite observations, it is found that the Arctic has become less ice-covered in all seasons, especially in summer and autumn. Arctic sea ice thickness has decreased by approximately 52% from 1982 to 2020, and Arctic sea ice volume has decreased by approximately 63% during the same period. These trends are further supported by the classification of the Arctic Ocean into open water, perennial, and seasonal sea ice-covered areas based on sea ice persistence. The loss of the perennial sea ice-covered area is a major factor in the total sea ice loss in all seasons.
Can microplastics degrade further in ice?5 answersMicroplastics (MPs) can degrade further in ice. Researchers have discovered that MPs, such as polystyrene (PS), can be rapidly degraded in frozen environments, with the degradation rate in ice (-20 °C) being surprisingly competitive to most artificial technologies. The degradation process occurs when PS particles are trapped and squeezed in the narrow space of the liquid layer between ice crystals, leading to the production of excited state PS molecules (3 PS*). These excited state molecules then react with highly concentrated dioxygen to selectively produce singlet oxygen (1 O2), which further boosts the oxidizing process and accelerates the degradation of the MPs. This finding not only provides a highly efficient pathway for degrading MPs but also sheds light on the unusual disposal of MPs in nature.
Wahts is the creep failure behaivour of ice and how can it be described?5 answersCreep failure behavior of ice refers to the time-dependent deformation and breakdown of ice under relatively low stresses. It can be described using various models and frameworks. One model is based on the combined finite-discrete element method, where the ice sheet is represented by polyhedral rigid discrete elements joined by Timoshenko beam elements. Another model takes into account the effect of pressure on the rheological parameters of ice in creep, and fits the physical parameters with experimental data for elongational flow of ice samples. A simple model for creep failure of disordered solids, which reproduces experimental observations, shows power laws for strain rate and log-normal distribution for creep lifetime. The increased temperature sensitivity of ice's constitutive behavior near the melting point is quantified using dislocation mechanics. These models and frameworks contribute to understanding the creep failure behavior of ice and its implications in various applications.
