Link between global warming and rising sea levels
2024-08-04 (or before) in Science DailyA new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.

Tipping risks from overshooting 1.5 °C can be minimised if warming is swiftly reversed
2024-08-01 (or before) in Potsdam Institute for Climate Impact Research08/01/2024 - Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 °C of global warming after a period of overshoot. A new study published in Nature Communications indicates that this risk can be minimised if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers from the Potsdam Institute for Climate Impact Research (PIK), the International Institute for Applied Systems Analysis (IIASA) and other institutes write. They analysed the tipping risks ...

Observational Evidence for a Regime Shift in Summer Antarctic Sea Ice
2024-04-08 (or before) in American Meteorological Society JournalsAbstract In recent years, the Southern Ocean has experienced extremely low sea ice cover in multiple summers. These low events were preceded by a multidecadal positive trend that culminated in record high ice coverage in 2014. This abrupt transition has led some authors to suggest that Antarctic sea ice has undergone a regime shift. In this study we analyze the satellite sea ice record and atmospheric reanalyses to assess the evidence for such a shift. We find that the standard deviation of the summer sea ice record has doubled from 0.31 million km2 in 1979–2006 to 0.76 million km2 for 2007–22. This increased varianc...

The sea-ice cover is instrumental in mediating ocean-atmosphere exchanges and provides an important substrate for organisms from microbes to predators. Antarctic krill, Euphausia superba, are reliant on sea ice during key phases of its life cycle, particularly during the larval stages, as feeding grounds and refuge from their predators, while other small grazers, including copepods and amphipods, either live in the brine channel system or find food and shelter at the ice-water interface and in raf...

Significant West Antarctic Cooling in the Past Two Decades Driven by Tropical Pacific Forcing
2023-11-07 (or before) in American Meteorological Society JournalsAbstract During the second half of the twentieth century, the West Antarctic Ice Sheet (WAIS) has undergone significant warming at more than twice the global mean and thus is regarded as one of the most rapidly warming regions on Earth. However, a reversal of this trend was observed in the 1990s, resulting in regional cooling. In particular, during 1999–2018, the observed annual average surface air temperature had decreased at a statistically significant rate, with the strongest cooling in austral spring. The spring cooling correlates significantly with the second leading modes (EOF2) derived from empirical orthogonal func...

Antarctica's ice shelves could be melting faster than we thought
2022-08-14 (or before) in Phys.org - News and Articles on Science and TechnologyA new model developed by Caltech and JPL researchers suggests that Antarctica's ice shelves may be melting at an accelerated rate, which could eventually contribute to more rapid sea level rise. The model accounts for an often-overlooked narrow ocean current along the Antarctic coast and simulates how rapidly flowing freshwater, melted from the ice shelves, can trap dense warm ocean water at the base of the ice, causing it to warm and melt even more.

During the last 20 years, guideline values for PFAS in drinking water, surface waters and soils have decreased dramatically due to new insights into their toxicity. As a result, the levels in environmental media are now ubiquitously above guideline levels. A perspective article by researchers from Stockholm University and ETH Zurich published in Environmental Science & Technology suggests that PFAS define ...
