Nature’s Warning: Early Signs in Marine Life That Predict the Next Mass Extinction

by
SciTechDaily

Researchers have used a detailed global dataset of foraminifera fossils to study shifts in marine community structures before mass extinctions, providing an early warning system for future biodiversity losses due to climate change. Led by Anshuman Swain and Adam Woodhouse, the study highlights the importance of monitoring ecological changes to predict future extinctions, potentially shaping … Read more

Challenging modern climate stories: Forgotten aerial photographs from 1937 expose the Antarctic anomaly

by
SciTechDaily

Researchers from the University of Copenhagen used aerial photographs from 1937 to analyze the stability and growth of the ice in East Antarctica, showing that despite some signs of weakening, the ice has remained largely stable for almost a century, contradicting predictions about sea level rise is improving.

Siberia’s ‘Gateway to Hell’ is rapidly expanding in size, scientists discover

by

A crater in Siberia is expanding faster than expected due to climate change, scientists have discovered, saying it is now causing problems for the surrounding habitat. Known as the ‘Gateway to Hell’ and located in the icy Yana Highlands, the Batagaika slump currently covers about 200 hectares of land and can be seen in satellite … Read more

New water-based heat pump delivers 400% more heat than the energy it consumes

by

A new type of equipment is being trialled at the University of Edinburgh to provide sustainable power to homes and offices in Edinburgh, Scotland. This innovation was developed by SeaWarm, a spin-off company from the University of Edinburgh that harnesses the power of water sources from seas, rivers, ponds and even mine water to efficiently … Read more

The carbon dioxide level in the atmosphere is rising

by

One of the most important drivers of the exceptional heat Building in Earth’s atmosphere has reached levels beyond anything humans have ever experienced, officials announced Thursday. Carbon dioxidethe gas that responsible for most of the global warming caused by human activities is accumulating “faster than ever,” scientists from NOAA, the Scripps Institution of Oceanography and … Read more

Breakthrough ‘miracle material’ for carbon capture: MOF-525 can capture CO2 and convert it into useful chemicals

by
SciTechDaily

By means of Jennifer McManamay, University of Virginia School of Engineering and Applied Science June 2, 2024 Researchers have made significant progress in the practical application of a new material known as MOF-525, a member of the metal-organic framework family, which shows great promise in carbon capture and conversion technologies. The team has developed a … Read more

Once-in-2,000-year event: Study explains unprecedented ice loss in Antarctica, equivalent to 10x the size of Britain

by
SciTechDaily

In 2023, Antarctic sea ice fell to historically low levels, prompting researchers to use CMIP6 climate models to assess the rarity of the event and its link to climate change. The study found that without climate change such a drastic reduction would be extremely rare, but current climate conditions made it more likely. The research … Read more

The largest ice shelf in Antarctica is behaving strangely

by
SciTechDaily

By means of Washington University in St. Louis May 25, 2024 Research from Washington University in St. Louis shows that the Ross Ice Shelf in Antarctica, about the size of France, is disrupted daily by an ice flow. This movement, caused by a sudden slip in the ice flow, could affect icequakes and ice shelf … Read more

Doomsday Glacier’s ticking clock: Satellites reveal “powerful melt” beneath Antarctica’s Thwaites Glacier

by
SciTechDaily

A team led by glaciologists from UC Irvine used satellite radar data to reconstruct the impact of warm ocean water rising in a grounding zone extending several kilometers beneath the Thwaites Glacier in West Antarctica. The research, the subject of an article published in PNAS, will help climate modelers derive more accurate projections of sea … Read more
