Scientists have developed a new technique using ice-penetrating radar to study long-ago changes in West Antarctic ice streams. This allows them to look at changes much farther back in time, indicating possible fluctuations in the stability of the massive West Antarctic Ice Sheet.
A new study suggests the West Antarctic Ice Sheet's complete disintegration in 7,000 years could be inevitable due to its potential instability. The ice sheet's collapse would raise global sea levels, flooding low-lying coastal regions and posing a significant threat to global climate patterns.
A new study reveals that global surface temperatures have increased by 14.6 degrees Celsius, with the warmest years on record occurring in the 1990s. Most of the warming has occurred over the northern continents during specific seasons.
Scientists Dr. Jeffrey R. Johnson and colleagues developed a helium-3 map of the Moon based on factors like exposure age, solar wind, and titanium content. The greatest amounts of helium-3 are expected to be found on the far side maria and in nearside areas with high concentrations of titanium dioxide.
Dinosaur tooth enamel holds secrets to ancient climate conditions, with new analysis suggesting middle latitudes may not have been warmer than today. Data from Madagascar indicates sub-tropical latitudes were warmer and more arid during the Late Cretaceous era.
Researchers have assembled 20 articles to study interactions at the Antarctic Continental Margin, presenting new techniques and expanding year-round measurements. The volume includes a bathymetric chart of the southern Weddell Sea, providing insights into longer-term cycles.
Scientists have identified several elements in the lunar atmosphere, including oxygen, silicon, and aluminum, but only in small amounts. The study aims to learn which other atoms the regolith may release and form part of the Moon's atmosphere.
Researchers have demonstrated an instance of a thin ion layer being pushed downward to create a neutral sodium layer. Contrary to predictions, the formation of this layer was not significantly affected by intense auroral ionization, revealing new insights into the physics and chemistry of the upper atmosphere.
The University of Illinois has created a 2,500 square meter prehistoric domestic compound to teach students how to conduct non-invasive archeogeophysical testing. The site, called CATS, features various archaeological features typical of Eastern and Midwestern Native American cultures of 600 to 2,000 years ago.
