How widespread will the effects be as polar ice caps melt in a warming climate and release fresh water into our oceans? An international research group led by Missouri S&T researchers may have found some answers after investigating a lake on the Caribbean coast of Guatemala.Around 8,200 years ago, an ice dam collapsed and released water from two large lakes located near the current border between the United States and Canada.
The earliest solids formed in the solar system give clues to what radioactive species were made by the young sun, and which ones were inherited. By studying isotopic variations of the elements vanadium (V) and strontium (Sr), an international team of researchers including scientists from Lawrence Livermore National Laboratory found that those variations are not caused by irradiation from the sun but are produced by condensation and evaporation reactions in the early solar system.

Soil on Mars is different than soil on Earth, and exploration is helping us learn more
Vesta was hit by two other large asteroids which left large impact craters so big they cover most of the southern hemisphere of Vesta. These impacts are thought to have ejected rocky material into space. Some of these rocks reached Earth as meteorites so scientists now have actual rock samples from Vesta to study its geochemistry.
Cornell professor and collaborators collect data that could provide new insight into the mechanics of crustal faults and possibly help researchers understand and anticipate future earthquake clusters.
A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth’s early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes.
Ocean deoxygenation during the Mesozoic Era was much more rapid than previous thought, with CO2 induced environmental warming creating ocean ‘dead zones’ over timescales of only tens of thousands of years.
The Antarctic Ice Sheet, Earth’s southern polar ice sheet, has grown and receded and grown again over millions of years.
Scientists at the University of Southampton have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide (CO2) over geological time.
The findings of a new study by the University of Liverpool provides further evidence of an approximately 200-million-year long cycle in the strength of the Earth’s magnetic field.
Expert Q&A: Do breakthrough cases mean we will soon need COVID boosters? The extremely contagious Delta variant continues to spread, prompting mask mandates, proof of vaccination, and other measures. Media invited to ask the experts about these and related topics.
New research from Florida State University and Rice University is providing a better estimate of the amount of carbon in the Earth’s outer core, and the work suggests the core could be the planet’s largest reservoir of that element.
A new study predicts that any sea level rise in the world’s most southern continent will be countered by an increase in snowfall, associated with a warmer Polar atmosphere. Using modern methods to calculate projected changes to sea levels, researchers discovered that the two ice sheets of Greenland and Antarctica respond differently, reflecting their very distinct local climates.
Ice losses from Thwaites Glacier in West Antarctica are currently responsible for roughly four percent of the global sea-level rise.
