Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]

The amount of CO2 is increasing all the time – we just passed a landmark 400 parts per million concentration of atmospheric CO2, up from around 280ppm before the industrial revolution. That’s a 42.8% increase. A tiny amount of CO2 and other greenhouse gases, like methane and water vapor, keep the Earth’s surface 30°Celsius (54°F) warmer than it would be […]

In 2015, scientists predicted that a massive solar eruption would hit Earth just before New Year’s Eve. It was expected to cause power fluctuations, radio blackouts and even affect GPS reception. There was a small chance it could make the Northern Lights visible in the San Francisco Bay Area. The National Oceanic and Atmospheric Administration predicted that the Aurora Borealis […]

Mystery crater: A 40-foot crater has appeared in the ground near Managua airport. Nicaraguan authorities said the hole was caused by a meteorite that broke off from the passing Pitbull, or 2014 RC, asteroid. But NASA officials said that was unlikely, because such a strike would have produced an enormous fireball streaking across the sky, yet nobody reported seeing anything […]

Long ago, in the largest canyon system in our solar system, vibrations from “marsquakes” shook soft sediments that had accumulated in Martian lakes. The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on NASA images. The map was released today by the U.S. Geological Survey (USGS). This map of […]

A research paper published in Nature Climate Change predicts widespread death of needleleaf evergreen trees (NET) within the Southwest United States by the year 2100 under projected global warming scenarios. The research team that conducted the study, which includes University of Delaware’s Sara Rauscher, considered both field results and a range of validated regional predictions and global simulation models of […]

The National Geographic Society has joined scientists from around the world in adding a fifth named ocean to the world map even though the idea is still not accepted by all countries. For World Oceans Day on Tuesday, the society announced it is recognizing the Southern Ocean, which circles Antarctica up to a latitude of 60 degrees South. It joins […]

What is hail or a hailstone? Hail is a form of precipitation that occurs when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere where they freeze into balls of ice. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. How does hail form? Hailstones grow by colliding with supercooled […]
