How did rocks rust on Earth and turn red? A Rutgers-led study has shed new light on the important phenomenon and will help address questions about the Late Triassic climate more than 200 million years ago, when greenhouse gas levels were high enough to be a model for what our planet may be like in the future.

Every late winter and early spring, huge dust storms swirled across the bare and frozen landscapes of Europe during the coldest periods of the latest ice age.
Antarctic ice is melting, contributing massive amounts of water to the world’s seas and causing them to rise – but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years’ worth of satellite data indicates.

There isn't much in Kamchatka, a remote peninsula in northeastern Russia just across the Bering Sea from Alaska, besides an impressive population of brown bears and the most explosive volcano in the world. Kamchatka's Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years.
Microscopic bubbles can tell stories about Earth's biggest volcanic eruptions and geoscientists from Rice University and the University of Texas at Austin have discovered some of those stories are written in nanoparticles.
Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to Rutgers scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to a Rutgers-led study – the first of its kind – in the journal Geophysical Research Letters. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.
CSU geology experts study the active land California inhabits to better understand earthquakes and predict the location and intensity of future temblors.

Writing in PNAS, scientists from Cologne university present important new constraints showing that plate tectonics started relatively slow, although the early Earth's interior was much hotter than today.
The Earth’s soils contain more than three times the amount of carbon than is found in the atmosphere, but the processes that bind carbon in the soil are still not well understood.
With no dissolved oxygen to sustain animals or plants, ocean anoxic zones are areas where only microbes suited to the environment can live.
A new study led by researchers in the Geography Department at Swansea University reveals the extreme scale of loss and fragmentation of tropical forests, which once covered much of the Indonesian islands of Sumatra and Kalimantan.
Ancient Punt was a major trading partner of Egyptians for at least 1,100 years. It was an important source of luxury goods, including incense, gold, leopard skins, and living baboons.
A study by the University of Southampton gives a new perspective on why our planet has managed to stay habitable for billions of years - concluding it is almost certainly due, at least in part, to luck.
Despite its tropical-sounding name and exotic-tasting In a recent article in Plant Ecology, Associate Professor The pawpaw is extremely rare in New York State, with only 20 known locations. Stephen Tulowiecki, a geographer at SUNY Geneseo, studied the conditions that pawpaws favor, and developed a model to predict locations where pawpaws may grow and identify areas that might sustain newly introduced trees.
The Last interglacial period was the last warm period before our present Holocene age and dates back some 129,000 to 116,000 years ago.
At a North Carolina beach, researchers have been poking and prodding the sand to study how moisture levels affect sounds as they move across the environment. Over short distances, even moderately wet sand reflects sound more like water does than as a solid surface does. Faith Cobb and her team are looking into if the same is true for long-range sound propagation. Their findings will be presented as a part of the 179th ASA Meeting.
Using a trained neural network and data from the North Anatolian Fault in Turkey, a research team led by Los Alamos National Laboratory revealed the first direct observation of rupture propagation during a slow earthquake.
While offshore wind projects provide clean and renewable energy, a new study from the University of Delaware shows that they can also have unintended effects on local weather in the form of minimal, though statistically significant, impacts when it comes to wind speed and reduced precipitation at nearby onshore locations.
A small group of volcanic islands in Alaska's Aleutian chain might be part of a single, undiscovered giant volcano, say scientists presenting the findings Monday, 7 December at AGU's Fall Meeting 2020.

In a study published this week in The Cryosphere, researchers from the National Centre for Atmospheric Science and University of Reading demonstrate how climate change could lead to irreversible sea level rise as temperatures continue to rise and the Greenland ice sheet continues to decline.
The number of wildfires and the amount of land they consume in the western U.S. has substantially increased since the 1980s, a trend often attributed to ongoing climate change.
Methane, the main component of natural gas, is the cleanest-burning of all the fossil fuels, but when emitted into the atmosphere it is a much more potent greenhouse gas than carbon dioxide.
