A few years ago, Rensselaer Polytechnic Institute’s Sasha Wagner, assistant professor of earth and environmental sciences, proved false what scientists had thought for years. Soot-like molecules that formed an ancient carbon pool deep in the Pacific Ocean did not, in fact, originate from wildfires on land.“We discovered that there was an isotopic mismatch,” Wagner said.

A new study of zircon crystals from two of Earth’s oldest continents indicates that the formation of Earth’s continental crust goes through cycles, with periods of increased crust production roughly every 200 million years, corresponding to the solar system’s transit through the four primary spiral arms of the Milky Way galaxy.
New Curtin research has found evidence that Earth’s early continents resulted from being hit by comets as our Solar System passed into and out of the spiral arms of the Milky Way Galaxy, turning traditional thinking about our planet’s formation on its head.
A new research center is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J.

A new study measured 38 years of change for glaciers in Kenai Fjords National Park, which lies south of Anchorage, and found that 13 of 19 glaciers show substantial retreat, four are relatively stable, and two have advanced. It also finds trends in which glacier types are disappearing fastest.
Researchers at the University of Bristol and Scottish Universities Environmental Research Centre have discovered that super-eruptions occur when huge accumulations of magma deep in the Earth’s crust, formed over millions of years, move rapidly to the surface disrupting pre-existing rock.
California’s McKinney Fire grew to become the state’s largest fire so far this year. The risk of wildfire is rising globally due to climate change. Below are some of the latest articles that have been added to the Wildfires channel on Newswise.

In the deep subsurface that plunges into the Earth for miles, microscopic organisms inhabit vast bedrock pores and veins.
More of the world’s coastal glaciers are melting faster than ever, but exactly what’s triggering the large-scale retreat has been difficult to pin down because of natural fluctuations in the glaciers’ surroundings. Now, researchers have developed a methodology that they think cracks the code to why coastal glaciers are retreating, and in turn, how much can be attributed to human-caused climate change.
The latest technology to study glaciers fits in a backpack and can be carried up steep mountains. University of Oregon researchers have developed a portable tool that uses lasers to measure the composition of glacial ice, data that can help determine how fast that ice is melting. The instrument can be used to study glaciers in remote wilderness areas, like those in Oregon’s Cascade Mountains. And it can help verify satellite data collected about bigger glaciers, like those in Greenland and Antarctica.
For the first time, scientists have shown that glaciers in the tropical Andes mountains have been in sync with polar ice extent in Antarctica and the Arctic for nearly a million years. A study, published July 13 in Nature, is the first to show that the effects of greenhouse gases and other drivers of the Earth’s temperature are impacting glaciers in the Southern Hemisphere at the same pacing as ice sheets in the north.
Astronomy postdoc Valerie Payré is on an international team that discovered the origin of the martian meteorite known as Black Beauty, one of the most-studied meteorites in the world.

By analyzing noble gas isotope data, a scientist determined that the ancient plume mantle had a water concentration that was a factor of 4 to 250 times lower when compared with the water concentration of the upper mantle. The resulting viscosity contrast could have prevented mixing within the mantle, helping to explain certain long-standing mysteries about Earth’s formation and evolution.
