Seismic Activity Under Alaskan Volcano May Indicate Imminent Eruption

Earth Science, Volcanology /

Small earthquakes beneath Alaska’s Mount Spurr suggest that the volcano may be nearing an eruption. Located about 3,370 meters (11,070 feet) above sea level, the mountain has experienced a surge in seismic activity recently, with thousands of minor earthquakes reported. Increased Chances of Eruption Matthew Haney, a volcano seismologist at the Alaska Volcano Observatory, informed […]

Recycled Wind Turbine Blades Turned into Asphalt for New Roads

Earth Science, Environmental Science /

Wind turbines provide an excellent source of clean energy, but disposing of them when they are decommissioned presents a major challenge. Researchers in China have discovered a practical method to recycle discarded turbine blades, using them to create durable roads. This technique could be particularly useful as the number of wind turbines grows and more

Scented Products Cause indoor Air Pollution on Par With Car Exhaust

Earth Science, Environmental Science /

Using scented products indoors alters the air chemistry, generating as much pollution as car exhaust does outside, according to a new study. Researchers warn that breathing in these tiny particles could have serious health consequences. Indoor Air Pollution from Common Household Items When you hear or think about “air pollution,” you likely associate it with

Yellowstone’s Hot Springs May Reveal Clues About Earth’s Early Oxygen Use

Earth Science, Environmental Science /

Recent research from Montana State University suggests that microbial life in Yellowstone’s Lower Geyser Basin could provide insight into the evolution of how life adapted to use oxygen. The microorganisms living in the Octopus and Conch Springs thrive in kelp-like, gelatinous structures known as “streamers,” which move rapidly in the superheated waters around 88°C (190°F).

Bacteria Feed on Toxic and Persistent PFAS Chemicals

Environmental Science /

The so-called “forever chemicals” (PFAS) are increasingly present in the environment, food, drinking water, and even our bodies. However, researchers may have found a new solution to this problem: a bacterium capable of consuming these compounds and their toxic byproducts. Per- and polyfluoroalkyl substances (PFAS) have been widely used for decades due to their water-repellent

Enigmatic Blue Tree Rings Uncover History’s Harshest Summers

Environmental Science /

A simple blue stain may unlock trees’ memories of cold summers and volcanic winters, offering scientists a precise new tool to reconstruct ancient climates through timber anatomy. By combining the biological stains safranin and astra blue, researchers can highlight areas with low lignin, a compound that strengthens plant cell walls. When trees and shrubs experience

“Shocking”: Record-Breaking January Heat Leaves Scientists Stunned

Earth Science /

January set a new heat record, defying expectations that La Niña would bring cooling. Copernicus Climate Change Service reported temperatures 1.75°C above pre-industrial levels, extending a historic warming trend. Scientists expected a cooldown after El Niño peaked in early 2024, but extreme heat persists, fueling debate over additional warming factors. Every fraction of a degree

Claim That ‘2-Degree Target Is Dead’ Sparks Debate on Climate Scenarios

Environmental Science /

Keeping global warming under 2°C—the fallback goal of the Paris Agreement—is now “impossible,” according to a controversial new study by prominent climatologist James Hansen and his team. Published in Environment: Science and Policy for Sustainable Development, the paper argues that Earth’s climate is more sensitive to greenhouse gas emissions than previously thought. Adding to the

The Ocean’s Surface Is Heating Up Over Four Times Faster Than in the 1980s

Environmental Science /

The sharp rise in global temperatures since 2023 has fueled relentless disasters worldwide, from the still-burning LA fires to the deadly Valencia floods, leaving scientists scrambling for answers. New ocean data suggests a key culprit: an alarming acceleration in sea surface warming. A study from the University of Reading reveals that the ocean’s surface is

New Study Reveals “Remarkable” Glacier Loss in Climate Change Hotspot

Earth Science /

A recent University of Bristol study, published in Nature Communications, reveals the rapid shrinkage of glaciers in Svalbard, Norway, over the past 40 years. The study shows that 91% of glaciers have significantly retreated, losing over 800 square kilometers of ice since 1985. Moreover, 62% now experience seasonal calving cycles due to rising temperatures in
