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

AI Analyzed Millions of Arctic Images and Discovered a Concerning Trend

Climatology, Earth Science, Environmental Science /

Since 1979, the Arctic has warmed almost four times faster than the global average. Svalbard, an archipelago off Greenland’s northeast coast, is experiencing climate change at an even faster rate, warming up to seven times quicker than the rest of the planet. More than half of Svalbard is covered by glaciers, and if they were

Mystery of the Summer-Killing Volcano Uncovered

Earth Science, Volcanology /

A longstanding mystery about a year that effectively skipped summer appears to have been resolved. Researchers, using advanced ice core analysis, have determined that the dramatic cooling of 1831 resulted from a massive volcanic eruption in a remote region north of Japan. 1831: A Year of Global Climate Turmoil In 1831, the global climate took

Ocean Current Defies Doomsday Predictions, Stays Steady for 60 Years

Earth Science /

Earth’s oceans, covering 71% of the planet’s surface, profoundly shape global climate and weather. At the heart of this system is the Atlantic Meridional Overturning Circulation (AMOC), a network of Atlantic currents driven by wind and ocean density differences. The AMOC redistributes heat, moisture, and nutrients worldwide, playing a critical role in regulating Earth’s climate.

Using Seawater to Combat LA Fires is an Experiment Scientists are Monitoring Closely

Climatology, Earth Science, Environmental Science /

Firefighters tackling the devastating wildfires that swept through the Los Angeles area in January 2025 faced challenges due to limited freshwater supplies. When conditions allow, experienced pilots operating aircraft known as Super Scoopers collect 1,500 gallons of seawater at a time, delivering it with pinpoint accuracy to combat the flames.
