Does Planting Trees Really Help Cool the Planet?

Restoring forests—particularly in tropical regions—may have a stronger cooling effect than previously thought. However, even if all the trees lost since the mid-1800s were replanted, it wouldn’t be enough to fully offset the warming caused by human activities. Reducing greenhouse gas emissions is still crucial. A new modeling study from the University of California, Riverside—published […]

UN Warns: High Odds We’ll Surpass 1.5°C Temperature Increase by 2029

The United Nations announced on Wednesday that there is a 70% likelihood that the average global temperature from 2025 to 2029 will exceed the critical threshold of 1.5 degrees Celsius. Following the two hottest years ever recorded in 2023 and 2024, the planet is expected to continue experiencing unprecedented warming levels, as detailed in the

Trees May Be Able to Warn Us When a Volcano Is About to Erupt

Earth Science, Science, Volcanology / Samilton Santos

Predicting volcanic eruptions is a crucial science that can save many lives, and recent research suggests that the color of tree leaves near volcanoes might serve as an early warning sign before an eruption occurs. Magma, Carbon Dioxide, and Greener Leaves As volcanic activity intensifies and magma rises closer to the Earth’s surface, the amount

Microplastics Could Be Allies in Monitoring Sewage in Rivers

Environmental Science, Science / Samilton Santos

Although people often associate microplastics with environmental hazards, researchers now propose that these particles can actually serve a useful role by helping detect sewage contamination in waterways. Turning a Weakness into a Strength One of the main concerns about microplastic pollution is their tendency to attract and carry harmful bacteria.However, researchers could harness this same

Watch: Lava Jets Shoot 1,000 Feet from Hawaii’s Kīlauea Volcano

Earth Science, Science, Volcanology / Samilton Santos

Kīlauea, known as one of the world’s most active volcanoes, has erupted once again. Massive Lava Jet Reaches 1,000 Feet Since the end of last year, its crater has been intermittently shooting lava fountains, and on May 25, a jet of molten rock soared an impressive 300 meters (1,000 feet) into the air. The United

Earth’s Core Contains a Vast Reservoir of Gold — And It’s Leaking Toward the Surface

Earth Science, Environmental Science / Samilton Santos

Earth’s core holds an enormous amount of gold, and this precious metal is slowly making its way into the planet’s crust, according to a new study. Volcanic Rocks Reveal Traces of Precious Metals Researchers analyzed isotopes found in volcanic rocks that emerged from deep beneath the lithosphere and identified traces of precious metals — including

Larvae-Attracting Gel Could Help Restore Destroyed Coral Reefs

Environmental Science, Science / Samilton Santos

We can’t leave coral reef restoration to chance. To help coral larvae settle in damaged reef areas, researchers developed an algae-based gel that actively attracts them. The Hidden Builders of Coral Reefs Although many people assume coral polyps produce all the calcium carbonate in reef structures, crustose coralline algae actually produce a significant portion of

New AI Weather Model Surpasses Leading Global Forecasting Systems

Climatology, Earth Science, Environmental Science / Jorge Paka

Microsoft has created an artificial intelligence (AI) model that outperforms traditional forecasting techniques in tracking air quality, weather systems, and climate-driven tropical storms, according to a study published Wednesday. Named Aurora, the system—still not commercially available—produced 10-day forecasts and predicted hurricane paths with greater accuracy, speed, and lower cost than standard models, researchers noted in

InventWood is on the Verge of Mass-Producing Wood Stronger than Steel

Climatology, Earth Science / Leandro Conceição

It may sound like science fiction, but it originates from a lab in Maryland. In 2018, Liangbing Hu, a materials scientist at the University of Maryland, developed a method to transform regular wood into a material stronger than steel. At first, it appeared to be another eye-catching discovery that might never leave the lab. “People

Modular Carbon Capture Technology Reduces Cargo Ship CO₂ Emissions by 70%

Environmental Science, Science / Samilton Santos

The oceans may be getting a little cleaner with the commercial launch of the Carbon Capture Solution (CCS) system, developed by technology company Wärtsilä. This modular system claims to capture up to 70% of the carbon dioxide emitted from cargo ship exhausts. Growing Pressure to Cut Emissions Driven by environmental concerns or the need to
