Air Pollution Cuts in East Asia May Have Sped Up Global Warming

Climatology, Earth Science, Environmental Science / Jorge Paka

A new study published Monday (July 14) in Communications Earth and Environment reveals that efforts to reduce air pollution in East Asia have contributed to a faster pace of global warming. Global warming—primarily driven by greenhouse gas emissions—has been accelerating over the past 15 years, causing record-high surface temperatures. During this same period, East Asian […]

Researchers Flag 4,200 Harmful Plastic Chemicals, Urge Safer Alternatives

Earth Science, Environmental Science / Jorge Paka

Nations are in the process of negotiating a global agreement aimed at ending plastic pollution and improving the safety and sustainability of plastics. A key concern in these talks is the presence of chemicals in plastics—ranging from food wrappers to car tires—that can seep into food, household environments, and ecosystems. Many of these plastic-related chemicals

Climate Change’s Earliest Detectable Sign Emerged 130 Years Ago

Climatology, Earth Science, Environmental Science / Jorge Paka

Had 19th-century scientists possessed today’s advanced atmospheric tools, they might have detected the earliest signs of climate change caused by human activity—specifically, the burning of coal and wood. Scientists Suggest Climate Change Could Have Been Detected as Early as 1885 In a recent thought experiment, a group of Earth and atmospheric scientists concluded that, with

Finland Powers Up World’s Largest Sand Battery with Promising Economics

Climatology, Earth Science / Jorge Paka

It may not look like much, but Finland has just powered up the world’s largest sand battery—a massive 49-foot silo filled with 2,000 metric tons of crushed rock. Yes, actual sand. This type of thermal energy storage system works by using electricity—often from renewable sources—to heat sand or crushed rock. The stored heat can then

The Atmosphere’s Growing Thirst: A Key but Overlooked Factor in Intensifying Droughts

Earth Science, Environmental Science, Science / Samilton Santos

Droughts are becoming increasingly intense and widespread around the world—but declining rainfall isn’t the only reason. A lesser-known culprit is the atmosphere’s growing demand for water. In a recent Nature study, my colleagues and I found that this increased “atmospheric thirst”—technically known as atmospheric evaporative demand (AED)—has driven around 40% of the worsening drought conditions

A Huge Saharan Dust Plume Is Headed Toward the United States

Climatology, Earth Science, Environmental Science / Jorge Paka

Dust from the Sahara Desert is set to drift over the southeastern United States this week, part of an annual weather phenomenon that doesn’t always make it as far as North America. Saharan Air Layer Sends Thick Dust Plumes Across Atlantic Each Summer, Driven by Tropical Winds and Moist Ocean Air The dust originates from

Scientists Create ‘Living Concrete’ That Repairs Its Own Cracks

Earth Science, Science / Samilton Santos

Concrete remains a widely used and highly adaptable construction material, but it has notable drawbacks—particularly its tendency to crack due to low tensile strength. To address this vulnerability, researchers have been exploring ways to develop concrete that can repair itself, and a new innovation might be a significant breakthrough. A Self-Healing Breakthrough Using Synthetic Lichen

Scientists Reveal: South Africa Is Emerging From The Ocean

Earth Science, Environmental Science, Science / Ana Manuel

As climate change accelerates, South Africa is not only experiencing increased heat and dryness—it’s also gradually rising by as much as 2 millimeters per year, according to new research. While scientists already recognized this upward movement, they previously attributed it to mantle flow beneath the Earth’s crust in the region. However, the new study links

Your Salad Might Be Bringing Microplastics From Soil Into Your Body

Earth Science, Environmental Science, Science / Samilton Santos

Tiny plastic particles are infiltrating agricultural soils, bringing with them hazardous chemical additives and pollutants. These substances have already been found in foods like lettuce, wheat, and carrots, showing how plastics and their compounds can enter the food chain — ending up in your salad and, eventually, inside your body. Tracking the Sources of Contamination
