New research reveals the missing piece: spring rain, or rather, the lack of it. Warmer, drier springs mean plants are soaking up more snowmelt before it can reach rivers, fueled by sunny skies that boost growth and evaporation. In fact, this shift explains nearly 70% of the shortfall, tying the mystery directly to the long-running Millennium drought.

Scientists discovered that most microplastics arrive through the air, settling onto treetops before being washed or dropped to the forest floor in rain and falling leaves. Once there, natural processes like leaf decay help bury and store these particles deep in the soil. The findings reveal forests as hidden reservoirs of airborne pollution—and potentially a new frontline in the growing microplastics crisis.

Scientists studying Africa’s largest blackwater lakes discovered that significant amounts of carbon dioxide bubbling into the atmosphere come not just from recent plant life, but from peat that has been locked away for thousands of years. Tue, 24 Feb 2026 08:16:20 EST https://www.sciencedaily.com/releases/2026/02/260224023201.htm https://www.sciencedaily.com/releases/2026/02/260221000325.htm Deep in the Arctic north, drained peatlands—once massive carbon vaults built over thousands of years—are quietly leaking greenhouse gases into the atmosphere. But new field research from northern Norway suggests there’s a powerful way to slow that loss: raise the water level. In a two-year study, scientists found that restoring higher groundwater levels in cultivated Arctic peatlands dramatically cut carbon dioxide emissions, and in some cases even tipped the balance so the land absorbed more CO₂ than it released.

Its surface isn’t uniform — it’s a nanoscale patchwork of positive and negative charges that can grab many different organic molecules. Instead of relying on a single weak attraction, the mineral uses several bonding strategies to hold carbon tightly in place. This helps explain how soils store enormous amounts of carbon for the long term.

Cracks in sea ice release heat and pollutants that form clouds and speed up melting, while emissions from nearby oil fields alter the chemistry of the air. These interactions trigger feedback loops that let in more sunlight, generate smog, and push warming even further. Together, they paint a troubling picture of how fragile the Arctic system has become.

As the planet warms, nutrient-rich runoff fuels plankton blooms that bury huge amounts of carbon in the ocean. In low-oxygen conditions, this process can spiral out of control, cooling Earth far beyond its original state. While this won’t save us from modern climate change, it may explain Earth’s most extreme ancient ice ages.

This frozen archive, meticulously analyzed by scientists, captures a complete chemical and atmospheric record spanning humanity’s transition from hunter-gatherers to modern industry. The core contains stories of erupting volcanoes, changing forests, Saharan dust storms, and even economic impacts across history. It offers a rare glimpse into both natural climate transitions and human influence on the atmosphere, holding vital clues for understanding past and future climate change.

High above the Arctic, two distinct polar vortex patterns — both distorted and displaced — play a major role in steering icy air toward different regions. One sends it plunging into the Northwest, while the other aims it at the Central and Eastern U.S. Since 2015, the westward version has been more common, bringing intensified cold to the Northwest in defiance of global warming trends. This stratospheric detective work offers fresh insight into extreme winter weather — and could supercharge long-range forecasts.

By using a compound normally found in pool disinfectants and a novel polymer that can be reused, the method avoids toxic chemicals like mercury and cyanide. It even works on trace gold in scientific waste. Tested on everything from circuit boards to mixed-metal ores, the approach offers a promising solution to both the global gold rush and the growing e-waste crisis. The technique could be a game-changer for artisanal miners and recyclers, helping recover valuable metals while protecting people and the planet.
