Poyang Lake Shrinks 90%: China’s Largest Freshwater Lake Meets Extreme Low Water
Overview: A Shrinking Giant China’s largest freshwater lake, Poyang Lake in Jiangxi province, has entered an extremely low-water phase after tumbling to a level that is 90 percent below its typical high-water season peak. Local authorities reported the dramatic drop, underscoring ongoing concerns about regional hydrology, weather patterns, and the balance between water supply, ecology,…

Poyang Lake Shrinks 90%: China’s Largest Freshwater Lake Faces Severe Low Water
Overview: A Lake in the Grip of an Extreme Drought China’s largest freshwater lake, Poyang Lake in Jiangxi province, has fallen to an extremely low-water level, shrinking by about 90 percent from its peak during the high-water season. Local authorities reported the dramatic decline at the Xingzi hydrological station, signaling a hydrological event with potential…

From Mantle Flow to River Flow: Shaping Earth’s Surface from Within
From Mantle Flow to River Flow: A Window into Earth’s Hidden Forces Editors’ Highlights from Geophysical Research Letters pull back the curtain on how Earth’s deep interior steadily sculpts the world we walk on. A new global analysis synthesizes data on mantle dynamics and surface features, revealing a coherent story: the slow, convecting mantle sets…

From Mantle Flow to River Flow: How Earth’s Interior Shapes Surface Features
Introduction: Reading the Earth’s Hidden Currents The Earth’s surface bears the fingerprints of processes operating far below our feet. A new global synthesis, inspired by recent work featured in Geophysical Research Letters, connects the deep dynamics of mantle flow with the visible architecture of faults, fractures, and river systems. By tracing how the slow, buoyant…

Peatlands at Risk: The World’s Largest Carbon Reservoir Faces Release Threats
Overview: Peatlands as a Global Carbon Reservoir Peatlands cover a small portion of the Earth’s surface but store a disproportionate share of the planet’s soil carbon. Recent reporting from Caitlin Hayes, shared with the Cornell Chronicle newsroom, highlights how this vast reservoir—estimates place it at several hundred gigatons of carbon—faces increasing risk as climate change…

Peatlands at Risk: Protecting a Huge Carbon Reservoir from Release
Peatlands: Nature’s Massive Carbon Reservoir Peatlands, a unique class of wetlands that accumulate partially decayed vegetation, hold a staggering amount of Earth’s carbon. Though they cover only about 3% of global land area, these ecosystems store an estimated 30% of soil carbon, far more than forests in many regions. Recent research underscores that the stability…
