Mars’ Ancient Lakes Hid Under Ice to Stay Warm Longer
Introduction: A New Look at Martian Water For decades, scientists have puzzled over how water persisted on the surface of ancient Mars as the climate grew progressively harsher. A compelling new interpretation suggests that thin lids of ice could have formed above ancient lakes, insulating surface water and keeping it liquid long after the planet…

Earth’s Ancient Climate Hints at Unstable Rainfall Ahead
Introduction: Why the Paleogene Matters for Today Understanding Earth’s past helps scientists forecast how a warming planet may reshape rainfall patterns. A pivotal chapter lies in the Paleogene Period, starting about 66 million years ago, when the world’s climate shifted dramatically. By studying this era—when continents rearranged, ice sheets fluctuated, and atmospheric carbon dioxide levels…

Paleogene Climate: Rainfall Instability Clues for Today
Introduction: Why the Paleogene Matters for Modern Rainfall When scientists look back to Earth’s deep past, they search for patterns that might hint at the future. The Paleogene Period, starting about 66 million years ago, is a focal point for understanding how a warming world alters the hydrological cycle. During this era, our planet experienced…

What Paleogene Rainfall Teaches Us About Today’s Warming World
Understanding the Paleogene: A Window into a Warmer Earth Scientists study Earth’s deep past to forecast how current warming might reshape rainfall and floods. The Paleogene Period, spanning roughly 66 to 23 million years ago, marks a time when the planet was notably warmer than today. This era offers crucial clues about how atmospheric composition,…

What Past Global Warming Reveals About Future Rainfall
Understanding the link between past warming and future rainfall To forecast how climate change will reshape rainfall, scientists often look to the distant past. The Paleogene Period, which began about 66 million years ago, offers a natural laboratory where atmospheric carbon dioxide levels were two to four times higher than today. By studying ancient climates,…

Antarctica’s 9,000-Year Ice Collapse: Lessons for Today’s Ocean-Driven Melt
New insights into an ancient trigger: warmer oceans and rapid ice loss Scientists have pieced together evidence that about 9,000 years ago, a portion of East Antarctica’s ice sheet collapsed unusually quickly. The event, driven by warmer ocean waters intruding under the ice, offers a window into how today’s oceans might influence the stability of…

9,000-Year-Old Melt Reveals How Fast Antarctica Can Fall Apart
New insights from ancient ice reveal a fragile Antarctic system Researchers have traced a dramatic pattern in Antarctica’s ice history: melt events from thousands of years ago show how regional melting can quickly propagate across the continent through oceanic connections. The study, which examines geologic and climatic records from ancient ice, indicates that ice retreat…

Could a Hidden Earth Thermostat Warp Our Climate Fate and Trigger the Next Ice Age on Time
Introduction: A New Twist in Earth’s Climate Regulation Scientists have long studied how Earth maintains climate balance over geological timescales. A recently highlighted finding suggests there isn’t just one thermostat at work—there could be a hidden, supercharged mechanism that accelerates the burial of carbon beneath the seafloor. If true, this could cause the next ice…
