Walk-through: AMNH’s Impact exhibit on the asteroid that doomed the dinosaurs
Overview: A multidisciplinary journey into the dinosaur extinction In New York City, the American Museum of Natural History opens a bold new exhibition that looks at the asteroid strike credited with ending the reign of the non-avian dinosaurs. The Impact exhibit invites visitors to move beyond a single narrative, weaving together geology, paleontology, archaeology, climate…

The Invisible Brake: Near-Surface Cooling Stalls Giant Dyke Swarms
Introduction: Unveiling the Hidden Controls on Giant Dyke Swarms Giant dyke swarms are among Earth’s most striking geological features: networks of long, sheet-like cracks that channel molten rock laterally through the crust. These structures play a pivotal role in how magma intrudes, migrates, and eventually erupts. Recent insights, distilled from the Journal of Geophysical Research:…

The Invisible Brake: How Near-Surface Cooling Stalls Giant Dyke Swarms
The Hidden Brake on Magma: Near-Surface Cooling and Dyke Swarms Giant dyke swarms are among Earth’s most striking subterranean features: networks of long, sheet-like cracks that channel magma sideways through the crust, helping shape volcanic landscapes and crustal evolution. A recent synthesis from the Journal of Geophysical Research: Solid Earth highlights a surprising factor in…

Volcanic Rocks Could Store CO2 Safely, Study Finds
New evidence that ancient volcanic rocks can store CO2 Researchers from the University of Edinburgh have identified several underground volcanic rock formations around the United Kingdom that could transform carbon capture and storage (CCS). The key finding is carbon mineralization: CO2 reacting with minerals in these rocks to form stable carbonates, effectively turning a greenhouse…

Could Climate Change Drive Earth Toward a New Ice Age?
Introduction: A provocative idea with historical context Climate historians know Earth has endured dramatic swings long before humans learned to emit greenhouse gases. The planet’s long arc has included warm intervals and icy chapters, driven by a mix of natural cycles and geological processes. Some researchers now ask a surprising question: could the combination of…

Climate Change Could Heat the Earth Into a New Ice Age: What Science Suggests
Understanding the Debate: Can Warming Trigger a New Ice Age? Climate change is widely associated with rising temperatures, melting ice, and extreme weather. Yet some scientists have explored a provocative question: could enough warming alter global climate dynamics so dramatically that a cooling feedback eventually ushers in a new ice age? While this scenario may…

Crumbled Cradle: How a Splitting Supercontinent Might Have Sparked Life on Earth
New Clues from a Fractured Era Scientists are revisiting a dramatic chapter in Earth’s deep past—the break-up of a once-mighty supercontinent and how its disintegration could have set the stage for life as we know it. By linking plate tectonics to climate shifts and ocean chemistry, researchers are exploring how a crumbling landmass might have…

Could a Crumbling Supercontinent Have Jumpstarted Life on Earth?
New Clues That Earth’s Crumbling Supercontinent Could Have Sparked Life When scientists talk about Earth’s distant past, they often reference dramatic shifts in geography and climate. A growing body of research now suggests that the slow breakup of a supercontinent might have been more than a geological curiosity—it could have helped ignite life as we…

Crumbling Supercontinent Might Have Sparked Life on Earth
How a Shattering Planet May Have Jump-started Life Long before humans pondered the origins of life, Earth’s own tectonic engine was busy reshaping the planet in dramatic ways. A new line of thought among scientists proposes that the crumbling of a long-lived supercontinent could have set off a cascade of environmental changes that ultimately kickstarted…

Scientists Confirm 5-Mmile Wide Nadir Crater Beneath Atlantic Ocean Floor
New Discovery: A Giant Crater Hidden Beneath the Atlantic In a striking fusion of ocean science and planetary history, researchers have confirmed a massive 5-mile-wide asteroid crater buried beneath the Atlantic Ocean floor. Measuring roughly 8 kilometers across, the Nadir Crater is the product of a colossal 66-million-year-old impact that reshaped our planet’s late Cretaceous…
