Grand Canyon Rocks Preserve a 1.2-Billion-Year Record of Earth And The Moon (opens the original)
Read excerpt
Roughly 1.25 billion years ago, the mudflats bordering an inland sea became the origins of the reddish-orange layers of the Hakatai shale. This subtropical landscape on the ancient continent of Laurentia periodically became a landscape of evaporating moisture resembling a modern sabkha or playa. As climate conditions changed, the sediments accumulated in rhythmic patterns. Today, the same patterns can be traced in outcrops 65 kilometers apart, and preserve a record of a time when an Earth day wa
Rich US Neighborhoods Are More Likely to Burn in Wildfires, Study Reveals (opens the original)
Read excerpt
Wildfires that ravage developed areas of the US tend to hit a particular kind of neighborhood: suburban, owner-occupied, and relatively well-off, new research has found. Wildfires in the US aren't just a problem for communities near remote forests – they are literally in people's backyards, especially for people who live on hillsides near wildlands on the outskirts of urban areas – which is exactly where rich neighborhoods tend to be. "These urban fires consistently occur in suburban, high-incom
Giant Trenches Reveal Caves Up to 150 Meters Deep Beneath Australia's Nullarbor Plain (opens the original)
Read excerpt
Sometimes geologic features are obvious; faults can leave giant cracks in the ground, enormous boulders in a field are clear proof of glaciers dropping them as they melted, and defined layers of colorful sediment in a rock cut clearly show an area's depositional history. And sometimes Earth's features are really, really subtle – so much so that they might be impossible to see with the naked eye. Scientists recently found the latter on Nullarbor Plain, a vast, treeless desert in Australia. This h
Earth May Be Harboring a Hidden Stash of Water, Up to 1,800 Miles Below The Surface (opens the original)
Read excerpt
The phrase "water is life" is true – water makes all known life on Earth possible. It's also a key component in lubricating the super-slow movement of Earth's mantle layer, hydrating those rock layers enough for them to ooze and slide past each other. This is important to the tectonic cycle, which in turn helps regulate climate over geological time. That water also allows for important recycling of rocks and volatile compounds through the mantle. "Liquid water is the key component of Earth's hab
The Atlantic Ocean Has a Hidden 'Heat Valve' That Controls Earth's Temperature – And It Could Be Closing (opens the original)
Read excerpt
Our relatively stable global climate is governed by an incredibly complex set of factors, all interacting with each other in dynamic and changeable ways – but there are a couple of really big, key players in that system. The Atlantic Meridional Overturning Circulation (AMOC) is one of them. This system of ocean currents redistributes heat from tropical regions up to cooler places, and cools warmer waters down too (important for sensitive marine life like corals). Nutrients that ocean species rel
