For years, the term “Anthropocene” has been used to informally describe the human era on Earth. But new evidence suggests there’s nothing informal about it. We’re a true force of nature — and there’s good reason to believe we’ve sparked a new and unprecedented geological epoch.
What lies beneath the deep blue sea? So much more than you might think.
In 2005, an intense heatwave struck a mountaintop rainforest in northeast Australia. Accounts of the event were rather apocalyptic: birds dropping dead out of the sky; entire patches of forest withering to a crisp. But the biggest casualty of all was a snow-white furball that scampered amongst the branches at the…
A team of scientists has unearthed the fossil remnants of a tropical forest on the arctic island of Svalbard, and it could help explain one of the most dramatic climate shifts in Earth’s history.
Water, water everywhere, but how on Earth did it get here? Many scientists believe that Baby Earth formed dry and was later soaked by an onslaught of extraterrestrial impacts. But a new study challenges that view, arguing that our planet has had water from the start. In fact, we have have inherited it from the tiny…
It took 2,500 seismometers, 23 explosive blasts, and countless earthquakes, but researchers now have a much better idea of what the magma chambers look like deep below Mount Saint Helens. The weird bit? It looks like it shares a magma chamber with a whole field of local volcanoes.
The ancient Earth was a pretty miserable place. But from this eruptive, radiation-blasted, asteroid-pummeled wasteland, life did arise. Now, scientists have uncovered a tantalizing clue that Earth’s first hardy colonizers appeared much earlier than we thought.
After decades of neglect, Venus might just be making a comeback. Late last month, NASA announced five finalists for the next low-cost space probes; two of them are missions to Venus.
Scientists have just uncovered one of the largest tsunami events in the geologic record, and naturally, it started with an epic splash. 73,000 years ago, the eastern flank of Cape Verde’s Fogo volcano collapsed into the sea, kicking up an 800-foot wave.
Earth is the only planet in our Solar System where life is known to exist. Note the use of the word “known,” which indicates that our knowledge of the Solar System is still in its infancy, and the search for life continues. However, from all observable indications, Earth is the only place in our Solar System where…
We all know that major storms can wreak havoc, flooding cities and decimating infrastructure. But there’s an even bigger worry than wind and rain: space weather. If a massive solar storm hit us, our technology would be wiped out. The entire planet could go dark.
Georgia Tech paleoclimate scientist Kim Cobb made a disturbing discovery when she saw her 8 year-old daughter’s state-issued science textbook.
It’s a dark and stormy night, 28,000 feet over the Midwest. Just after 10:30 PM, I’m standing aft of the cockpit of a NASA DC-8, while lightning flashes outside the cabin windows.
California’s Lake Tahoe is known for being blue—really, really blue. And for a long time people assumed that bright color was because it was so clear. We now know that isn’t the case after a study on the lake revealed something weird.
Carbon emissions aren’t just changing the climate — they’re making it harder to solve crimes. As our atmosphere fills with fossil carbon, scientists will have a tougher time using radiocarbon dating, a standard forensic technique, to analyze human remains and wildlife tissues.
Phytoplankton may be microscopic, but that doesn’t mean we can’t see them. Just look up: These little critters are brightening up cloudy days around the world.
The Pacific Northwest is due for a continent-rending earthquake. Experts believe the odds of a Big One happening in the next half century are about one in three, the odds of a Very Big One roughly one in ten, and that, in either case, we are disastrously unprepared.
There’s been much debate these past few years over the cause of the so-called global warming “hiatus”—a pause in the overall uptick up of Earth’s temperature due to cooling at the surface of the Pacific Ocean since the early 2000s. Did climate warming stop? Nope, we just weren’t looking deep enough.
Remember that brilliant picture of the Colima Volcano in Mexico we shared yesterday? The photographer, Cesar Cantu Quiroga passed along something better - a time lapse of the eruption, which shows just how awesome the volcano’s eruptions are.
The Colima Volcano is located in Mexico, Colima, and since November 2014, it’s been highly active.
