Siberian traps. Image: jxandreani Twenty-five million years ago, life on Earth was shattered by the Permian-Triassic event, the most devastating loss of biodiversity in the history of our planet. Over a period of only 60,000 years, about 90 percent of the marine animals and 70 percent of the land species died, which owes its macabre nickname "The Great Dying" to …

Fast, unpredictable failures in Earth's magnetic field could happen again

As the invisible shield of power around the Death Star surrounds, the Earth's magnetic field protects our planet from the hottest and most static charged particles the Sun can throw in our path. This shield – the natural product of molten iron swirling around the core of the planet – has turned its back on billions of years, preventing the …

Study says Earth's magnetic field has shifted rapidly in the past, and when it does happen again, it could be catastrophic

One of the main reasons that life thrives on Earth is that it is protected from something of the coarser phenomenon of space by something we can not even see. It's the magnetic field that creates our planet, and there's much more to it than telling your compass which direction you're going. <p class = "canvas-atom canvas-text Mb (1.0em) Mb …

Extremely rare blue diamonds lurk deep in the Earth's core

The world's rarest diamonds were forged hundreds of miles below their surface, scientists announced Thursday. A team of geologists and gemologists from Australia and the US analyzed 46 blue diamonds, including one from South Africa, which was sold for $ 25 million in 2016, to determine that the gems are at depths of 410 miles below the Earth surface are …

The global population has already completely consumed Earth's natural resources for 2018

The world's population consumes far more than the finite natural resources that the planet produces each year. Earth Day, the day when the natural resources of the planet are fully consumed in a given year, will be earlier than ever on August 1, 2018. "Earth's ecosystem is remarkable, and if managed properly, it can sustain human civilization indefinitely," writes the …
