The modern meltdown of the Antarctic Ice Sheet mirrors the frozen continent’s big thaw after the last ice age ended 20,000 years ago, a new study finds. New ice core records from West Antarctica show the huge ice sheet started heating up about 20,000 to 22,000 years ago, 2,000 to 4,000 years earlier than previously…
Seventy years after its invention, the Buckminster Fuller Institute has organized a competition challenging graphic designers, visual artists, and citizen cartographers to create a new and inspiring interpretation of the Dymaxion Map.
EnvironmentalScienceDegree.com is an enormously helpful platform for anything and everything environmental. Their mission is to help environmentally conscious professionals and those seeking an education in the field to move forward. Recently, they have compiled a list of 101 Web Resources on Climate Change. As an incredibly complex and controversial topic, it is difficult to find…
A new map of the seafloor off the coast of Iberia—the region of Europe that includes Portugal and Spain—has revealed what could be the birth of a new subduction zone. Subduction zones happen when tectonic plates—the large rock slabs that make up the Earth’s crust—crash into one another. The edge of the heavier plate slides,…
The solid iron core is actually crystalline, surrounded by liquid. But the temperature at which that crystal can form had been a subject of long-running debate. Experiments outlined in Science used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt. Seismic waves captured after earthquakes…
Any kind of underwater diving involves process for that very reason. There’s the early-morning wake-up, the weather check, the gear check (masks, fins, regulators … check). And then there’s the dive site approach – whether you’re walking in from the shore or taking a boat to some far forgotten reef. Diving Lake Untersee is just…
Geological detectives are piecing together an intriguing seafloor puzzle. The Indian Ocean and some of its islands, scientists say, may lie on top of the remains of an ancient continent pulled apart by plate tectonics between 50 million and 100 million years ago. Painstaking detective work involving gravity mapping, rock analysis, and plate movement reconstruction…
A new study indicates that the last interglacial period may give us a picture of where the planet is headed now, as greenhouse gases increase and temperatures rise. Results from the NEEM deep ice core drilling project, led by the University of Copenhagen, show that during the Eemian period, between 130,000 and 115,000 years ago,…
A study last year found unusually high levels of the isotope carbon-14 in ancient rings of Japanese cedar trees and a corresponding spike in beryllium-10 in Antarctic ice. The readings were traced back to a point in AD 774 or 775, suggesting that during that period the Earth was hit by an intense burst of…
It’s hard to imagine how this teeny little rock — it’s not even a whole rock, it’s just a grain, a miniscule droplet of mineral barely the thickness of a human hair — could rewrite the history of our planet. But that’s what seems to be happening. This piece of Zircon, an extremely durable mineral…
