Comments Off on Oldest ice core ever dated reveals hidden clues to ancient Earth’s atmosphere

Ice cores hold secrets of what our planet was like millions of years ago, in bubbles preserving greenhouse gases from that time. A Princeton University -led team just revealed the date of ice from the oldest ice core we’ve ever dated, and it’s 2.7 million years old. Breaking the previous record by around 1.7 million years, the ice core could potentially help scientists determine what set off the ice ages . The ice core could help scientists understand more about our planet’s atmosphere millions of years ago. University of California, Berkeley geochemist David Shuster, who wasn’t part of the research, told Science Magazine, “This is the only sample of ancient Earth’s atmosphere that we have access to.” And the levels of carbon dioxide (CO2) in the planet’s atmosphere, according to research on the ice core, may surprise some: they didn’t exceed 300 parts per million. Related: Why scientists are transporting ice from a mountain in Bolivia to Antarctica There are models of our planet’s ancient climate which hinted there would need to be low levels of CO2 to trigger ice ages. But according to Science Magazine, proxies that came from the fossils of animals who dwelt in shallow oceans had hinted at higher CO2 levels. The proxies may need to be re-calibrated if the new ice core dating holds up. Researchers unearthed the ice core from what’s called blue ice in East Antarctica. Science Magazine explained that in blue ice areas, glacial flow has allowed some ancient ice to come up to the surface. As a result, scientists don’t need to drill as deep to obtain old ice core samples in blue ice. The Princeton team hopes to extract still more ice cores from there and geochemist Ed Brook of Oregon State University , who was part of the team, said they could potentially find ice that dates back five million years. Princeton University graduate student Yuzhen Yan presented the research at the Goldschmidt Conference in Paris earlier this month. Scientists from institutions in California and Maine also made contributions. Via Science Magazine Images via Yuzhen Yan, Department of Geosciences

Self-taught designer builds a secret studio under a bridge in Valencia

Comments Off on Self-taught designer builds a secret studio under a bridge in Valencia

Self-taught designer Fernando Abellanas built a studio bedroom in a very unusual place – the underside of a bridge in Valencia, Spain . This tiny moveable workspace has everything he needs – including shelves, a chair and a desk – bolted into the concrete wall of a bridge. The designer built the workspace entirely himself. He installed a hand crank and rails, along which the metal base can move from one side of the bridge to the other. From this hidden space, he can live and work while enjoying complete privacy. Seen from underneath the bridge , the room looks like a small box with foldable sides. Related: You can build one of these tiny backyard offices in less than a week for under $7000 Abellanas hasn’t revealed the actual location of the “cabin”. “The project is an ephemeral intervention, [it will remain] until someone finds it and decides to steal the materials, or the authorities remove it,” he said. Hidden away from passing cars and trains, the space provides the designer with a sense of peace and brings back childhood memories of hiding under a table. + Lebrel | Future Positive Via Archinect

Comments Off on Melting Arctic Ice Opens New Shipping Channel for Petroleum Products

In a move that blatantly disregards the impacts of climate change , shipping companies are taking advantage of melting Arctic ice to cut transportation times for petroleum products. Channel News Asia reports that Japanese shipping company Mitsui O.S.K. Lines recently announced plans to create the world’s first shipping route through the Arctic Ocean starting in 2018. The company would be mainly shipping liquefied natural gas (LNG) from Russia’s Yamal project to markets in Europe and Asia using three specially designed icebreakers for transport. The route is expected to trim 10 days of travel time from the current route through the Suez Canal .

Japan Successfully Taps ‘Flammable Ice’ as an Energy Source for the First Time

Comments Off on Japan Successfully Taps ‘Flammable Ice’ as an Energy Source for the First Time

Japan is faced with a number of challenges when it comes to domestic energy production – the country is the world’s largest importer of natural gas, and since the Fukushima Daiichi nuclear meltdown it has greatly increased its purchase of fossil fuels. In order to find a local energy source, the Japanese Ministry of Economy, Trade and Industry has invested millions of dollars towards exploiting methane hydrate (also known as “flammable ice”) – and today they announced that they’ve successfully extracted it from the seabed for the first time. Methane is known to be an extremely potent greenhouse gas that is 20 times more damaging than CO2. If Japan taps reserves beneath the seabed, it could have catastrophic consequences for the environment.

If you were to believe the mainstream media, the future of transportation is electric. But the conventional gas-powered internal combustion engine (ICE) won’t be going away any time soon.
