"We have established a global standard for future changes to be measured," said Taro Takahashi, a geochemist at Columbia's Lamont-Doherty Earth Observatory who published the maps with his colleagues in the August issue of the journal Marine Chemistry. The maps provide a monthly look at how ocean acidity rises and falls by season and geographic location, along with saturation levels of calcium carbonate minerals used by shell-building organisms. The maps use 2005 as a reference year and draw on four decades of measurements by Lamont-Doherty scientists and others. The oceans have taken up a quarter of the carbon dioxide humans have put in the atmosphere over the last two hundred years.
Ixchel Ha | A Rain Forest Home Juicy Geography Copenhagen Solutions Lab The Freedom Tower Was Supposed to Be the Greenest Building in America. So What Went Wrong? Under pressure to get a publishing giant into the iconic tower, the site's developers may have sacrificed a core part of its green plans. —James West on Mon. December 8, 2014 6:00 AM PDT Heavy fog blankets Lower Manhattan, including the now-open One World Trade Center.Julio Cortez/AP One World Trade Center, or the "Freedom Tower," as it was formerly known, soars above New York City, finally filling a void left by the 9/11 terror attacks. The tower is now the tallest building in the Western Hemisphere. Then came Sandy. What happened in the basement of One World Trade Center after Sandy is a previously untold—and as yet unresolved—chapter in the site's redevelopment, already dogged by false starts, political squabbling, and cost overruns, involving some of the biggest names in New York City's world of corporate real estate. Breaking the Port Authority's Green-Energy Promise? Then, three years later, Sandy hit. So why didn't the Port Authority replace the fuel cells?

České hovězí míří do Kanady. Zasáhla neviditelná ruka trhu, nebo jsme tak levní? ptá se Pavel Maurer | Glosa Pavla Maurera Copak v té obrovské kanadské zemi nemají krávy? diví se Pavel MaurerFoto: pixabay.com Na českém hovězí si nově budou pochutnávat Kanaďané. Radujete se, že se tak podpoří vývoz českých výrobků? Předevčírem jsem si přečetl informaci Státní veterinární zprávy, že naši zemědělci mohou nově vyvážet hovězí maso a produkty z hovězího do Kanady. Neviditelná ruka trhu v akci. Vložit na svůj web Asi bych měl být na tento náš úspěch hrdý, že? Jen si představuji, jak býček putuje: z pole do kravína, z kravína na jatka, odtud tirákem do logistického centra, pak asi náklaďákem nebo vlakem do nějakého evropského přístavu, lodí přes oceán, následně zase autem nebo vlakem a snad už jen několik málo přestupů než přistane v nákupním košíku a posléze v podobě steaku či hamburgeru nějakému Kanaďanovi na talíři.

A Strange New Gene Pool of Animals Is Brewing in the Arctic - Issue 101: In Our Nature The journey began in spring 2010, just as the sea ice surrounding the North Pole began its annual melt. Two bowhead whales, 50-foot-long behemoths that scour the Arctic seas for plankton, each started from their homes on opposite sides of North America—one in the Beaufort Sea north of Alaska, the other in Baffin Bay on the west side of Greenland. As the summer progressed, sea ice shrank (to its third-lowest cover in the last 30 years), and the whales swam toward each other through the now ice-free passage above the continent. In September, in an inlet some 1,800 miles north of Fargo, North Dakota, where the North American landmass dissolves into the Arctic Ocean, the whales met in the middle. In the last 40 years, the Arctic has warmed by about 3.5 degrees Fahrenheit, more than twice the overall global rise in that same period. While it’s tempting to imagine a strange new Arctic teeming with “grolar bears” and “narlugas,” hybridization comes at a cost.
