Ocean acidification worst in 300 million years, study finds (+video) The oceans are becoming more acidic faster than they have in the past 300 million years, a period that includes four mass extinctions, researchers have found.

Then, as is happening now, increases in carbon dioxide in the atmosphere warmed the planet and made the oceans more acidic. But while past increases in the atmosphere's carbon dioxide levels resulted from volcanoes and other natural causes, today that spike is due to human activities, the scientists note. "What we're doing today really stands out," lead researcher Bärbel Hönisch, a paleoceanographer at Columbia University's Lamont-Doherty Earth Observatory, said in a news release. New evidence suggests Stone Age hunters from Europe discovered America - Americas - World.
New archaeological evidence suggests that America was first discovered by Stone Age people from Europe – 10,000 years before the Siberian-originating ancestors of the American Indians set foot in the New World. A remarkable series of several dozen European-style stone tools, dating back between 19,000 and 26,000 years, have been discovered at six locations along the US east coast. Three of the sites are on the Delmarva Peninsular in Maryland, discovered by archaeologist Dr Darrin Lowery of the University of Delaware. One is in Pennsylvania and another in Virginia.
A sixth was discovered by scallop-dredging fishermen on the seabed 60 miles from the Virginian coast on what, in prehistoric times, would have been dry land. The new discoveries are among the most important archaeological breakthroughs for several decades - and are set to add substantially to our understanding of humanity's spread around the globe. A Conversation with Peter Thiel. Francis Fukuyama: I’d like to begin by asking you about a point you made about there being certain liberal and conservative blind spots about America.
What did you mean by that? Peter Thiel: On the surface, one of the debates we have is that people on the Left, especially the Occupy Wall Street movement, focus on income and wealth inequality issues—the 99 percent versus the 1 percent. It’s evident that both forms of inequality have escalated at a very high rate. Probably from 1973 to today, they have gone up faster than they did in the 19th century. The rapid rise in inequality has been an issue that the Right has not been willing to engage. It tends either to say it’s not true or that it doesn’t matter. In the history of the modern world, inequality has only been ended through communist revolution, war or deflationary economic collapse. Francis Fukuyama: And it will require countless environmental permits, litigation, and so on.
Peter Thiel: Yes. Paul Krugman Nails It On The French Election. The Fukushima Syndrome - Martin Freer. Exit from comment view mode.

It was the tsunami, caused by the largest earthquake ever to strike Japan, that killed more than 16,000 people, destroyed or damaged roughly 125,000 buildings, and left the country facing what its prime minister described as its biggest crisis since World War II. Yet it is Fukushima that is habitually accorded the “disaster” label.
In fact, although what happened was shocking, the events in the hours and days after a giant wave slammed over the nuclear plant’s protective seawall might be interpreted as a remarkable testament to nuclear power’s sound credentials.
