What is really catching the attention of Goldman Sachs now is the outlook for agricultural prices. Or as Jeff Currie, head of commodities research at the US bank, says with disarming cheer: “We think we could go into crisis mode in many commodities sectors in the next 12 to 18 months . . . and I would argue that agriculture is key here.”

Now, to some readers of the Financial Times, that observation might seem odd. After all, inhabitants of the western world typically spend far more time worrying about the price of petrol for their car, rather than the price of wheat or corn. And when western investors do think about “commodity shock”, their reference point typically tends to be the 1970s oil crisis.

The FBI has awarded a nearly $1 billion contract to Lockheed Martin to help create a massive computer database of people’s physical characteristics as part of an effort to better identify criminals and terrorists.

The overall deal is worth between $850 million to $1 billion and could run as long as 10 years, said Thomas Bush, the FBI’s assistant director of the Criminal Justice Information Services Division.

The widows whose political activism was largely responsible for the establishment of a commission to investigate the September 11 attacks say a new book revealing the backstory of the 9/11 Commission proves that their initial concerns about its executive director were correct and demonstrate the need for another investigation.

Philip Shenon, who covered the proceedings for the New York Times, has written a new book, The Commission: The Uncensored History of the 9/11 Investigation, which was released Tuesday. The book reveals the close ties between commission executive director Philip Zelikow and White House advisers Karl Rove and Condoleezza Rice.

Global warming this century could trigger a runaway thaw of Greenland’s ice sheet and other abrupt shifts such as a dieback of the Amazon rainforest, scientists said on Monday.

They urged governments to be more aware of “tipping points” in nature, tiny shifts that can bring big and almost always damaging changes such as a melt of Arctic summer sea ice or a collapse of the Indian monsoon.

“Society may be lulled into a false sense of security by smooth projections of global change,” the scientists at British, German and U.S. institutes wrote in a report saying there were many little-understood thresholds in nature.

The FBI is gearing up to create a massive computer database of people’s physical characteristics, all part of an effort the bureau says to better identify criminals and terrorists.

But it’s an issue that raises major privacy concerns – what one civil liberties expert says should concern all Americans.

The bureau is expected to announce in coming days the awarding of a $1 billion, 10-year contract to help create the database that will compile an array of biometric information – from palm prints to eye scans.
