Erik Prince, recently outed as a participant in a C.I.A. assassination program, has gained notoriety as head of the military-contracting juggernaut Blackwater, a company dogged by a grand-jury investigation, bribery accusations, and the voluntary-manslaughter trial of five ex-employees, set for next month. Lashing back at his critics, the wealthy former navy seal takes the author inside his operation in the U.S. and Afghanistan, revealing the role he’s been playing in America’s war on terror.

I put myself and my company at the C.I.A.’s disposal for some very risky missions,” says Erik Prince as he surveys his heavily fortified, 7,000-acre compound in rural Moyock, North Carolina. “But when it became politically expedient to do so, someone threw me under the bus.” Prince—the founder of Blackwater, the world’s most notorious private military contractor—is royally steamed. He wants to vent. And he wants you to hear him vent.

Since the 1997 international accord to fight global warming, climate change has worsened and accelerated — beyond some of the grimmest of warnings made back then.

As the world has talked for a dozen years about what to do next, new ship passages opened through the once frozen summer sea ice of the Arctic. In Greenland and Antarctica, ice sheets have lost trillions of tons of ice. Mountain glaciers in Europe, South America, Asia and Africa are shrinking faster than before.

The world is much closer to running out of oil than official estimates admit, according to a whistleblower at the International Energy Agency who claims it has been deliberately underplaying a looming shortage for fear of triggering panic buying.

The senior official claims the US has played an influential role in encouraging the watchdog to underplay the rate of decline from existing oil fields while overplaying the chances of finding new reserves.

The allegations raise serious questions about the accuracy of the organisation’s latest World Energy Outlook on oil demand and supply to be published tomorrow – which is used by the British and many other governments to help guide their wider energy and climate change policies.

The CIA relied on intelligence based on torture in prisons in Uzbekistan, a place where widespread torture practices include raping suspects with broken bottles and boiling them alive, says a former British ambassador to the central Asian country.

Craig Murray, the rector of the University of Dundee in Scotland and until 2004 the UK’s ambassador to Uzbekistan, said the CIA not only relied on confessions gleaned through extreme torture, it sent terror war suspects to Uzbekistan as part of its extraordinary rendition program.

“I’m talking of people being raped with broken bottles,” he said at a lecture late last month that was re-broadcast by the Real News Network. “I’m talking of people having their children tortured in front of them until they sign a confession. I’m talking of people being boiled alive. And the intelligence from these torture sessions was being received by the CIA, and was being passed on.”

Ahmed Wali Karzai, the brother of the Afghan president and a suspected player in the country’s booming illegal opium trade, gets regular payments from the Central Intelligence Agency, and has for much of the past eight years, according to current and former American officials.

The agency pays Mr. Karzai for a variety of services, including helping to recruit an Afghan paramilitary force that operates at the C.I.A.’s direction in and around the southern city of Kandahar, Mr. Karzai’s home.

The C.I.A.’s practices also suggest that the United States is not doing everything in its power to stamp out the lucrative Afghan drug trade, a major source of revenue for the Taliban.
