      Covers 3.8 to 2.5 billion years ago. "If you were able to travel back to visit the Earth during the Archaean, you would likely not recognize it is the same planet we inhabit today. The atmosphere was very different from what we breathe today; at that time, it was likely a reducing atmosphere of methane, ammonia, and other gases which would be toxic to most life on our planet today. Also during this time, the Earth's crust cooled enough that rocks and continental plates began to form."

  16. 09-06-03 The Cost of Gaining U.N. Support in Iraq (
      "...The Bush administration is reportedly preparing to ask Congress for a further $60-70 billion to fund ongoing operations in Iraq, and the cost of the first year of war and occupation looks set to run upward of $100 billion and that's before the serious investment required for reconstruction even begins."

      "...the French and Germans have made no secret of the fact that they believe events in Iraq have vindicated rather than undermined their earlier opposition to the war no weapons of mass destruction have been found and the terror threat appears to have increased rather than decreased as a result of the war. Even the Joint Chiefs of Staff has reportedly slammed the Pentagon's postwar planning as woefully inadequate."

      "Not only has the U.S. lost more troops in the postwar period than during the invasion itself; the fact that the number of American soldiers wounded in action currently averages 10 a day speaks to the scale of the resistance they're encountering." "While they'd agree with the principle of transferring power to the Iraqis, the 'Old Europeans' are going to demand that the UN, rather than the Bush administration, be given authority over the political process in the interim. And that may be more than the administration is willing to concede at this point." 9-03

      " 'The presence of a massive U.S. Embassy -- by far the largest in the world -- co-located in the Green Zone with the Iraqi government is seen by Iraqis as an indication of who actually exercises power in their country,' the International Crisis Group, a European-based research organization, said in one of its periodic reports on Iraq." 04-06

  18. Study: Arctic Was Once Tropical (Washington Times)
      "First-of-its-kind core samples dug up from deep beneath the Arctic Ocean floor show that 55 million years ago an area near the North Pole was practically a subtropical paradise, three new studies show."

      "Millions of years ago the Earth experienced an extended period of natural global warming. But about 55 million years ago there was a sudden supercharged spike of carbon dioxide that accelerated the greenhouse effect."

      "Scientists already knew this 'thermal event' happened but are not sure what caused it. Perhaps massive releases of methane from the ocean, the continent-sized burning of trees, numerous volcanic eruptions." 05-06
