EarthThe Competitive Enterprise Institute is suing NASA to release information explaining why the agency revised its global-warming data upward in 2007, after having revised the data downward six weeks earlier. CEI had submitted Freedom of Information Act (FOIA) requests to obtain the information, to no avail. The cover-up may mirror the manipulation of climate-change data by British scientists that came to light last year.

Public opinion about climate change is slipping away from the grasp of the Fourth Estate, to the chagrin of advocates of the theory of manmade global warming.

OceanAs the U.S. Senate prepares to consider enormously expensive cap-and-trade legislation, supposedly aimed at curbing alleged global warming caused by man-made emissions, scientists and policy makers at a conference in Chicago heard from experts in various scientific fields challenging the crumbling assumptions that have provided the foundation for global-warming alarmism.

Industry and government officials continue their desperate efforts to contain an oil leak in the Gulf of Mexico that began on April 20 with an explosion on the Deepwater Horizon oil rig, claiming 11 lives. Representatives from the three major companies involved in the accident — Transocean Ltd., BP America, and Global Business Lines — testified earlier this week before the U.S. Senate Committee on Energy and Natural Resources. Transocean built the rig, BP was its leaseholder and operator, and Global Business Lines supplied the cement used to encase and seal the oil well. Each company blamed the others for failure to follow appropriate procedures and safety precautions.

oil spillThree weeks after the oil rig Deepwater Horizon exploded, the response team is still working to contain three leaks spewing oil into the Gulf of Mexico. The rig was owned by the offshore drilling contractor Transocean, Ltd., and the oil company BP leased and operated it. Both companies are working with nearly a dozen federal agencies as part of the Deepwater Horizon Response Unified Command. So far containment efforts have been fruitless because of the depth and extent of the leaks.
