The recent release of hacked e-mails between climate scientists at the University of East Anglia has shed new light on the 2007 accusation that Phil Jones, director of the university’s Climatic Research Unit, helped cover up flawed data used in an article claiming to provide evidence for global warming.

The data in question came from a 1990 article written by Jones and Wei-Chyung Wang, a professor at the State University of New York, Albany. The article, published in the journal Nature, examined how much of the global warming measured recently has resulted from the spread of cities, which have higher temperatures than unpopulated areas.

Billionaire Ted Turner is set to receive 88 Yellowstone National Park bison from Montana that were supposed to be put on public or private lands.

The animals, now housed at a joint federal-state quarantine compound in southern Montana’s Paradise Valley, are part of a state program geared toward placing disease-free animals on public or tribal lands.

NRG Energy Inc., one of Delaware’s largest industrial polluters, struck a deal with state regulators that will require it to shut down three of its four Indian River Power Plant generating units by 2013 in exchange for being allowed to continue to use one of its turbines without air emissions scrubbers for three more years.

A 2009 court order had mandated the shutdown of two of the plant’s turbines by 2011 and required the scrubber installation on a third turbine.
