You could call it progress in media bias. For years, liberal journalists have blamed Team Bush for the death of hundreds in Hurricane Katrina. The major media found that theme of fatal incompetence simply irresistible. Time’s Michael Grunwald, who has written in-depth articles and a book about the Army Corps of Engineers, is bringing the focus back to long-standing government policies over decades. But even Grunwald is using harsh language that Time magazine would usually disparage as talk-radio bluster. He said "Hurricane Katrina was a man-made disaster.

Monday’s Lou Dobbs Tonight on CNN gave attention to filmmaker Phelim McAleer – whose film Not Evil, Just Wrong premieres this Sunday and challenges Al Gore’s Inconvenient Truth – in the aftermath of his recent attempt to get Gore to respond to the British High Court ruling that there are nine factual errors in An Inconvenient Truth. But McAleer’s microphone was cut off as he tried to get Gore to answer for some of these inaccuracies and whether the former Vice President was trying to correct his mistakes. After a report by correspondent Casey Wian – who showed a clip of the exchange between McAleer and Gore, and who also mentioned some of the inaccurate points in An Inconvenient Truth about polar bears and Hurricane Katrina – Dobbs hosted a debate segment between McAleer and Fred Krupp of the Environmental Defense Fund.

McAleer pointed out that many of the environmental scientists pushing global warming theory were pushing global cooling theory decades earlier: "And the same environmentalists who are now saying it is warming, 20 and 30 years ago were saying we're going to have an ice age. I'm old enough to be at school and I was told that we're going into a new ice age."

On Sunday’s "Good Morning America," weekend host Bill Weir highlighted the fourth anniversary of Hurricane Katrina and insisted that the storm "really tainted the Bush legacy." The GMA anchor talked to liberal author Jason Berry and asked if there was an intentional effort to not rebuild poor neighborhoods in New Orleans. "Is that a deliberate political move," he asked.

Attempting to draw a contrast between former President Bush and Barack Obama, Weir speculated, "But talk about the change in the presidential administration. You know, the response to Katrina really tainted the Bush legacy. But have you noticed any change in tone, any optimism under President Obama?" (Weir is the journalist who hyperbolically insisted during the President’s inauguration that "even the seagulls must have been awed" by the event.)

NPR ombudsman Alicia Shepard has focused again on what NPR reporters say on Fox News. Reporter Mara Liasson infuriated the liberal listeners of the taxpayer-funded network when she proclaimed on Tuesday's Special Report that "Cash for Clunkers is like a mini-Katrina here," Liasson said.

Hinting at but not explicitly charging President Obama with eco-hypocrisy, CNN weatherman Rob Marciano chided the chief executive for flying out to Iowa and back just for one Earth Day speech. Marciano took to the camera shortly after 10 a.m. EDT for a weather report. His comments came on the heels of Heidi Collins describing Obama's agenda for marking Earth Day [audio available here]:

ROB MARCIANO, CNN meteorologist: Is that the 747 Air Force One I see on the tarmac getting ready to go fly to Iowa for Earth Day?

HEIDI COLLINS, CNN anchor:  Yup.

MARCIANO: I mean, it's a pretty big carbon footprint just to make a speech in front of a windmill.
