As we just heard, tomorrow, the Environmental Protection Agency will announce new regulations aimed at cutting carbon pollution. To hear more about that, we're joined by Michael Oppenheimer. He's a professor of geosciences and international affairs at Princeton University. These regulations are the president's most ambitious plan yet to combat climate change. Professor Oppenheimer, from your vantage point, how significant is this announcement?
This week, the Department of Transportation hit Southwest Airlines with a $200,000 fine for touting a fare that did not exist. The carrier had said in a TV ad that customers in Atlanta could fly to New York, Chicago or Los Angeles for just $59. But the bargain fare turned out to be too good to be true.
Southwest, which paid a fine for a similar problem last year, says the ad was a mistake. The airline pulled it as soon as the error was discovered.
