Why doesn't Obama talk about "climate change" anymore?

The NYT environmental reporter Elisabeth Rosenthal has a long "news analysis" piece titled "Where Did Global Warming Go?" It veers all over the place but I think the nut of it is that Obama's not talking about it anymore. Here are paragraphs 4 and 5:

Though the evidence of climate change has, if anything, solidified, Mr. Obama now talks about “green jobs” mostly as a strategy for improving the economy, not the planet. He did not mention climate in his last State of the Union address. Meanwhile, the administration is fighting to exempt United States airlines from Europe’s new plan to charge them for CO2 emissions when they land on the continent. It also seems poised to approve a nearly 2,000-mile-long pipeline, from Canada down through the United States, that will carry a kind of oil. Extracting it will put relatively high levels of emissions into the atmosphere.

“In Washington, ‘climate change’ has become a lightning rod, it’s a four-letter word,” said Andrew J. Hoffman, director of the University of Michigan’s Erb Institute for Sustainable Development.

And here's the last paragraph, #24:

In private, scientific advisers to Mr. Obama say he and his administration remain committed to confronting climate change and global warming. But Robert E. O’Connor, program director for decision, risk and management sciences at the National Science Foundation in Washington, said a bolder leader would emphasize real risks that, apparently, now feel distant to many Americans. “If it’s such an important issue, why isn’t he talking about it?”

What's in all those other paragraphs?

1. Poll numbers show a decline in Americans' belief in the catastrophic predictions about global warming.

2. There's nothing about poll numbers in other countries, but governments in other countries are adopting measures aimed at pushing back the climate.

3. In the U.S., the right wing has made "skepticism about man-made global warming into a requirement for electability, forming an unlikely triad with antiabortion and gun-rights beliefs," and polls show a partisan tilt to the skepticism.

4. People in other countries are getting annoyed at us for going about our selfish ways and not getting with the climate-fighting agenda. And Bill Clinton said "I mean, it makes us — we look like a joke, right?"

So, you can see, the point here is: Hey, Obama, get with the program. Look to the world and its opinion of us. Isn't that supposed to be your thing? Instead, you're acting like a right winger. That's so disgusting! Bill Clinton thinks you look like a joke.
