Conservatives who avoid MSNBC like the plague missed a rare moment of clarity about our political culture this morning when his liberal partner Mika Brzezinksi fed Joe Scarborough one of the great straight lines of all time. While discussing last night’s Senate Democrats’ all-night talkathon devoted to climate change, Mika praised it by saying how glad she was that, “they’re trying to have a conversation.” That allowed the man who sometimes plays the role of the network’s token Republican while at others is its resident GOP critic of conservatives, to launch into a comic rant mocking both Brzezinski’s platitudes and the Democrats’ stunt.

Hollywood won’t talk about climate change. The media won’t talk about climate Nobody will talk about climate change. Thank God. Thank God, these brave Democratic senators are risking the wrath of the mainstream media and the Hollywood elites to talk about climate change …Damn the New York Times! They will not talk about climate change. It’s up to these men and women. This is 2014’s version of Mr. Smith Goes to Washington.”

Scarborough’s sarcasm was, of course, right on target. No matter what you think about the question of human involvement in possible shifts in global temperatures, the idea that it was up to a few dozen Senate Democrats to get the issue on the national agenda is a joke. The mainstream media has spent the last decade or more highlighting the topic at every possible moment and treating the most extreme conclusions produced by alarmist environmentalists as unquestioned truth while popular culture has embraced the global warming agenda with a religious fervor that brooks no dissent.

The problem the Democrats were addressing was not a lack of information about the subject but the fact that while a majority may believe humans are involved with warming, they are either skeptical of the extremists’ claims or don’t care that much about it. That was one of the main conclusions to be drawn from a Pew Research Center poll published in January that showed that global warming ranked 19th on the list of top policy priorities for Americans. Indeed, even the amorphous concern about “dealing with moral breakdown” ranked higher than warming, which was embraced by only 29 percent of those polled as something that demanded immediate action. A separate NBC News/Wall Street Journal poll that came out the same week in January showed that addressing climate change ranked dead last among the 13 topics listed with only 27 percent saying it was a priority.

Why do Americans feel that way? Perhaps its because, as Scarborough noted, they’ve been having the Al Gore party line about the world on the verge of melting incessantly drilled into them for a decade and, even if they agree about the role of human activity, are sensibly skeptical about claims about Florida and Manhattan being under water in 20 years. Perhaps they also find a scientific theory championed by advocates who are unwilling to debate their findings and hell bent on silencing critics as members of the Flat Earth Society or worse to be somewhat suspicious. They also don’t like the fact that the discussion about the topic has taken on a theological rather than a scientific tone in which every conceivable weather event involving heat, cold, wind or precipitation is used to justify a preconceived conclusion about the climate that brooks no opposition rooted in reason or statistics.

Many also understand that some of the most popular measures associated with the climate change caucus would have a devastating impact on the American economy, particularly in states where coal is a major source of employment. Just as important, they have understandably come to associate this movement with Luddite objections to sensible projects like the Keystone XL pipeline that don’t hurt the environment but produce jobs and more energy to allow this country to become less dependent on oil from outside North America. That’s why the most Democratic senators up for re-election this year — Alaska’s Mark Begich, Louisiana’s Mary Landrieu, Arkansas’ Mark Pryor and North Carolina’s Kay Hagan — wanted no part of the show.

It should also be noted that the hours of talk and carefully prepared visual aids were unrelated to any upcoming legislative purpose. In other words, what the Democrat were doing was playing to their base without having to defend a specific proposal or to pretend that what they were about wouldn’t cost Americans dearly in exchange for vague and unproven promises about their future.

But whatever it is that they were doing, the most risible aspect of this spectacle was the notion that it was needed to raise awareness about climate change. As Scarborough’s sarcastic rant made clear, there are few topics on which Americans have heard more in recent years than this one. Their children are inculcated with the global warming catechism in schools. Their movies, plays and television shows are also peppered with references to what is considered right thinking on the issue and abuse for those who dissent.

Americans are smart enough to know that whatever might be slowing happening to the climate, it is a far less pressing matter than issues relating to the health of our economy, jobs, terrorism, education, ensuring the survival of entitlements like Social Security and Medicare, the budget deficit, health care, taxes and crime (to note the top 10 in the Pew poll).

If Senate Democrats want to devote their energies to something useful, they might try their hand at working just as hard on those issues (on most of which they have done nothing as part of their main task of thwarting all legislation passed by the Republican-controlled House of Representatives) rather than pulling an all-nighter to talk nonstop about an issue that Americans have had shoved down their throats for years.
