PBS – the network that conservatives have regularly attacked  for “liberal bias” for more than 40 years – finally put that myth to rest tonight by airing a one-sided interview with climate change denier Anthony Watts . The former weatherman-turned business owner and blogger Watts, was given close to ten minutes of uncontested airtime to spout his disinformation about climate change, without any retorts from actual climate scientists.
Update: Forecast The Facts  launched a petition calling for PBS Ombudsman Michael Getler to investigate  whether the segment met PBS' standards.
Watts freely admitted in the interview  that he is not a climate scientist, but said that he has a problem with climate scientists because, as Watts says, they are using “faulty data.”
Watts should know a thing or two about faulty data, as he was recommended to PBS  reporter Spencer Michels for an interview by the disinformation specialists  at the Heartland Institute .
Here is a brief snip from the PBS Newshour interview :
SPENCER MICHELS: What's the thing that bothers you the most about people who say there's lots of global warming?
ANTHONY WATTS: They want to change policy. They want to apply taxes and these kinds of things may not be the actual solution for making a change to our society.
SPENCER MICHELS: What are you saying? That they're biased essentially or motivated by something else? What?
ANTHONY WATTS: There's a term that was used to describe this. It's called noble cause corruption. And actually I was a victim of that at one time, where you're so fervent you're in your belief that you have to do something. You're saving the planet, you're making a difference, you're making things better that you're so focused on this goal of fixing it or changing it that you kind of forget to look along the path to make sure that you haven't missed some things.
I started looking into the idea that weather stations have been slowly encroached upon by urbanization and sighting issues over the last century. Meaning that our urbanization affected the temperature. And this was something that was very clear if you looked at the temperature records. But what wasn't clear is how it affected the trend of temperatures. And so that's been something that I've been investigating. Anyone who's ever stood next to a building in the summertime at night, a brick building that's been out in the summer sun, you stand next to it at night, you can feel the heat radiating off of it. That's a heat sink effect. And over the last 100 years our country, in fact the world, has changed. We've gone from having mostly a rural agrarian society to one that is more urban and city based and as a result the infrastructure has increased. We've got more freeways, you know more airports, we've got more buildings. Got more streets, all these things. Those are all heat sinks. During the day, solar insulation hits these objects and these surfaces and it stores heat in these objects. At night it releases that heat. Now if you are measuring temperature in a city that went from having uh maybe 10% of um, non-permeable surface to you know maybe 90% over 100 years, that's a heat sync effect and that should show up in the record. The problem is, is that it's been such a slow subtle change over the last 100 years. It's not easy to detect and that's been the challenge and that's what I've been working on.
SPENCER MICHELS: Well in a way you're saying that the records aren't accurate, the data isn't accurate.
ANTHONY WATTS: I'm saying that the data might be biased by these influences to a percentage. Yes, we have some global warming, it's clear the temperature has gone up in the last 100 years. But what percentage of that is from carbon dioxide? And what percentage of that is from changes in the local and measurement environment?
There’s really only one way to take Watts’ statements, and that is to infer that he believes climate scientists are fools. For him to be allowed to go on the air and make an unchallenged statement that climate scientists are wrong because they didn’t factor in that buildings and asphalt surfaces retain heat is both infuriating and demeaning.
The concept of heat absorption by different surfaces, colors, and objects is a subject that some school systems teach to children as young as 6 years old  – and yet Watts believes that climate scientists with years and years of education and real-world experience forgot about this elementary school lesson.
The urban heat island theory has been debunked repeatedly, including by the Koch-funded BEST analysis . Despite his March 2011 statement that, “I’m prepared to accept whatever result they produce, even if it proves my premise wrong,” Watts continues to peddle the urban heat island  theory to this day, and continues his attacks on the Koch-funded study in the interview.
But that isn’t the only jab that Watts took at climate scientists:
SPENCER MICHELS: Has this issue, I know you think it's been oversold and scare tactics have been used. Do you think it's become too politicized?
ANTHONY WATTS: Oh, it's definitely become too politicized. In fact, some of the scientists who are the leaders in the issue have become for lack of a better word, political tools on the issue.
Again, it is ironic that a man recommended by the Heartland Institute would have the audacity to refer to anyone as a “political tool.”
Ultimately however, the blame for this shoddy piece of “journalism” lies with PBS. They fell into the trap that says that there are two sides to every story. But that is not always the case, and it certainly isn’t the case with climate change .
Bill Nye put it best recently when he told CNN : “I appreciate that we want to show two sides of the stories — there’s a tradition in journalism that goes back quite a ways, I guess — but the two sides aren’t equal here. You have tens of thousands of scientists who are very concerned and you have a few people who are in business of equating or drawing attention to the idea that uncertainty is the same as doubt. When you have a plus or minus percentage, that’s not the same thing as not believing the whole thing at all… We in the science education community chip away at this problem all the time. We have an enormous population of people in the United States that don’t believe in evolution, the fundamental idea in all of life science. It would be like saying, I don’t believe in earthquakes or something. The analogies are disturbing.”
Nye is absolutely right with his analysis of media coverage, and PBS has now fallen into the same disgraceful journalistic tactics purveyed on Fox News and, as Nye pointed out, on CNN.
