CBS's Face the Nation Sunday spent fifteen minutes discussing climate change and amongst other things its impact on tornadoes - in particular the EF-5 that hit Moore, Oklahoma, last week.
As not one global warming skeptic was invited to participate in the panel, I've taken the liberty of getting opinions from some of the leaders on the realist side of the debate (video follows with commentary and full transcript of the segment at the end of the post):
First to respond was Competitive Enterprise Institute's Christopher Horner:
The intro description of the panel that they assembled -- to tell you how bad things will [sic] get -- is spot on, but for the "will," admirable in its candor.Vivid memories of many calls w/producers: "Well, we're looking for someone to say [X]"...
Thanks Chris.
Next up was was Watts Up With That's Anthony Watts:
I’ve made several responses about this need to try to link tornadoes to climate change over the years, and this is just another sad claim by activists that can easily be falsified by the data. A list of my previous responses follows, but let’s take one instance from the interview where Dr. Heidi Cullen says:So, basically, add additional heat to the atmosphere, suddenly, you’re now adding more moisture to the atmosphere, so we know that certain kinds of extreme events are going to happen more frequently.I don’t even need to look at long term data to falsify this nonsense, just looking at seasonal variations is more than enough. If extreme weather events like tornadoes are more common due to more heat being in the atmosphere, then you’d expect more tornadoes when it is warmer, right?First let’s look at solar isolation versus temperature on a yearly basis in the norther hemisphere. Plotted below, from the middle of tornado alley is the daily temperature data for Manhattan, Kansas for the year 2006. Compared to the normalized insolation from the sun. In the spring the temperature mostly lies beneath the energy. After the peak energy it tends to be above the energy curve due to the time lag.
Graphic by John Kehr, The Inconvenient Skeptic.Note that peak temperature lags peak solar insolation. Solar insolation is a function of Earth’s orbit around the sun. Insolation peaks with the summer solstice, typicall [sic] on June 21st each year, but temperature continues to rise after that.You can plot insolation vs temperature for just about any northern hemisphere city and see the same result, it is a well known relationship. Temperatures peak around late July to early August.By Dr. Cullen’s claims of more heat being in the atmosphere, we’d expect to see tornadoes peak around August, right? The real world data says the opposite:
Tornadoes peak in May and June, prior to the peak temperature, which is a proxy for heat in the atmosphere.So if more heat in the atmosphere produces more localized exterme weather events, as Dr. Cullen insinuates, we’d see peak tornadoes aligned with peak temperature. But, we don’t.Dr. Cullen is being an advocate, rather than a scientist, but we already knew that since she works for a privately funded advocate organization, Climate Central.
Thanks Anthony.

Next up was Real Science's Steve Goddard:
David Bernard (from Miami) is complaining about hurricanes. Florida hasn't had a hurricane strike for eight years, which is their longest hurricane-free period on record, by far.2012 US temperatures were no warmer than 1921, before NCDC jacked them up.79% of the US is below normal temperatures this year:
Thanks Steve. Next up was WeatherBell.com's Joe Bastardi:
Warming world...For the past 17 years IT'S NOT WARMING, and the past 4 since the PDO flip has taken effect it's cooling. So the notion and assumption that we are currently warming should be rejected. This is classic climate cycle theory based on the oscillations in the oceans. No matter how complex one wished to make it, the cooling tropical Pacific is cutting the feet out from under the temp. rise. Once the AMO goes, it will drop further.The CO2 is a red herring beyond what it's small contribution is and it will always be "boxed in" by the greater forces around it. I am miffed cause I got beat over the head 5 years ago by these climatic ambulance chasers when I proposed the big test (the last time was a challenge to Bill Nye) to see where it goes. Well it's not going up. And to just give these guys the high ground that it's warming is absurd. The cooling will last until the resultant change in the PDO, then AMO, is compensated for by the atmosphere just like the warming lasted while that was occurring. The sun is a factor that has to be accounted for, but I am strictly talking the oceans.All one needs do is FALL IN LOVE WITH THE WEATHER and watch how it behaved in the 1950s. Dave Bernard's comment assuming warming is disappointing to say the least. Cullen is one thing. She makes some of the most inaccurate statements about weather events I have ever heard. But Bernard ought to know it's the AMO for the Atlantic, and this will pass just like the previous cycle did.
And one final thought: for some reason, no one on this distinguished panel chose to bring up tornado data released earlier this month that should have had a significant role in the discussion.
As USA Today reported May 10:
The USA in the past 12 months has seen the fewest number of tornadoes since at least 1954, and the death tolls from the dangerous storms have dropped dramatically since 2011. [...]The seven people killed from May 2012 to April 2013 is the fewest in a 12-month period since five people died in September 1899-August 1900, according to Harold Brooks, research meteorologist with the National Severe Storms Laboratory in Norman, Okla.The year-to-date count of tornadoes is probably approaching the lower 10% of all years on record, said Greg Carbin, warning coordination meteorologist with the Storm Prediction Center in Norman.The reason: An unusually cool weather pattern from the Rockies to the East Coast. "Generally, the lower the temperature and/or the drier the air, the lower the number of thunderstorms," said AccuWeather meteorologist Alex Sosnowski.
As Christopher Monckton marvelously wrote in December 2012:
The fact is that despite continually rising atmospheric CO2 levels, there hasn't been any global warming in over a decade.
But none of the geniuses Schieffer brought on to discuss this issue Sunday had the scientific integrity to mention it.
Also of note was Cullen talking about the current atmospheric CO2 level as being a "steroid" to temperatures and Shepherd agreeing. Unfortunately, nobody mentioned that in the history of our planet, our current CO2 level is actually quite low.
In a paper called "Geologic Global Climate Changes," Nasif Nahle observed in March 2007:
Scientific studies have shown that atmospheric Carbon Dioxide in past eras reached concentrations that were 20 times higher than the current concentration. Recent investigations have shown that the current change of climate is part of a larger cycle known as climatic lowstand phase which precedes a sequential warming period known as transgression phase. The purpose of this evaluation is to demonstrate that the Earth is actually cooling, in the context of the total geological timescale, and that the current change is equivalent to a serial climate phase known as lowstand.
In prehistoric times, during the Permian, in the Palaeozoic Era, for example, the concentration of Carbon Dioxide dropped below 210 ppmV...The change of atmospheric temperature at the time of the Permian was around 10 °C. By comparison, the current change of global temperature is only 0.52 °C while the concentration of atmospheric carbon dioxide is 385 ppmV. If the global temperature is dependent on CO2, then the change of temperature at present would be around 10 °C or higher, as it was during the Permian Period.From the early Triassic to the middle Cretaceous, the concentration of atmospheric Carbon Dioxide was similar to its current density. From the late cretaceous to the early Miocene, the concentration climbed above 210 ppmV. During the Holocene period, the concentration has oscillated from 210 ppmV to 385 ppmV.It is possible that the concentration of atmospheric CO2 will increase normally in the course of the next 50 million years to 1050 ppmV or 2500 ppmV. [...]Scientists have also observed that the concentration of atmospheric CO2 increases during periods of warming. However, an increase in temperature always precedes an increase in carbon dioxide, which generally occurs decades or centuries after any change of temperature. We have not observed an increase in the concentration of Carbon Dioxide to have preceded a period of warming. This latter phenomenon occurs because when oceans absorb more heat from an increase in the amount of direct solar irradiance incident upon the Earth's surface, they release more Carbon Dioxide molecules into the atmosphere. Nevertheless, most drastic increases in CO2 concentration occur decades or centuries after the oceans have warmed up. For example, the present increase of atmospheric Carbon Dioxide was caused by an extraordinary increase in solar activity in 1998 which warmed up the El Niño South Atlantic Oceanic Oscillation.
Not surprisingly, real science and historical facts such as these weren't part of the discussion on Face the Nation Sunday. Only junk science and hysterical propaganda:
BOB SCHIEFFER: And welcome back to FACE THE NATION Part Two. For Page Two today we thought we'd explore a subject that affects everyone--the weather. So we have convened a panel of experts to tell us how bad things are going to get this summer and beyond. Heidi Cullen is the chief climatologist for Climate Central which is an independent organization of scientists and journalists who study the climate, now it's changing; Jeffrey Kluger is an editor-at-large for TIME Magazine. He co-wrote this week's cover story on the Oklahoma Tornado; David Bernard is with us in person today. He usually joins us from his weather watching post at WFOR TV, our CBS affiliate in Miami; and Marshall Shepherd is the president of the American Meteorological Society. He is in Atlanta this morning. Doctor Shepherd, I want to start with you because we've had floods. We've had droughts. We've had tornadoes. We've had superstorms. It's cold when it ought to be warm and it's warm when it is supposed to be cold. I guess, you know, if it starts raining frogs that's probably the only thing we haven't had so far. What is happening? Is this something different? Is this just a cycle? What's going on here?J. MARSHALL SHEPHERD (American Meteorological Society/University of Georgia): Yeah, well, it really-- and-- and I'm a professor at the University of Georgia and here in-- in Georgia, we've actually had almost all of those examples that you just gave-- tornadoes in Atlanta. We flooded in 2009, a really bad drought. I-- I think it depends on which-- which phenomenon you talk about. Certainly, as I often say, weather is your mood and climate is your personality, so on any given day you can have really cold weather or really violent weather, but the scientific literature, including our recent AMS Climate Change statement, does suggest that our climate is changing and I think we can say some things about certain weather phenomenon and climate phenomenon that are more linked to this climate change and we are in a different climate system now. Almost every weather phenomenon happens in a warmer and more moist climate. And so I-- I think we do see some changes in our climate and some responses in our weather. I-- I-- I think it's a bit premature to say that there is a definitive link between that Moore tornado last week and-- and-- and climate change. But I think more research is needed there.BOB SCHIEFFER: Well-- well, Jeff, is there any consensus about what is causing this?JEFFREY KLUGER (TIME): Well, in the case of the tornadoes, as Doctor Shepherd says, we're reasonably sure that there is no link. And-- and in fact, to the extent that climate change plays a role, the variables kind of neutralize one another, you get an increase in warm moist air, which feeds tornadoes, but you also get a decrease in the updraft, the vertical shear, so they sort of cancel each other out. I think what we see though the fact that we crossed four hundred parts per million of CO2 in the atmosphere just last week. This is the highest it's been since the Pleistocene era when there were forests in Greenland and sea levels were sixty feet higher than they are now. As recently as 1958, it was only three hundred and fifteen. So, we have supercharged, super accelerated CO2 input into the atmosphere and this I think is what's driving so much of the mood or the-- the personality, the climate change variables we see. BBOB SCHIEFFER: Doctor Cullen, there's no question that it's getting warmer. We have a graphic here that just shows 2012 was the hottest year on record. It shows how much hotter it was. The entire country was affected. Is this going to get any better or is it going to get worse?HEIDI CULLEN (Climate Central): It's not going to get any better if we don't do anything about it. I mean right now we've added about a degree and a half of extra warming to our atmosphere, the planet is that much warmer. And so what we are talking about is how does that extra degree and a half affect our day-to-day weather? And so right now I'd say that, you know, the jury is still out as to how global warming will affect tornadoes, which of those two variables will win out. But when it comes to things like heat waves, when it comes to things like heavy rainstorms, drought, wildfires, we know that, you know, the-- the atmosphere is on steroids, if you will. So basically, you know, we know that we'd have to deal with weather-related risks. We live in a country that has always seen extreme weather. We're basically moving in a direction where we're going to see more and more of certain of these extremes and-- and as we heard before that-- that stuff is really expensive.BOB SCHIEFFER: Well, but what is causing this?HEIDI CULLEN: So, basically, add additional heat to the atmosphere, suddenly, you're now adding more moisture to the atmosphere, so we know that certain kinds of extreme events are going to happen more frequently. So the heat wave that would only happen, say, one in a hundred years is now going to happen say once every fifty years. The statistics, if you will, the likelihood of seeing a certain kind of extreme increases just by the virtue of the fact that the planet is warmer, and then also when it comes to storms there is more moisture in the atmosphere. Those storms can now rain down more heavily and basically at the same time we've got more people in harm's way. We saw that with-- with Moore, Oklahoma, as well. So, you know, this combination of-- of amplifying risks, more people in harm's way, a warmer planet with more moisture to-- to bring more storms into-- into play, it basically just increases our vulnerability across the boards.BOB SCHIEFFER: All right. Dave Bernard, you're our man on the hurricane watch. We talked to you many times during hurricane season and the bad news is NOAA has come out with hurricane season predictions that say it could be worse this year than it-- than it was last year. They're predicting a likelihood of, I think, thirteen to twenty name storms of which seven to eleven could become hurricanes.DAVID BERNARD (WFOR Miami): Well, you know, the key here is we have been in a climate pattern for the last twenty years of excessive storms in the Atlantic Basin. That climate pattern, Bob, is still in place, so that's the reason why we're looking at an elevated number of storms. Now, of course, the key everywhere year is, where do these storms go? That's one thing that we really can't tell ahead of time. Last year, there were nineteen storms and basically we had Isaac hit Louisiana and, of course, Superstorm Sandy. But the majority of the storms, they stayed out to sea. But with a forecast like that and the potential for more land falling storms, I-- I think there could be even a-- a greater impact and what we learned from Sandy and even going back to Hurricane Katrina and basically what Doctor Cullen was saying, we have more people now living on the coast than ever before. So the impact potential really is that much greater and we have to learn how to mitigate against these storms. Clearly, that was not done in the Northeast. We'd gone so long without a significant hurricane there. We've seen that in other areas. We have to learn to live with these storms and going forward since we don't know exactly where this climate pattern may take us. With a warming world we have to learn to adapt to these storms as well.BOB SCHIEFFER: Well, Doctor Shepherd, let me just cut to the chase here. Are we doing something here on Earth that is causing the weather to change or is this just one of the cycles that-- that what we go through?J. MARSHALL SHEPHERD (American Meteorological Society): Yeah, this is a question I often get, Bob. Of course, I mean, it's amazing to me when someone comes up to me and says "Doctor Shepherd, the climate change is natural." I say, of course, it does. I should send my degree back to Florida State University, if I didn't know that. But what's most important about that is that on top of this natural variability, as-- as Heidi mentioned, we now have a steroid. Think of a basketball player. I mean I'm a big basketball fan. We were in the middle of the playoffs right now. A basketball ten feet high think of it this way: Climate change is actually adding about a foot to the basketball floor so that more people can dunk the basketball. There's just more amplification. That warmer and more moist climate is amplifying, as-- as Heidi mentioned, some of the weather systems that we see. And one quick point I want to make. I often get the question: well, what is the big deal? One and a half degree? Well, if our child gets a one-and-a-half or a two-degree fever that may not sound like a lot, but our body responds to that and our climate system as well. But the scary news is we're talking about an additional three- to ten-to-fourteen degrees perhaps in some models in the next one hundred years.BOB SCHIEFFER: So Jeff?JEFFREY KLUGER (TIME): And one of the problems is the problem is getting worse, as Doctor Shepherd says. We have now baked in another fifty parts per million of CO2 in the atmosphere. Even if we turned everything around now, what's in the pipeline already is going to increase up to four fifty and at a rate of 5.4 billion tons of CO2, the U.S. puts into the atmosphere every year and 2.4 million pounds per second that the world pumps in. We're getting a level of consensus on thousands of peer-reviewed studies over decades that have established the-- the connection between human activity and this kind of climate change and we have to face the reality that the problem exists and now we have to address it.BOB SCHIEFFER: Well, what is the human activity then?JEFFREY KLUGER: Well, the human activity principally is fossil fuels. Now finally, everybody attribute this is to cars principally. Actually forty percent of all of the contribution is our homes, our office buildings and things of that nature. Fossil fuels do make a difference. And we are actually making progress, the slow transition to renewables, the increase in-- in mileage standards for cars. All of this is bringing these numbers down, but all that's doing is sort of putting out the fringes of the wildfire that's blazing. We have to get to the heart of it and began to shut it down.BOB SCHIEFFER: And this is not just something that the United States that's happening in the United States this is happening worldwide.HEIDI CULLEN: That's what's so tricky about this problem, right? It's-- it's kind of the ultimate tragedy of the commons in the sense that we all contribute to the problem and so it-- it really, you know, someone once said that climate change is really about a million little fixes and it's also the biggest procrastination problem in the sense that the longer you wait to fix it, the tougher it gets to fix so the sooner we start the better off we are.DAVID BERNARD: And I really think adaptation is going to be the key. We've already baked in this CO2. We can't get rid of that. So we have to learn to live with the way the climate is going and that means responsible development. We can't keep building in the same places that maybe more prone to floods. I live in Miami Beach. We're dealing with sea level rise. That's something we're going to have to think about going forward in this new reality.BOB SCHIEFFER: Doctor Shepherd, what-- what I find kind of interesting is kind of like-- it's kind of like the country is divided in half. The western half of the country going through these droughts, which bring on the fires and all of that. Yet, on the eastern side of the country we have all these floods that are-- that are going on right now. Is there any reason, scientific reason, that it's kind of divided the country in half like this?J. MARSHALL SHEPHERD: Well, it-- it is. One of the things that we've always known in the literature is that places that are drier likely will get more dry and places that are wetter will become more wet. If-- you have to really look at how weather patterns occur weather patterns occur as big waves in the atmosphere. We call them scientifically raspy waves. And so if you look at a weather map, for example, on any given day in terms of weather you'll have one part of the country that is cool and wet there and a big sort of dip in the wave pattern, a trough, as we call it. Meanwhile, you have-- you'll have a ridge of high pressure and nice weather in another part of the country. We're-- we're it's gorgeous here in Atlanta right now and I was watching the Braves and Mets last night in New York, pouring down rain and cool the last couple of days. That kind of take that sort of wave pattern and think about that from the perspective of climate. So you're not going to have the same type of response everywhere. That's why it's important to keep that in mind when we hear "Well, gee, it's really cold this last couple of weeks, what are you guys talking about, global warming?" You cannot say anything about the overall climate system by looking at the last couple of days or where you live. Boy, I wish I could actually predict my stock portfolio based on the stocks the last two weeks, the last two months. We can't do that. We cannot do that with our climate.BOB SCHIEFFER: You know-- and as is always the case around my house, we say when everything else goes wrong and top of it the toilet breaks. I mean, the least the-- the thing you would least expect. In the middle of all this, Jeff, NOAA recently had one of its weather satellites go off line. What is the status of our technology?JEFFREY KLUGER: The status of our technology is precarious and funnily it's easy to fix it. We have two major weather satellites hovering over the eastern half-- half-- East and West Coast, the GOES East and GOES West, they're called. They're in geosynchronous orbit. They just hover there. We have five polar satellites. These are all set to go down at one form or another, to wink out between 2015 and 2016. The earliest we can replace them will be those very years, which means that if there's any lag at all in launching construction schedules we're going to be struck blind. This we saw the wages of back during Sandy when the GOES East satellite did go down for a few weeks just as this storm was brewing and we did not predict the sharp left hook Sandy took into the Eastern Seaboard that is exactly what did the sixty-five billion dollars worth of damage. It took the European system to weigh in and inform us that this was about to happen. Now we had just enough assets in place, a spare satellite in orbit to swing into position and take care of this. But if we don't take care of this now and allocate the necessary money we are going to be vulnerable to whatever is out there.BOB SCHIEFFER: I take you, you would endorse that?HEIDI CULLEN: I-- you know, I couldn't have said it better. Right now ninety percent of the data that goes into our weather models comes from satellites and this infrastructure it's critical, it's our eyes in the sky and if we lose it we're flying blind. And we desperately, I mean, as a country that sees a lot of extreme weather across the board we need strong forward-looking forecasts.BOB SCHIEFFER: I'll let you close it out here, Dave. What do we look for?DAVID BERNARD: Well, I think as we go through the next few months everybody needs to keep in mind that regardless of where our climate is heading in the next fifty, one hundred years, the hurricane season it's here now and that's hurricane preparedness week and as we saw it last year, everybody from Maine to Texas, you need to be ready, you need to have a plan.BOB SCHIEFFER: I guess we can't say have a nice day to close out this segment, but thank you all for being here.
