Nate Silver's New Site Stirs Climate Controversy 335

First time accepted submitter taiwanjohn (103839) writes "One of the first articles on Nate Silver's highly anticipated data-driven news site used flawed data to make its conclusions, according to some of the nation's top climate scientists. Silver's FiveThirtyEight published its first article about climate change on Wednesday, entitled 'Disasters Cost More Than Ever — But Not Because of Climate Change.' But climate scientists are condemning the article and its author, Roger Pielke Jr., saying he ignored critical data to produce a 'deeply misleading' result. The crux of Pielke's article is this: Extreme weather events are costing us more and more money, but that is not because climate change is making extreme weather more frequent or intense. The reason we are losing more money, rather, is because we have more money to lose. Pielke came to this conclusion by measuring rising disaster damage costs alongside the rising global Gross Domestic Product. He also cited a U.N. climate report, along with his own research, to assert that extreme weather events have not been increasing in frequency or intensity."

      In fact, today’s climate models suggest that future changes in extremes that cause the most damage won’t be detectable in the statistics of weather (or damage) for many decades.

      So he isn't a denier exactly. He is saying that damage from natural disasters is not a significant contributor to the damages at this point. Someone making a, data backed, nuanced argument about climate change... seems like its time to get the popcorn.

        Pielke Jr. is a lukewarmer. He accepts that climate science is basically right but thinks the effects won't be as bad as it's being made out to be.

        One of the criticisms I've seen of this paper is that Pielke doesn't take into account the fact that we've built more resilient structures in response to past natural disasters so the fact that the costs remain about the same means either those responses haven't been very effective or that the natural disasters have been getting worse but the additional resilience keeps the costs about the same.

        • by Yaur ( 1069446 )
          But he does talk about exactly that. Specifically about the relationship between per capita GDP and the expected death toll from natural disasters. How do you account for that if the reason isn't better, or at least more widely available, technology and preparedness. Is the counter argument that we are getting better at preventing damage from disasters faster than they are getting worse? That doesn't seem particularly different than his POV.

            You've misunderstood the 538 post. The argument there is simply that higher GDP means there is more GDP available to lose. Ergo, greater losses. Its author claims that technological and preparedness advances are not significant.

          Disclaimer: I am the State Hazard Mitigation Officer for my state...

          Having said that, I can vouch for the fact that every state gets 15% of the cost of the disaster just for mitigating future damages. Everything from acquisition / demolition and elevations for flooding to safe rooms and wind resistant construction for hurricane and tornadoes. This has been going on since the late 80's and is part of the Robert T. Stafford Disaster Relief and Emergency Assistance Act (Public Law 93-288) as amended. Section 404 covers the Hazard Mitigation Assistance and 406 covers Mitigation for Public Assistance (infrastructure).

          http://www.fema.gov/robert-t-s... [fema.gov]

          Currently, our state has over 1,500 properties that are under deed restriction preventing any structures from being built there ever again.

          Title 44 of the Code of Federal Regulations stipulates how the Hazard Mitigation Grant programs are to be implemented.

          http://www.gpo.gov/fdsys/pkg/C... [gpo.gov]

          Add to that the newly (and controversially) enacted Biggert Waters National Flood Insurance Reform Act of 2012 and it makes the NFIP risk based as it should be.

          http://www.fema.gov/flood-insu... [fema.gov]

          So yes, this nation has been actively seeking ways to make communities much more resilient to natural disasters.

          And from an anecdotal point of view having been in emergency management for 15 years, I can say from personal experience that storms are getting more frequent and more powerful.

                  Many people can't handle uncertainty. The theory is sound, more heat = more turbulance. What the IPCC has basically said is that the records are not good enough for a robust statistical conclusion either way. However it should be noted that for over a decade now the acctuaries who calculate risk factors for large reinsurers have been adding a premium for AGW damages. Their main concern is higher tidal surges during storms, such as we saw with Katrina and Sandy.

            Interesting, must just be your neck of the woods, since hurricane/cyclone frequency and energy is decreasing [policlimate.com] on a global scale. Sure, we're spotting more hurricanes/cyclones, but fewer are making landfall and are weaker as well. Perhaps our ability to spot hurricanes out at sea, and classify them correctly is what is getting better, not the actual number occurring.

            Likewise with tornadoes [noaa.gov], which have remained more-or-less constant. Damage caused by F1 to F5 tornadoes is actually dropping; it's the little guys, the F0s, that are increasing damage. Is that because there are more tornadoes? No, there are not more tornadoes. I suggest it is because there is more lightweight construction in/near tornado zones and so damage is happening where in the past it would not - nothing to damage.

          Yes, unlike Antony Watts, Monckton and other "deniers", Pielke sometimes has the balls to put his ideas into a published paper. He is "a" scientists disagreeing with the conclusions of Science in the proper way. IMO his ideas don't amount to a hill of beans but his critsizims do have the welcome affect of strengthening the existing arguments. At the end of the day, robust debate is how Science is supposed to work.

          What I found frustrating about this article is that Nate Silver nicely covered the difficulty of looking at extreme weather events in any short (less than thousands of years) timescales: If mega-storms happen on average every 20 years then it wouldn't be unusual to have a 20 year period that includes two followed by another 20 year period with none, a 10% increase in the chance of mega-storms over that period would be impossible to spot because it's simply too small a period to see that trend.

Until we start cold-fusing He to form C, were only releasing carbon that was at one point or another already in the atmosphere. The earth was not formed with oil reserves in place before there was an atmosphere....

        Yes, humanity evolved and developed to our current state in a period of low atmospheric CO2. Nobody really denies that. It's pretty obvious.

        But...we have no way of knowing if our current civilization -- or even the human species -- can survive a world with those higher CO2 levels. Most people would be in favor of acting to prevent massive natural disasters or the extinction of the entire human race if possible.

        Not that I'm saying humanity WOULD go extinct...I think climate change will be very painful for us, and we should try to mitigate that, but we'll survive regardless. We're pretty damn good at that. But it could certainly set us back a few hundred/thousand years....along with causing millions of deaths...so it's probably a good thing to try to avoid.

Aren't extreme weather events and their relative energy levels easy to gauge and track? Why is this controversial? Either there are more extreme / extremely powerful events, the average energy level increasing, or there aren't. Im sure that (like economists do for inflation), factors that are constant and not constant (like solar output) can be factored.

      Well, here is a major study [ametsoc.org]: 19 different peer-reviewed analyses by 70 climate scientists in 18 separate research groups. Brief summary of their findings:

      • * Climate change helped raise the temperatures during the run of 100F days in 2012’s American heat wave;
      • * drove the record loss of Arctic sea ice;
      • * fueled the devastating storm surge of hurricane Sandy;
      • * heatwaves are now four times as likely;

      However, they also found there are of course still natural events that climate change has not affected, such as:

      • * Britain’s miserable summer in 2012, which was the rainiest in a century;
      • * the Netherlands’ cold spell in 2012;
      • * the drought that devastated America’s corn belt;

Seeking to drive interest (and appease partisans) media come up with false narratives that ignore data. This creates a lot of low hanging fruit for 538 to take the data and point out the narratives are wrong.

When you try to apply that same once over data analysis to areas of serious scientific study you're going to be the one spewing BS.

          What expertise do climatologists bring to this part of the discussion? This is not a question of climatology but of economics. The guys criticizing Pielke are out of their area of expertise on this.

  • My beef with Pielke's conclusions are that they are the same as regular climate "scientists"; namely that a transfer of wealth will somehow save the world. Whether it's carbon credits, or simply giving our money away to have less wealth to lose, global warming proponents simply can't come up with conclusions that allow the status quo to remain in place. When there are some conclusions that point out the advantages of oil spills, recommend increasing the number of wars waged to secure oil resources, show t

    The day before this article came out, the AAAS released a report on The Reality, Risks and Response to Climate Change [aaas.org], and seems to be starting a publicity push on the topic.

    Here's what I see -- the majority of scientists believe that there are real problems with global warming, even if there may be some cyclic effects (heat kills off all the humans, they stop causing problems, everything cools back down).

    So instead we have groups trying to sow disinformation with questions about the incidence of some severe weather events (are we just monitoring better and catching more, in part because humans are in more places, or are they actually increasing), and are the increases in intensity statistically significant?

    And at this point, I've seen some data that might've been tainted (eg, temperature monitors that have had buildings encroach), but the general concensus is that yes, storms are getting worse.

    I'm not going to say his results are completely bunk, as he's likely right in that some of the problems can be explained by how and where people build (eg, in the flood plain -- but the flood plain was resurveyed and is growing in my area ... that might be because of silting up of rivers from construction, it could be because of increased rainfall))

    Where I do fault the article is for referencing a 'recent' UN report that hasn't been released yet (website says "The Summary for Policymakers will be released on 31 March 2014"), so we can't actually get to the underlying data that he's basing his claims on.

    • The flood plain in your area likely didn't grow. What is going on with the flood plains is related to legitimate science and the history of how they were originally developed. Many many of the original flood plain maps were developed with insufficient data and information to draw the kind of conclusions the flood plain maps do. When you run into those situations you don't throw up your hands and just not produce a flood map, you just do the best you can with the limited data you have.

      It's definitely true that a lot of the problem can be explained by things being built in places that they shouldn't be. That's also clearly not the whole story.

      Still, I don't know how I'd approportion the "blame". Sometimes you need both to happen before there's a disaster, sometimes one alone suffices. Sometimes even both together don't yield a disaster. Weather is chaotic. So is climate, though the scale is different. But even in chaos there are attractors. You don't often get snow in June (North o

    Nate made a name for himself doing statistical analysis on events where there are generally two possible outcomes and a fairly limited numbers of possible ways to get there. Sports, voting, etc are ALL yes or no answers with very very limited possible ways to get there.

    Real science on the other hand frequently involves situations where the answer isn't really known and the possible ways to get there are infinite. So rather than evaluating whether the local voters will vote for candidate A or candidate B is an entirely different situation than evaluating whether climate change is increasing the cost of disasters. There are two variables in the first and good data (such as polling) indicating how people in general will vote. With solid statistical analysis this type of situations should be fairly easy to predict IF your data collection is good. He made his name by doing better data picking than the others.

    Climate change disaster levels on the other hand is an entirely different game. Because this is all rather cutting edge science, whether the frequency or size of disasters has gone up (at this time) is a question of open debate in the scientific community. This paper makes blatant assumptions about which side of this debate is right then proceeds to use that assumption as the basis to draw firm conclusions. This isn't good science and it's not good data analysis. Consensus is needed in science if you are going to rely on the conclusions to make predictions on other data sets. And that's exactly the problem, there isn't a yes or no answer to the question there was an assumed answer. There is evidence indicating things and certain scientists may agree or disagree about what that evidence indicates and in time after much research the scientific community will reach a consensus and we'll likely have the real answer with hard evidence at that point.

    Nate should stick to what he's good at, fixed data sets with yes or no answers. He apparently doesn't have the scientific background to realize that not all scientific conclusions drawn in papers are either right nor are they the consensus of the community. After all, any jackass can write a paper and draw conclusions and be completely wrong or even fake data, in fact it happens all to often.

    • Sports, voting, etc are ALL yes or no answers with very very limited possible ways to get there. Real science on the other hand frequently involves situations where the answer isn't really known and the possible ways to get there are infinite

      That's about right. There's a sort of basic ontological fallacy in an article like this. Just because we can construct a question like "To what extent is climate change responsible for the cost of disasters?" it doesn't necessarily follow that it can be answered quan

    The evidence claims that so far, there hasn't been an increase in monetary cost of natural disasters relative to GDP. I'll let other, more informed people tackle this factual issue.* My problem is purely based on faulty logic; at the end of the article, the author extrapolates that this trend of disaster damage being correlated with and caused by increases in GDP will continue indefinitely. But the only evidence cited for the conclusion that climate change won't ever cause increased natural disasters actually says that US tropical cyclones won't significantly increase in frequency and severity for several decades; I found nothing about winter storms/polar vortex, crop loss due to drought, sea level rise, etc. and I'm not even sure how accurately you can extrapolate to tropical cycles in other places, not to mention many of us hope to still be around in several decades. I appreciate that Nate Silver is a great statistician, but this is going to go downhill really quick if the conclusions of articles posted on his site are only tangentially related to the actual statistics.

    *The other disappointing thing is that the author has claimed this before, has been refuted, and hasn't changed his argument even so much as to mention the points made by various people who had rebuttals.

    Someone (in this case Pielke, Jr.) writes up their research then others with expertise in the field get to criticize it, hopefully producing something better ultimately. What is irritating is criticism from people who obviously don't know what they're talking about.

  • Much of the problem is that the Alarmists and the Deniers both like to cherry pick the data to prove their favorite theory. What they do is choose a span of time that proves their point.

    If you look at the last 17 years then you come to one conclusion. If you look at the last 34 years you get another conclusion. That sort of thing.

    This is classic bad science and both sides are doing it. It's annoying.

    • by dave420 ( 699308 )
      Very true. However if you look at the un-cherry-picked data, you see that there is still warming, and all the evidence points to it being mainly due to humanity's CO2 output. Alarmists and deniers can both sod off. AGW is real. Let's not pretend it isn't, or overstate the effects.
  • A few weeks ago, Roger Pielke Jr wrote this [newrepublic.com] in response to similar attacks on him by John Holdren.

    BTW, the United Nations report he mentions comes from the Intergovernmental Panel on Climate Change, the group which shared a Nobel Prize with Al Gore.
  • If "pro" is the opposite of "con" then what is the opposite of "progress"?

    The biggest problem I have with man made global warming scare is that the solution always seems to be bigger government and more taxes. These AGW alarmists go running to Congress to ban this or tax that but neither will really decrease AGW. The way to decrease AGW, if it exists at all, is to create alternatives. Give us something better and people will naturally gravitate toward it because it will be in their best interest to do so.

    By creating legislation to bar people from doing something does not prevent people from breaking the law. Getting caught with the wrong kind of toilet or light bulb in your house is unlikely and there is no real punishment for doing so. So people will break the law. However, if you can convince people that using the wrong kind of toilet or light bulb costs them money then you have a convert.

    What Congress has done is made it difficult to produce energy that is both low in carbon output and profitable. They shut down power plants and coal mines, and stopped issuing permits to drill for oil and gas on federal land. What happened? We buy our oil from other countries where they don't care about spilling oil into the ocean. We put high voltage power lines into Mexico where they don't care how many people die from inhaling the coal soot.

    What we should do instead is allow for the creation of alternatives. There has not been a new nuclear reactor built in the USA for four decades. There might be some new ones being built now but all they do is build new reactors on the same site as the old ones. We need nuclear power. Without nuclear power we must choose between the status quo, continued reliance on fossil fuels, or reverting to a caveman lifestyle.

    I find it laughable about how people will claim that wind and solar will save the environment and give us all the energy we need. Windmills have been shown to kill endangered Golden Eagles and Bald Eagles but Congress lets that happen because wind power is good. Except that wind power does not make a profit. Its economic viability exists only because of taxes, taxes derived from profitable coal energy. Solar power is no different, it kills birds by blinding or burning them and is only held up by taxing the coal industry.

    What happens if Congress is successful in driving the coal industry out of business with taxes? The subsidies for wind and solar energy goes away. Energy prices will triple and people will have to choose between freezing or starving to death. Same goes for gasoline and diesel fuel taxes. If the gasoline and diesel fuel taxes go away then we have no money for the roads.

    I believe AGW is a farce. I believe this because the actions of Congress show me that they are not serious about it so therefore they have not been convinced. If they were convinced of the existence of AGW they would not be acting as they do. If they thought that AGW was a real threat to the environment then they'd be building nuclear power plants. If they were concerned about the environment they they would not be building windmills that kill endangered species. What they have shown me is that their greatest concern is growing the size of government. What better way to grow government than to build an economy that depends on government?

    Subsidies mean people must do as the government says or they don't have a job. Taxes takes money only from those that know how to make money. The best thing that subsidies can do is take money from those that know how to make money and give it to those that know how to make money, which is no better than not taxing them in the first place. But subsidies don't always give money to those who know how to make money, but it does give money to those who know how to do what the government wants.

    If Congress was serious about AGW then they'd stop taxing and spending. Instead they'd provide a legal and economic environment where people with the best ideas on saving the environment and the economy thrive. A good start would be to allow nuclear research to happen. They don't have to give them money, just permission to conduct their work.
