Climate Change Checklist

Climate change, or more specifically catastrophic anthropogenic global warming (CAGW), seems to continue to pop its head up from time to time. Labels of "alarmists" and "deniers" are thrown around. Now I am a hardcore advocate of liberty and freedom. I will start any conversation that advocates the necessity of massive govt intervention with skepticism. This is not an anti-science position, this is a pro-freedom position. Now, I may be able to be convinced, but to do so there are a series of things that must be demonstrated as fact to my satisfaction in order for me to even consider supporting the types of "solutions" currently being proposed.

Process Improvements

First, some changes need to be made regarding some process/method issues:

  1. Full audit of surface temperature stations and remediation
    1. Inspections of over 80% of surface stations in the US show that over 70% have a likelihood of over 2ºC of error. That's in the US - how does the rest of the world look?
    2. The adjustment process that supposedly "cleans" this data is not sufficient.
    3. We spend billions of dollars a year on climate research. We can spend a couple million to refactor the vast majority of these stations.
  2. Both raw and adjusted temperature data (with adjustment process) must be available, transparent, and open.
    1. It invites skepticism when the advocates of global warming take raw numbers, adjust them in various ways, release only the end adjustments and leave it at that. 
  3. Scientific studies, papers, models, etc that are published must be reproducible and methods must be made available to the public. 
    1. If we are to have faith in the scientific process on a topic that many advocate for significant changes to our economic system, data, methods, algorithms, etc cannot continue to remain secret and proprietary.
I'm not saying these affect every study or all data but they are prevalent enough to invite skepticism.

Facts Needed

Now, some actual facts that I need demonstrated to me clearly:
  1. The Earth is continually getting warmer
    1. There is currently some question of this due to a plateau over the last 15-17 years.
  2. This warming is NOT simply the continuation of warming that has been happening for the last 400+ years.
  3. The primary driver of the new warming is CO2
    1. Since all the proposed solutions are focused on CO2, then that HAS to be the predominant driver.
  4. The primary driver of the new warming is HUMAN ADDED CO2
    1. Since all the proposed solutions are focused on reducing HUMAN added CO2, then it must be shown that HUMAN caused CO2 is the predominant factor and driver of heat gain.
    2. Don't get me wrong. I'm not claiming that man has NO impact on the climate. Clearly we do. The critical question is whether the anthropogenic CO2 is the PRIMARY driver of climate change.
  5. The result of continued warming will be significantly net negative
    1. Since most proposed solutions advocate significant economic costs, we must be positive that the result from warming will be not just somewhat inconvenient, but significantly bad. 
    2. While a lot of research has gone into the negative consequences of continued warming, I've not seen much of any research into what positives may take place. I am extremely hesitant to believe that there would not be new farming land or expanded migratory patterns in a slightly warmer climate - yet the amount of research into such positives and how they balance out against negatives seems limited.
    3. In addition, a lot of the "negatives" seem ... a little strained. For every story of rising sea levels, there are others that simply allude to the greater proclivity of athlete's foot, jock itch and poison ivy. 
  6. The planet and people cannot adapt to the changes 
    1. I'm hesitant to support massive global economic intervention if it turns out that the changes will take place gradually over hundreds of years. Consider where we were 100 years ago with limited air conditioning, refrigeration, health care, construction practices, access to travel and communication, etc. Now if we are not going to see more than a 1-2ºC increase or most of the significant warming consequences for 100-200 years, then I'm not convinced that we cannot adapt to these changes as they come. 
  7. A free market approach is not viable (i.e. Only potentially viable option is massive govt intervention)
    1. Before we start pushing for coercive govt intervention, I need to be convinced that the free market cannot satisfactorily adjust and mitigate the causes and problems from this process. As the potential consequences become apparent, the money to be made from mitigating them becomes significant.
    2. And I don't accept the explanation that says "We need govt because ... externalities [or tragedy of the commons]." and simply stop. The concept and definition of externalities is insufficient to dismiss the viability of a non-coercive approach to mitigation.
    3. What if someone finds a way to extract CO2 from the atmosphere? What if someone genetically develops a tree that extracts/stores 20 times the standard amount of CO2? 
  8. Massive govt intervention will stop warming
    1. It also needs to be demonstrated that the proposed solutions would actually work. Most of the studies I've seen on the various proposals show virtually no difference in temperature increase over the next 100 years. That's not acceptable.
This last point is key. If the scientific community fixes the process issues I described above and the first 7 facts on this list are demonstrated to me, then I would be convinced that consequences will be dire unless govt intervenes. But if govt is going to intervene, then it better do whatever is necessary to actually effect change. I do not want a significant new tax or a complicated emission trading scheme that places a significant burden on the economy, yet only reduces the rate of warming by 3%. I don't want to advocate for the implementation of a system that will undoubtedly encourage corruption and manipulation if the end result in 100 years is warming only 0.1ºC less severe than had we done nothing. If we believe the consequences are going to be dire if we fail to act, then we need to act in a way that will effect significant change. If the only option is that we all go back to an agrarian society or most of the population will die, then I don't want that reality sugar coated. I don't want to be advocating for some approach that may significantly curb economic growth and prosperity for 100 years but won't actually mitigate the consequences of the warming.

Why skepticism?

Some people ask why we can be skeptical in the face of overwhelming evidence. Well firstly, as I said, I am a hardcore advocate for liberty, so I am going to be hesitant of any call for govt coercion to be expanded. So whereas those that believe that we need to limit growth or think consumerism is bad or that corporations just plain make too much money, who may already advocate for govt intervention for other causes, may need little convincing to get on board with an approach that even may only possibly avoid some calamitous outcome. I and those like me will likely need much, much more convincing because you are asking us to support a policy that directly contradicts our principles.

I'm not going to go into the science debate between the standard CAGW theory and the contrarian views. It would create a huge back and forth dialogue that already exists out there. I will only point out two things: Firstly, there are scientists who perform research that either disproves, questions, or challenges the standard CAGW theory. Some of their research is significant, some of it less so. But the dismissal and "paid by the oil companies" type demonization discredits the opposition to these contrarians. And secondly, the predictive models on CAGW are consistently revealing themselves to be inaccurate - sometimes minorly, sometimes wildly. But the point that skeptics make is not that we know everything about the climate and have proven global warming wrong, but that humanity doesn't know as much about the climate as it thinks it does and the inaccurate models demonstrate that. So before we start putting draconian economic restrictions in place, perhaps we should take off the alarmist hat and gather more data.

In addition, part of the reason that many people are skeptical of CAGW is that it seems very politically driven. Scientists and advocates have been calling on govt to massively intervene in the economy for 60 years for various reasons. Hole in the ozone, rainforests, global cooling, energy crisis, etc. Plus, there is a significant overlap between those that advocate economic intervention for the purpose of social justice or anti-capitalism/anti-consumerism and those that advocate economic intervention in the name of dealing with global warming. It often looks more like a power grab for those in power and a desire to restrain capitalism by others than it does an honest attempt to mitigate a potential problem. 

Also, massive amounts of money are being offered, and as such an entire market has been created, to study the negative consequences of global warming. So we are neither surprised nor convinced that virtually every study finds some bad thing that can be connected, however tangentially, to potentially higher temperatures. Plus, when scientists that question or challenge even some of the most extreme of the global warming claims are shunned, fired or forced to resign from their positions, it creates the impression not of an open arena of debate, but of a closed, self-reinforcing echo chamber. 

Lastly, the advocacy to deal with CAGW often invites skepticism itself. It seems contradictory at times: We have extremely hot/dry summer - it's global warming. We have extremely cold/snowy winters - that's just episodic/localized weather.  A study shows that global warming causes avalanches to increase in one place, but another study shows them to decrease in another. Renaming "global warming" to "climate change" seems strained so that it includes even events that don't have anything to do with warmer temperatures. Plus, some of it is ... well, "alarmist". Countdowns, timers, and counters like the one on the right all come across as over-the-top. I remember reading about how the Green Bay Packers football team, who has a notoriously cold/snowy field through the winter, were going to lose their home-field advantage if global warming continued, and so we must push Congress to act. When advocates stretch to find some connection (or even just some potential connection) to global warming, it starts to seem desperate and lacking credulity. 

Summary and Final Question

So when you put it altogether, you have many advocates of liberty whose default position is skepticism toward calls to support policies that directly contradicts their views. Then, when making the case, there are some scientific processes that have some issues and facts that aren't sufficiently demonstrated. There are also contrarian scientists that challenge or flat-out reject the standard CAGW and issues with models that have struggled with accuracy. Plus you have what seems like a lot of politically driven advocacy and money that may influence scientific work. In addition, you have what appears to be a closed-shop mentality that discourages dissent. And finally, you have a lot of advocacy that seems contradictory or overblown and based on extremely tenuous connections to changes in the weather. No single element may be sufficient to create the skepticism that many feel, but altogether these types of issues cause a lot of the science and advocacy to actually create more skepticism than they allay.

Finally, taking the opposing position, let me also ask you: What is the falsifiability of CAGW? If we see 20 years with continually escalating CO2 levels but no appreciable warming increases, would that, if not prove CAGW wrong, demonstrate that there's something wrong in the models, feedback weights, variables, calculations and in general our understanding of how climate works?

That's really where I feel most skeptics are: Something's not right here and I can't get behind draconian economic measures until it is.

Article Response #3

Article:

Response:
This is a pretty one-sided article to have been written as a communal editorial by the staff. Also, "watching the earth suffer"? Suffer how? How exactly has the earth "suffered" from an average temperature increase of a fraction of a degree? There are predictions that negative things may happen in the future if things continue, but those dire things aren't happening yet (and simply claiming any change is "suffering" doesn't work). More importantly, however, and the reason I chose to comment was to point out that there was no mention of the recent release of emails, code, data and other files from a key climate data organization. Even if you believe the "nothing to see here" attempts to dismiss this revelation, it should at least make us question the true openness of the process. With an issue this potentially significant, whose prescribed solution has such a monumental impact, it only makes sense that all science involved be open, the data available, and the methods described. If scientific experiments and models cannot be recreated by others, then it shouldn't be considered valid and definitely should not be considered as a resource to guide policy. The evidence coming out of the unearthed files indicates the exact opposite of this. It shows intentional efforts to stifle release of data, methods and processes. It contains intentional attempts to eliminate information contributing to the IPCC which is the gold standard reference for all who see global warming as requiring immediate action.
The primary reason this data was as significant as global warming skeptics claim is that for years these skeptics have complained that the scientific process was being abused. They have claimed that scientific journals were influenced in a particular direction, that grants were consistently given to those pushing the agenda, that data was being misused and misrepresented and poorly constructed predictive models based on poor data were being treated as scientific fact. These complaints were usually dismissed as either simply conspiracy theories, or that the complainers were paid by oil companies. With the exposure of these files, at the very least, it reveals that their complaints have some merits. We need to reopen the discussion, verify the data, reevaluate the models and conclusions. It is becoming apparent that the scientific peer-review process is fraught with problems that can lead to significant (and conclusion altering) errors entering into "peer-reviewed studies" that then go on to be referenced across the scientific, media, and political worlds.
From a university paper, and in the wake of this revelation, the editorials should consist of demands that the scientific process relating to global warming be completely opened, transparent, and requiring critical assessment and reproduction by others. We need to make sure that the case for global warming is completely iron proof before we implement measures which would have astronomical effects. If we as a people choose to pursue actions to stop greenhouse emissions, it will be so much more significant than I believe most realize. It will affect individual people so much more than simply shopping with a cloth bag, inflating our tires, and buying energy efficient products. It will be a huge increase on the cost of ALL things. We need to be absolutely positive that it is absolutely essential.

Letter to Congressmen


Revelations of anti-scientific behavior at the CRU (Climatic Research Unit) undermines the justification for cap and trade. The case for human-caused global warming depends on claims made by the UN's IPCC (Intergovernmental Panel on Climate Change), which in turn depend on so-called research by the CRU. 
But please take note . . . 

Emails from the CRU reveal that key advocates of the global warming hypothesis may have knowingly corrupted the scientific process. 
For example… 

CRU researchers may have manipulated temperature histories in order to get the results they wanted. They have systematically refused to expose either their data or their manipulations to testing by the wider scientific community. This kind of testing is a crucial component of the scientific process.
 

Real scientists wouldn't behave this way.

CRU researchers explicitly advised other scientists involved in climate research to delete emails regarding to the UN's IPCC report in an intentional effort to avoid Freedom Of Information (FOI) requests. This is a blatant attempt to cover their tracks and avoid exposing bias, misrepresentation or outright fraud.

Real scientists wouldn't behave this way.

CRU researchers have also demonstrated a keen desire to silence critics by influencing scientific peer review process, as well to thwart and resist FOI requests for the data involved and the methods used in their studies which advocate for global warming legislation like cap and trade. The scientific process requires peer critiques.

Real scientists wouldn't behave this way.

The hypothesis that rising atmospheric CO2 should lead to global warming seems plausible. However, it's not an open and shut case, and the scientific process is famous for refuting seemingly plausible ideas. Now the practices of the CRU have set back the global warming hypothesis many years – perhaps to its starting point. The C02 hypothesis needs further, OPEN testing. It can't be taken for granted because it sounds reasonable, nor because it came from people with titles and degrees.

Your responsibility in this matter seems clear . . . 

You must reject the cap and trade bill, and craft no further policy until we all have better evidence from which to work.

In fact, I believe it would be reasonable that all government funded (i.e. grant) studies release not only the full results of their studies to the public, but also the entire set of data, methods and source code used to attain their conclusions. This would allow those that are skeptical to recreate the experiments, and to confirm or disprove the findings. It would also allow more sets of eyes to "peer review" the study. With the possibility of studies pushing policy, we need to ensure that there is some means to limit the impact of politicians who have an agenda from pushing money to organizations that share their views, whose studies reinforce the agenda of the politicians. 

I will be watching to see if you act responsibly on this matter, and I will be discussing your re-election with fellow voters in light of how you handle this issue.
