ClimateGate (My Climate Confession; or the war with deceivers and with self-deception)

December 4th, 2009 4 comments

[I note that Jeffrey Tucker has kindly put a post linking to this from the main Mises Economics Blog pages: A Libertarian Green Responds to Climategate.  Readers are invited to note the comments over there, and to comment where their fancy may suit them.]

Aaah, the Great Climate Hack!

I`m flattered by a back-handed request to weigh in – with something “public,
humble and honest” – with my thoughts on the ramifications of the mass
of emails hacked from the UK East Anglia University Climate Research Unit.

Well, I`ll try, despite the fact that, in the case of this Rorschach blot, people are not only starting with their own predilections and views, but given the reams of commentary already written by others, people aren`t really even commenting on the same Rorshach blot.

[May my readers try to be honest with themselves as well. I`ve been
holding back, in part because the parameters of the story are quite
large, but also simply not to spoil the fun as calm, reasoning climate
scientists at LvMI enjoy a “delicious” bout of self-congratulatory -“see, we knew all along that `climate change` exists only in the hearts of perfidious, conspiring men!” I mean, what`s the point of weighing in where minds are already made up?]

My take?  A few basic points, and maybe a few links at the end:

  • Whatever GCH may reveal about certain climate scientists or their behavior, it does not, of course, alter the climate itself. Nor does it have any significant  impact on the enormous array of data across the world that points to ongoing climate change, a human role in it, and concerns about the possible climate impacts as we proceed to double and triple the atmospheric levels of CO2 by combusting the world`s accessible fossil fuels.
  • The Climate Hack is certainly egg on the face of some climate scientists – although this has been spun ridiculously out of context (much criticism is clearly simply wrong, though those who find the whole thing “delicious” have a tough time looking past the sources they prefer to read) – but the
    implication that the science is nothing but a conspiracy is an obvious
    fantasy
    . The political amateurisness of the scientists alone tells us that. (If any readers honestly need help in finding their way through the fog – self-deluded or deliberate – of the “skeptics” here, please let me know.)
  • Austrians/libertarians already knew that much of the climate science is politicized,
    especially here
    , not simply because of public funding, but chiefly because all
    parties – fossil fuel investors seeking to protect a generous
    status quo, enviros, politicians & bureaucrats, and those seeking
    greater advantage or more investment climate certainty – are seeking to
    steer government in particular directions
    , in ways that will significantly affect all of us. A further factor in such politicization is the simple difficulty that laymen (and scientists) have in wrapping their own heads around the climate science, and for which personal confirmation may take a lifetime. Personal predilections to hate “environazis”and the like, on the one hand, or to disdain evil capitalists, on the other, has nearly everyone looking for whatever scrap of science confirms their existing views and/or suits their political preferences.
  • The discord among scientists and attempts at gate-keeping are part
    and parcel of science – publicly-funded or not – but because of the
    political importance of climate science, we need greater, not less,
    transparency.
    The apparent efforts at gate-keeping (seeking to influence what gets published in peer-reviewed journals and what appears in IPCC reports) is what seems most objectionable, but there has been plenty of disagreement and change in views even in the dominant view; the science is and will always remain unsettled. All dissenters have found ways to make their views known, most of which have been examined and found wanting, and few dissenters have mutually coherent views.What has happened is that scientists who are extremely concerned about climate change have felt that political action is needed, and that dissenting views are dangerous distractions, and have made efforts to limit “distractions”. Such a belief appears to have been well-founded, but acting on it in this way a strategic mistake. Greater openness is required for publicly-funded research, particularly here where there is a strong, established and resistant rent-seeking class that seeks to minimize the science and to distract public discussion. While the efforts of climate scientists to provide data to and to address the arguments of “skeptics” would necessarily entail a distracting amount of attention, it is apparent that they simply need to grin and bear it.
  • Much – though not all – of the “skepticism” is clearly
    revealed as an extended, deliberate campaign by fossil fuel interests
    , dressed up
    in part by scientists who are non-experts in the field they criticize, with support by “conservatives” and “libertarians” who prefer a massive unmanaged meddling with global ecosystems (and defense of a government-entangled, pro-fossil fuel firms status quo) over a likely expansion of government.
  • The controversy – and the hurdles it raises in the
    legislative/policy agenda – presents an opportunity for those who 
    prefer market-friendly policies to shift the discussion away from the
    current porky, bureaucrat-friendly cap and trade package
    that even climate scientists
    like NASA`s James Hansen and enviros widely disdain. 
  • International cooperation will continue, because informed citizens, corporations and leaders worldwide all desire such action. Efforts at cooperation will continue to be bedevilled by gamesmanship issues common with open-access resources – over fairness, efficiency, good will and verifiability.
  • Domestic climate legislation
    and regulation remain in the cards and will eventually pass, in one form or another
    – not simply because science is
    persuasive and the risks of inaction high, but also because a
    coalition of firms and gate-keepers want such legislation. We are witnessing a fight over government between certain powerful fossil fuel interests and a coalition of other interests (and the politicians that cater to them all); the fossil fuel interests are fated to lose their long predominance.

Humbly and honestly,

Tom

In which I try to help Bob Murphy figure out just what the heck I’m talking about (when I say he’s entangled in a partisan, rent-seeking game)

May 12th, 2009 4 comments

I recently posted a copy of a comment to Bob Murphy, trying to explain Roe Romm’s attack on Bob’s effort to explain some of the stupidity behind “green” or “clean” jobs, and how it is that Bob just doesn’t seem to be (and is in fact not) above the fray.

Well,  Bob has professed that he just doesn’t “get it”, so I copy here both his question and my further attempt to explain why hired guns tend to be treated as if they are hired guns:

 

Blogger Bob Murphy said…

TT,

I am being serious, I have no idea what your point is. Are you truly asking me why I didn’t go into IER’s funding at my Heritage talk? Of course you can’t possibly be saying that.

But then, I don’t know what you are saying. It seems with you I cannot win: Even if you agree with everything I say in a particular op ed or panel appearance–and even if I don’t take an issue on whether AGW is serious–you still devote 95% of your post to all the things I “conveniently” left out.

And what is particularly interesting is that I didn’t have the time to make the points you mention.

So, given that I was under the gun because others went long, which sentence(s) should I have taken out of my 5-minute remarks, and what should I have replaced them with?

I am not being sarcastic or “in your face.” I really have no idea if I am supposed to take your criticisms on this seriously, as if you are actually saying I should have said Y instead of X.

May 9, 2009 2:40 AM

Blogger TokyoTom said…

Bob, thanks for the response – but I’m puzzled that you’re not following me.

1. I often agree with you and occasionally give you a full thumb’s up comment. If you need more pats on the back, I’m happy to try harder on that. But I generally comment when I disagree with you, and think I have something to offer. YMMMV.

2. Presumably you understand well the Austrian and public choice perspectives on how government is frequently misused by favored insiders for private gain, or, when opposition is more organized, on how government becomes a public battleground between opposing interests with respect to resources that are not privately owned (so the expression of private preferences in the market is not possible or is frustrated).

3. Given this, can you see that while you might think you’re being even-handed, others see you as a hired hand for the long-dominant rent-seekers (the investors & industries for whom it is profitable to use our largest shared, open-access commons – the atmosphere – as a free dumping ground, while shifting risks on an uncontracted-for manner to others)?

4. And given such a perspective, can you understand that others – particularly others like Joe Romm who have been deeply involved in the rent-seeking battle – have a hard time actually listening to what you have to say, since they tend to see you as a wolf in sheep’s clothing? (Indeed, they may be so convinced that they’re “right” that they may not even notice that, like Joe, they are spokesmen for a little Baptists-bootleggers coalition of their own!)

5. As for your own position, have you really failed to notice that when speaking for IER you’re in the pay of the biggest “skeptic” rent-seekers left with respect to our largest open-access commons – the coal lobby? (Not oil, as Romm has overlooked that Exxon has stopped funding IER.)

And have you noted that Rob Bradley never talks about rent-seeking by coal (including their desire to have government fund billions for “clean” coal), while happily blocking from the “Master Resource” blog guys like me who point out these inconsistencies and some of the nonsense comming from his co-bloggers and readers?

6. Note that this point is not, as [other commenters deleted] would have it, an ad hominem; rather it is a fundamental, Austrian meta-argument about the misuse of government and the frustration of preferences when squabbles over government take place in the stead of private transactions (for clearly identified and defendable private property.

7. Of course I don’t expect you to mention in your Heritage talks your funding by IER/coal, but since you’ve brought it up, perhaps you might wish to consider – particularly if you wish to actually influence those who now have their fingers in their ears – how to address this issue. Here`s hoping that you strive to step above the fray and aim for more transparent balance.

Regards,

Tom

Paul Krugman: "The only way we’re going to get action … is if those who stand in the way of action come to be perceived as not just wrong but immoral."

August 1st, 2008 2 comments

Paul Krugman reaches the above conclusion in his August 1 New York Time op-ed, which asks “Can This Planet Be Saved?”, while discussing the latest work by economists on the cost-benefit analsys of taking action to mitigate potential climate risks – this time by Harvard`s Marty Weitzman, whose work I have discussed several times before).

The op-ed certainly shows the frustration of Krugman, who was one of more than 2500 Nobel Laureate and other economists who in 1997 signed  the “Economists’ Statement on Climate Change” that  acknowledged the conclusions of the preceding IPCC report (that man was having a discernable influence on climate), asserted the economic feasibility of greenhouse gas reductions without harming the American economy, and recommended market-based policies.  Key parts of the op-ed are the following:

What’s at stake in that fight [over environmental policy], above all, is the question of whether we’ll take action against climate change before it’s utterly too late.

It’s true that scientists don’t know exactly how much world temperatures will rise if we persist with business as usual. But that uncertainty is actually what makes action so urgent. While there’s a chance that we’ll act against global warming only to find that the danger was overstated, there’s also a chance that we’ll fail to act only to find that the results of inaction were catastrophic. Which risk would you rather run?

Martin Weitzman, a Harvard economist who has been driving much of the recent high-level debate, offers some sobering numbers. Surveying a wide range of climate models, he argues that, over all, they suggest about a 5 percent chance that world temperatures will eventually rise by more than 10 degrees Celsius (that is, world temperatures will rise by 18 degrees Fahrenheit). As Mr. Weitzman points out, that’s enough to “effectively destroy planet Earth as we know it.” It’s sheer irresponsibility not to do whatever we can to eliminate that threat.

Now for the bad news: sheer irresponsibility may be a winning political strategy.

Mr. McCain’s claim that opponents of offshore drilling are responsible for high gas prices is ridiculous — and to their credit, major news organizations have pointed this out. Yet Mr. McCain’s gambit seems nonetheless to be working: public support for ending restrictions on drilling has risen sharply, with roughly half of voters saying that increased offshore drilling would reduce gas prices within a year.

Hence my concern: if a completely bogus claim that environmental protection is raising energy prices can get this much political traction, what are the chances of getting serious action against global warming? After all, a cap-and-trade system would in effect be a tax on carbon (though Mr. McCain apparently doesn’t know that), and really would raise energy prices.

The only way we’re going to get action, I’d suggest, is if those who stand in the way of action come to be perceived as not just wrong but immoral. Incidentally, that’s why I was disappointed with Barack Obama’s response to Mr. McCain’s energy posturing — that it was “the same old politics.” Mr. Obama was dismissive when he should have been outraged.

(emphasis added)

I think that Krugman has a legitimate concern about pandering to voters on energy prices, even as Krugman`s a bit too close to the political struggle to acknowledge that environmental policies of course affect energy prices, and that “sheer irresponsibility” has been a winning political strategy for as long as – well, for as long as there have been politicians.

As I have noted elsewhere, there is an extremely wide array of opinion that carbon taxes would be the most effective and least damaging approach, and, if rebated or applied to reduce taxes on income or labor, would find long-term political support, yet politicians refuse to mention them, but instead present us with monstrous giveaways like those included in the Warner-Lieberman bill (which McCain`s bill resembles).  Heck, even Exxon, AEI, RAND and the American Council for Capital Formation have come out in favor of carbon taxes! 

Krugman explores Weitzman a little more closely in a July 29 blog post at the New York Times.  That post, and the further discussions it links to, is well worth exploring.  However, one can see Krugman`s train of thought at the very end, where he asks:

The question is, can we mobilize people to make modest sacrifices to protect against low-probability catastrophes in the distant future?

He`s obviously decided over the past few days that the way to mobilize people is to let his dander fly.  While I believe that a little more sophistication is needed, I would note that Gene Callahan, at least, has argued that swinging a moral club is an appropriate weapon, even for libertarians.  I applaud Krugman for letting not only McCain but also Obama feeling some of his lash.

I note that there are some commentators already wringing their hands over Krugman`s moralizing, but they very curiously fail to comment on the very real rent-seeking (and climate risk-shifting) and PR manipulation by fossil fuel interests that lies at the core of the policy deadlock.

 

PS:  Some of my thoughts on the current policy deadlock are as follows:

– many fossil fuel firms want to be compensated – in the form of new pork for gigantic and iffy “clean coal” projects – for budging from their current free ride on our common atmosphere;

– fossil fuel interests, including their customer chain, have great political pull in both parties (for example, nobody is yet willing to let American car manufacturers suffer their deserved fate, and Byrd and Rockefeller have alotof pull);

– financial firms – other than insurers – all looking for a cap and trade scheme, so they can profit from carbon trading;

– many firms who see opportunities in new technologies are busy fighting for advantage in the draft legislation; 

– not least, politicans are looking for legislation that promises the greatest flow of pork and campaign contributions, and have little interest in being open or hoinest with taxpayers;

– Democrats have little stomach for leadership – at least until the American people finish hanging the Republican party over its disastrous foreign policy and obvious corruption;

– there are considerable opportunities for policies that improve our tax system and regulation of energy resources and infrastructure.  I look for Republicans to start offering them after they have completely squandered their turn at the wheel of state, and are locked again into minority status in Congress.

 

 

Jim Hansen warns of slow-motion disaster and welcomes future public trials of fossil fuel CEOs for buying government delay

June 27th, 2008 5 comments

Prominent climatologist Dr. James Hansen, Director of the NASA Goddard Institute for Space Studies and Adjunct Professor of Earth and Environmental Sciences at Columbia University, who has long been warning of the long-term consequences of man’s essentially uncontrolled experiment with the world’s climate through emissions of GHGs (CO, methane and CFCs), soot and agricultural practices, has recently ramped up his message that urgent action is needed in order to avoid triggering “dangerous” climate change in the form of rising temperatures and an irreversible melting of the Greenland and Antarctic ice caps. 

1.  Hansen has apparently decided that it is time to take the gloves off in a battle that he thinks requires government action, which action he views as having been delayed by fossil fuel firms that have benefitted from (and underwritten efforts to stall movement away from) the status quo.  Accordingly, in order to shift the political balance, Hansen has decided to call not merely for decreases in GHG emissions, but direct leverage against the fossil fuel companies (in an op-ed at the Huffington Post):

Special interests have blocked transition to our renewable energy future. Instead of moving heavily into renewable energies, fossil companies choose to spread doubt about global warming, as tobacco companies discredited the smoking-cancer link. Methods are sophisticated, including disguised funding to shape school textbook discussions.

CEOs of fossil energy companies know what they are doing and are aware of long-term consequences of continued business as usual. In my opinion, these CEOs should be tried for high crimes against humanity and nature. If their campaigns continue and “succeed” in confusing the public, I anticipate testifying against relevant CEOs in future public trials.

The fossil-industry maintains its stranglehold on Washington via demagoguery, using China and other developing nations as scapegoats to rationalize inaction. In fact, we produced most of the excess carbon in the air today, and it is to our advantage as a nation to move smartly in developing ways to reduce emissions. As with the ozone problem, developing countries can be allowed limited extra time to reduce emissions. They will cooperate: they have much to lose from climate change and much to gain from clean air and reduced dependence on fossil fuels.

(emphasis added)

Is this rhetoric appropriate?  Certainly not, even as the frustration that underlies it is an understandable manifestation of the frustration that is common (and perhaps unavoidable) in politicized fights over the use of government to satisfy one’s preferences over the preferences of others (viz., “rent-seeking”).  Granted, much is at stake (particularly if Hansen’s views of the risks are correct), and my sympathies are with Hansen (I am persuaded that his concerns have merit, and the rent-seeking by fossil fuel firms is undeniable), but such rhetoric is inappropriate as long as it is unsupported by allegations of actual criminal behavior – as opposed to simple frustration that the fossil fuel firms have been effective in lawfully manipulating the political system for their private gain. 

While a libertarian may sanction the use of moral suasion and opprobrium – even civil litigation – to strong-arm one’s opponents, calling for criminal sanctions by the state against those have successfully manipulated politicians and bureaucrats is a step that simply compounds the underlying illness of statist rent-seeking.

One suspects that Dr. Hansen is simply playing a public relations game, and is not serious about the “state trials”, as he has not called for the firms to be muzzled, but rather expressed his opinion and hope that they should some day be held to account for their actions.  Well, Dr. Hansen is certainly entitled to his opinion AND to castigate fossil fuel firms for behaviors that he objects to; while his rhetoric is disturbing, at least he’s only volunteering to be a witness and not prosecutor, judge and jury.

Sadly, differing preferences over how to use resources are inevitably politicized when there are no clear owners of such resources or ownership is socialized through government ownership or regulation.  The fossil fuel companies and their heavy users have clearly been rather adept at manipulating political levers up until now; whether Dr. Hansen’s effort to turn up the heat on them will be effective or simply provides them with more ammo remains to be seen.

2.  On another level, I do think that Hansen’s rhetoric on this is unfortunate, as it is likely to detract from his scientific message, which he elucidates very well in articles, presentations and scientific publications available at his Columbia U. webpage (linked above).  It also draws attention away from his specific policy positions, which have been critical of pork and bureaucratic management of the type presented by the Warner-Lieberman bill.   Hansen has recently expressed strong preference for a simple carbon tax that is fully rebated on a per capita basis, as further noted in the same op-ed (in which Hansen sounds very much like George Will, who also prefers a carbon tax over cap and trade):

Carbon tax on coal, oil and gas is simple, applied at the first point of sale or port of entry. The entire tax must be returned to the public, an equal amount to each adult, a half-share for children. This dividend can be deposited monthly in an individual’s bank account.

Carbon tax with 100 percent dividend is non-regressive. On the contrary, you can bet that low and middle income people will find ways to limit their carbon tax and come out ahead. Profligate energy users will have to pay for their excesses.

Demand for low-carbon high-efficiency products will spur innovation, making our products more competitive on international markets. Carbon emissions will plummet as energy efficiency and renewable energies grow rapidly. Black soot, mercury and other fossil fuel emissions will decline. A brighter, cleaner future, with energy independence, is possible.

Washington likes to spend our tax money line-by-line. Swarms of high-priced lobbyists in alligator shoes help Congress decide where to spend, and in turn the lobbyists’ clients provide “campaign” money.

Hansen’s “tax and 100% dividend” proposal, which he floated earlier this month, is based on Peter Barnes’s “Sky Trust” cap and dividend approach outlined in “Who Owns the Sky: Our Common Assets and the Future of Capitalism” (Island Press, Washington, D.C., 2001) and reviewed here.

3.  Libertarian legal scholar Jonathan Adler cited Hansen’s op-ed at the Volokh Conspiracy blog; I copy below a few comments that I noted in response:

Jon, first, let’s not forget that Hansen is specifically addressing not only oil cos but also the coal firms like Peabody and Massey – firms that are leaving massive messes because either they deal in publicly owned and bureaucratically administered land or because they’ve managed to capture the police, prosecutorial, judicial and political machinery where they operate, as well as the favor of the administration and federal regulators [see my blog post here].

Second, all of his words about public trials notwithstanding, Hansen is obviously waging battle in the courts of public opinion, which is obviously something he has every right to and, far from infringing libertarian principles, seems entirely consistent with them. As Gene Callahan has recently noted,

One way negative externalities can be addressed without turning to state coercion is public censure of individuals or groups widely perceived to be flouting core moral principles or trampling the common good, even if their actions are not technically illegal. Large, private companies and prominent, wealthy individuals are generally quite sensitive to public pressure campaigns.

After all, if libertarians had their way and government stepped out of the roads and regulatory businesses, it’s long been the libertarian position that private actions, including lawsuits against road owners, would lead to voluntary collective actions and large damage suits that would better manage resources by incentivizing reductions in pollution and other externalities. (In this context, there are, of course, private action suits now under way against the major fossil fuel firms for climate change damage; these face obvious hurdles, but a libertarian might wish for success, simply to breathe a little more life into common law remedies and take the pressure off of the demands for state action.)

Libertarians do not, as a matter of principle, object to informal public pressure. It is simply Hansen’s implication that criminal trials are more appropriate than the common law tort mechanism – which is sadly not too well known and admittedly rather withered due to the success in polluters in subverting injunctive remedies and in capturing the resulting regulatory process – that offends.

On the policy end, of course Hansen does have a statist proposal, but it is probably the cleanest one out there: the carbon tax and 100% rebate proposal, which would put all carbon tax revenues back in the pockets of Americans and than cut short alot of the rent-seeking and pork-management efforts now underway. That’s why George Will has recently concluded that a carbon tax is the best approach.

WHY Pat Michaels says "The Antarctic Ain’t Cooperating"

March 4th, 2008 2 comments

[Update:  I have separately posted for the interest of readers my exchange of emails with Chip Knappenberger, Pat Michael`s colleague at his self-described “advocacy science consulting firm”, New Hope Environmental Services.]


In comments on my preceding post, Antarctic cooling? Or WHY “The Antarctic Ain’t Cooperating”, Geoffrey Plauche pointed to an essay entitled “The Antarctic Ain’t Cooperating” at the “World Climate Report” – the website run by former climate scientist, now policy critic Pat Michaels.   Review of Michaels’ piece prompted further work, which I first posted as an update to my prior post.  Given the broader issues raised by that review, I have decided also to post it separately.

When I pointed out to Geoffrey that Michaels’ essay leaves out an awful lot, he replied that Michaels’ piece was clearly “criticizing … the alarmist hype coming from some scientists, some politicians and others (like Gore), and particularly the media”.  Thus I decided to spend a little more time exploring just what it was that Michaels was up to in his essay. 

While a review of the post certainly shows criticism of the press (not scientists) for incomplete disclosure and discussion of data about Antarctica (a criticism that is not in itself unfair), a little further digging reveals that it is Pat Michaels who is being deceptive – for self-acknowledged political and business reasons – by failing to refer to or provide additional background information (noted in my prior post and update) that show that there is plenty of evidence indicating that while Antarctica may be warming more slowly than elsewhere (which was not unexpected), there are ample signs of warming and other changes consistent with GHG forcings.  The Antarctic is already “cooperating” more than we need it to.

Pat Michaels describes the “World Climate Report” as “concise, hard-hitting and scientifically correct” and “exhaustively researched, impeccably referenced, and always timely”.   It is intended as a “response to the global change reports which gain attention in the literature and popular press” that “points out the weaknesses and outright fallacies in the science that is being touted as “proof” of disastrous warming” and is “the perfect antidote against those who argue for proposed changes to the Rio Climate Treaty, such as the Kyoto Protocol, which are aimed at limiting carbon emissions from the United States”.  Michaels trumpets World Climate Report as the “definitive and unimpeachable source for what Nature now calls the “mainstream skeptic” point of view, which is that climate change is a largely overblown issue ….”  http://www.worldclimatereport.com/index.php/about-us/

But who produces the World Climate Report?  Pat Michaels’ personal and self-described “advocacy science consulting firm”, New Hope Environmental Services.  And who hires Pat Michaels?  Well, firms that have a direct financial stake in trying to hang onto their present ability to emit GHGs free of charge into the global atmopsheric commons, of course, even though Pat does his best for his clients’ sake to keep it under his hat. ; http://notes.sej.org/sej/tipsheet.nsf/80c21fb7123767b586256cd0000f3f91/257E45ECA8C523648625735B007503C3?OpenDocument.

It is not surprising that particularly heavy users of the global commons (clearly electric utilities and coal producers in Pat’s case) would like to continue to operate under the same sweet terms that they have up until now, but other users of the global commons of course have the right to their own preferences as well.  But why the secrecy?  Why aren’t the electric utilities and coal producers who support Pat, instead of funding one-sided arguments about science, willing to be straightforward about their preferences so all commons users can discuss how to manage the atmospheric commons?  I suspect that it has something to do with the small problem called “rent-seeking” whenever governments are in the middle of a problem – viz., these fossil fuel interests are trying to influence government in order to get (manintain!) favorable treatment, as opposed to trying to come to terms with others.  Thus the desire to mask their behavior and muddy the science – to influence public opinion and government – rather than forthrightness.

In other words, at least at the World Climate Report, Pat Michaels is in the business of selling climate policy positions.  This is clearly manifested in posts like “The Antarctic Ain’t Cooperating”, which while “scientifically correct” is much less than scientifically complete, and misleadingly so.  This degree of disingenuousness shows that his motivation isn’t really so much to clarify as it is to muddle – in order to advance his own policy preferences and/or those of his clients.  While Pat and his clients are fully entitled to their own preferences, they are not entitled to their own facts.  If Pat wants to really advance our understanding of climate developments, he should be providing a rounder picture, rather than feeding factoids to those who are happy to pretend (or continue to fool themselves) that there is no scientific case for ongoing climate change (and a significant human role in it).

But as “skewed but technically accurate” science is what Pat’s clients want, it’s hard to fault him for doing his best to be responsive to them.  But it nevertheless behooves us to be aware, when Pat speaks, who has actually paid for his voice, and why, so we might better know how to weigh his words.  Otherwise we are simply allowing ourselves to be manipluated by others, others who are happy to play on the confirmation biases of readers who are predisposed to believe either that man is not influencing the climate or that it is not a “problem” that we should invite our governments to address.

I refer readers to my prior post (and update) to review additional information on what is happening in the Antarctic. 

Here’s to hoping for greater forthrightness, both on the science and on our respective preferences with respect to what is a shared – an indispensible – common resource.

I’ve decided to put up this little post in connection with Walter Block’s recent post,  http://blog.mises.org/archives/007828.asp, in order to avoid having my comment stuck in a spam filter (I’ve found that comments with too many links get caught).


I see I missed providing a cite to a recent article by Andew Revkin at the NYT on what scientists think of some of this winter’s screwy weather (the topice of Block’s post):

The IPCC’s 2001 report says: “For the change in annual mean surface air temperature in the various cases, the model experiments show the familiar pattern documented in the SAR with a maximum warming in the high latitudes of the Northern Hemisphere and a minimum in the Southern Ocean (due to ocean heat uptake).”

“Despite an overall global warming trend, temperatures over large parts in the interior of Antarctica have exhibited a small but distinct cooling trend during the past several decades. Thompson and Solomon (p. 895; see the news story by Kerr) present evidence that high-latitude Southern Hemisphere circulation changes during the past few decades reflect a systematic trend in regional atmospheric circulation. Trends in tropospheric circulation trends can be traced to the recent cooling of the lower stratosphere caused by photochemical ozone losses.”


Study Shows Potential for Antarctic Climate Change, Oct. 6, 2004:  http://www.giss.nasa.gov/research/news/20041006/



“Since the late 1960s, the SAM [Southern Annular Mode] has more and more favored its positive phase, leading to stronger westerly winds. These stronger westerly winds act as a kind of wall that isolates cold Antarctic air from warmer air in the lower latitudes, which leads to cooler temperatures.


“Greenhouse gases and ozone depletion both lower temperatures in the high latitude stratosphere. The cooling strengthens the stratospheric whirling of westerly winds, which in turn influences the westerly winds in the lower atmosphere. According to the study, greenhouse gases and ozone have contributed roughly equally in promoting a strong-wind, positive SAM phase in the troposphere, the lowest part of the atmosphere.”

UPDATE:


In comments below, Geoffrey Plauche points to a post entitled “The Antarctic Ain’t Cooperating” at the “World Climate Report” – the website run by former climate scientist, now policy critic Pat Michaels, as “criticizing … the alarmist hype coming from some scientists, some politicians and others (like Gore), and particularly the media”.  While a review of the post certainly shows criticism of the press (not scientists) for incomplete disclosure and discussion of data about Antarctica (a criticism that is not in itself unfair), a little further digging reveals that it is Pat Michaels who is being deceptive – for self-acknowledged political and business reasons – by failing to refer to or provide additional background information that show that there is plenty of evidence indicating that while Antarctica may be warming more slowly than elsewhere (which was not unexpected), there are ample signs of warming and other changes consistent with GHG forcings.


Pat Michaels describes the “World Climate Report” as “concise, hard-hitting and scientifically correct” and “exhaustively researched, impeccably referenced, and always timely”.   It is intended as a “response to the global change reports which gain attention in the literature and popular press” that “points out the weaknesses and outright fallacies in the science that is being touted as “proof” of disastrous warming” and is “the perfect antidote against those who argue for proposed changes to the Rio Climate Treaty, such as the Kyoto Protocol, which are aimed at limiting carbon emissions from the United States”.  Michaels trumpets World Climate Report as the “definitive and unimpeachable source for what Nature now calls the “mainstream skeptic” point of view, which is that climate change is a largely overblown issue ….”  http://www.worldclimatereport.com/index.php/about-us/


But who produces the World Climate Report?  Pat Michaels’ personal and self-described “advocacy science consulting firm”, New Hope Environmental Services. http://www.nhes.com/.  And who hires Pat Michaels?  Well, firms that have a direct financial stake in trying to hang onto their present ability to emit GHGs free of charge into the global atmopsheric commons, of course, even though Pat does his best for his clients’ sake to keep it under his hat. http://notes.sej.org/sej/tipsheet.nsf/80c21fb7123767b586256cd0000f3f91/257E45ECA8C523648625735B007503C3?OpenDocument; http://www.prwatch.org/node/5028  It is not surprising that particularly heavy users of the global commons (clearly electric utilities and coal producers in Pat’s case) would like to continue to operate under the same sweet terms that they have up until now, but other users of the global commons of course have the right to their own preferences as well.  But why the secrecy?  Why aren’t the electric utilities and coal producers who support Pat, instead of funding one-sided arguments about science, willing to be straightforward about their preferences so all commons users can discuss how to manage the atmospheric commons?  I suspect that it has something to do with the small problem called “rent-seeking” whenever governments are in the middle of a problem – viz., these fossil fuel interests are trying to influence government in order to get (manintain!) favorable treatment, as opposed to trying to come to terms with others.  Thus the desire to mask their behavior and muddy the science – to influence public opinion and government – rather than forthrightness. 


In other words, Pat Michaels is in the business of selling climate policy positions.  This is clearly manifested in posts like “The Antarctic Ain’t Cooperating”, which while “scientifically correct” is much less than scientifically complete, and misleadingly so.  This shows that his motivation isn’t really so much to clarify as it is to muddle – in order to advance his own policy preferences and/or those of his clients.  While Pat is fully entitled to his own preferences, he is not entitled to his own facts.  If Pat wants to really advance our understanding of climate developments, he should be providing a rounder picture, rather than feeding factoids to those who are happy to pretend (or continue to fool themselves) that there is no scientific case for ongoing climate change (and a significant human role in it).


But as “skewed but technically accurate” science is what Pat’s clients want, it’s hard to fault him for doing his best to be responsive to them.  But it nevertheless behooves us to be aware, when Pat speaks, who has actually paid for his voice, and why, so we might better know how to weigh his words.


Allow me to expand on the information I’ve already provided above by quoting relevant parts of two recent publications that provide a fuller picture of develoments in Antarctica:


1.    The British Antarctic Survey released in December 2007 a statement about climate change in Antarctica entitled “Climate Change – Our View”: http://www.antarctica.ac.uk/bas_research/our_views/climate_change.php.  Among others, the BAS statement concludes (with some rephrasing):




  • The Southern Ocean is a significant sink for both heat and carbon dioxide, acting as a buffer against human-induced climate change.



  • Since the commencement of continuous observations of Antarctic climate in1957-58, surface temperatures have remained fairly stable over much of Antarctica, although individual station records show a high level of year-to-year variability, which could mask any underlying long term-trend.



  • By contrast, large and statistically-significant warming trends are seen at stations in the Antarctic Peninsula. Over the past 50 years, the west coast of the Peninsula has been one of the most rapidly-warming parts of the planet. Here, annual mean temperatures have risen by nearly 3°C, with the largest warming occurring in the winter season. This is approximately 10 times the mean rate of global warming, as reported by the IPCC. The east coast of the Peninsula has warmed more slowly and here the largest warming has taken place in summer and autumn.



  • Significant warming has also been observed in the Southern Ocean. Upper ocean temperatures to the west of the Antarctic Peninsula have increased by over 1°C since 1955. Within the circumpolar Southern Ocean, it is now well-established that the waters of the Antarctic Circumpolar Current (ACC) are warming more rapidly than the global ocean as a whole. A comparison of temperature measurements from the 1990s with data from earlier decades shows a large-scale warming of around 0.2°C in the ACC waters at around 700-1100 m depth.



  • Analysis of weather balloon data collected over the past 30 years has shown that the Antarctic atmosphere has warmed below 8 km and cooled above this height. This pattern of warming in the troposphere and cooling in the stratosphere is seen globally and is the expected signature of increases in greenhouse gases, such as carbon dioxide. However, the 30-year warming at 5 km over the Antarctic during winter (0.75°C) is over three times the average rate of warming at this level for the globe as a whole.




  • Subtle but important changes have occurred in the atmospheric circulation around Antarctica. Since the early 1960s, atmospheric pressure has dropped over Antarctica and risen in the mid-latitudes of the Southern Hemisphere, a pattern of variability known as the Southern Hemisphere Annular Mode (SAM). These changes have resulted in a strengthening of the westerly winds that blow over the Southern Ocean around Antarctica. Stronger westerlies will impact on ocean currents, upwelling and mixing, but the consequences of such changes have yet to be fully understood.




  • Recent climate change has driven significant changes in the physical and living environment of the Antarctic. Environmental change is most apparent in the Antarctic Peninsula, where climate change has been largest. Adélie penguins, a species well adapted to sea ice conditions, have declined in numbers and been replaced by open-water species such as chinstrap penguins. Melting of perennial snow and ice covers has resulted in increased colonisation by plants. A long-term decline in the abundance of Antarctic krill in the SW Atlantic sector of the southern ocean may be associated with reduced sea ice cover.




  • Large changes have occurred in the ice cover of the Peninsula. Many glaciers have retreated and around 10 ice shelves that formerly fringed the Peninsula have been observed to retreat in recent years and some have collapsed completely. Furthermore, 87% of glaciers along the west coast of the AP have retreated in the last 50 years, and in the last 12 years most have accelerated. The Antarctic Peninsula is contributing to sea-level rise, at about the same rate as Alaska Glaciers.




  • Analysis of global measurements of atmospheric CO2 indicates that the Southern Ocean carbon sink has weakened significantly since 1981. This reduction in the capacity of the ocean to absorb CO2 has been attributed to increased upwelling of carbon-rich waters associated with strengthening of the westerly winds. Although future changes in the ability of the Southern Ocean to sequester CO2 are not completely known, this will be a key factor that helps shape global climate.




  • Most of the IPCC model experiments do simulate the observed strengthening of the circumpolar westerly winds, suggesting that this phenomenon is a robust response to changed climate forcing.




  • Further experiments have indicated that changes in anthropogenic forcings, particularly stratospheric ozone depletion and increases in greenhouse gases, have made the largest contribution to the strengthening of the westerlies. Recent climate observations show that changes in the strength of the westerlies strongly influence temperature variations on the east coast of the Antarctic Peninsula.




  • Taken together, these two results suggest that a significant fraction of the recent observed changes in climate in this part of the Antarctic can be attributed to human activity with a reasonable degree of certainty. Further support for this view comes from analysis of marine sediment records which enable us to examine how the extent of Antarctic Peninsula ice shelves has varied over time. While some of the smaller ice shelves in this region have periodically grown and decayed over the past 10000 years, the Larsen-B ice shelf appears to have been stable throughout this period until it collapsed suddenly in March 2002. This suggests that recent warm temperatures are exceptional within the context of the last 10000 years, making it unlikely that they can be explained by natural variability alone.




  • Many of the theories that seek to explain the circumpolar warming of the Antarctic Circumpolar Current also have the strengthening of the westerly winds as their root cause. Whilst there is not yet a clear consensus on which are the mechanisms that are most important, there is increasing evidence that a significant part of this change is ultimately driven by human activities.


 


2.  In May 2007, ENVIRONMENTAL RESEARCH LETTERS published “Scientific reticence and sea level rise” by James Hansen of the NASA Goddard Institute, http://www.iop.org/EJ/article/1748-9326/2/2/024002/erl7_2_024002.pdf?request-id=aLWrXm7q3BGdbL7j2wi7Kg, which discusses in part recent developments in the Antarctic:




  • Positive feedback from the loss of buttressing ice shelves is relevant to some Greenland ice streams, but the West Antarctic ice sheet, which rests on bedrock well below sea level, will be affected much more. The loss of ice shelves provides exit routes with reduced resistance for ice from further inland, as suggested by Mercer and earlier by Hughes.



  • Warming ocean waters are now thinning some West Antarctic ice shelves by several meters per year.



  • The Antarctic peninsula recently provided a laboratory to study feedback interactions, albeit for ice volumes less than those in the major ice sheets. Combined actions of surface melt and ice shelf thinning from below led to the sudden collapse of the Larsen B ice shelf, which was followed by the acceleration of glacial tributaries far inland. 



  • The summer warming and melt that preceded the ice shelf collapse was no more than the global warming expected this century under BAU scenarios, and only a fraction of expected West Antarctic warming with realistic polar amplification of global warming.



  • Modeling studies yield increased ocean heat uptake around West Antarctica and Greenland due to increasing
    human-made greenhouse gases.  Observations show a warming ocean around West Antarctica, ice shelves thinning several meters per year, and increased iceberg discharge



  • As the discharge of ice increases from a disintegrating ice sheet, as occurs with all deglaciations, regional cooling by the icebergs is significant, providing a substantial but temporary negative feedback. However, this cooling effect is limited on a global scale as shown by comparison with the planetary energy imbalance, which is now sufficient to melt ice equivalent to about one meter of sea level per decade.  Yet the planetary energy imbalance should not be thought of as a limit on the rate of ice melt, as increasing iceberg discharge yields both positive and negative feedbacks on planetary energy imbalance via ocean surface cooling and resulting changes of sea ice and cloud cover. 



  • Global warming should also increase snowfall accumulation rates in ice sheet interiors because of the higher moisture content of the warming atmosphere. Despite high variability on interannual and decadal timescales, and limited Antarctic warming to date, observations tend to support this expectation for both Greenland and Antarctica.  Indeed, some models have ice sheets growing overall with global warming, but those models do not include realistic processes of ice sheet disintegration.  Extensive paleoclimate data confirm the common sense expectation that the net effect is for ice sheets to shrink as the world warms. 



  • The most compelling data for the net change of ice sheets is provided by the gravity satellite mission GRACE, which shows that both Greenland and Antarctica are losing mass at substantial rates.  The most recent analyses of the satellite data confirm that Greenland and Antarctica are each losing mass at a rate of about 150 cubic kilometers per year, with the Antarctic mass loss primarily in West Antarctica. These rates of mass loss
    are at least a doubling of rates of several years earlier
    , and only a decade earlier these ice sheets were much closer to mass balance. 



  • Warming [in Antarctica] has been limited in recent decades, at least in part due to the effects of ozone depletion.  The fact that West Antarctica is losing mass at a significant rate suggests that the thinning ice shelves are already beginning to have an effect on ice discharge rates.  



  • Warming of the ocean surface around Antarctica is small compared with the rest of world, consistent with climate model simulations, but that limited warming is expected to increase.  The detection of recent, increasing summer surface melt on West Antarctica raises the danger that feedbacks among these processes could lead to nonlinear growth of ice discharge from Antarctica.
