There was deep disappointment among political opponents of Florida Governor Ron DeSantis at their inability to pin blame on him for Hurricane Ian’s destruction. It was a terrible hurricane, but they so wanted it to be “Hurricane Hitler”, as Glenn Reynolds noted with tongue in cheek. That just didn’t work out for them, given DeSantis’ competent performance in marshaling resources for aid and cleanup from the storm. Their last ditch refuge was to condemn DeSantis for dismissing the connection they presume to exist between climate change and hurricane frequency and intensity. That criticism didn’t seem to stick, however, and it shouldn’t.

There is no linkage to climate change in actual data on tropical cyclones. It is a myth. Yes, models of hurricane activity have been constructed that embed assumptions leading to predictions of more hurricanes, and more intense hurricanes, as temperatures rise. But these are models constructed as simplified representations of hurricane development. The following quote from the climate modelers at the Geophysical Fluid Dynamics Laboratory (GFDL) (a division of the National Oceanic and Atmospheric Administration (NOAA)) is straightforward on this point (emphases are mine):

“Through research, GFDL scientists have concluded that it is premature to attribute past changes in hurricane activity to greenhouse warming, although simulated hurricanes tend to be more intense in a warmer climate. Other climate changes related to greenhouse warming, such as increases in vertical wind shear over the Caribbean, lead to fewer yet more intense hurricanes in the GFDL model projections for the late 21st century.

Models typically are said to be “calibrated” to historical data, but no one should take much comfort in that. As a long-time econometric modeler myself, I can say without reservation that such assurances are flimsy, especially with respect to “toy models” containing parameters that aren’t directly observable in the available data. In such a context, a modeler can take advantage of tremendous latitude in choosing parameters to include, sensitivities to assume for unknowns or unmeasured relationships, and historical samples for use in “calibration”. Sad to say, modelers can make these models do just about anything they want. The cautious approach to claims about model implications is a credit to GFDL.

Before I get to the evidence on hurricanes, it’s worth remembering that the entire edifice of climate alarmism relies not just on the temperature record, but on models based on other assumptions about the sensitivity of temperatures to CO2 concentration. The models relied upon to generate catastrophic warming assume very high sensitivity, and those models have a very poor track record of prediction. Estimates of sensitivity are highly uncertain, and this article cites research indicating that the IPCC’s assumptions about sensitivity are about 50% too high. And this article reviews recent findings that carbon sensitivity is even lower, about one-third of what many climate models assume. In addition, this research finds that sensitivities are nearly impossible to estimate from historical data with any precision because the record is plagued by different sources and types of atmospheric forcings, accompanying aerosol effects on climate, and differing half-lives of various greenhouse gases. If sensitivities are as low as discussed at the links above, it means that predictions of warming have been grossly exaggerated.

The evidence that hurricanes have become more frequent or severe, or that they now intensify more rapidly, is basically nonexistent. Ryan Maue and Roger Pielke Jr. of the University of Colorado have both researched hurricanes extensively for many years. They described their compilation of data on land-falling hurricanes in this Forbes piece in 2020. They point out that hurricane activity in older data is much more likely to be missing and undercounted, especially storms that never make landfall. That’s one of the reasons for the focus on landfalling hurricanes to begin with. With the advent of satellite data, storms are highly unlikely to be missed, but even landfalls have sometimes gone unreported historically. The farther back one goes, the less is known about the extent of hurricane activity, but Pielke and Maue feel that post-1970 data is fairly comprehensive.

The chart at the top of this post is a summery of the data that Pielke and Maue have compiled. There are no obvious trends in terms of the number of storms or their strength. The 1970s were quiet while the 90s were more turbulent. The absence of trends also characterizes NOAA’s data on U.S. landfalling hurricanes since 1851, as noted by Pail Driessen. Here is Driessen on Florida hurricane history:

“Using pressure, Ian was not the fourth-strongest hurricane in Florida history but the tenth. The strongest hurricane in U.S. history moved through the Florida Keys in 1935. Among other Florida hurricanes stronger than Ian was another Florida Keys storm in 1919. This was followed by the hurricanes in 1926 in Miami, the Palm Beach/Lake Okeechobee storm in 1928, the Keys in 1948, and Donna in 1960. We do not know how strong the hurricane in 1873 was, but it destroyed Punta Rassa with a 14-foot storm surge. Punta Rassa is located at the mouth of the river leading up to Ft. Myers, where Ian made landfall.”

Neil L. Frank, veteran meteorologist and former head of the National Hurricane Center, bemoans the changed conventions for assigning names to storms in the satellite era. A typical clash of warm and cold air will often produce thunderstorms and wind, but few of these types of systems were assigned names under older conventions. They are not typical of systems that usually produce tropical cyclones, although they can. Many of those kinds of storms are named today. Right or wrong, that gives the false impression of a trend in the number of named storms. Not only is it easier to identify storms today, given the advent of satellite data, but storms are assigned names more readily, even if they don’t strictly meet the definition of a tropical cyclone. It’s a wonder that certain policy advocates get away with saying the outcome of all this is a legitimate trend!

As Frank insists, there is no evidence of a trend toward more frequent and powerful hurricanes during the last several decades, and there is no evidence of rapid intensification. More importantly, there is no evidence that climate change is leading to more hurricane activity. It’s also worth noting that today we suffer far fewer casualties from hurricanes owing to much earlier warnings, better precautions, and better construction.

An Internet for Users, Not Gatekeepers and Monopolists

Factions comprising a majority of the public want to see SOMETHING done to curb the power of Big Tech, particularly Google/Alphabet, Facebook, Amazon, and Twitter. The apprehensions center around market power, censorship, and political influence, and many of us share all of those concerns. The solutions proposed thus far generally fall into the categories of antitrust action and legislative changes with the intent to protect free speech, but it is unlikely that anything meaningful will happen under the current administration. That would probably require an opposition super-majority in Congress. Meanwhile, some caution the problem is blown out of proportion and that we should not be too eager for government to intervene. 

Competition

There are problems with almost every possible avenue for reining in the tech oligopolies. From a libertarian perspective, the most ideal solution to all dimensions of this problem is organic market competition. Unfortunately, the task of getting competitive platforms off the ground seems almost insurmountable. In social media, the benefits to users of a large, incumbent network are nearly overwhelming. That’s well known to anyone who’s left Facebook and found how difficult it is to gain traction on other social media platforms. Hardly anyone you know is there!

Google is the dominant search engine by far, and the reasons are not quite as wholesome as the “don’t-be-evil” mantra goes. There are plenty of other search engines, but some are merely shells using Google’s engine in the background. Others have privacy advantages and perhaps more balanced search results than Google, but with relatively few users. Google’s array of complementary offerings, such as Google Maps, Street View, and Scholar, make it hard for users to get away from it entirely.

Amazon has been very successful in gaining retail market share over the years. It now accounts for an estimated 50% of retail e-commerce sales in the U.S., according to Statista. That’s hardly a monopoly, but Amazon’s scale and ubiquity in the online retail market creates massive advantages for buyers in terms of cost, convenience, and the scope of offerings. It creates advantages for online sellers as well, as long as Amazon itself doesn’t undercut them, which it is known to do. As a buyer, you almost have to be mad at them to bother with other online retail platforms or shopping direct. I’m mad, of course, but I STILL find myself buying through Amazon more often than I’d like. But yes, Amazon has competition.

Anti-Trust

Quillette favors antitrust action against Big Tech. Amazon and Alphabet are most often mentioned in the context of anti-competitive behavior, though the others are hardly free of complaints along those lines. Amazon routinely discriminates in favor of products in which it has a direct or indirect interest, and Google discriminates in favor of its own marketplace and has had several costly run-ins with EU antitrust enforcers. Small businesses are often cited as victims of Google’s cut-throat business tactics.

The Department of Justice filed suit against Google in October, 2020 for anti-competitive and exclusionary practices in the search and search advertising businesses. The main thrust of the charges are:

  • Exclusivity agreements prohibiting preinstallation of other search engines;
  • Tying arrangements forcing preinstallation of Google and no way to delete it;
  • Suppressing competition in advertising;

There are two other antitrust cases filed by state attorneys general against Google alleging monopolistic practices benefitting its own services at the expense of sellers in various lines of business. All of these cases, state and federal, are likely to drag on for years and the outcomes could take any number of forms: fines, structural separation of different parts of the business, and divestiture are all possibilities. Or perhaps nothing. But I suppose one can hope that the threat of anti-trust challenges, and of prolonged battles defending against such charges, will have a way of tempering anti-competitive tendencies, that is, apart from actual efficiency and good service.

These cases illustrate the fundamental tension between our desire for successful businesses to be rewarded and antitrust. As free market economists such as Murray Rothbard have said, there is something “arbitrary and capricious” about almost any anti-trust action. Legal thought on the matter has evolved to recognize that monopoly itself cannot be viewed as a crime, but the effort to monopolize might be. But as Rothbard asserted, claims along those lines tend to be rather arbitrary, and he was quite right to insist that the only true monopoly is one granted by government. In this case, many conservatives believe Section 230 of the Communications Decency Act of 1996 was the enabling legislation. But that is something anti-trust judgements cannot rectify.

Revoking Immunity

Section 230 gives internet service providers immunity against prosecution for any content posted by users on their platforms. While this provision is troublesome (see below), it is not at all clear why it might have encouraged monopolization, especially for web search services. At the time of the Act’s passage, Larry Page and Sergey Brin had barely begun work on Backrub, the forerunner to Google. Several other search engines had already existed and others have sprung up since then with varying degrees of success. Presumably, all of them have benefitted from Section 230 immunity, as have all social media platforms: not just Facebook, but Twitter, MeWe, Gab, Telegram, and others long forgotten, like MySpace.

Nevertheless, while private companies have free speech rights of their own, Section 230 confers undeserved protection against liability for the tech giants. That protection was predicated on the absence of editorial positioning and/or viewpoint curation of content posted by users. Instead, Section 230 often seems designed to put private companies in charge of censoring the kind of speech that government might like to censor. Outright repeal has been used as a threat against these companies, but what would it accomplish? The tech giants insist it would mean even more censorship, which is likely to be the result. 

Other Legislative Options

Other legislative solutions might hold the key to establishing true freedom of speech on the internet, a project that might have seemed pointless a decade ago. Justice Clarence Thomas’s concurring opinion in Biden v. Knight First Amendment Institute suggested the social media giants might be treated as common carriers or made accountable under laws on public accommodation. This seems reasonable in light of the strong network effects under which social media platforms operate as “public squares.” Common carrier law or a law designating a platform as a public accommodation would prohibit the platform from discriminating on the basis of speech.

I do not view such restrictions in the same light as so-called net neutrality, as some do. The latter requires carriers of data to treat all traffic equally in terms of priority and pricing of network resources, despite the out-sized demands created by some services. It is more of a resource allocation issue and not at all like managing traffic based on its political content.

The legislation contemplated by free speech activists with respect to big tech has to do with prohibiting viewpoint discrimination. That could be accomplished by laws asserting protections similar to those granted under the so-called Fairness Doctrine. As Daniel Oliver explains:

“A law prohibiting viewpoint discrimination (Missouri Senator Josh Hawley has introduced one such bill) would be just as constitutional as the Fairness Doctrine, an FCC policy which adjusted the overall balance of broadcast programming, or the Equal Time Rule, which first emerged in the Radio Act of 1927 and was established by the Communications Act of 1934. Under such a law, a plaintiff could sue for viewpoint discrimination. That plaintiff would be someone whose message had been suppressed by a tech company or whose account had been blocked or cancelled….”

Ron DeSantis just signed a new law giving the state of Florida or individuals the right to sue social media platforms for limiting, altering or deleting content posted by users, as well as daily fines for blocking candidates for political office. It will be interesting to see whether any other states pass similar legislation. However, the fines amount to a pittance for the tech giants, and the law will be challenged by those who say it compels speech by social media companies. That argument presupposes an implicit endorsement of all user content, which is absurd and flies in the face of the very immunity granted by Section 230. 

Justice Thomas went to pains to point out that when the government restricts a platform’s “right to exclude,” the accounts of public officials can more clearly be delineated as public forums. But in an act we wouldn’t wish to emulate, the government of Nigeria just shut down Twitter for blocking President Buhari’s tweet threatening force against rebels in one part of the country. Still, any law directly restricting a platform’s editorial discretion must be enforceable, whether that involves massive financial penalties for violations or some other form of discipline.

Private Action

There are private individuals who care enough about protecting speech online to do something about it. For example, these tech executives are fighting against internet censorship. You can also complain directly to the platforms when they censor content, and there are ways to react to censored posts by following prompts — tell them the information provided on their decision was NOT helpful and why. You can follow and support groups like the Media Research Center and its Censor Track service, or the Internet Accountability Project. Complain to your state and federal legislators about censorship and tell them what kind of changes you want to see. Finally, if you are serious about weakening the grip of the Big Tech, ditch them. Close your accounts on Facebook and Twitter. Stop using Google. Cancel your Prime membership. Join networks that are speech friendly and stick it out.

Individual action and a sense of perspective are what Katherine Mangu-Ward urges in this excellent piece:

“Ousted from Facebook and Twitter, Trump has set up his own site. This is a perfectly reasonable response to being banned—a solution that is available to virtually every American with access to the internet. In fact, for all the bellyaching over the difficulty of challenging Big Tech incumbents, the video-sharing app TikTok has gone from zero users to over a billion in the last five years. The live audio app Clubhouse is growing rapidly, with 10 million weekly active users, despite being invite-only and less than a year old. Meanwhile, Facebook’s daily active users declined in the last two quarters. And it’s worth keeping in mind that only 10 percent of adults are daily users of Twitter, hardly a chokehold on American public discourse.

Every single one of these sites is entirely or primarily free to use. Yes, they make money, sometimes lots of it. But the people who are absolutely furious about the service they are receiving are, by any definition, getting much more than they paid for. The results of a laissez-faire regime on the internet have been remarkable, a flowering of innovation and bountiful consumer surplus.”

Conclusion

The fight over censorship by Big Tech will continue, but legislation will almost certainly be confined to the state level in the short-term. It might be some time before federal law ever recognizes social media platforms as the public forums most users think they should be. Federal legislation might someday call for the wholesale elimination of Section 230 or an adjustment to its language. A more direct defense of First Amendment rights would be strict prohibitions of online censorship, but that won’t happen. Instead, the debate will become mired in controversy over appropriate versus inappropriate moderation, as Mangu-Ward alludes. Antitrust action should always be viewed with suspicion, though some argue that it is necessary to establish a more competitive environment, one in which free speech and fair search-engine treatment can flourish.

Organic competition is the best outcome of all, but users must be willing to vote with their digital feet, as it were, rejecting the large tech incumbents and trying new platforms. And when you do, try to bring your friends along with you!

It’s been said that many of the so-called “heroes” of the COVID pandemic who’ve been celebrated by the media are actually villains, and perhaps Governor Andrew Cuomo of New York should top the list. He saw to it that retirement homes were seeded with infected patients by ordering them returned their care homes rather than admitted to hospitals. Deaths in these facilities mounted, and they mounted faster than Cuomo’s administration was willing to admit. But the media and even Democrat state legislators have begun to take note, which is practically a miracle!

It seems equally true that some vilified by the media for their COVID response are actually heroes. Governor Ron DeSantis of Florida might deserve top honors here. Having spent the last month in Florida, I can attest that the business and social environment here is quite open compared to my home state (despite the presence of a few freaked out northerners who can’t quite fathom how stupid they look wearing masks on the beach). Florida’s infections, hospitalizations, and deaths have been lower than in California, New York, and many other states where lockdown measures have been stringent. (The first chart below is just a little busy…)

As I’ve written for much of the past year, COVID is far more dangerous to the elderly than anyone else, particularly those with co-morbidities. It’s also true that blacks (and some other minorities) are more vulnerable than whites, but if we want to save more black lives, we’re still better off prioritizing the elderly than racial groups. DeSantis understands this, and Florida is among the leaders in vaccinating the elderly population. (States don’t report this data on a uniform basis):

This approach to saving lives is obvious, yet critics at outlets like NBC News insist that DeSantis must be pandering to the senior population in Florida. Well, one wouldn’t want to be responsive to voters who happen to face high mortality risks, right? Others such as horror writer Stephen King have jumped onboard to offer their bumbling public health expertise as well.

There were many experts and the usual collection of numbskulls on social media who were wrong about Florida. DeSantis handled the pandemic as it should have been handled elsewhere. But the propaganda to the contrary goes unabated. For example, this article is pathetic. Can these people be serious? Or are they really that stupid? This goes for the Biden Administration as well, which had entertained the notion of imposing federal travel restrictions on Florida!

The political attacks on Florida and its governor reveal the extent to which opponents wish to ignore the evidence in plain sight. The data on COVID outcomes put the lie to the narrative of a public health emergency requiring massive restrictions on personal liberty. We know those policies are powerless to control the course of the contagion. The pandemic, however, was the key to convincing the public to accept a more authoritarian role for government. It’s a blessing that not everyone bought in, and that there are places like Florida where you can still go about your business in approximate normalcy.
