The Vacuity of Climate Science

cafeamericainmag.com

There has been a lot of CW discussion on climate change. This is an article written by someone that used to strongly believe in anthropogenic global warming and then looked at all the evidence before arriving at a different conclusion. The articles goes through what they did.

I thought a top-level submission would be more interesting as climate change is such a hot button topic and it would be good to have a top-level spot to discuss it for now. I have informed the author of this submission; they said they will drop by and engage with the comments here!

I think a more compelling argument might be "back in the 1970s the Science said that we were heading for an Ice Age due to industrial pollution and emissions - plus they've been predicting catastrophic climate change (melting of the ice caps, massive temperature changes and disruption) by 2000, 2010 and 2020 so they clearly don't know what they're doing'. We don't need to get bogged down in whether the greenhouse effect works as stated.

I'm not sure why that should be compelling at all. "Science" isn't just one coherent entity where one scientist being wrong makes all of the rest in the vaguely same sector fundamentally wrong. One scientist, who might as well not even be alive any more, making a prediction in 1967 has no bearing on scientists making predictions right now. Much of the list isn't even concerned with scientists - neither Al Gore or Prince Charles are such - or is related to issues other than climate change, such as peak oil, which has plenty of advocates as a theory who don't consider climate change to be all that dangerous (Greer, say).

"Wow! Look at all these failed AI predictions!" is a lackluster argument in debates about when the AGI is coming, if it is at all, and this is similarly a lackluster argument in climate debates.

With AI narratives they can point to trends and those trends are undeniably real! Nobody said 'oh AGI is impossible because the number of transistors on a chip is decreasing, we're actually heading for artificial stupidity', that would be silly. Furthermore, AI development is fundamentally unpredictable, people talk about probabilities of developing certain technologies by certain times.

Climate change is supposed to be a clear physical-material trend, yet there's been confusion about which direction it's moving and what consequences there might be and when they arrive. If they could get it wrong in the 1960s, 1970s, 1980s, 1990s and 2000s they can get it wrong today. The Pentagon report for instance:

https://www.theguardian.com/environment/2004/feb/22/usnews.theobserver

A secret report, suppressed by US defence chiefs and obtained by The Observer, warns that major European cities will be sunk beneath rising seas as Britain is plunged into a ‘Siberian’ climate by 2020. Nuclear conflict, mega-droughts, famine and widespread rioting will erupt across the world.

The document predicts that abrupt climate change could bring the planet to the edge of anarchy as countries develop a nuclear threat to defend and secure dwindling food, water and energy supplies. The threat to global stability vastly eclipses that of terrorism, say the few experts privy to its contents.

Among those scientists present at the White House talks were Professor John Schellnhuber, former chief environmental adviser to the German government and head of the UK’s leading group of climate scientists at the Tyndall Centre for Climate Change Research. He said that the Pentagon’s internal fears should prove the ‘tipping point’ in persuading Bush to accept climatic change.

Bob Watson, chief scientist for the World Bank and former chair of the Intergovernmental Panel on Climate Change, added that the Pentagon’s dire warnings could no longer be ignored.

Randall added that it was already possibly too late to prevent a disaster happening. ‘We don’t know exactly where we are in the process. It could start tomorrow and we would not know for another five years,’ he said. ‘The consequences for some nations of the climate change are unbelievable. It seems obvious that cutting the use of fossil fuels would be worthwhile.’

These weren't no-names or non-scientists but they were seriously and embarrassingly wrong. Imagine if we actually listened to these people, speedily cut fossil fuels out of the world economy accepting the energy rationing, economic mobilization and famines that would likely happen... only for it to be a nothingburger.

In AI there are clear achievements and errors on both sides - some people said we'd get self-driving vehicles by 2000, others by 2030, others never. Well, we have self-driving cars today. We have GPT-4. Things the AI alarmists foresaw actually showed up, perhaps not on time but they did arrive!

These weren't no-names or non-scientists but they were seriously and embarrassingly wrong. Imagine if we actually listened to these people, speedily cut fossil fuels out of the world economy accepting the energy rationing, economic mobilization and famines that would likely happen... only for it to be a nothingburger.

No they weren't, The Guardian just made that up. It's not a prediction, it's a brief outline of a hypothetical written by two non-scientists (both self-professed futurists working for the consulting firm Global Business Network) who specifically state that it is extreme and unlikely. The point is not that they think it is likely to happen, but that they think such unlikely but extreme scenarios should be considered and prepared for by the Pentagon.

An Abrupt Climate Change Scenario and Its Implications for United States National Security

We have created a climate change scenario that although not the most likely, is plausible, and would challenge United States national security in ways that should be considered immediately.

These are the steps they propose be taken:

  • Improve predictive climate models to allow investigation of a wider range of scenarios and to anticipate how and where changes could occur
  • Assemble comprehensive predictive models of the potential impacts of abrupt climate change to improve projections of how climate could influence food, water, and energy
  • Create vulnerability metrics to anticipate which countries are most vulnerable to climate change and therefore, could contribute materially to an increasingly disorderly and potentially violent world.
  • Identify no-regrets strategies such as enhancing capabilities for water management
  • Rehearse adaptive responses
  • Explore local implications
  • Explore geo-engineering options that control the climate.

Notice that reducing CO2 emisssions isn't even mentioned because their scenario is so abrupt that it would be too late, rather they are talking about preparing ways to mitigate the damage and/or do emergency geo-engineering, in case an unlikely scenario like that happens.

This report suggests that, because of the potentially dire consequences, the risk of abrupt climate change, although uncertain and quite possibly small, should be elevated beyond a scientific debate to a U.S. national security concern.

Among those scientists present at the White House talks were Professor John Schellnhuber, former chief environmental adviser to the German government and head of the UK’s leading group of climate scientists at the Tyndall Centre for Climate Change Research. He said that the Pentagon’s internal fears should prove the ‘tipping point’ in persuading Bush to accept climatic change.

Bob Watson, chief scientist for the World Bank and former chair of the Intergovernmental Panel on Climate Change, added that the Pentagon’s dire warnings could no longer be ignored.

So scientists find a speculative report by non-scientists and trumpet it as 'this is why you should reduce Co2 emissions'. It's just like the IPCC reports. They're tremendously dull documents that say things like 'high confidence that water stress will moderately increase in the medium term' and don't mention any existential threat except to Pacific islands. Meanwhile Extinction Rebellion is screeching about the apocalypse. Meanwhile governments are signing legal targets that commit them to deindustrialization and high energy costs, shutting down farms and so on.

There's a gap between what actual scientists are saying and what the message flowing through to policymakers, celebrities, media and the public is. Rather like COVID, the real science on mass-scale mask use was mixed and unclear, yet the Science mandated them.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.
