Climate Change Doesn’t Care What You Think About It
Early in my investment career a senior colleague said to me, “Stocks don’t care what you think about them,” meaning that my opinion on a stock had no bearing on how it was going to behave. That was an extremely valuable insight because all too often individuals think that their opinions influence real-world outcomes, leading to very serious mistakes.1
Climate change is the same. What individuals think about it is not going to change the fact that we can observe, in real time, that climate change has real world consequences.

Let’s start with the influence of climate change on near-term weather. Scientists are debating whether the warming of the oceans and other phenomena are increasing the number and frequency of hurricanes, tornadoes, fires, and other natural disasters. We may or may not be able to tease out a scientific model that proves a connection with absolute certainty.
Markets Don’t Care What You Think About Climate Change
But the markets don’t care whether we can build a model or not, what we can observe is that there has been a building boom in Florida’s coastal areas, that hurricanes have caused hundreds of billions of dollars of damage, and that homeowner insurance is hard to get and much more expensive than the rest of the country.
Florida homeowners face serious obstacles when it comes to homeowners insurance. Many insurers have reduced their presence in Florida through non-renewals and limited writing of new business.
In addition, 16 companies have voluntarily withdrawn from the state, including AAA, Bankers Insurance, Centauri Insurance, and Lexington Insurance. A further 16 insurers have gone insolvent since 2017. Still, other companies like Liberty Mutual haven’t responded to quote requests for Florida ZIP codes, and Farmers Group has stopped writing new policies statewide.
All this market volatility has left homeowners saddled with higher costs and a tough time finding the coverage they need.
Proprietary data from Insurify reveals that Florida homeowners already pay an average annual insurance premium of $11,759 per year. This is the highest of any state, and rates are likely to rise even more next year.”2
Insurance Markets Don’t Care What You Think About Climate Change
The insurance markets don’t care whether anyone thinks climate change is real or not, whether the Florida home insurance market is flawed, or whether it was bad planning to build on barrier islands. All it knows is that hurricanes have increased in frequency and power and that the losses sustained require much higher insurance rates. Or not quoting rates at all.
The energy markets don’t care whether anyone really believes that wind turbines kill birds and whales, cause cancer, or any other unconventional ideas. All it knows is that the wind blows hard in Texas, a major oil producing state, and that wind turbines are very profitable.
The Texas Comptroller of Public Accounts3 notes that Texas is a 17-year leader in US wind energy production, accounting for more than a quarter of all US wind energy, more than 40 MW of production, and 25,000 jobs that pay more than $100,000 a year. Some 28% of all electricity in Texas is generated by wind, and its marginal cost is often the lowest in the state.
Climate change doesn’t care whether or not people prefer internal combustion cars over electric vehicles (EVs). What we observe is that EVs are now about 9% of the auto market (up from 5% in 2022) and that EVs and hybrids together are now about 30% of the auto market.4
As unit prices drop, batteries become cheaper, and charging infrastructure grows, the percentage of EVs will rise. The market doesn’t care if anyone objects to the rise of EVs or that the trend can be marginally influenced by incentives. Objecting to horseless carriages as devil wagons[4] did not work. Just like early EVs, the first autos were curiosities owned by wealthy eccentrics. It took a while for them to become ubiquitous, but the trend was irreversible because they were cheaper, better, and faster than horse-drawn carriages.

What is the lesson in all this? That the markets, the real world, and the economy do not care if anyone believes in climate change or not. There are direct consequences of climate change, many of which we aren’t yet able to observe, but the real-world is already adapting and changing because of the immediate consequences of climate change.
Climate activists can stop worrying about people who don’t believe in climate change. They can stop worrying because climate change doesn’t care what anyone thinks.

While I like the general thrust of the argument, I would suggest it is mis-specified. To be clear, NOBODY denies that the Climate is changing, the term Denier is simply the catch-all Ad Hom as part of a full litany of logical fallacies designed to block discussion on Policies supposedly justified by ‘addressing Climate Change’.
Man made Global Warming is simply an hypothesis to explain Climate change, but has been inverted such that evidence of Climate Change is now cited as proof of the hypothesis.
No other theories are allowed and thus we have false dichotomies, slippery slopes, straw men attacks, red herrings, appeals to authority, appeals to emotion and every other rhetorical trick up to and including the inversion of the burden of proof.
Cunningly, the Green Industrial blob has got us ‘thinking past the sale’, any opponent to the man made Co2 argument now has to prove an alternative hypothesis, otherwise the AGW is (somehow by definition) deemed to be ‘true’. This is not science, nor logic, it is a bandwagon and markets are very, very, good at these.
‘The market’ sees capital being (mis)allocated to the Green Industrial Complex and ‘follows the money’ – including setting up large sustainability and climate change departments in Universities and Investment Banks. In that sense it doesn’t care about your or my opinion, but it does care about that of those directing those flows. If those change, then the market does.
I am not writing this with the benefit of Trump 2.0 hindsight, but watch how quickly the ‘market opinion’ has shifted.
