I always enjoy your writing, Geary. This one is a topic close to my heart. I've been reading the various IPCC summaries since before AR5, along with selected original academic research. A few years ago I was so perplexed by the mismatch between what the science actually says and what the media reports, that I set about reading the papers behind the headlines (in those cases where any were cited). The distortions are frightening. Some months ago the Guardian splashed a headline that 20 feet of short term sea level rise was all but guaranteed (which was nothing like what the background paper said). There are regular alarmist reports on the BBC and elsewhere about sea level rise when the subjects are actually coastal cities on the worlds major river deltas which are subsiding due to river culverting and unsustainable groundwater extraction.

The linkage of singular climatic events to climate change is likewise misleading in the extreme. In many cases, rates of burning, flooding, storms etc. are the same as historical norms. In ALL cases, the toll on human life is a tiny fraction of its historical impact, and that's even before allowing for population increases. Just look at the last thousand years of flooding in the North Sea basin. Regular concurrences of onshore winds, high tides, and low pressure systems have produced devastating storm surges with decadal frequency. The impacts on low-lying coasts are horrific -- up to a hundred thousand deaths from some single events, and an average of ten thousand deaths each decade. As you will know, the barriers in the Thames and Rhine estuaries and other coastal works have made this mostly a thing of the past since the last killer floods of 1953.

In short, the effects of climate change -- while significant and certainly not to be ignored -- will be best mitigated by affluent societies capable of responding appropriately. The very last thing we need is to be starved of the energy on which modernity utterly depends. The irony is that the technologies best suited to the task are with us now: natural gas as a transitional fuel and Gen III and IV nuclear in the long run. Unfortunately we risk being the victims of Green ideology which has favoured unsuitable and unworkable solutions. Countries like my own (Ireland) now face an energy crisis due to reliance on wind which has failed to produce the goods for much of this summer.

Yet we seem determined to double down, going from 40% of power from renewables to 70% by 2030. That means that wind will be expected to provide 95% of power much of the time, to hit a 70% average. It will also have to cope with increased demand from EVs and electric heating if the Greens get their way, and with the complete retirement of coal and oil-fired generators. Meanwhile all new offshore gas exploration has been banned, and the Greens have shot down a much needed LNG import terminal because of their antipathy towards US fracking. We are a high tech country, with data centres expected to consume over 25% of power by 2030. But we have now been told we face grid instability for the next five years because of lack of investment in baseload power. We are also reliant on gas and electricity interconnectors to the UK which is facing its own energy cliff.

Worst of all is that a significant segment of the population is convinced that the world will literally burst into flames in the foreseeable a future. Adults decide not to have children, and children suffer from debilitating anxiety, all because of a fabricated horror story that has been concocted by a media seeking to attract more eyeballs.

Scientists are not immune either. I have been reading academic papers for long enough to see that there have been inexplicably bad predictions even for short term change. One "Ehrlichian" prediction from 2009 was that West African crop yields would fall by 25% by 2020 due to seasonal shift in rainfall patterns and other effects. In fact, crop yields rose by around 15%. Especially in Africa, the potential for better land management to increase yields is enormous.

Another paper reported that 50% of the worlds grain belts would be affected by climate change by 2100. This was dutifully reported in the press as a loss of 50% of the worlds grain. Of course, the paper says nothing of the sort -- northward shifts of grain belts into the Canadian prairies and Siberian steppes could increase the worlds available arable land. Needless to say such changes could be disruptive, but they are not the civilisational catastrophes (let alone extinction level events) that are being touted.

As you pointed out, the economic impact of climate change is barely a rounding error compared to the growth in global GDP by 2100, as long as we don't shoot our own feet off. Again, this is all available in the IMF's own modelling from the last two years.

I wonder if a backlash from a duped public is overdue. I somehow doubt it. The man in the street is not going to suddenly start reading academic papers. And yet, the UK's recent energy concerns just in time for COP26 later this month seem like an interesting opportunity for a clash of ideas.

Yes, it always fascinates me that the climate alarmists prattle on and on about "denialism" and the imperative to "follow the science", but then the most generally-accepted, best-resourced "science", the IPCC reports, do not in any way justify the kinds of policies they propose.

“This is not to say the man-made climate change is not a serious problem, because it is- albeit a more long-term, rather than immediate, problem than most realise.”

I see no reason to concede this point. We have a poor understanding of the causes of changing climate patterns which predate the industrial revolution by centuries, if not millennia.

I agree with everything here, Geary. Very well said. Huge fan!

I do, however, have a question. What do you mean by this phrase…"capitalism does produce gross wealth inequalities."?

I am reading it as that you believe that the inequalities created by voluntary market exchanges is a bad thing. But is this really your view? If so, why?

My take on the issue is that inequality of wages, profits, wealth and so on are absolutely necessary for the market to signal and incentivize change (in behavior, products, labor, etc). Inequality is thus not a bug, but a feature, and a necessary one at that. When markets are combined with a modern state with social safety nets and redistributive features (something true in all developed nations), the extremes of poverty are corrected, and are done so by tapping into the wealth generating power of markets.

So, my question is this… is inequality generated by properly functioning markets really a gross problem?

Climate change is only one of the many problems we would need to deal with.

There's also mass life extinction, mass pollution of the air, water and soils, the coming energy crisis, etc. And we're going to have to deal with everything, at the same time. Which is why it seems impossible to do so.

Increased difficulty to access clean water, for drinkink and food production, the increase of droughts in many places such as the Mediterranean periphery will undoubtedly throw millions on the road for their survival. Crises will make countries more unstable, especially those which already don't enjoy full stability.

The destruction of forests all over the globe, in Amazonia, Africa, on Sumatra, Java, Borneo, etc will only make things worse.

When I heard that Elon Musk was offering a $100M prize to anyone who'd find the best carbon capture technology, I couldn't help but think that was the most stupid idea I had ever heard.

Techno-fascination leads intelligent people to completely lose track of reality.

The best CO2 capture technology already exists and always has, it's called trees and plants.

If he really wants to help, he should use his billions to buy all primal forests on the planet to put an absolute stop to deforestation, and buy back the land claimed for intensive farming, palm oil and soy growing to let the forests regenerate. But then that's a lot less "sexy" than connected toys and gadgets.

Something that the article does not take into account is that, considering that growth keeps on being our motivation and objective, if we postulate that in 20, 30, 40 years time, millions more human will have access to what the West has enjoyed in terms of goods, equipment, infrastructures, whether it being medical, educational, urban, etc and all the wealth and comfort that goes with it, where will we find the resources to make everything we need for an ever growing number of people living by Western standards ?

In 40, 400, or 4,000 years, the earths will still be 13,000km in diametre. All the resources we would need to sustain billions living like Americans or Europeans won't just magically appear, out of thin air, just because we need them.

I'd like to point out that I am not a "socialist", not by American standards in any way, and I am a fierce opponent to the whole woke madness engulfing the world right now.

Yet I think the limits imposed by physics should help us understand that capitalism as it is today cannot go on sustainably, whether we like it or not. We're in for a diet, either planned wisely, or forced upon us by the reality of physics.

I agree wholeheartedly. If we destroy the engine of technological progress, we won’t be able to use it to solve the very real challenges we need it to solve. And on the whole, technological trends are decidedly good for the environment. Look at dematerialization for instance.

I’ll have to check out the Honest Broker. I’m not familiar with his work.

Some humility, please, Mr. Johansen. There are some things that we humans cannot comprehend: climate change being one. There are simply too many variables, too many unknowns to make meaningful predictions hundreds of years into the future.

I have never quite understood the equation of socialism with environmental friendliness. Certainly capitalist greed produces some true horror stories but it also has the capacity to create some incredibly advanced sustainable exploitation mechanisms. Socialist systems offer no such advantage. I can only think that the constant propaganda 'socialism is modern therefore it is good' pulls the wool over peoples eyes most effectively. Perhaps abandoning the shibboleth that socialism is a modern system is the way forward.
