"Omnibus perpensis, what’s the best way to provide energy for the globe’s 7.9 billion people?"

The short answer, for me, is to use/develop all sources of energy and to use the source(s) geographically most efficient for a given region (whose size and location are deliberately vague). And to use/develop those sources entirely absent government subsidy of any sort beyond funding privately done basic research in the development of new. (The topic of subsidies and credits is a separate, political economy matter.)

But it seems to me that a closely associated question also needs to be answered, and that is "Why do we care about atmospheric CO2 as a greenhouse gas in the first place?"

After all, the planet's recorded history (not the "recorded history" so conveniently referenced that begins so few years ago when industrial nations started keeping their records, of more or less accuracy) indicates, on the one hand from Greenland and Antarctica ice cores running back 400k years, that CO2 concentrations lag planetary warming.

On the other hand, records reaching back 10s of millions of years seem to contradict that by indicating utter lack of correlation between planetary temperatures and CO2 concentrations.

In the latter case, though, there seems to be a strong correlate: in both periods of higher temperatures than today and of much higher CO2 concentrations, life was lusher than today.

There's a second question that needs to be answered, too: "What is the relative impact, if any, of human activity on planetary warming and simple orbital and rotational mechanics?"

Summer in the northern hemisphere presently occurs when Earth is at its farthest from the sun in our non-circular orbit and when Earth is tilted away from the sun. That has implications for planetary temperature, and those implications are colored by ocean-land distribution. Over geologic time (which includes so far unpredictable continent movements), we'll get northern hemisphere summer when Earth is closest to the sun. Over much shorter times, we'll get summer when Earth is tilted toward the sun. The precession cycle is some 26,000 years, and we're (more or less) halfway through it. Also, continental drift won't enter into this cycle. Those two cycles harmonize, too, which further potentiates seasonal temperature highs and lows.

And: Earth is warming, in some part, because the sun has been heating up since it first lit off those 4.5, or so, billion years ago.

And then there's the more nearby temperature record. We may still be cooler than we were during the height of the Roman empire, although those records are incomplete and not planet-wide. We are still a bit cooler, 11,000 years after the last Ice Age, than the geologic warming trend line for Earth.

I'm having trouble seeing why we need to be so worried about CO2. I'm not having any trouble at all seeing the economic damage and associated destruction of lives (physical, emotional, economic) from trying to ban this or that energy source or mandating that or this source, or subsidizing one and punishing another.

Western Australia also gave us an object lesson in the outcome of entirely depending entirely on one, "renewable" energy source. That fiasco is an engineering problem, not a theoretical one, but the fix(es) are years, if not decades, away.

This series sounds really fantastic. Congratulations on recruiting such a distinguished group of authors to contribute.

I have two issues pertinent to this debate that I’m interested in hearing about.

(1) Is the science on climate change really as settled as the press and environmental activists claim it is?

Anyone who knows anything about science knows that things are rarely as “settled” as activists and pundits claim they are. It’s also a fact that the “scientific consensus” often proves to be wrong.

Just two recent examples from medicine prove the point. Since the mid 1970s the overwhelming consensus was that dietary cholesterol was implicated in increasing the risk for coronary artery disease. Massive changes in dietary recommendations were forcefully advocated and implemented. We now know that dietary cholesterol intake has little to nothing to do with LDL cholesterol levels or heart disease. The scientific consensus was massively wrong and the results were dire; a massive increase in obesity and an epidemic of Type II diabetes.

Want another example of the scientific consensus gone awry? There’s the idea that gastric ulcers were caused by diet. We now know that they are caused by bacteria.

Can we really be sure that the so-called consensus on climate change isn’t simply wrong or, more likely an exaggeration by the press, pundits and activists about whether that “consensus” is really definitive enough for the world to massively alter its economic relationships? What are the costs if the consensus is wrong or not quite the universal scientific agreement it’s cracked up to be. Who pays those costs?

(2) There are few if any costs to the intellectual elites associated to adjusting to climate change policies. Pundits, college professors, programmers, physicians, accountants, lawyers, government workers, etc. can obsess about climate change because the “fixes” hardly impact them at all. The working classes in the United States and elsewhere pay almost all of the costs. Massive job loss not only in the energy sector is but one example. What about the auto assembly line workers, gas station attendants, and garage mechanics who will lose their jobs because of electric cars?

What about the plumbers, roofers, landscapers and other contractors who have to bear the expense of trading in their pick-ups for expensive electric vehicles that they don’t want? What about the those same contractors who used to spend five minutes gassing up their vehicles who now have to spend 30 minutes charging up their vehicles? Of course they can charge up their vehicles at home; that is if they can afford several thousand dollars to install the home charging station.

It’s understandable that knowledge-elites don’t care. Many are commuting to their jobs on public transportation. Going forward, millions will be telecommuting and zooming. The changes required to ameliorate climate change won’t cost them anything.

Can climate change policies be implemented without causing calamitous economic ruin to working people around the world?

It’s hard to see how, but maybe the experts assembled by the leadership of the Cosmopolitan Globalists can explain how it might be accomplished.
