Real Danger: Natural Runaway Warming Triggered By Man-Made Warming

July 22, 2017

When one looks at climate change, one should not look back, and whine that there was always change, as silly deniers do. One should look forward, ponder how bad it’s going to get, all too soon, and see the necessity for a carbon tax (or, more exactly, set-up worldwide carbon cost compensation).

Yes, so far we have only seen directly-man-induced global warming: the CO2 percentage went from 280 parts per million until 410 ppm (In truth, 490 ppm, as I have long explained, and will, again, below). In any case, 280 ppm up to 410 ppm, that’s an increase of 130 ppm. 130/280 = 46%. if one supposes that the obstruction CO2 presents to infrared light is proportional to its presence, then the “forcing” of the greenhouse effect should have been augmented by 46%. 

Moreover, indeed, one has to add to this man-made gases which have a greenhouse effect up to 100,000 times greater than CO2. That means they capability to block infrared radiation, and so to confine heat in the lower atmosphere instead of letting it escape to the cosmos is 10,000 times greater than CO2. 

Talking only CO2, while forgetting CH4 and NO2, is unscientific. Not to say stupid and criminal. Criminal in the sense of ultimate mass destruction.

Those greenhouse contributions of NON-CO2 manmade greenhouse gases amount to 25% of the total anthropomorphic contribution. So the real CO2 equivalent ppm is 490 ppm, not 410 ppm. An augmentation of more than 61% since 1789 CE. (And even that is an underestimate: because it overestimates the NO2 contribution in 1789 CE, say. In 1789 CE, there already was man-made methane, CH4, in the air, from massive pastoralism in the last 7000 years (some think that prevented a glaciation!). However, in 1789 CE, there was no NO2 whatsoever: NO2 is created only at high temperature, say by a diesel engine, when gases get hot enough to burn nitrogen in the combustion chamber!).

This is not a music the blissfully ignorant commons want to listen to. But they should:

To put all of this in perspective, the genus Homo has not evolved under such circumstances. Antarctica ice cores, 800,000 years old, show a density of CO2 of only 185 ppm.

In any case, 490 ppm, guaranteed to be 500 ppm in CO2 equivalent is well above the point at which Antarctica loses, or gains, its beech forests. 500 ppm is well above the Antarctica equilibrium point. The melting of the West Antarctica ice shield is thus guaranteed. The serious scientific question is now whether West Antarctica will melt within decades, as I believe, or centuries. That incoming disaster was long obvious. Only at the Paris Climate Conference, the IPCC, the United Nations Panel in charge of studying climate change admitted that I was right, and they were wrong, the temperature rise should be limited to ONLY 1.5 Centigrade, not to two degrees Centigrades:

Unfortunately last year, in 2016, the rise was 1.2 C, that is 80% of the way up to 1.5C… 2017, so far, runs close behind.

Exponential rise now in evidence (at last)? Look at the last few years…

(It used to be that scientists well-financed by those who loved fossil fuels, and their admirers in academic management, including university boards, and fuel plutos addicted governments pretended that the stability of West Antarctica was guaranteed for 5,000 years. Serious scientific papers full of gravitas, ladies and gentlemen, used to pontificate that no ocean would seriously rise for 5,000 years. Just like that. After all, why not say whatever, like Valley Girls, since it kept them greedsters rich and esteemed by the best with power (aristo-crats)? Scientists used to believe in the stability of the Holy Trinity, after all…)

It is strongly scientifically suspected that the last time Earth had comparable levels of atmospheric carbon dioxide that we have today was at least three million years ago, during the mid-Pliocene (then of course there was no CH4 in level in level comparable to what we see today, as cattle was less abundant, thanks to all too many lions, and no NO2 whatsoever).

Back then, global average temperature was about 3.6–5.2°F (2–3°Centigrade) warmer than it is today. Ocean level was much higher, by about 15–25 meters. So this heat and this sea level rise are now unavoidable. Already.

Back then there were camels in the high Arctic, as far north as one can go without swimming: https://patriceayme.wordpress.com/2015/05/04/camels-in-the-highest-arctic-again-soon/

The global density of carbon dioxide increased rapidly in the past couple of years, thanks in part to a strong El Niño which, lasted around two years (that unusual situation is a consequence of the strong planetary warming). El Niño patterns generally shift the location of tropical rains, often leaving tropical forests dry, thus more susceptible to fires — fires that, in turn, release a lot of stored carbon into the atmosphere. But direct human activities — like the burning of fossil fuels for transportation or electricity, or the conversion of forests and grasslands into developed areas or farmland — have also contributed to the rise in atmospheric carbon dioxide at a rate never seen before.

Thus we see the real problem: manmade warming, from all these gases triggers supplementary effects which, by themselves, augment the warming. For example, the more ice and snow melts in the polar and mountainous areas, the more those areas absorb sunlight into the ground, augmenting the melting and warming, year around.

https://patriceayme.wordpress.com/2009/11/18/2-c-is-too-much/

Man-made warming, which has been just a bit more than linear, is in danger of waking up strong exponential warming driven by natural phenomena which human activity would have triggered.

Once those strong natural exponential have been triggered, the warming will be runaway, and out of human hands. The analogy is being in a very dry forest full of deliciously smelling plants waving happily in a very hot wind. If one light a match, it will contribute to the warming, but not that much. Drop the light on the ground, watch the bushes catches fire: at this point natural warming is launched. Soon the fire gets to the crowns of the trees, an unstoppable inferno arises.

Some deniers anxious to win their daily bread, will insinuate that I am claiming that Earth will turn into Venus, without proof. No, not quite. What I am saying is subtle, and it’s experimentally backed-up by what happened in the past.

First of all, we have seen it all before, indeed, during the Permian-Trias mass extinction, 252 million years ago (more on that some other day, when, like today, I am travelling, and I have time only for an obvious essay…). Secondly, the runaway effects on Earth tend to be strongly limited after a while: if it gets way too hot, for example, there will so many clouds, from the steaming oceans, that the ground will be in permanent darkness, and, thus will cool off.

Moreover, the cause of the problem, humanity, would have been put to death, humanely or not, so Earth will have just to wait a millennium or two before enough CO2 will have been recombined in volcanic, and other soil to be removed from the air.

The present rise in CO2, and the rises of temperature and ocean acidity it brings can only be transient, on geological time scale. But it will rush, quasi-instantaneously, on such a scale, to a new equilibrium.

The carbon intense countries are playing with fire. There is so much European countries can do: France is down to 5.1 ton of CO2 emission per capita per year (and much more drastic measures have been taken, such as making carbon burning cars unlawful). The USA, Canada, Australia are above 16 tons per capita, per year. They have to be persuaded to cease and desist. The rest of the world will follow.

Burning Trump himself,  for real or in effigy, may feel good, yet it is neither recommended, nor sufficient, helas…First of all, burning such a mass of decomposing carbohydrates would noticeably augment the CO2 level globally. Secondly, there has been enough words, and empty insults. It’s time for action.

The only really significant action is a global carbon tax. Even Trump, who globally ridiculed himself by rejecting the Paris Climate Accord, like a bloated brat having a fit, could regain some of his lost honor, if he blurted on the international scene, that he has understood only a carbon tax would work, and promote it.
