Xraymike79 doesn’t write very often anymore, but when he does it’s always worth your time because he’s one of the best, if not the best, big-picture chroniclers of human overshoot.
Here are a few excerpts from his latest essay but I recommend you read the whole thing:
“It may seem impossible to imagine that a technologically advanced society could choose, in essence, to destroy itself, but that is what we are now in the process of doing.” ~ Elizabeth Kolbert
Have things improved since I wrote my last essay a year ago for this blog? Have we miraculously transformed our entire energy system into one that does not poison and degrade the natural world? Have we slowed the onslaught of plastic pollution choking the planet’s rivers, lakes, and oceans? Have we done anything meaningful to halt the deterioration of the planet’s biodiversity toward mass extinction? Has this global, hi-tech civilization done anything significant to avert its own demise? Despite a constant flow of warnings from the scientific community and even a letter signed by more than 20,000 scientists, the simple answer is no. We have failed to address the complexity of our rising population and a degrading environment. Yes, we are self-conscious and thus able to recognize the fact that we are destroying the only home we have, but will the end result differ much from a population overshoot of bacteria in a Petri dish? Dependent on a continuous stream of finite resources imported from across the globe, modern megacities contain the seeds of their own destruction and that of all other life forms upon which humanity depends for its survival. The exponential growth of modern civilization ensures that one of the next doubling times will produce an absolute increase in overshoot that tips the world into unavoidable collapse. Enough damage may well have already been done; we’re just waiting for inertia to catch up to the impacts.
2017 set a global record for the most skyscrapers built in a single year and 2018 is predicted to eclipse it. The fossil fuel energy spent to construct those concrete and steel buildings translates into a melting cryosphere. Not to mention the fact that the carbon footprint of some of the world’s biggest cities is 60% bigger than previously estimated. “Renewable energy” still only comprises a tiny fraction of global energy consumption and plans for a total transition will take decades, if it’s even possible. Any growth in ‘renewable energy’ has been offset by increased consumption of fossil fuels in the developing world. 2017 marked a new record high in CO2 emissions with 2018 set to break that record. Global CO2 emissions have yet to peak, and the UN has warned that we are on course for a 3C world. It doesn’t help that the current U.S. administration plans to cut funding for alternative energy R&D, with the Energy Department expecting no drop in the U.S. carbon footprint through 2050. Having embedded itself in the U.S. government over a century ago, the fossil fuel industry has consistently worked to block climate change action and undermine environmental laws. A UK shipping executive recently admitted his industry is guilty of doing the same to protect their bottom line. The utilities companies knew the dangers as well. Like most corporations, the viability of their business model depends on perpetuating an unsustainable way of life. With warnings ignored since the late 1800s starting with the work of Svante Arrhenius, it should be obvious by now that intelligence without sapience has produced deadly results. A new study finds “the most accurate climate change models predict the most alarming consequences.” The recently released U.S. National Climate Assessment has similar findings:
While climate models incorporate important climate processes that can be well quantified, they do not include all of the processes that can contribute to feedbacks (Ch. 2), compound extreme events, and abrupt and/or irreversible changes. For this reason, future changes outside the range projected by climate models cannot be ruled out (very high confidence). Moreover, the systematic tendency of climate models to underestimate temperature change during warm paleoclimates suggests that climate models are more likely to underestimate than to overestimate the amount of long-term future change (medium confidence). (Ch. 15)
In a new ominous research finding, the evil twin of climate change(ocean acidification) is threatening the base of the marine food chain by disrupting the production of phytoplankton. This is yet another positive feedback loop increasing the rate of global warming. Climate feedback loops and ice sheet modeling are two weak areas of climate science, which means many unpleasant surprises. This is why researchers are constantly astonished. Adaptation is not a luxury most organisms have at the present rates of change. Techno-fixes are but a pipe dream.
Humans share two behavioral traits with all other species that are critically important to (un)sustainability. Numerous experiments show that unless or until constrained by negative feedback (e.g., disease, starvation, self-pollution) the populations of all species:
• Expand to occupy all accessible habitats.
• Use all available resources.
Like mindless bacteria bent on their own success, humans are victims of their own DNA and ingenuity. Any civilization that develops energy harvesting technologies allowing for rapid population growth will generate entropy which will in turn almost certainly have strong feedback effects on the planet’s habitability. Our exponentially growing economy is on a collision course with an immovable ecosphere.
The end of the world is coming for the naked ape, not by a cabal of bankers or any sort of cockamamie conspiracy tale like chemtrails, but by us –the entire human race– and the economic system we have developed. We have become hostages to complex structures, and ever more intricate specialization, to exploit diminishing resources. Pollution and waste are of little concern for capitalism until they become a significant drain on overall profitability and new frontiers to exploit are exhausted. When profitability on a global scale is finally threatened by climate change, it will be far too late. The response will be militarized and authoritarian.
The crisis of civilization is planet-wide this time. We’ve turned a utopian world of plenty into a dystopian world of fascist-leaning governments, industrial disasters, collapsing ecosystems, and technological addiction. We have a Commander in Chief who tweets bizarre debunked conspiracies at 3 am, gets his intel briefings from right-wing TV shows, dismantles any remaining hindrances to unbridled capitalism, and doesn’t know the difference between weather and climate. Public discourse has been dumbed down to the level of Fox news talking points and tribal groupthink. Those who can discern actual ‘fake news’ from scientific fact are left to watch in horror as mainstream scientific projections continue to prove overly optimistic. Not only are regulations being cut left and right, they are not being enforced. Government science advisors are being purged and replaced with mouthpieces for industrial polluters. In fact, this administrations is actively working to delegitimize and destroy government institutions. A sizable population of low information voters supports such actions, but it’s only to their own detriment. Of course, both major parties are under the sway of corporate power, but Trump and company represent an exceptionally predatory class of people. The Union of Concerned Scientists is monitoring the current administration’s war on science and public health; their latest report is here:
The administration’s one-year record shows an unprecedented level of stalled and disbanded scientific advisory committees, cancelled meetings, and dismissed experts. The consequences for the health and safety of millions of Americans could be profound.
We live in an age of unparalleled technological advancement, while at the same time we turn a blind eye to the disintegrating natural world that gave birth to us, having forgotten that our destiny lies in our relationship with the earth. Like Icarus who, in his exuberance, ignored his father’s warnings and flew too close to the sun, modern man with his technology has ascended to great heights without heeding sound advice.
“We’ve arranged a civilization in which most crucial elements profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster.” ~ Carl Sagan
