The Coming Scramble for Survival


Necessity is the midwife of devolution. Invention's mother is running out of resources, so she is reverting to the tried and tested. Her next brood will be a passel of low-tech survival tools. System design and implementation takes about a decade and that is about all the time we have before nature puts her foot down (if the rate of Arctic sea ice melt is a reliable leading indicator). The rate of ocean warming will increase promptly after the ice is gone. Coastal cities will experience a markedly more rapid increase in flooding events. It will finally become clear to the man on the street that we haven't done what it takes to turn the tide and cannot spend another decade working on it. The new systems that we could have had ready to withdraw CO2 from the atmosphere will not be available in sufficient quantities to prevent a great die-off. Suffering will move people to act individually and locally and one of the only negative CO2 tools available to the average Joe will be the biochar that they can make on their own. Enduring the diminished resource future will, however, carry the built-in solution of doing less of what has long been damaging the climate. 
Below, a list from Drawdown.org shows 71 solutions before it gets to biochar, about one-third of which are scalable to the human individual level. Collective activity won't entirely cease and the ultra-wealthy will still be able to command some sizeable projects, but beyond what takes place in the next few years, there won't be much civic initiative to avoid the continuation of today's burgeoning apocalyptic chain-of-events. Debt levels keep rising and all it will take is a crisis for everything to collapse in a way that will take a century or more to heal. Some places "get it" more than others, though, so living in a state governed by the cognoscenti may allow some of today's heroes to continue a more efficacious collective fight against global warming into the next saeculum. If so, a few people may survive to perpetuate the human species.

Buying Time

When you hear the name, "Doomsday Clock," of the gauge used by the Bulletin of the Atomic Scientists to warn that the end is nigh, it leads you to think that these scientists are doomers. Scientists are actually some of the most optimistic people. The Scientists are using the clock to show how modern civilization is flirting with widespread disaster and permanent collapse. The latest developments put our risk as high as it has ever been.

What the doomsday clock is purporting to show is that we are not doomed (yet). Were the clock to ever reach midnight, we would be. The clock currently tells us that we are nearing the brink, but climate change can still be reversed in time and  nations can still control the nuclear genie. James Anderson, a professor of atmospheric chemistry at Harvard who earned his stripes by pointing out how chlorofluorocarbons were depleting the ozone layer, tells us that there is much less time than we would like to believe.

According to Anderson, the Arctic ice cap is on pace to melt entirely by 2023. When that goes, the permafrost will melt, a tipping point which is not included in IPCC models. As the Greenland ice sheet slides into the ocean, sea level rises 23 feet. Anderson maintains that stopping greenhouse gas emissions is not by itself enough to prevent these near-term changes to Earth's systems. He calls for an all out effort to direct resources toward drawing down atmospheric carbon with some added geoengineering in the form of deflecting sunlight from the poles.

Let governments and institutions do what they will. I doubt they will transform industry as quickly as Professor Anderson says is needed. For those of my generation who are retired, who are not involved in the major muscle movements to end fossil fuel use and draw down carbon, I encourage you to learn how to make and use biochar. It's catching fire around the world and may be one thing that buys the world more time to realize its predicament and make decisions that will allow humankind to continue to dwell upon the earth.

Do and/or Die

Peter Wadhams has ample reason to believe that when a truck ran him off the road, it wasn't just an accident. The Cambridge professor is a recognized and outspoken Arctic sea ice expert who is calling for a dramatic curtailment in fossil fuel use, lest the arctic meltdown shift into a cataclysmic series of positive feedback loops. At one point, the professor speculated that oil industry or government agencies had hired the driver to kill him, just as three other sea ice scientists encountered suspicious demises in the past few years. Causes of their untimely deaths were ascribed to falling down stairs, lightning, and vehicular collision while biking.

Death threats and assassination are nothing new to climate and environmental activists. The least you can do when so threatened is to put it on record, prompting an investigation if you are killed. Professor Michael E. Mann, famous for the hockey-stick graph of global temperatures, recently leveraged his potential martyrdom in a push back against the rhetorical garbage that continually belches from Trump's craw. 

In August 2016, Dr. Wadhams sealed his testimony about our predicament in the form of a book titled, A Farewell to Ice, fortuitously published a few months before the canary in the Arctic began to swoon with temperatures now 50 degrees Fahrenheit above normal, high enough to melt ice in Winter. Wadhams sees 2017 as the first likely summer without a polar ice cap, which would remove the reflecting shield from the Arctic, causing more warming, which would allow undersea permafrost beds to disgorge greater amounts of methane stored there. He has identified ten positive feedback loops associated with Arctic warming.


Hope, nonetheless, springs eternal and Wadhams puts his hope in a radical shift away from fossil fuels and a Manhattan project scale effort to draw down atmospheric carbon. If we don't carry out this change before 2035, Wadhams fears it will be too late. Leaving out the geoengineering piece, the Green New Deal offered by the Green Party could bring the U.S. to 100% fossil-free energy by 2030. If Wadhams is right, there is little room for letting this timeline slip. Either we change our way of living, or our world will change intolerably. Or, maybe we will die from unnatural causes before that, because we were bold enough to point out the problem.
