Near-term Habitat Loss for Humans by Guy McPherson

Fact: This planet has not harbored humans at 3.3 C or higher above baseline (i.e., the beginning of the industrial revolution). The number may be much lower. The jury is still out.

Fact: Humans are animals that depend on myriad other species for survival. As with all other animals, humans require clean air, potable water, healthy food, and the ability to maintain body temperature to sustain themselves.

Fact: Humans will die without a living planet that continuously supplies the elements listed above.

Fact: So far, all humans born into the physical realm have died. There is no rational basis for expecting any human to avoid this fate.

Fact: The Sixth Mass Extinction is under way.

Fact: All species have gone extinct or will go extinct. There is no rational basis for expecting Homo sapiens to avoid this fate.

Earth is officially at 0.85 C above baseline. The actual, unofficial global-average temperature is at least 0.1 C higher than the official figure. The ongoing El Niño will take Earth well beyond 1 C, the 1990 Rubicon from the United Nations Advisory Group on Greenhouse G.... As David Spratt points out in this video from October 2014, 0.5 C is was a more reasonable target. But those days are long behind us.

The rate of evolution via natural selection trails the rate of climate change by a factor of 10,000, according to a paper in the August 2013 issue of Ecology Letters. Clever as we are, we will not evade the Sixth Mass Extinction in the absence of myriad non-human organisms to supply the necessities of human life.

“Dramatic emission reductions (35%–80%) in anthropogenic aerosols and their precursors projected by Representative Concentration Pathway (RCP) 4.5 result in ~1 °C of additional warming,” according to an analysis published in the 20 May 2013 issue of Journal of Geophysical Research: Atmospheres. Instead of taking the cherry-picking, conservative approach assumed by academic scientists and the International Panel on Climate Change’s RCP, I’ll use the upper end of the conservative projection: Reducing industrial activity by 35% results in ~1 C global-average temperature rise, and eliminating global industrial activity results in an attendant ~3 C global-average temperature rise.

In other words, the absence of solar dimming associated with reflective particles could cause an abrupt rise in global-average temperature beyond that which has supported the existence of humans in the past (about 4 C, the number at which this headline from 2008 in The Guardianconservatively concludes human extinction). A large majority of the rise in temperature will come much more rapidly than the initial 0.85 C. Assuming the least-conservative end of the very conservative spectrum offered by the journal literature and the International Panel on Climate Change takes Earth well beyond the temperature at which human life has been harbored on this planet. Earth only gets hotter from there.

On the other hand, nobody knows the global-average temperature at which humans will become extinct. We’ve not yet completed this trial. By the time we complete the trial, there will be nobody left to record it. The lesson will come after the exam. 

The industrial economies of the world are inextricably linked. If Europe goes down the tubes because the derivatives bubble pops on that continent, then there will be consequences throughout the world. There’s a reason the Federal Reserve System of the United States gives money directly to foreign countries.

The rapid rise in global-average temperature I’ve described in this scenario occurs within days after collapse is complete. Sans methane and its exponential rise in Earth’s atmosphere. Sans 10-year “lag” in maximum heating from atmospheric carbon dioxide. Sans nuclear facilities melting down catastrophically.

I’m not suggesting all humans will die within days after the ongoing collapse of industrial civilization is complete. Rather, that process is likely to require months, or perhaps a few years. But it’s difficult for me to envision Earth with humans in 2030, notwithstanding the IPCC’s fantasy technology.

Contrary to conventional “wisdom,” we cannot sustain this unsustainable set of living arrangements indefinitely. Industrial civilization will end. Those of you believing somebody has the system under control are deluded. Nobody is in charge of the system. Only you are responsible for yourself. 

Shortly after civilization reaches its overdue end, habitat for humans will disappear. Between now then, every year will be worse than the one before, except for the few who benefit from oppression abroad, obedience at home, and destruction of the living planet. Obedience at home is exemplified by thoughtless people still on their hamster wheels.

Preppers take heart: Bunkers of beans will see you through a few years if you avoid fires, floods, superstorms, bitter cold, infectious diseases, and numerous other hazards. After that, it’s microbes and bacteria for ten million years or so, assuming humans become the first animals to persist beyond seven generations despite lethal mutations associated with bathing in ionizing radiation.

Everybody take heart: We get to live. It’s quite an amazing deal. Let’s get on with it.
