Dear Crispin et al,

Perhaps those somebodies at NASA who claim that acid rain is acidifying the
ocean - rather than reducing its alkalinity - were simply not paying
attention to their high school chemistry because they too were stoned to
appreciate the subtle difference between 'more acid' and 'less alkaline'.

But a rose by any name will smell as sweet .....so, what are the
predictable systemic consequences of an ocean that is becoming less
alkaline? Is something that humanity is doing causing coral to blanche and
die?  Are the exhalations and run offs of industrial civilization slowly
poisoning the oceans and turning it into an underwater desert?
Can you or anybody at NASA scientifically differentiate between the noise
of conflicting big data from the tiny signals of a world system under
duress and in danger of being destroyed by anthropogenic excesses?

I nearly flunked HS chemistry so please keep your answers as simple as
possible.

What environmental impacts do you think present day climate and oceanic
science tells us humanity needs to collectively manage better because there
is credible evidence that tiny human generated changes in atmospheric and
oceanic conditions have the potential to trigger a cascade of consequences
that - oh my God - could or predictably do lead to a collapse of the
world's environmental balances to the point where industrial civilization
as we know and love it becomes impossible to sustain for billions of
humanoids who all want to be affluent western style.

I remember reading an article from the 1970's written by John Todd, a
marine biologist, about Science for the People in which he recounted his
awakening to the potential threat of ecocide.  He had spent months getting
the plants, corals, fish, crustaceans, worms, and micro flora and fauna in
a salt water aquarium into a healthy and stable balance.  His wife casually
tossed a couple of his freshly dry cleaned jackets onto the back of a chair
beside the aquarium while he was working at Script Oceanic Institute.  The
corner of one sleeve of a sports jacket just barely touched the water.
 When John returned from work in the late afternoon he found everything in
his aquarium had died from the carbon tetrachloride cleaning agents used to
dry clean his coats. His life as a marine biologist was never the same
again because he realized from that moment onward that infinitesimally
small changes in oceanic conditions had the power to precipitate massive
diebacks affecting entire ecosystems.

He began to research what concentrations of carbon tetrachloride and other
organo-phosphates interfered with the health of a particular type of fish
he knew well and he discovered that their presence in concentrations too
dilute for him to measure (back in the early 1970's) interfered with the
mating rituals of this species.  Its presence made it impossible for the
species to reproduce and therefore threatened the survival of this fish
species.  In fact the inability of these fish to mate - the disruption of
their mating behavior -  was the only way he could measure the presence or
absence of toxic chemicals in concentrations too dilute for the science of
that time to measure, monitor and manage.
A series of powerful mystical awakenings like this one helped John and
several of his colleagues who later joined forces to found the New Alchemy
Institute at Woods Hole Massachusetts confront the limitations of science
and humanity's ability to control the partially understood consequences of
industrial civilization.  It was this realization that industrial man is in
the same predicament as the sorcerer's apprentice in Walt Disney's Fantasia
that eventually led to to the formation of the New Alchemy Institute. The
sorcerer's apprentice knows just enough to activate the boomsticks but not
enough to turn them off  or control a vast army of scientific automatons
each mindlessly serving the short run interests of their owners.

They began experimenting with what Todd and co. called Ark's that were
purpose built terrariums in which people, plants, animals could potentially
live together forever within a closed man made bio-shelter covered with a
tough sunlight transmitting and trapping membrane. Because these
bioshelters were separate from the external eco-system the idea was to use
them as temporary fallout shelters in the event of a massive collapse of
the world's environmental system.

Since the eco-spasm has only happened in slow motion and petit mal
disruptions along the the periphery of the Euro-American urban-industrial
empire, Todd changed his focus from the bioshelter as lifeboats for wannabe
Adams and Eves and began applying the genius of his Ark systems to
mediating the interface between energy generation, industrial production,
the waste streams produced by urban conglomerations, large scale commercial
agriculture, and nature. His ecologically efficient and nature protecting
alternative waste treatment and recycling systems are being accepted today
because they save money and simultaneously create urban environment that
people prefer to live in that also meet stringent environmental standards
and simultaneously promotes human and environmental health..

Crispin, check out John Todd's (a fellow Canadian) perspective on the fatal
consequences of a tiny amount of CCl4 in a salt water aquarium and perhaps
you will be willing to graciously allow more space for the precautionary
principle in your climate and ocean science.

In service,

Cecil Cook
