Harvard scientists are preparing to launch a geoengineering
experiment they hope will lead to lowering the Earth’s temperature, according
to the journal Nature. They are
proposing to spray calcium carbonate particles into the stratosphere which,
theoretically, could subsequently cool the planet by reflecting some of the
sun’s rays back into space. Where they belong, dammit!
The
gambit has been branded “The Stratospheric Controlled Perturbation Experiment.”
Scientists derived the idea for the SCPE in analyzing the results of the Mount
Pinatubo eruption of 1991, which injected an estimated 20 million metric tons
of sulfur of sulfur dioxide into the stratosphere, cooling Earth by 0.5 degrees
Celsius. Nature reports that the
planet’s average temperature returned to pre-steam engine levels for about 18
months as a result of the catastrophe, which killed approximately 800 people.
(“Pre-steam engine levels” is kind of a broad date range, covering as it does
everything from the “Big Bang” until the 1700s).
The experiment’s
first phase could launch as early as the
spring of this year, the journal stated, while pointing out that it
could backfire and disadvantage some areas of the world by robbing
crops of rain or shifting rain patterns. It could even alter the jet stream. Oh
well. You win some, you lose some, I guess. Better luck next time, Europe!
Nature states that “many researchers
have come to the alarming conclusion that the only way to prevent the severe
impacts of global warming will be either to suck massive amounts of carbon
dioxide out of the atmosphere or to cool the planet artificially. Or, perhaps
more likely, both.”
For
example, David Fahey, a scientist at the National Oceanic and Atmospheric
Administration, remarked to the journal: “Not talking about geoengineering is
the greatest mistake we can make right now.” I beg to differ. Carelessly screwing
with the planet is. Mad-scientist Fahey thinks mankind screwed up by
accidentally causing global warming, but that we have no choice but to take a
few shots in the dark to try to cool the planet down? What could go wrong?
Quite a
lot, actually. First off, we have no clue what injecting calcium carbonate
particles into the stratosphere would do, as, unlike “greenhouse gases,” the
substance doesn’t naturally or currently exist there. But shoot, what’s the
worst that could happen?
Popular Mechanics said of the
experiment, “chances are, that even with more accurate data the simulations
will tell scientists what many of them already suspect: altering the earth’s
climate is risky and carries a lot of side effects. More research and better
simulations might let us find less dangerous ways to dim the sun, but any such
experiment will always have a chance of making things worse.” Swell.
Jim
Thomas, co-executive director of the ETC Group, an environmental advocacy
organization that opposes geoengineering, had the most accurate take on the proposed
perturbation experiment. He told the journal: This is as much an experiment in
changing social norms and crossing a line as it is a science experiment.”
Indeed.
How did
the sun, of all things, suddenly get a bad rap? Why do we want to damn and dim
it? Isn’t it, along with water, the only reason we have been privileged to live
here? And who decides what temperature is j-u-s-t
right? Who gets to control the planet’s thermostat? What if Icelanders,
Scandinavians and Canucks want it set at 55 degrees Fahrenheit and those around
the equator want it at a constant 88 degrees? Do they go to war?
What
other great ideas are our best and brightest entertaining that might screw
up the Earth cool the Earth? Painting every square foot of the planet’s
landmass white to reflect as much sunlight as possible? Beaming the stiff,
lifeless images of Senators Schumer and Pelosi into the sky?
The
potential risk-reward ratio is completely askew here. It is mindful of a
pharmaceutical commercial for a, say, toenail fungus drug. Yes, after using
this drug you may have significantly nicer looking toenails (yay!), but it
could cause uncontrolled flatulence, migraine headaches, continual diarrhea,
arrythmia, suicidal thoughts, heart and liver failure…or death. Yes! Let’s do this now!!
What if
the “Perturbation Experiment” happens to work? What if it works too well? What
if shortly thereafter a number of Earth’s volcanoes erupt, clogging the
atmosphere and stratosphere with countless metric tons of smoke, ash and detritus?
Hello, Ice Age. I’d be “perturbed.”
Ready.
Fire! Aim.
Oh, oh.
