№ 549: Home Improvement

Why We Stink at Tackling Climate Change

Global threats result from human culture outrunning human biology.

Our biologically evolved selves are quite good at perceiving events that are prompt and threatening; those that are slow-moving, although equally threatening, not so much. A fire in a building and people run outside. A slow moving fire in the Earth’s thermal budget and people hardly notice. For nearly all of our evolutionary past, it was not adaptive to detect such slow-motion changes, and so our ability to do so is limited.



The Risks, Rewards and Possible Ramifications of Geoengineering Earth’s Climate

Injecting aerosols into the stratosphere could help cool the planet, but scientists have yet to study exactly how such solar geoengineering would work

Researchers have proposed brightening clouds, making sea spray more reflective, or even launching a giant mirror into space to reflect extra sunlight. The most promising and affordable of these methods is stratospheric aerosol injection, which involves spewing tiny particles into the upper atmosphere. Those particles would reflect sunlight away from the Earth, effectively dimming the sun and, in theory, cooling the planet.

That's how things go, we evolve in slow-mo
and we never have the foggiest no-
tion of what to expect from downstream effects
that flow from (misguided) “improvement” projects.

It's not that complex, we're vexed by biology.
We see no need to utter apologies
for mistakes that were made. (Which were inevitable.)
Just wait, next time, we'll be incredible.

(I would speculate — strictly between us —
this aerosol thing is what happened to Venus
where life evolved before here on Earth.
Just my opinion, for whatev' that's worth.
But all of this stuff is taking a toll.
Perhaps we'd be safer burning more coal.)
