One of the big ironies of superhero comics and movies is that these beings of immense power, though committed to saving the world, do so by punching things pretty hard. Even when far more obvious solutions to world shaking challenges are presented, the question is not “what will do the most good for the most people” but “can I punch at it really, really hard?” Superman could have done far more for his adoptive home world if he used his limitless strength to turn a crank on an alternator.

Weinersmith knows what’s up.

Heroes in the Marvel Cinematic Universe don’t fair much better. While off avenging, sorcering, and civil warring, they’ve managed to overlook some fairly self-evident solutions to the most pressing global crisis of our time. So how could Earth’s Mightiest Heroes bring an end to runaway climate change?

1. Tony Stark creates unlimited free energy.

We can get the obvious one out of the way, first. Stark’s Arc Reactor is, for all intents and purposes, a free energy machine. Miniaturization means Arc Reactors could be used to power anything, from cars to aircraft carriers to entire cities. Switching the world’s power grid and transportation network to Arc tech would result in an immediate reduction in CO₂ emissions and halt the accumulating damage of continuous energy growth as demand for technology increases around the world.

Ok, that’s the obvious one that has to be mentioned in order to avoid insufferable Twitter comments. Now on the the good stuff.

2. Use Pym Particles to sequester CO₂ in the Quantum Realm. 

Pym Particles are particles that “shirk the spaces between atoms” allowing an object bombarded with these particles to shrink continuously while maintaining its mass, unless it’s a tank on a key-chain, for some reason. Comic books are ridiculous, ok?

Unfortunately, the shrinking power of Pym Particles is limitless, and once an object shrinks to the point where it’s smaller than an atom, somehow, it enters the Quantum Realm, where the laws of Newtonian physics no longer apply, time is meaningless, and you can never escape (except when you can). Shrink into the Quantum Realm and you shrink forever. That really seems like the ideal place to sequester CO₂ , doesn’t it?

The big problem with carbon sequestration is that it’s not always a permanent solution. Sequestered CO₂ in trees is only sequestered so long as no one cuts those trees down and burns them. The carbon is still out there in the world, waiting to be re-mobilized into the environment. But! If we could sequester carbon by bombarding it with Pym Particles and sending it to the Quantum Realm, it would shrink forever, permanently locked away in a world of very poorly interpreted quantum physics. That seems safe.
