Blocking Out the Sun Wikimedia Commons

Of all of C. Montgomery Burns’s nefarious dealings on The Simpsons, perhaps none sticks in the public consciousness like the time he attempted to use a massive shade to block out the sun (most notably because doing so led to his being shot by a vigilante baby and an uncharacteristic two-episode event). But the U.N. may soon put all such plans to blot out the sun – villainous or otherwise – on hold.

The U.N. convention could choose to take up this topic – no joke – during the tenth meeting of the Conference of the Parties to the Convention on Biological Diversity going on until the end of this month in Nagoya, Japan. It might sound a bit sci-fi, but some in the scientific community have advocated reducing the amount of sunlight reaching earth to slow the effects of global warming.

Doing so requires launching some kind of medium into space to deflect the suns rays. Some schemes call for placing a large lens or something like it out at the Lagrange point between Earth and the sun to deflect a small percentage of the sun’s radiation away. Others call for placing many billions or trillions of tiny objects between us and the sun. All are estimated to be very expensive and it’s not at all certain that any of these ideas would work. But they have been seriously considered; even NASA and other reputable space organizations have looked at the idea, even if only to keep an open mind.

But the U.N.’s interest stems from the fact that if it’s unclear whether a shading scheme would even be effective, it’s even more unclear what the ramifications would be if one was. Such an experiment could have unforeseen effects on climate and ecosystems back on Earth, and that could cause problems ranging from drought and famine to extreme weather systems or even, in extreme cases, extinction of some species (hopefully not us).

Regardless, it appears the U.N. aims to look into banning sunshades or at least limit research into them, choosing instead to face the global warming crisis with solutions here on Earth. Bond villains and unscrupulous cartoon energy magnates, take note.

No more umbrellas or sunglasses!?

What about painting every roof white. I thought about this back in 2003 during college when I learned of the heat cycle in a basic atmospheric science class. Albedo.... anyone????

Within the last six months I read some articles on main stream media about that same idea as though it was brand spanking new! It seems so cheap and I bet highly effective.

Bummer... Now what should I do with my ultimate sun blocking/shading space ship?!?! :)

Be reasonable, at the time we build any useful space vessel for this purpose, we will be long time over "green gas" problem.
To the space, boys! :)

All the nasty stuff happening in the world today and THIS is what the UN spends part of their time on? They don't even have the authority to enforce any such rule should they decide on it.

@lcpltom: Though to be fair, nobody has the authority to tell the UN what to do, either...

I was just talking about this on the mars colinization page! What if we start on mars with development? We could launch a probe containing nano particles that could either block light from the sun or reflect light back to the surface. If we designed it well you could even control the difference and literaly control surface temperature throughout the entire planet. Maybe control with localized PID control with setpoints established via remote laser programming. Why is the U.N. impeedeing all the geo engineering projects?

Could it be because they stand to loose power and influence if we could simply turn up or down the temperature when we needed and they couldn't regulate carbon because global warning was defeated?

Shit, my evil plan, ruined. Wait a second, what's the penalty for blocking out the sun again? Its not like any nation has the level of spaceflight competence to stop me anymore, mwahahah!

Yes that's a swell idea, let's think of ways to block out our primary source of heat and energy so that we can finally defeat global warming! It's not like that could possibly interfere with our ability to survive or anything.

Sure global warming is still an uncomfirmed theory with very little historical data to back it up, and of course recent events have called the reliability of that data into question, but the UN and Al Gore say global warming is the real deal so this is clearly the best option.

"Since the beginning of time man has yearned to destroy the sun."

-Mr. Burns

Just when we finally had an opportunity to really screw up the planet forever and someone comes along and ruins all the fun. You know if we tried this the law of unforeseen consequences would immediately rear it's ugly head. All the genius' involved will say. "I didn't think of that."
Followed by the ever popular "Aw Sh*t" It happens every day.

The problem with this law is that it leaves us without life jackets. Entiandanlo: Global warming will not stop because the big companies are not going to stop and fail to make billions of dollars in fossil fuel use. In addition, developing countries will continue burning coal in power plants because it is cheaper and politicians in developing countries prefer to use what is cheap to be able to steal the rest of our tax money. The amount of carbon dioxide and produce methane gas is so large that the solutions we apply on the ground will cause a small effect. The planet will continue to warm, and the domino effect by breaking underwater methane deposits go crazy weather. That and a thousand reasons will require a solar shield at the Lagrange point between earth and sun. But the only way to do it cheaper is to launch a capsule with powder to be launched with magnetic catapult. The magnetic catapult is not a luxury, it is something necessary for human survival. Cancel all other astronomical research projects and give priority to the construction of a catapult magnates in the land and a less potent on the moon europa, to launch ice continuously for terraforming Mars as fast, it seems that we need shelters ahead of schedule.

El problema de esta ley es que nos deja sin salvavidas. Entiandanlo: El calentamiento global no se detendra porque las grandes empresas no van a detenerse y dejar de ganar billones de dólares con el uso de combustibles fósiles. Además, los paises en desarrollo seguiran quemando carbón en plantas de generación eléctrica porque es más barato y los políticos de esos países en desarrollo prefieren usar lo que es barato para poderse robar el resto del dinero de nuestros impuestos. La cantidad de dioxido de carbono y gas metano que producimos es tan grande que las soluciones que apliquemos en la tierra causaran un efecto pequeño. El planeta se seguira calentando, y el efecto domino al desprenderse los depositos submarinos de metano enloquecera el clima. Eso y mil razones más harán necesario un escudo solar en el punto lagrange entre la tierra y el sol. Pero el unico modo de hacerlo barato es con el lanzamiento de cápsulas con polvo que sean lanzadas con catapulta magnética. La catapulta magnética no es un lujo; es algo necesario para la supervivencia humana. Cancelen todos los demas proyectos de investigacion astronómica y denle prioridad a la construcción de una catapulta magnatica en la tierra y otra de menos potente en la luna europa, para lanzar continuamente hielo a el planeta Marte para terraformarlo de rápido, que parece que vamos a necesitar refugios antes de lo previsto.
