Scientists Blocking out the Sun 428
Ashtangiman writes to tell us The New York Times is running an article about geoengineering in which many solutions to global warming include decreasing the amount of sunlight that the planet sees. The ideas are not new, many have been around for quite some time, however they have been relegated to the fringes of science and many have never been published because of this. From the article: "Geoengineering is no magic bullet, Dr. Cicerone said. But done correctly, he added, it will act like an insurance policy if the world one day faces a crisis of overheating, with repercussions like melting icecaps, droughts, famines, rising sea levels and coastal flooding."

Blotting out the source of almost all energy for life on Earth doesn't seem smart to me, perhaps we should be working on ways to adapt to new and changing environments instead of trying hopelessly to preserve this one exactly the way it is now.

Instead we should blot out the Sun? That's insane, and therefore even more likely to burn us harder and faster.

The same people who can't get beyond the Rule of Unintended Consequences want to something like this?
Can I take the next ship to another planet now? Either let it evolve or destroy it, but try not to do both.
Why is it the same people who love evolution are the same people who want to keep everything the same?

It's nontrivial, but less nontrivial than leaving the CO2 in the air, leaving the deforested areas bare, or messing with the basic source of practically all energy used by Earth's life, including us.

I will say that such a plan, as a last resort isn't a bad idea because regardless of what the Earth would naturally do we want to keep it habitable for humans. The Earth may go through a natural cycle that would kill us off and we want to stop that, if we can.
However in general we shouldn't screw with things like this because it's clear we have a very poor graps of how climate actually works.

It was just a collective hallucination. We're better now. We just have to keep telling ourselves that, OK?

What we need are real solutions to undo what we've done and at least bring the global temperature down a bit. Remember that article about how the temp is as high as it has ever been for as long as we have accurate records? Yeah, what we're doing is real, you can feel it when you walk outside. Blocking the sun just gives us an excuse to keep doing as we've been doing, not to mention F'ing up the ecosystem in the process.

In the context of humans adapting to nature vs. adapting nature to humans, there is no fundamental difference between preventing the icecaps from melting and putting in better flood control. We are still adapting nature to our needs (i.e. controlling nature), not the other way around. In fact, preventing the ice caps from melting is an example of better flood control.

Today, man is looking out for more and more of it (energy), largely to make more and more of shorter lifespan stuff in China, also to satisfy increasing standard daily-comfort-set for expanding participants of global well-being. This wealth is not diamonds and gold - it is very prosaic, material; manufacturing and using this ever growing mass of shorter lifespan comfort tools is accompanied with releasing significant increase of formerly accumulated energy.
Unfortunately, comfort expectations themselves tend to increase, and almost every person would try to extend and protect comfort, he could achieve. Also, mobility, global tendencies in todays world blur former boundaries of who was capable to have what. The same, not long before poor, China is increasingly serving world to get in return chance to convert nearly each fourth human being into consumer of certain sort. Not much against that, principally, but we have to be very careful and insightful to run all this process so, that mankind wouldn't be sorry after a while. People have quite developed brain and elaborated communication tools - all this could be useful.
As a footer note: reading article I was kicked by this idea, that if melting ice is very first and noticable problem to overcome, perhaps focusing on how to protect this very certain geographically and physically stuff could give us time to think over all the other concerns.

You can say what you want, but a scientist and author as bright as Mr Hawking is not a layman in anything that he talks about as a speaker at a conference.
Do you think that a thorough understanding of math, physics, chemistry, and astronomy, let's say "the universe" has nothing to do with climate? And when a highly intelligent scientist such as Mr Hawking talks about it, he doesn't know what he's talking about?
Wake up and smell the coffee.
A lot of fields of science are quite strongly related. For example, the famous physicist Niels Bohr was definitely not a layman in other fields, say chemistry.

Sure a lot of CO2 is sucked up by the ocean. So what? I don't encourage marine cultivation to sequester carbon because the marine ecology is much too misunderstood to mess with today. What we do know shows how fragile it is presently, under great stress from the Greenhouse (eg. fishing to extinction, vast dead coral reefs from temperature rises). But we do have quite a lot of experience cultivating forests, and controlling growth on land. When all we're doing is replanting existing species in their native locations.
I read your post, and all it clearly contains is FUD - in every direction. Reforestation is a safe way to sequester the CO2 pollution. It doesn't need any more FUD than already put out by the petrofuel companies and their cronies.
