UK Royal Society Claims Geo-Engineering Feasible
krou writes "The BBC is reporting that a UK Royal Society report claims that geo-engineering proposals to combat the effects of climate change are 'technically possible.' Three of the plans considered showed the most promise: 'CO2 capture from ambient air'; enhancing 'natural reactions of CO2 from the air with rocks and minerals'; and 'Land use and afforestation'. They also noted that solar radiation management, while some climate models showed them to be ineffective, should not be ignored. Possible suggestions included: 'a giant mirror on the Moon; a space parasol made of superfine aluminum mesh; and a swarm of 10 trillion small mirrors launched into space one million at a time every minute for the next 30 years.'"
I would prefer a method that we can reverse if it turns out that we misunderstood a bit of the carboncycle.. so please not the millions of tiny mirrors?
The most simple geoengineering technique would be the most effective one: JUST PLANT TREES INSTEAD OF BURNING THEM
Geo-engineering is a short term last resort solution when everything else fails. It has so many unknown factors that in worst case it can lead to an even worse disaster than the one its trying to prevent.
Reducing emissions is the best way in the long run. Part from reducing the Co2 emissions it drives technology development towards more efficient use of energy, new products, new companies, new jobs etc etc.
We have to face the facts, quick fixes does not exists to this problem, we have to clean up our mess and take the consequences.

Global warming is a scam.

That site is loaded with pseudo-scientific data & outright lies. A few examples:
There is a difference between the FACTS of GW, and the solutions proposed. The only thing that I agree with that site you mentioned, is that some of the policies & the utilization for political ends of GW are questionable.
The planet's fine.The people are fucked.
You're really not listening.. to me or to the article.. geo-engineering is not a short term solution, nor a quick fix.. it's a required on-going effort that will last forever. Imagine you're in a spaceship, what do you need to maintain life? You need active management of your environmental systems or, in the long term, they will fail and you'll die. Well guess what, we are on a spaceship, and it's called Earth.
How we know is more important than what we know.
Worsening water crisis?
The water crisis is not about total amount of water, it is the displacement of water from one point to another.
Water in the form of glacier ice in the Himalayas (providing drinking water for millions and millions down stream), that instead becomes rain in Australia , is a water crisis.

The point in my previous post is that there are already machines available which are capable of capturing CO2 from the atmosphere using nothing else than solar power, these machines are also auto-replicating and their fabrication process doesn't produce additional CO2 emissions. Furthermore some of their subproducts can be used to feed animals or build... buildings (excuse my poor english pleas). We have these machines already. We know them as PLANTS. I'd rather not get into the real motivations of the current push in favour of geoengineering, but I'm sure it comes from the same people always trying to make money from human disgrace.
Or we could just have a brief and rather blunt conversation with our friends in the coal, oil and beef industries.
Which is what world leaders are tiptoeing around trying to avoid, pretending terrestrial biofuels were an option, pretending carbon sequestration is an option. All of this stuffing around to avoid some uncomfortable conversation about facts that both the politicians, the people and the companies know are true.
Must we be stupider as a species than our individual parts ?
I make that 10,000 launches which over 30 years is nearly a launch a day. I was under the impression that rocket launches have a negative environmental impact not including the impact of actually building so many.
The obvious solution here is to build an orbital cannon. The biggest built and successfully used was in the 60s by the U.S. Navy to launch atmospheric probes up to 100 miles into the atmosphere. Building a 50-100m long gun up the side of a mountain(or even underground in a mine shaft or silo) isn't that technically hard. Estimates for the gun itself run about 200 million to build. The idea is to have each payload have its own small positioning rocket and external case. Drop the mirrors in the case and lob into space - the small engine moves it out to the proper position. Since we're talking just scattering the mirrors, there's nothing else required here - just position and open it up. Once a day is trivial. 10,000 launches would cost a mere 1-2 billion dollars. Even if it required 10x that many launches, with it firing off every couple of hours, it would be simple enough to accomplish. With ten of them, this could be done in just 3-5 years.
2-3 billion for an array of ten of these. Problem solved in a new years.

This is the latest company that is working on this. They will have a test-launch next year.
not to Australians like me ... there's so little water here that we have to survive on beer.
1. Swindle?/Scam?/Fraud? Perpetrated by who? For what purpose? Who (which golem "them") gains exactly what from preventing this "global warming/climate change" that "they" say is happening and you insist is not? What is their payoff? And why are you so dead-set against it?
2. Are you seriously denying that humanity has, since the start of the Industrial Age, pumped trillions of tons of carbon (we'll ignore the sulfides, the chlorine, etc.) back into the atmosphere that have been locked away as coal and oil for hundreds of millions of years? Really? That just didn't happen? Really? It couldn't possibly have an effect? Really? And you're certain of this, how?
3. What's it to you? Why does it bother you so that people are worried about this and want to do something about it? Why are you so determined to stop them doing so?
Facepalm.
Increased ocean temperatures == releases of methane hydrate == more atmospheric methane == increased ocean temperatures.
Have you heard of the notion of "tipping points"? Runaway positive feedback?
Can you name THREE? Reputable environmental scientists, climatologists, even (real) meteorologists? You know, scientists with expertise in the field we're talking about? Do they have any, what's that word, evidence? Because the glaciologists and geologists and oceanologists are pretty convinced that something pretty wildly out-of-scale for the time frames involved, (in the absence of any other environmental factors: supervolcanos, large meteor strikes) is going on. Do these reputable environmental scientists really think that climate change isn't a real and worrisome threat, that mankind's stewardship of the planet hasn't been incredibly shocking irresponsible?
No folly is more costly than the folly of intolerant idealism. - Winston Churchill
You believe what you want.
No, I believe the facts. My personal desires are irrelevant.
You don't need to be a scientist to realize which side is correct.
Yes, you do. AFAIK, climatology is a science.
The nasa article in the link speaks for itself.
Which essentially means you didn't even bother to verify it by going to the NASA site I mentioned. Looks like it is YOU who believe what YOU want.
I don't care who John Coleman is what he says makes sense.
He doesn't make sense. Weather is distinct from climate. He is not qualified .
The court case involving the gw swindle ended in a decision that the content was essentially true.
Ofcom, the UK media regulator has ruled that The Great Global Warming Swindle was unfair to the IPCC, David King, and Carl Wunsch and breached a requirement of impartiality about global warming policy.

Excess CO2 has nothing to do with global warming in fact rising CO2 is an effect of increased global temps not a cause. The US senate means nothing. The hundreds of scientists that disagree with the climate change fraud do. Think for yourself for a minute. CO2 is what we exhale and what plants inhale. A good case can be made for the good caused by a warming planet. The facts indicate that there has not been any warming. Studies have shown that incorrect measurements taken in hot heat island city environments can account for the change.
You're repeating the same old already disproved fallacies over. Go to the NASA site I mentioned earlier & try your best at looking at the facts.
Natural variation makes a lot more sense than the idiocy of the global warming "proof".
Natural variation has been disproved by NASA.
Go on and believe the few "experts" ignore the others and follow what Al Gore says.
I believe the facts, and that independently of what Al Gore might think. BTW, the "few experts " are the majority. That includes NASA who has the largest concentration of climate scientists, the academies of sciences of 27 countries, and all the major scientific institutions like National Oceanic & Atmospheric Administration, American Geophysical Union, American Institute of Physics, National Center for Atmospheric Research, American Meteorological Society, US Geological Survey etc...
And in contradiction to yourself, trees are actually responsible for helping create water. Ever seen a desert with trees? Nope...
Also, trees create wind. Notice how whenever it's windy, the trees are always flapping about?
