Bill Gates Funds Seawater-Spraying Cloud Machines

lucidkoan writes "Environmentalists have long argued about whether geoengineering (using technology to alter the climate) is a good way to tackle climate change. But the tactic has some heavy hitters on its side, including Bill Gates. The Microsoft founder recently announced plans to invest $300,000 into research for machines that suck up seawater and spray it into the air, seeding white clouds that reflect rays of sunlight away from Earth. The machines, developed by a San Francisco-based research group called Silver Lining, turn seawater into tiny particles that can be shot up over 3,000 feet in the air. The particles increase the density of clouds by increasing the amount of nuclei contained within."

    Unfortunately, the machines are solar-powered.

    The problem is, nature is never in a "balance". Forest fires, wild fires, volcanos, tsunamis, global cooling, ice ages, global warming, desertification, floods, forestation, those things all happened before, during and after man.

    I'm from South Dakota, so I've looked alot at the geological history there. It used to be under the sea, under glaciers, partially under glaciers, burned by wild fires that crossed the entire region, forested, then less forested, it used to have volcanos, it's been covered by ash from other volcanos, it will be covered by ash when Yellowstone cooks off.

  4. $7 billion is peanuts to stop global warming by wonkavader · · Score: 5, Interesting

    The article says that 3 ships is nothing. We need $7 billion worth of ships to stop the temperature from increasing.

    WHAT? We can stop warming in its tracks for just $7 billion? That's very little money.

    How were you modded insightful? The simple fact is, that the h20 is not the issue. It goes up, it comes down. In addition, when water is in the form of CLOUDS, it COOLS the planet. It is when it has a high vapor, but not enough to form clouds, that you get warming. OTH, the CO2 is an issue because it stays around and around and around. As such, a VERY small amount goes a long ways. So, the global warming issue is just garbage.

    I will say that there are OTHER possible side effects, for example, the clouds WILL block sun from getting to the crops, so there will be less food. And I am sure that there are other ones that are not thought about.

    I know it's slashdot, but I would still like to point out your remarks have nothing to do with the technique described. Besides that, 76% + 1/3 > 1, so you should go over your numbers again...

    They talk about producing clouds, not water vapor. Clouds are made of liquid water in tiny drops, forming from vapor around some sort of nuclei, it's actually mentioned even in the summary! The energy issue need not be that much of a problem. Energy is needed, but how much? Probably nothing relevant to global warming, so it's just a matter of cost.

    The problem of salt is also insignificant, given the task is done deep in the ocean. The salt will not get carried for 5,000 kilometers without a huge drop in concentration, if at all.

    Having said all that, further tests must be carried out, of course, we still have no backup planet. From what I understand, that is the whole point in investing in research.

  8. Re:Isn't water vapor... by bunratty · · Score: 5, Informative

    Yes, water vapor is a greenhouse gas. But putting more water vapor in the atmosphere will not contribute to global warming, because any excess water vapor put into the atmosphere precipitates out as rain, snow, or dew within about a week. In other words, water vapor is not a forcing.

    Excess carbon dioxide, on the other hand, can remain in the atmosphere for hundreds of years. That's why burning fossil fuels has the effect of increasing the concentration of carbon dioxide in the atmosphere, leading to warming.

    Because last time I checked, when I stuck my tongue out when it rained, I didn't taste any salt at all, and I am 99.9% sure that the rainwater I drank used to be in the salty seas not too long before. Just because it seems to fulfil symbolic logic doesn't mean it's true.

          You obviously have never lived near the ocean. The rain isn't "salty" enough to be tasted, but there is salt in the air. Anything that can be corroded will be corroded faster near a body of salt water.

    No. It will be down moderated because it is a moronic post, and it uses way to many words to convey the BS.

    The Yellowstone Caldera will take many years, probably hundreds of smaller eruptions before any major super-volcanic eruption. Your statement that it is 40 thousand years overdue is not based on any reasoning and no geologist would agree with you.

    Global warming is real. It is caused by humans contributing shit-loads of Carbon to the atmosphere. It will have consequences on the human race. There is probably a tipping point where the changes in the planet will be dramatic.

    p.s. It serves me in no way to be taking this position other than the fact that I kind of give a shit about the future of our species.
