Can Anyone Stop the Man Who Will Try Just About Anything to Stop Climate Change?

There's a few key ideas here: The limiting factor in plankton growth is iron. So we can hit it with other things, the plankton needs more iron to incorporate into chloroplasts to grow. Algal/plankton blooms can be toxic from the chemicals produced, but they are usually toxic because they deplete oxygen in the environment. I suspect that this would be manageable in the ocean, since there's constant mixing and the ocean is _big_. http://oceanservice.noaa.gov/facts/habharm.html
Iron seeding of the ocean already happens, in the form of dust storms blowing onto the ocean. We've been able to see the effects of it, and it does as it says-- it increases plankton life in the ocean.
I think that a lot of posts here are underestimating the size of the ocean or over-estimating the capability of humans. We would have to dump so much iron into the ocean to make the whole thing anoxic. If we did this in a controlled manner (and in small paths, so we wouldn't end up with big un-mixed anoxic patches) then I think this is very reasonable.
All of you should be careful not do have the knee-jerk "nah that sounds crazy!" reaction. This is HN, and you ought to know that the disbelievers don't have a good track record.

With the caveat that we must be cautious not to use statistical analysis of the data to lie outright, I want to say:
Any attitude that does not at least INCLUDE the one Russ George advocates about LETTING THE DATA TELL YOU what is going on is ANATHEMA to science, Western Society, and human life in general.
Seriously.
If iron seeding works and causes no calamity we can't handle, we'd be derned fools not to do it at some point, assuming we need to of course.
Then again, what is the preferred equilibrium for the planet and how do we know that? There wasn't always widespread environmentalism and I've heard the idea that environmentalism in its present form emerged only after computers became more widespread ( from "All Watched Over By Machines..." by Adam Curtis.)
Is that crackpottery or is it a salient observation? I can't even tell any more.
Under that view, things like biodiversity are valuable because they contribute to systemic stability - we can exterminate a species if we need to, nobody has to give us any further 'right' to do so (as in a typical attidue, "What gives you the right to play God with Nature?!")- but it is wise to take a preservationist attitude until we have a proven track record of creating long-term, moderately stable ecological systems - until we can replicate our 'Starship Earth,' we'd do well to keep from destroying it! In other words, at least for me, the currently preferred equilibrium point is one that maintains a semblance of the historical ecology's relative balance, because that's the kind of point where I and my descendants get to not go extinct, and once we can reliably replicate and control such ecologies, it won't matter much anymore, we'll be in a position to choose what happens to which things - right now is the tender point where can destroy naturally developed situations, but cannot reliably replicate them.
The shock from "All Cared..." is - what stability? Which equilibrium? If we choose them, how do we defend our choices? Obviously, nobody was doing this 70,000 years ago ( at least presumably not consciously ) and here we are, so...
To a single-digit approximation, all species are extinct. Is it hubris to think we're smart enough to keep from destroying ourselves, or that we're powerful enough to destroy ourselves?
Suppose we add Pigou carbon taxes. Does that mean poor people suffer more? So can we exempt them? Then isn't that sort of ... Empire-ey, the sort of thing a 19th Century Brit like Rudyard Kipling wrote about?
I find the various anthropic principles to be of good use for this sort of thing.

Total worldwide production of plastics looks to be about 250 million tons, and they are estimating that about 8 million tons per year make it into the oceans. From the paper, but not the gloss, is that fact that China is by far the leading offender in this, followed by Indonesia, Philippines, and Sri Lanka. India is in 10th place, and the US in 20th. Coastal Europe combined is about the same as the US.
Acrylic clothing sheds microfibres. These are too small to be caught by washing machine filters, and they end up in the sea doing the same thing as plastic microbeads.
Those are now banned, no?
But a plank in your favor - the people who settled the regions where environmentalism has its most fertile soil are on a line of thinking from the old, rock-ribbed Congregationalist and Unitarian preachers from New England. ( source: "American Nations..." ISBN-13: 978-0143122029 )
The interesting thing for me over the controversy when this was being done was that it reiterated the concern that nobody feels they know how to direct climate change. As a result the only action they can endorse is "affecting it less" by reducing our own carbon emissions. This guy is taking it from the other side saying, "Let's start driving the model and get it to a point we like."
That's an artifact of the propagandistic nature of the actors in the issue - on both sides. I believe they do that because it better meets their goals. They have a need to win. And it's not an imagined need - the issue has slipped into an adversarial shape.
The article exposes this well - people are well-bifurcated around two poles - 1) it's the end of the world or 2) it's no big deal.
Maybe that is right, but I rather expect there's something else in play ( because the timescales are fairly long and we're bounded by out ability to learn ) , and that the more productive approach will be more moderate and possibly more experimental. Taking the position of "no, everyone must modify their behavior" does not seem the most reasonable of all possible positions.
But I am just interested in it as a problem to be solved, not as a means of winning something.
IMO, all the furor seems more likely to produce heat than light. It's slightly crank-ey but I still enjoyed Chrichton's "State of Fear" immensely.
Flip the switch, because if the fresh water influx in the North Atlantic shuts down the global conveyer currents, it won´t be warming we´re looking at, and it´s great news for India, and Bangladesh, and a catastrophe in the Northern Hemisphere, Europe in particular.
A great empire is always about to fall...
The mainstream opinions seem to be:
1. Climate change isn't real or isn't a big deal.
2. Climate change will be a global catastrophe or even lead to human extinction.
Now, it would be reasonable for the people in group 1 to complain about geoengineering experiments, but actually they don't seem to care. And the people in group 2 are pretty much to a man saying, "Climate change is a huge problem and the only solution that we are willing to entertain at all is cuts to carbon production with no offsetting energy production except through solar and wind -- even though these are clearly not politically feasible in large enough amounts to make the difference, and indeed even though there's growing evidence that even unrealistically massive cuts won't solve the problem."
This suggests that there are some unstated facets to the beliefs of people in group 2.
The truly catastrophic climate change - human extinction - outcome is the runaway greenhouse scenario. That´s been floated, but it runs into the evidence that the earth has been considerably warmer before (both poles melted) without that happening. But I suspect it will get another look after this year.
The slightly less catastrophic climate change outcome is the next ice age being triggered. We know what causes them, but there´s a fair amount of variance as to when, and we don´t know what the exact trigger is. The next ice age though, isn´t a catastrophe everywhere, in particular there´s a lot of reasons to believe India benefits for example.
A general warming accompanied by a significant sea level rise is a catastrophe for Bangladesh (most of which is below 10metres above sea level), the Pacific Atolls, India, South America and Africa (heat extremes) extremely expensive for the USA, and Europe, and good news for Scandinavia, Canada and Russia.
However, the general tone of the climate change debate for the last couple of decades, is not such that it would encourage a nuanced debate about the possibility that it could go either way. Nor is the planet really ready for a reasoned debate between its two hemispheres as to which outcome would be preferable, and for whom. However, the rise this year though has even the alarmists scared - especially with the suspicion that it´s entirely probable that there´s been a tendency for scientists to favour the less extreme predictions when modelling the problem, and even those have been bad enough.

This field does not have great track record. See, for example, the introduction of the Cane Toad to Australia: https://en.wikipedia.org/wiki/Cane_toad#Australia
At the very least, look at the opportunity cost. You can have climate change as it's moving now. Or you can try your best at political solutions (good luck stopping China&India's economic growth and associated pollution). Or you can try some geo-engineering.
"...and that is how we know the earth to be banana-shaped..."
If you think it's impossible for a single organism to have an effect on climate you're mistaken. Wolves, once reintroduced to Yellowstone, have changed the entire park, altering water flow on a massive scale: https://www.youtube.com/watch?v=ysa5OBhXz-Q
"Our results contribute to a growing body of evidence showing that changes in growth of woody deciduous plants following the reintroduction of wolves cannot be explained by the trophic cascade model alone"
I don't get it. Which side are the rabbits?
What this person is trying to do is seed plankton. Plankton, as anyone who grew up near a coast can attest, commit mass suicide as they over-bloom. This is called the red tide and it caused me to spend a lot of evenings after beach days itchy with watery eyes. It also kills enormous numbers of fish, whales, jellyfish, etc.
EDIT: I can't reply, but I saw your comment that "unlike the cane toad, iron can't reproduce." Unfortunately, you're in error. Iron, like a lot of metals and toxins, can bioaccumulate in the food chain, pass from prey to predator and from gestating mother to fetus, and persist in ways that cause all kinds of havoc [1]

Maybe there is some sort of trade off point here. Where the C02 reduction saves more wildlife than what ends up getting killed off by the toxic blooms?

[EDIT:] thanks for the info! TFA went on and on, yet somehow omitted the explanation for iron...
Optionally, we could use volcanic ash instead. But only because it contains a lot of iron. :)
Your sarcastic tone is a great example of how deeply everyone has their head in the sand.
