It is possible to cause a huge (short term possibly reversed) increase in carbon capture by algae by dumping iron sulfate in the ocean. On the other hand, uh, well, maybe it won’t work and you will just get a few tons of fish (not many tons of carbon containing detritus on the bottom of the ocean.
Now the general principal seems to be that, so long as there isn’t proof beyond reasonable doubt that a proposal will work, to stick to the tried and true and first do no harm but rather wait until the tundra melts, methane is released, and the climate is irreversibly altered.
This makes no sense. Conservatism may make sense if the choice is between the current state (which is not ideal) and gambling on something new. It makes no sense if one is careening towards a precipice, as we are.
There is an, as usual, interesting post at Vox.com. Kelsey Piper discusses the unfortunate fact that rogues might attempt to fight climate change without scientific proof that ocean fertilization works and without international regulation of ocean fertilization. Personally, I think the near certainty of climate catastrophe if we stick to the current approach is a more serious problem.
The current approach is international negotiations to reach non binding agreements which from which Donald Trump withdraws the second largest carbon emitter.
In contrast, the dangerous rogue approach is something allowed by current non law, conducted by Native Canadians which had the side effect of a record salmon harvest.
I want to address two questions. First should we dump Iron Sulfate in the open ocean. I think the answer to this question is obviously yes. I have read no argument with any trace of possible validity against it. I might add that it works better if mixed with silicate and seeded with marine diatoms. But in any case, I have seen no argument anywhere that there is a non negligible risk of undesirable side effects.
Yet the official response, such as it is, is to condemn the efforts and seize everything that can be seized.
I attempt to understand what the hell is going on after the jump.
But before that I note:
What happens when some individual or country wants to go big in the battle against climate change without buy-in from their neighbors? Could a country unilaterally pursue climate solutions that, unlike ocean iron dumping, pose substantial risks?
Note the insanity. In a post on ocean dumping of iron sulfate, Piper says the real issue isn’t any possible bad effects of ocean dumping, but the fact that someone might do something else which is bad some time. But note also that even a tiny country which has authority over a lot of ocean could unilaterally dump iron sulfate. The country doesn’t need a lot of land area. The country doesn’t need high altitude. The country’s average elevation might be two meters above sea level.
Why doesn’t Kiribati dump all the iron sulfate they can buy in the huge expanse of ocean around their tiny soon to be drowned atolls ? What do they have to lose ? Who is going to stop them ? The side effect would be more fish around Kirbati. The policy would make sense even if oceans weren’t rising.
OK so what’s the problem ?
