It will be interesting to see how this plays out, because right now the West coast from San Francisco North to at least Fort Bragg, has been suffering a kelp die off of great proportions. No one is quite sure whats going on, but apparently due to climate change, or at least warmer ocean water from further South that we've had for the last 5 or more years, has caused the kelp to die off at a rapid rate, to the point o…

Per various articles I could find on the West Coast Kelp Die Off, it appears that multiple years of warm El Nino waters, a massive starfish wasting disease, and urchin boom resulted in a 3-pronged assault on kelp populations. Now that the El Nino waters have cooled, and the starfish population is returning to normal, 2 of the 3 stress factors are being reduced. The last--the urchin population--is being controlled thr…

We're just getting out of a La Nina according to the climate prediction center (April was the first ENSO neutral month) and El Nino is on track to return later this year with a 50% and growing likelihood by winter 2018.

So I have studied this issue extensively. I personally know Jon Holcomb, the vacuum inventor. First, to dispel any myths. There is zero funding for this effort. It also takes a solid month of effort to clear a football field sized area. Compare that speed to the breeding cycle of the invasive urchin species boom and you have a very ineffective method of population control. Although his efforts were innovative. Jon wi…

I'm not saying that the kelp weren't devastated by those 3 things, I'm saying that the resulting devastation is not permanent. Funding especially is an addressable issue; Patagonia, for example, donates to kelp restoration activities in SoCal and would presumably donate to similar efforts in NorCal if asked.

Hey I agree. Even the ice age wasn't permanent.

The kelp forests near South Australia have all died off as well: https://www.theguardian.com/environment/2016/jul/07/australi...

Is there any immediate economic incentive to adding algae into feed? Wouldn't you agree that markets don't deal effectively with many or most commercial endeavors' unwanted side effects (negative externalities), and so authorities often need to step in when market failure causes damage? In this case, if the science is real, a global treaty would seem in order to simply mandate the effective use of seaweed in cow feed…

Yes, farmers can sell their own use of seaweed additive as carbon "offsets". Environment-conscious businesses buy these credits to become effectively carbon neutral.

"No one is quite sure whats going on, but apparently due to climate change" Look... statements like that, don't help any serious arguments for climate change. To practical-skeptics, you might as well have written "IDK BUT WE BETTER FAVOR SOME COMPANIES WITH TAXES TO BE SAFE" which is a real annoyance of mine. Esp considering other commenters pretty much ruled out your assumption.

AGW skeptics, like evolution and spheroid Earth skeptics are their own audience, no one else is really bothering to tailor their speech to them. We’ve entered the casually dismissive phase of the relationship. The ROI for dealing with people who are in denial is rarely positive after all.

"AGW skeptics" just want a sincere conversation based on science. Like one would say, what about the effects of water vapor on climate change? And pointing out, you can't come to a conclusion and when it is disproven, cherry pick facts to fix your conclusion. It just doesn't work this way. So is it a sincere conversation or what? There's no point to engage with people who aren't honest about the science. Name calling, shaming, or framing them as "in denial" just confirms their observation the conversion isn't sincere.

Wow, thanks for your input. How much different was it 10 years ago?

Can't believe this comment is the only mention of iodine in both the thread and the article. I supplement iodine daily and it's honestly changed my life.

Ditto. Iodine and Magnesium have eliminated my asthma and had other positive effects - no sugar crashes two hours after eating for example.

>I need more dill in my life! Yeah, sure, _until you don't_. Bear in mind that it's essentially an invasive weed if you have a backyard garden. Be careful if you attempt to grow it at home, it might take over.

Eastern swallow tails will take care of almost any dill problem you have. They'll do a number of fennel too, if it is there. Things I've learned hacking in the garden.

I love finding gold like this deep in a thread.
