That's assuming we don't have a Conservative government later this year.
Polls are trending Liberal.. stand by. It’s a long summer ahead and the Conservatives are short on real answers.

#202“To carry out this plan, it will take a volume of 7 cubic miles of olivine rock placed on 2% of the world high-energy, tropical shelf-seas each year.” To put this in perspective, the global annual oil production is about 1 cubic mile [1], and concrete production is about half a cubic mile [2], [3] (4.4 BN tons at 2.4 t/m3 = 1.83 cubic km = 0.44 cubic miles) [1] https://en.m.wikipedia.org/wiki/Cubic_mile_of_oil [2] ht…

#203It costs about $1 to transport an oil barrel 1000 miles. 35 billion oil barrels are transported each year. So transporting that olivine rock will cost an order of $250B. This will compensate for the yearly co2 emissions , ~38B tons. With carbon offsets priced at $15-$40 per ton - so there's potential for profitability .

Everyone's problem, no?
Not really. Poor countries don't have expensive infrastructure investments in the current climate, so can adapt to climate change by moving a few miles. Moving New York City and Los Angeles is much harder, and the loss much more expensive.

#205Well jeez. I know it's not a popular thought on HN, but climate change is a problem of such scale that it's going to need government-level funding and oversight to find and validate geoengineering solutions, and global-level funding and coordination to implement them. This third-way aspiration to a non-government solution just seems like a pipe dream.
Could it be the case that contemporary governments and economies are just simply not structured to be forward thinking in this way? What if, in analogy to the transition out of feudalism, the next evolution of government and economies is one that allows for spending on future outcomes in a way that is impossible now? I have no idea what those institutions would look like -- I only know that hoping to solve global pro…

> Could it be the case that contemporary governments and economies are just simply not structured to be forward thinking in this way? I'm confused that this is a quesiton that you're asking, as opposed to something that is blatantly obvious. The United Nations declared as such recently: https://www.theguardian.com/commentisfree/2019/mar/18/ending... https://www.huffpost.com/entry/climate-change-capitalism-eco... "Tru…
By analogy to feudalism that we need a transformative change to something, an unknown something, that is different but a little better at seeing a big picture rather than endless blinkered dogma.

That’s to counteract for 100% of emissions, right? A more reasonable goal would be to go for 10%. Still very ambitious, but could be done and would have a pretty huge impact. Combine that carbon pricing, technological advancements, and other sequestration schemes, and targets for avoiding environmental catastrophe seem achievable.
Sorry, can you explain why you think counteracting 10% of emissions would have "a pretty huge impact"? The best science from the IPCC suggests we have to cut net carbon emissions by 50% by 2030 in order to have a moderate chance of avoiding the most catastrophic effects of the climate disaster. I'm not saying 10% isn't ambitious, but it's entirely insufficient to the scope of the problem.
The IPCCs primary goal is to reduce carbon output, not figure out a way to enable it to continue. We have renewable and sustainable power technologies ready to reduce carbon output rapidly as soon as the political will to proceed is won.
This potentially huge mining scheme involves releasing what is in simple terms very large amounts of a pollutant into the Ocean. Its anticipated that the effects of this particular pollution will be beneficial, but we have no natural history to show for its ecological effects. Forests are already a great part of our worlds natural history.
I think it is a worthwhile scheme to begin implementing and observing the effects on Ocean ecology and also on the global mining industry which it has potential to stimulate. But the 100% target is an oversell in my view.

Hi, if you'd like to donate at this point please check out https://projectvesta.org/donate where we currently have our "Grain of Hope" necklace available. It is a single grain of olivine, suspended in a sand timer vial, to symbolize that although time is ticking, it is not too late to stop (and reverse) the damage. Since we do not have a beach yet where we can place olivine, we were originally not planning to offer t…
Setup recurring donations as soon as you get around to it. It's a lot more money, and a lot easier to plan your budget since attrition is perfectly predictable.
