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.
How so? What difference is there between emitting zero and emitting x kilograms and sequestering x kilograms?
