Right. We disagree.
These are very interesting:

Wrong Again: 50 Years of Failed Eco-pocalyptic Predictions
Modern doomsayers have been predicting climate and environmental disaster since the 1960s. They continue to do so today.
1] None of the apocalyptic predictions with due dates as of today have come true.
What follows is a collection of notably wild predictions from notable people in government and science.

Now, I am not saying that these NEW predictions being made are not accurate. I am not denying that AGW is a reality, either. I am simply going on our previous history of making these kinds of predictions.
We constantly make poor predictions in regards to Earth's climate. I don't think the predictions are any more accurate, now, than they have been in the past, however. I DO think we have decades and not "12 years" as the latest predication says.
I could say the same about you. Shall we dispense with this sort of talk?
I don't deal with impractical ideas. That is what I found the proposals that you suggested, to be. That's all. 2] It doesn't matter who initially made the proposals if they haven't fully thought them thru.
1] If none of the predictions have been accurate, then either you are asserting that all the predictions have not been accurate, or the source cheery picked the predictions to only tell you about the ones that have not been accurate.
OK, I'm not going to defend the predictions that were made 50 years ago. We have had 50 years of improvement in computers and computer models. So, 25 years ago we had had 25 years of improvements. So, I think we ought to look at only the models from the last 25 years.
I saw a report the looked at many, IIRC, 14 models, from many years ago. The predictions that that they made were wrong because they had to assume how much CO2 and other GHG would be added to the air. The study used the 14 original models and replaced the original wrong data with the correct data [that we now have because it is in the past now]. It found that almost all, IIRC, of the models' new predictions were within the predicted range of accuracy, that is on the error bar, not off the error bar.
. . The authors asserted that this means that the models actually did a pretty good job of predicting how the world would heat if the original authors had been able to accurately predict the correct levels of GHG in the air.
. . They said that this means we can be confidant that they will fairly accurately predict how the world will heat IF WE CAN
NOW ACCURATELY PREDICT WHAT THE GHG LEVELS WILL BE IN THE FUTURE.
This seems to refute your reports that all the old predictions were wrong,
and so we can be confident that the models being used now will also make bad predictions about the future.
2] You obviously didn't do any digging to see what the details of the 3 solutions I gave you actually are. You just assumed that the scientists didn't do any calculations to see if they would work and if they are possible, etc. I did see in the original sources claims that the original scientists did do such calculations.
For example, the SO2 sprayed from passenger planes only uses planes that will be flying people or cargo anyway. No new planes will be built and no flights will be made without passengers or cargo. So, the costs will be very low. The objections were that someone would have different weather as a result of the spraying and they can sue for damages, and that we can't be sure we will not make things worse, and just recently, that if the program must stop for any reason, then the result will in just a week be that all the cooling will end, so the temp will spike. It is like carrying a parasol for shade to keep you cool so you don't die which you would without the parasol, and suddenly the wind blows it away, and now you will die because you don't have that shade any more. But, we are going to die if we do nothing, so why not give it a try?
The converted ships making clouds over the Arctic Ocean doesn't need that many ships. Less than 20, I think. Compared to carbon capture & storage, this requires a trivial amount of energy. And it is not forever, it is just to keep the CO2 and CH4 in the Arctic region out of the air and in the permafrost or on the sea floor as a form of ice, while we reduce our burning of carbon fuels. [I just now saw a report that there is 1.4 trillion metric tons of CH4 on the sea floor. This is over 1000 times more than is in the air now. We must not tip the tipping point that releases this into the air.] We do not have decades.
