The complete lack of any coherent PLAN is very telling in my mind.  That's because the folks who have looked at the problem realize we are too late in addressing it.

Nuclear is off the table.  No one can present a serious way forward with costs and benefits.  And the MIT group clearly shows that even stretching goals are insufficient.

I realize many here are not technically trained and perhaps don't understand what the term PLAN means.  it is not some aspirational setting of goals someday out in the future.
Again, there are no shortage of plans. There is a shortage of political will. Of course one paragraph about the Paris Accords is not a complete plan. To think so would be silly. But to think there aren't thousands of ideas bouncing around is also silly. Declaring nuclear off the table is just an example of the issue. Nuclear isn't off the table, it just isn't popular politically. Like with covid, all plans are more or less making tradeoffs and living with uncertain outcomes. None of the choices are popular, and so we tend to default to nothing.

Why can no one here cite a plan?

And this remark about the Paris Climate Agreement is stunning, to me:  "Looks like a plan to me, and the results substantial."

Go ahead, find the best most complete an rational plan anywhere on line.

Post it.  If it provides how things are to be accomplished in general, how much it should cost, and how much benefit it would provide according to the models, it's a plan in my mind.

The MIT study group says the Paris TARGETS are worth 0.1°C by 2050.  We can't measure that.

Like I alluded to, there is a huge difference between a plan, of which there are many, and "a plan that satisfies CincyDawg," which has never and will never exist.

I think my criteria are very reasonable.  In order to do any kind of cost/benefit analysis, one needs an estimate of both.

Or, we can all just wave our hands and sing songs and expect politicians to DO something.

It's ridiculous.  And for folks out there to THINK governments are really going to tackle this issue is amazing to me, a complete lack of any rational analysis.

I liken it to the debt/deficit issue.  Politicians promise to DO something, without any coherent plans, and then of course if elected they do nothing.

I agree, though in large part the politicians don't do anything because we don't want them to do anything.

All Cincy asked for was a rough outline of the steps needed, along with an educated guess of their costs and benefits. 

The fact that such a plan "has never and will never exist" is rather telling. You need to provide a helluva lot more information than that, just to acquire a small business loan.

Rock Dust Could Be Farming’s Next Climate Solution
The process, called enhanced weathering, could remove 2 billion tons of CO2 from the air while fertilizing soil

For farming, the latest climate fix isn’t especially high tech or glossy. By spreading rock dust over large swatches of land, carbon dioxide could be trapped in transformed, scrubbing it from the atmosphere. If this technique, called enhanced weathering, were to be employed around the world, scientists estimate two billion tons of carbon dioxide could be removed from the atmosphere each year.

In a paper published in the journal Nature July 8, researchers at the University of Sheffield laid out the potential costs and impact of the process. If the three countries that emit the most carbon dioxide —China, the United States and India—adopted the practice, one billion metric tons could be scrubbed from the air.
Enhanced weathering essentially speeds up natural processes of erosion and chemical reactions using newly introduced minerals. During the process, rocks are crushed and transported to farmland, where they are spread over a large area once a year, reports Lyndsey Layton at the Washington Post. When it rains, water dissolves silicate or carbonate materials in the dust. This cycle causes carbon dioxide to be pulled from the atmosphere into the solution, forming bicarbonate ions. 

Over time, these ions are washed into the ocean and form carbonate minerals, trapping the carbon for at least 100,000 years.

Though the technique could be applied to any large swatch of land, many farms are already equipped to spread rock dust due to the common practice of enriching cropland with crushed lime, writes Nathanael Johnson at Grist. The minerals in the crushed rock could further fertilize soil, as long as metals and organic materials are not added to crop fields.

“Spreading rock dust on agricultural land is a straightforward, practical CO2 drawdown approach with the potential to boost soil health and food production,” David Beerling, director of the Leverhulme Centre for Climate Change Mitigation and lead author of the study, tells the Washington Post. “Our analyses reveal the big emitting nations — China, the U.S., India — have the greatest potential to do this, emphasizing their need to step up to the challenge.”

To meet the guidelines in the United Nations Climate Change Paris Agreement, some scientists claim at least ten gigatons of CO2 must be extracted from the atmosphere each year, the authors write. If the global surface temperature were to cross 3.6 Fahrenheit above preindustrial levels, scientists warn that the effects would be irreversible.

“We have passed the safe level of greenhouse gases,” James Hansen, a partner in the study and a climate scientist at Columbia University’s Earth Institute, tells the Washington Post. “Cutting fossil fuel emissions is crucial, but we must also extract atmospheric CO2 with safe, secure and scalable carbon dioxide removal strategies to bend the global CO2 curve and limit future climate change.”

Other methods of removing CO2 from the air include sequestration, in which CO2 from a factory is absorbed into a liquid or solid and stored. Enhanced weathering bears about the same cost, but has added agricultural benefits.

However, in order to meet the expected demand for rock dust, mining and grinding operations could require the same amount of energy as 10 to 30 percent of the CO2 captured, the study reports. To mitigate this, excess rock from industrial projects could be crushed and spread to limit the need for new mining.

The authors write that their plan offers “opportunities to align agriculture and climate policy,” but acknowledge that “success will depend upon overcoming political and social inertia.”

Spreading rock dust on half the farmland in the U.S. would cost $176 per ton of carbon and $225 annually per American. That’s pricey compared to clean energy solutions that directly cut emissions. Solar farms, for instance, cost less than $40 per ton of emissions cut, according to Grist.

To clear the atmosphere of greenhouse gasses to the degree necessary over the next several decades, the international community will have to remove existing carbon in addition to cutting new emissions, the Intergovernmental Panel on Climate Change notes.

You misunderstand. Plans exist, but no matter how precise, detailed, and exacting, he will poo poo them.

He isn't asking for one that is precise, detailed or exacting. He is asking for a rough outline of the steps that we need to take, and what they might cost and accomplish. If "plans exist" then it should be rather simple to drum one up that meets his criteria.

There is no tangible plan right now. Predictions to decimal degrees are foolish at best.

The climate is not predictable, for a number of reasons. I use models all the time, to try and predict flooding. That's the best I can do, is predict. The outcomes are always different, for a number of reasons.

China (and others) will not stop using Iran's cheap oil.

Yes, let me do a bunch of work so I can be told it will never happen. Sign me up for more of that.

Coming up with a rough outline for a course of action should be step one. That should have already been ironed out, before they tried to sell it to the public. "Give us billions of dollars so that we can maybe come up with a plan down the road" is not a plan.

Economists like carbon taxes. I would agree they would probably be the simplest and most effective solution. But taxes aren't popular, especially taxes where the entire point is to make things more expensive.
