My personal favourite is the wedge stabilization proposed a number of years ago now.
Because it's not one solution, it's many, so it gives lots of different options. Some countries would be able to do more in some categories than others. Doesn't matter with this concept.
as I expect you're aware, there's an assortment of 40-50 year roadmap type strategies that project how to realistically reduce fossil-fuel reliance. Typically, most denier types will speak of technology gaps; that the roadmaps can't be scaled properly and accordingly, suggest there's no point in even starting/trying... they of the, typically, Adapt-R-Us only approach.
Which kinda helps prove my point that people who spend their lives in suburbs and are not really connected with the natural environment beyond a trip a couple times a year to a friends lake lot see AGW as a bunch of BS. But the folks who farm, hunt, hike and explore the remaining natural areas are seeing the first effects and things like MPB are the proverbial canary in the coal mine.
Here's a song you might enjoy.

agreed. I also scuba-dive but, for the most part, have been able to pick locations unaffected by much/any acidification... but I most certainly know it exists and where it's most prevalent/damaging today. Thanks for the vid.
