“By far the largest greenhouse gas is water vapor, 86-90% according to the EPA. “
Let’s run with that. My solution is to clean up every polluted river in the world. The 10 most polluted rivers as of 2019 are:
1. Ganges
2. Citarum
3. Yellow
4. Sarno
5. Buriganga
6. Marilao River
7. Mississippi
8. Jordan
9. Matanza
10. Yamuna
Get those clean. We have the technology to remove all the crap from the rivers. However, we will also need to clean the water. Therefore my proposal would be to build Desalination facilities along the coasts, construct pipelines to take clean water to the rivers as well as to inland populaces that presently do not have clean water for drinking.
From this, we would see new economies coming to life as food can now be grown as well as new forests appearing. For the pipelines I would go so far as to say that if you create pipelines that use its outer surface as solar collection vehicles and put transformers near them, you can also power cities.
This can all be done for under 1 trillion dollars, which we would collect from the IMF and countries that are impacted by this. Let India and China pay for their problems.
And that’s your Green New Deal.
