I suspect this is an example of someone having a notion and then looking for excuses to do it.

Would you believe me if I told you, that we now have the advanced technology to safely scrub a minimum of (one) billion tons of carbon out of our atmosphere, to cool and rehydrate our dying planet, year after year after year? . . .

Gone are the “monsoons of old” . . .

We can bring back the pre-industrial “monsoons of old” and re-establish the continuity our planet needs to correctly sequence between contrasts. . .

We remove any barrier that blocks the ocean’s ability to F – L – O – W into/onto the desert land below sea level. . .

Deserts which consumes approximately (one / third) of the earth’s surface – without water – are bastions for suffering and are basically useless. . .

As the oceans continue to rise due to ice melt, the vast holding capacity of our deserts will help alleviate coastal flooding. . .

After years of desert irrigation from the ocean, pools of excavated saltwater ponds will be able to grow Dutch sea kale, and Sargassium muticum for sources of local food and energy. Deeper pools may also be able to sustain the Mediterranean sea fish (Tilapia) as they can survive saltwater to (44) parts per thousand . . .

Well, the global monsoon varies on a long cycle.

It covaries with various geological cycles including those caused by the geometric changes of the Earth's orbits. The 20,000-year precessional cycle of the global monsoon, for example, is responsible for the collapse of several Asian and African ancient cultures at ~ 4000 years ago. The same cyclicity is seen in the chemical composition of the air, such as methane concentration and isotope composition of air-bubbles captured in ice cores.

Now Wang found that the long-term cycles in the oceanic carbon reservoir also has a global monsoon origin.

This is new science and poorly understood: "the mechanism of how monsoon drives oceanic carbon cycle remains unclear". But the notion of “monsoons of old” seems broken, and tinkering designed to alter monsoon cycles without knowledge of such things seems broken too.

I'm not sure that we want more Salton Seas anyway. The one we have was an accident, and it is an increasing problem for many reasons. In general, a water body that has no reliable source and no outlet degrades monotonically over time unless it is so large - like an ocean - that it self cleanses to a great degree.

I found no online version of the article, it came in as an attachment to a Ken Caldeira message on the geoengineering list.
