Clarke was probably aware of the following (from wikipedia's article on Iapetus):

In the 17th century, Giovanni Cassini observed that he could see Iapetus only on the west side of Saturn and never on the east. He correctly deduced that Iapetus is locked in synchronous rotation about Saturn and that one side of Iapetus is darker than the other, conclusions later confirmed by larger telescopes.

Besides being a carbon sink, trees also scrub pollution and hold groundwater, working to prevent landslides.

"Although forests do release some CO2 from natural processes such as decay and respiration, a healthy forest typically stores carbon at a greater rate than it releases carbon."

I think you're wrong:

"To grow a pound of wood, a tree uses 1.47 pounds of carbon dioxide and gives off 1.07 pounds of oxygen. An acre of trees might grow 4,000 pounds of wood in a year, using 5,880 pounds of carbon dioxide and giving off 4,280 pounds of oxygen in the process."

So does the US. The Constitution gives the government the power to coin money. The Fed gives the government zero cost borrowing. The Modigliani-Miller theorem of finance shows that how you finance a good idea doesn't matter. If climate engineering is a good idea, we can finance it.

Finance should never be used as an excuse not to carry out a good idea.

I've watched Voyager too. I challenge you to cite sources about the scarce resource aspect.

The characters don't ever talk about the holodeck or replicators as being a scarce resource. They don't think in terms of scarcity. It's a post-scarcity society. Any scarcity is being imposed by your brain, not by the script-writers.
