I definitely agree, but in the meantime we cannot depend on these strategies when making long-term plans to combat climate change because we don't know whether their side effects will prove to be tolerable.

How do you know that the "long-term plans to combat climate change" won't prove harmful in their own right? They would produce massive economic effects at a minimum. Then there are the unknown effects of (e.g.) removing a lot of energy from the desert and transporting it to other regions. I'd be very surprised if that didn't have some effect. Same thing with extracting energy from the winds on any large scale. Wind energy turned into electricity is energy that's not available to (e.g.) move rain clouds from one region to another.

And so on.

In general the incoming power from the sun is so many orders of magnitude greater than the amount of power we usefully extract that it's hard to imagine it having any material impact on the biosphere.

The physical presence of solar cells and wind turbines is a different matter, but it's largely a local effect.
