I think it’s because most current futuretech solutions are pipe dreams at best. The scale of the problem is such that we need to learn how to essentially execute a planned terraform of a planet in the near term (as opposed to the current unintentional terraforming), using tech we don’t yet even have scribbled on a the back of a napkin to create massive effects on the planet using processes we don’t fully understand. It’s the equivalent of saying “to fix this we need to invent warp drive and genetically bioengineer human bodies to withstand prolonged periods of 100G acceleration and figure out how to extend human lifetimes to thousands of years, and we need to get it done in the next century.” It’s a fun fairy tale. The alternative, lifestyle changes, is better understood and the effects of which are easily predicted, but is only effective if done in a unified manner at a scale that current human nature will not allow. We can’t even figure out how to cure hunger and poverty in a world of plenty, good luck getting everyone to make the dramatic changes to even get us to stabilize at mostly broken planet. The real answer is that beyond a deus ex machina there is no answer and that the inevitable easily and indisputably modeled result of the current situation is dramatic near-term biosphere changes, ecosystems collapse and likely the end of most advanced human civilization within a couple centuries, conservatively. It must be a weird time to be a climate scientists, with the best computer models that have ever existed essentially returning a result that ends the world within a half dozen generations.
